yasmine_mansour — 2018-10-20 15:28:22 UTC

Pesticides, Fertilizers and Greenhouse were riding a Balloon, the balloon got so heavy.
Only one of these methods can now stay in the balloon and we have to get rid of two of them.
Your task is:
Based on the table of comparison given to you by your teacher:
1- Choose which method should stay and which methods should leave. Support your answer by its advantages over other methods and mention the disadvantages of other methods.
2- Compare and contrast the different methods mentioning how each one is used and how each method is effective.
4- In your own words, write an essay that includes the points above. *It should not be less than 200 words.*

5-Write your name in the title box so your teacher can know who you are.
6- You are expected to show your communication skills through commenting on two of your colleagues' essays.

P.s Attached is criterion D file.

I was once on a balloon with fertilizers, pesticide and green house. After we took off i realized that the balloon was getting to heavy and i had to let go of 2 of the methods. Which 2 will i choose? Well here's my answer.
I would have to let go of pesticide and fertilizers. Why you may ask? Well because pesticides and fertilizers are the same thing, well almost. Pesticides are made to kill insects but they also kill plants and fertilizers are supposed to "fertilize" plants but they are really harmful for the human, environment and even the plants. Besides, green house has a solution but first were supposed to know the problem. Green house is a place where people store plants (its made of gas). The problem is that all the plants are in one small closed area. what if the plants need to be out in the environment? A solution is to completely forget and ban green house. But i would still let go of fertilizers and pesticides since they are more harmful for us and all living things.
Pesticides and fertilizers are harmful for the environment you shouldn't use them. they're harmful for all living things.

Pesticides, Fertilizers, and Greenhouse were riding a Balloon, the balloon got so heavy.
Only one of these methods can now stay in the balloon and we have to get rid of two of them.
So I chose to get rid of pesticide and fertilizers. Because pesticide kills insects which harm other environments, and insects help in other stuff, like helping growing plants and they are food for some animals so they are helpful for the environment. And I will get rid of fertilizers because they can be so harmful to humans sometimes, and maybe even toxic. Some fertilizers cause death because if someone breathes chemical fertilizer he may actually choke to death. Though they can be helpful sometimes, sometimes fertilizers can be made out of natural resources which makes it less dangerous. But still we want a method with least disadvantages. That's why I chose greenhouse. Greenhouse is simply a glass building in which plants that need protection from cold weather are grown. The greenhouse has a lot of advantages like it provides a suitable temperature for humans plants and animals. It also sends unwanted solar energy to space. It controls the amount of water level on earth; like ice melting and it limits the polar caps to the polar regions only. While on the other side it may have disadvantages. Since greenhouse gases help to control and maintain the temperature, the primary effect of the increase in greenhouse gases would be on climate. This would mean warmer summers with natural disasters. Hurricanes have become common in recent years. Global warming would also affect the weather pattern. Rainfall would become erratic in many parts of the world. This might eventually lead to desertification. Overall, all of these methods have disadvantages and advantages in my opinion greenhouse was the best let me know if you agree i.

I think that if there were 3 methods (fertilizer) (pesticide) (greenhouse) i would choose fertilizer because fertilizers are used very easily and it also fertilizers keep plants healthy.

First fertilizers are used very easily. First minerals are dissolved in water can be absorbed through the plant roots .Fertilizers provide the plant roots with the essential chemical elements needed for the growth. Particular they are nitrogen and potassium and phosphorous n|k|p.

Second fertilizers are better than pesticide are toxic to people so if us students tried to use it (pesticide) we can die. I believe that pesticide doesn’t help it grow it just protects it because pesticide just kills worms and bugs and doesn’t help the plant grow and if you eat any fruit or vegetable you get cancer therefor pesticide id very very very horrible.

That’s why I think we should use fertilizer not pesticide .

Fertilizers, pesticides, and greenhouse were on a balloon and it wasn't steady because the weight was too heavy so two ways had to get off the balloon so it wouldn't fall, I suggested that the balloon should carry the fertilizers and leave the pesticides and the greenhouse. I chose the fertilizers because they improve the structure of the soil and increase its ability to hold water and nutrients. Over time, organic fertilizers will make your soil–and plants–healthy and strong, if you put fertilizers in the soil whatever plant you are growing will grow perfectly healthy and it also grows faster. The disadvantages is that sometimes fertilizers can make plants that weren't needing nourishment grow faster and healthier as also that some fertilizers aren't as healthy as organic fertilizers. Pesticide would be my last choice because Pesticides pollute air, water and soil. Carried by the wind, pesticide suspensions contaminate other areas. it also reduces nitrogen fixation, contribute to the disappearance of pollinators, threaten fish, and destroy bird and animal habitats. Pets may also become affected by strong pesticides. .I didn't pick green house because Water level balance of the earth would be destroyed. Polar ice caps would melt leading to an increase in the ocean level. Floods will inundate low lying areas.Marine life and ecosystem would be destroyed. and if there is rain or thunder the glass might break and it also might fall on the plants and ruin it. Also considering that greenhouses are expensive to build,heat,and to pay for water bills you also have to have constant monitoring, maintenance, and care. Fertilizers are the perfect solution to increase plants growth and health.

Fertilizers,pesticides,and greenhouse.I think i would choose fertilizers because fertilizer make plants to grow so easily and smoothly and it contains something called nitrogen & pottasium ,phosphorus.

First, i think that pesticides are not good and they can also harm all living things.And roots can harm or be distroyed quickly so the plants can die for sure.thats what i think for pesticides..

Second,i will be talking about the greenhouse so what i learned from it that it can bring water vapor and make a sun heat on earth and thats for sure is not good so thats why they call it a greenhouse so anthor reason why i did not choose the green house.

Third, iam going to talk about the fertilizers forget all the things said about the previous points that is difficult than others and more interesting for me and you. so fertilizers all good for all living things especcialy for plants, because they make plants grow quickly and easily&smoothly so the roots can not be distroyed or ruiened because its a fertilizer.

Thats why i choose fertilizer and also cause its more healthy !!!!!

Imagine if you were a farmer and you had to choose between 3 choises to increase your crop (Fertillizers),(pesticides) and (green house) If i was a farmer i would 've chosen the green house .Why? I would 've chosen it because it's a natural way to increse my corp without using chemicals and unnatural substances instead my corp woulo be healthier and cleaner and would grow faster .

Imagine this with me. So now you are a farmer and you have a choice between 3 things that will help you in farming. The first choice is fertilizers which are minerals dissolved in water that can be easily absorbed in the plant roots. They also provide the plants with the chemicals it needs to grow. Pesticide is fast acting, but is harmful for the enviroment. Finally, you last choice is greenhouse which in my opinion is your best choice. It's a place where the conditions of photosynthesis are more easily controlled than in the open outdoors. So, the choice is yours, what's it going to be???

Imagine that you have a backyard at your house and it is full of many crops. You want to make them grow faster, but you don't want to harm them. You search online and find three methods, but you can only choose one of them to use. The first method is fertilizers, which is a method that provides the crops with minerals, nitrogen, potassium, and phosphorus. The second method is pesticide, which kills pests and other animals that eat these crops, but it is really harmful to the them. The final method is greenhouse, which gives artificial light to the crops and allows photosynthesis to continue at night. Now I am going to be stating the most useful and safe method in my opinion.

In my opinion, fertilizers are the best way to increase the crop yield. Fertilizers are materials that provide crops the essential chemicals that are needed for the growth of crops. In the normal soil that is used to plant them doesn't have these nutrients required for them, so they tend to grow slowly. I believe that pesticide is a really harmful method for crops. Even though it kills these pests, it also lowers the health of the plants and may kill it, so what's the point of pesticide? The last method which is greenhouse isn't really harmful, but i don't think it's the best way. First, photosynthesis is a process that occurs naturally. I don't think it's a good idea to change that process and give the plant artificial light. It might have a big change in it's health.

In conclusion, I believe that fertilizers are the best method to use to increase the crop yield. It is much more healthy than the other two because of so many reasons, it's all up to you, so what will you choose?

There are many ways we can use to increase the crop yield. Crop yield is the measure of grains or seeds generated from a unit of land expressed as kilograms per hectare. Also called agricultural output. But there are some that have advantages and some that have disadvantages and advantages too. Three of the ways we can use to increase crop yield are fertilizers, pesticide, and greenhouse. But only one of them is good to use, that has less disadvantages and more advantages.
Fertilizers come in dry and liquid form they feed the plant with the chemicals and nutrients required for growing the plant. Fertilizers is a substance added to the soil to increase its fertility. Fertilizers are made of nitrogen, phosphorus, and potassium. Some types of fertilizers, such as chemical fertilizers have disadvantages. Chemical fertilizers are made of non-renewable sources, such as fossil fuels. Fertilizers grow plants but they don't strengthen the soil. And fertilizers can make him/her choke to death.

Pesticide is a substance used for destroying insects or other organisms harmful to cultivated plants. Pesticide has many disadvantages, one is they cost a lot of money to buy equipment and pesticide, and they are not involving selection of the most suitable or best qualified, and they are also harmful to the environment. Some advantages are they are fast acting and they are less manual labour. But there are more disadvantages.
Greenhouse is another way to increase crop yield. Greenhouse is a glass building in which plants that need protection from cold weather are grown. The conditions of photosynthesis are more easily controlled than in the open air outside. The artificial light allows the photosynthesis to complete even after the sun is gone. So greenhouse doesn’t have disadvantages
To conclude, greenhouse is the best way to grow plants because it doesn't have disadvantages, but the fertilizers and pesticide can be harmful to the enviroment.

If you ever had a planting project, and you needed an expert's advice, you will most likely go to a farmer. A farmer's most effective advice is to use fertilizers, because pesticides can include chemicals that affect people's health and can cause major diseases, so you probably don't want that in your life ,right? And the most amazing way to plant a full garden,is by using a greenhouse, a greenhouse is a closed area that is made of glass for sunlight to pass, and it is very wide and you can add whatever fertilizers you need or want,your most effective but easy ways to plant is by using a green house made of glass or any transparent materials,
also use organic fertilizers not any cheap fertilizer that you find in stores you won't believe,
but fertilizers which are in the organic side are actually and simply made out of dog poop,
I know disgusting but it helps the plant in a very effective way. It has some original natural nutrients that the plant usually need. Some advantages of using the fertilizers are they are 100% organic and so reliable. The advantages of the green house is that it allows photosynthesis in both day and night, so the plant can absorb water, sunlight and minerals as normally as a normal wild plant. The disadvantages of using pesticides is plant death and people's deadly diseases going on, for pesticides have non organic materials but indeed it has poisonous chemicals. The Fertilizers are effective for they are organic and 100% made of nature. They help the plant develop and grow a lot more faster, and the crops don't get filled with poisonous chemicals that will definitely affect people's health status.

Farah ahmed 7b. Have you ever went to a farmer, and wondered how do they increase their crops big, and healthy its actually pretty easy there many ways you can do it. I am going to tell you about ways/steps to increase your crop yield weither you are a beginner farmer, or even want to start out in your own backyard lets cover a few points to get healthy, and well grown crops.

farahfawzy54 — 2018-10-23 18:36:59 UTC

You are going to want to grow as early possible the earlier the better. You should also plant in high quality soil for better growing, and healthier crops, or even plants in general just make sure you do it correctly and secured. Now that we covered the steps u should have a healthy, and big crops, but we are not done yet if you need an extra boost there are tons of ways to increase, or give your crops a little boost like fertilizing in my opinion i think its the best way to give your crops a little boost there easy, cheap, fast, and they work like a charm. You can even use dog poop as your source of fertilization as disgusting as it sounds it actually worked see for yourself.

If you want to grow healthy, big crops one day always make sure of the soil, the ferzeitiaton, and etc...... Its very important to keep those things in mind when starting out

There are three ways to make plants grow faster and they are greenhouse , pesticides , and fertilizers.
I think that greehouse us the best because it helps in stopping global warming because it takes all of the carbon dioxide that is produced by factories so it decreases air polution while pesticides and fertilizers don't help in this in addition that they are unhealthy because it has chemicals thst are harmful for our body.
These chemicals that are added may cause bad disease like cancer.
Also greenhouse provides a longer growing season.
It also grows the crops in any weather while pesticides and fertilizers grow in the suitable weather because it is an open air place were your farm is but if it is in the greenhouse it would be better because you can control the temperature so you can grow the crop at anytime you want.
So I think that greenhouse is better than pesticides and fertilizers.

I think that the fertilizer should stay and pesticide and the greenhouse should leave. I chose the fertilizers over the others (pesticide and greenhouse) because fertilizers is the safe way to grow crops faster and stronger. It also uses nitrogen, potassium, and phosphorus which is needed in growing crops. The pesticide is really harmful because it acts among pests, It is harmful for the environment by making them died, they are also expensive to buy and nonselective. It acts fast but as you read its harmful. The greenhouse it is not harmful but it is not as fast as the fertilizer.it makes photosynthesis happen also not in day light hours. Fertilizers provide minerals dissolved in water . it can also be absorbed through the plant roots. The fertilizers provide the plant with the essential chemicals and also elements used for their growth. Particularly they are nitrogen, potassium, and phosphorus. (n\k\p)

First I want to say that the crop yield is an important thing to live and also to eat. I think if we compared the three of them we will see that the greenhouses are more suitable than any one of them because it doesn’t damage anything like countries, people or crop yield. The concept of agriculture is a key in understanding the importance of the crop yield. Now I will tell you some tips and methods you go with to increase the crop yield 1- you always have to choose the right time to plant.2- you have to understand how planting recurring do can affect the crop yield.3^rd: It’s important to ensure that the crop yield have enough water to grow also developing drainage system in your crops can prevent water logging.

Now I am going to talk about how does the greenhouses increase the crop yield, greenhouse plastic can really help they because they are original and it has a high quality of plastic it can help farmers increase their yields in a short period of time and the plants absorb the light very quickly. Farmers can use greenhouses constructed from glass or alternative materials to get more light to the plants. What I want to say is that the greenhouse are better than anything else.

I think fertilizers are the best choice because it can absorb through the plant roots and it provides the essential chemical elements needed for the plants growth they are actually kind of nitrogen and potassium and phosophorus .while the others like pesticides are expensive and non selective which means it harms pests and humans and its harmful for the environment and the greenhouse are artificial lights it only allows photosynthesis to continue only in daylight hours.

I think we should keep fertilizers and get out pesticides and greenhouse,because fertilizers are natural and they are minerals that dissolve in water and can be absorbed through the roots it also has essential chemicals that helps the plant in growth and the plants need it, so that is so important for the plant.The pesticides are fast acting acts against a wide range of pests ,less manual labor but they are so expensive to buy equipment and also pesticides non selective also its harmful for the enviroment,so it can help the plant a little bit but its so expensive and it will harm our enviroment,that's why its not good.Greenhouse where the conditions of photosynthesis are more easilly controlled than in the open air outside,artificial light inside the greenhouse allows photosynthesis to continue byeond daylight hours,greenhouse helps in photosynthesis but it helps it with artificial light and artificial light is not good for plants also it helps in daylight only.Thats why I think fretilizers is the best choice because it has menirals for that absorbs through the roots and essential or important chemicals that helps the plant for growth and thats so important.

Greenhouse where the conditions of photosynthesis are more easily controlled than in the open air outside. Artificial light inside the greenhouse allows photosynthesis to continue beyond daylight hours. Thats why I think that the greenhouse are much better even though the fertilizers provide the plant with the essential chemicals and pesticides are against pests, but I think it is greenhouse . Because it allows artificial light inside a greenhouse and allows photosynthesis to continue beyond daylight hours which means that it basically provides light and allows photosynthesis for the plant.

Humans require certain nutrients from food. Similarly, plants require specific nutrients in order to thrive. Unlike humans, plants cannot simply take a daily vitamin, but instead depend on their caretakers to provide the necessary nutrients for survival. Fertilizers Pesticide Greenhouse are all good inventions to use for planting but of course they have advantages and disadvantages. I think that the best way is using greenhouses because they don’t pollute the environment .In this essay I will compare the 3 inventions to prove that greenhouses are the best inventions to use which invention is the best for us to use in planting the first advantage in fertilizers is that it provides greener and heather plants ,contain anti-fungal , disease components ,it improves the soil structure and it also has the ability to hold onto water and nutrients increases. And its disadvantages are Sustainable and Environmentally Friendly because Synthetic fertilizers runoff into waterways polluting marine life.Pesticide for me is the worst choice, Pesticide’s first advantage that they have an economical way of controlling pests and it’s disadvantage is that it harmful for non-target species and it is also harmful for humans because it has some toxic chemicals. For greenhouses it can let you have Longer Growing Season because you can control over the temperature of garden and also you can prevent your plants from problems like rough weather (strong wind) and serious seasonal pests infestation (locust swarms, Japanese beetles, tent caterpillars, spider mites and many more).greenhouses can be a little bit annoying Since green house gases helps to maintain the temperature this will effect us because we will have warmer summers with natural disasters. Hurricanes have become common in recent years. So please try to help the environment by not using and fertilizers or Pesticide.

Farmers always have to make the decision of what method to use well, let me make this easier for the tired farmers and choose for them I believe fertilizer,pesticide and greenhouse are three smart ways to help increase crop yield but the best way in my opinion is the greenhouse. Because unlike fertilizers and pesticide it does not harm us it keeps both plants and humans safe. When using a greenhouse you don't have to worry at all about weather because the greenhouse trap,s the sun's radiation in the enclosure ,retaining the heat with in the structure.You also don't have to worry about growing season because it can be extended.Even in cold climate?Yes! Pouring pouring pouring what should you nothing because you can garden keep safe and keep the plants safe too.Another advantage is that plants will always keep safe from pests and predators.When using a greenhouse you save energy. And greenhouses allows plants to continue the process of photosynthesis beyond daylight hours.But there are also disadvantages like greenhouses can get very expensive. greenhouses call for continuous care and requires for a lot of bills like for water and electricity. Farmers turn to fertilizers because these substances contain plant nutrients such as nitrogen, phosphorus, and potassium. Fertilizers are simply plant nutrients applied to agricultural fields tosupplement required elements found naturally in the soil. Fertilizers have been used since the start of agriculture Why We Use Pesticides. Pesticides are used to control various pests and disease carriers, such as mosquitoes, ticks, rats and mice. Pesticides are used in agriculture to control weeds, insect infestation and diseases. ... Insecticides to control insects.pesticides and fertilizers also have very dangerous disadvantages pesticides cause many illnesses like cancer and may even lead to birth defects and is very dangerous for pregnant women pesticides are also very harmful for our environment and are also very expensive. these are the reasons why i chose the greenhouse and why i think it is the most effective way to increase crop yield

Green house

Pesticides, fertilizers and green house were riding a balloon, the balloon got so heavy. Only one of these methods can now stay in the balloon and we have to get rid of two of them. Well from my own personal standpoint the best choice to stay in the balloon is green house and fertilizers and pesticide should leave. First fertilizers wasn’t the best choice because of the following if we used it in an uncontrolled way can spoil the soil properties , osmotic pressure ,and water holding capacity . Also one big disadvantages when the excess nutrients from all the fertilizer we use runs off into our waterways, they cause algae blooms sometimes big enough to make waterways impassable. When the algae die, they sink to the bottom and decompose in a process that removes oxygen from the water. Now it’s time tell you why I didn’t choose pesticide to stay well it for lots of things. Primary because pesticides are non-selective, harmful to environment. Proximate after countless studies, pesticides have been linked to cancer, Alzheimer's disease, ADHD, and even birth defects. Pesticides also have the potential to harm the nervous system, the reproductive system, and the endocrine system. Well I think that’s enough disadvantages, let’s go to the green house therefore I can tell you why I chose it . well I chose the green house because of the following :

Ø Fresh greens, vegetable and fruit.

Ø Transplant availability and success.

Ø Fresh cut flowers all year long.

Ø A warm place to go in the middle of a cold, gray winter.

Ø Ability to grow things you wouldn't otherwise be able to grow (exotic flowers, tropical fruit)

Unfortunately everything has disadvantages so the disadvantages for the green house are that Greenhouse farming can get expensive. Depending on the material you intend to construction. If you choose a more useful greenhouse that is bulky and opaque over a well-designed greenhouse, they can take away from the aesthetic appeal of the overall garden. The water and electric bills will more than likely rise to heat and cool the inhabitants of the greenhouse. They also require constant care with maintaining the temperature, the residents and the structure itself.

Well that is why I chose green house because it can make us have fresh food and better life without any harm.

What is the best way to grow plants??

What do you think the best way to grow plants or crops??I think that the best way to grow plants is by fertilizers.Green houses are smart but they are not giving the actual sunlight. Pesticide is also smart but it can harm the plants,animals, or even humans.Do you think that fertilizers is a good method??
Most of the people now a days use fertilizers because fertilizers provide them with nutrients.Every plant needs nutrients,because plants need to be fertilized in order for them to grow beautifully and more productively.Pesticide is very harmful, because if you spray it on your plants it will harm them because they are chemicals and if you try to eat the plant it will harm you so much because it is chemicals and it might cause some serious health problems, some example of these health problems are cancer ant Alzheimer's deases. these chemicals affect any human that consumes them especially pregnant women, because pregnant women have babies inside their bodies, so it affects the mother and the child, this can cause mutation of the baby and some times even death.

looking for a way to increase your crops?well, there are 3 ways: fertilizers, pesticides and greenhouse.if were to choose which to use i would choose greenhouse. ask why?well because green house has light energy day and night. so more glucose is produced for the plant to grow faster. Greenhouse also doesn't allow most pests in since it is in a closed room. there are many uses of greenhouses, one way is: to shield crops from excess cold or heat and unwanted pests. A greenhouse makes it possible to grow certain types of crops year round .now why not pesticides or fertilizers?Well, for pesticides i wouldn't recommend it because while you are spraying it you can't breathe because it has chemicals that are harmful .it is also not selected which means that it doesn't kill pests it can also kill you.now why not fertilizers? because maybe one time the factory that produces these fertilizers add chemicals that are harmful.now, to compare between pesticides and fertilizers .Fertilizers, which come in dry and liquid form, feed the plant with the required nutrients. Pesticides are used on plants for eliminating, preventing, or controlling pests like; slugs, insects, fungal diseases (smuts, rots, and mildew), and snails. Plants generally require phosphorous, nitrogen, and potassium for its growth. The fertilizers contain all these in varying degrees and also contain other nutrients such as zinc and iron.

I think we should get fertilizers and pesticide out of the balloon and keep greenhouse. because fertilizers can be toxic for humans and pets. As well as nitrogen that's added to fertilizers to increase the stem and leaf production,can kill plants quickly if applied at a higher level than recommended. Fertilizers can cause environmental damage by harming the quality of drinking water. A type of fertilizers uses acids that can damage the soil and it prevents rain from entering the soil. Fertilizers produce fruits and vegetables with lower nutritional value and less flavor so as a result DONT BUY FERTILIZERS because your money will be wasted, soil conditions are undermined, and plants are not nurtured. Pesticide particles fly through the air when they are applied to the soil, if pesticide landed on species in both land and water the result can be low weight,loss of attention, or even death, some chemicals in pesticide can cause cancer, it also may irritate the skin or lungs. On the other hand greenhouse temperatures don't vary as much whithin a greenhouse, since the sun's ray is trapped in the enclosure, growing seasons can be extended even in cold climates, with a greenhouse everything is covered even if it's raining outside growing plants within greenhouse allows gardeners to go green, which is a benefit to the earth adding more plants helps to provide a fresher and clean atmosphere. Making a greenhouse is a great tool for fighting global warming

I think that I will keep the fertilizers and get rid of the pesticides and the greenhouse .if I get rid of the greenhouse the photosynthesis process will happen only at day and that will not harm the plant that means that nothing will happen and the pesticide can protect the plants from pests but its really expensive and it is harmful for animals and people. if you want the plant to grow faster you need to supply the elements of the plant and that is the goal of the fertilizers. Most fertilizers supply just nitrogen, phosphorus and potassium because the other chemicals are needed in much lower quantities and are generally available in most soils. Nitrogen, phosphorus and potassium availability is the big limit to growth. A pesticide is any substance used to kill, repel, or control certain forms of plant or animal life that are considered to be pests. Pesticides include herbicides for destroying weeds and other unwanted vegetation, insecticides for controlling a wide variety of insects. in green ouses One or two tomato crops can be planted in the greenhouse during the year. Planting, transplanting, and harvest dates will vary depending on location. As most tomato varieties will begin to ripen 100 days after planting, seed should be planted so the fruit begin to ripen soon after first frost for fall crops

I chose Fertilizers over all other things. The reason why I chose fertilizers because it provides the plant with more chemical element that help it in growth. As they are nitrogen, potassium and phosphorus. They can be said as “N/k/P” which stands for nitrogen, potassium and phosphorus. The reason why I got rid of the others is that I didn’t really like their reactions or how they work. I didn’t pick Pesticide because it is harmful for the environment. Even through it acts fast but it still is expensive to buy. Why would I buy something expensive that would harm my living area or environment? I was a little convinced with Greenhouse but the photosynthesis are easily controlled in the outdoors or the open air outside. We wouldn’t really need something that can get easily controlled in the open air.This is why I chose fertilizers. I don’t know about you but this was the effective one that could suit all. It’s not expensive, as it can be easily controlled anywhere outside or inside the house. As I said they can even make your plant grow faster. That is pretty suitable for all people. What do you think about it?

crop yield can be increased by the use of fertilizer and green house.
green house is beneficial due to the following reasons:
first

suitable for a lotof crops
Transplant availability and success to make a type of crops with more productivity.
A warm place to go in the middle of a cold, winter.
Ability to grow things you wouldn't otherwise be able to grow (tropical fruit)

fertilizer also increases the crop production without the harmful effect of pestiside. so not only increase the amount but also improve quality. low cost of the fertilizer make it easy and available all the time.

Crop yield is increased by 3 very different ways. 1.Fertilizers, 2.Pesticides, & 3.Greenhouses. Fertilizers are materials used to provide plants nutrients which are deficient in soil. Pesticides is a substance that is made of chemicals that is used to kill pests off a plant or animal. Greenhouses are buildings that provide plants with protection from cold and hot weathers.

Malak mostafa 7A ( final draft ) I choose fertilizers.Do you know what are the advantages and disadvantages of fertilizers?I am going to tell you about the advantages and disadvantages of the three methods,do you know what are the three methods?The three methods are fertilizers,pesticide,and greenhouse.I choose fertilizers because it provides the plant more chemical elements that will help the plant grow better.The advantages of fertilizers is, Fertilizers can expedite plant growth and help provide the farmers and nurseries,but they can also make toxic substances to the environment.Fertilizers help plants to grow faster and appear greener,fuller,and healthier. They also contain synthetic chemicals which do not biodegrade upon entering waterways and atmospheres.Do you know what are the uses of the three methods. The first method is fertilizers the uses of it is 1_ Gardeners and commercial growers use fertilizers.2_gardeners use fertilizers to provide additional nutrition to the plant.The plant will not find all her needs in the soil.Fertilizers can improve the yields in a vegetable garden or increase the flowering.3_As we said fertilizers help plants grow if plants grow faster so when they grow people can grow more plants and plants take of carbon dioxide and gives oxygen.The second method greenhouse,the use of green house is A greenhouse can extend a plant's growing season by a few weeks, or it can create a complete microclimate that's a successful substitute for the plant's native environment. From its origins as an indulgence for the wealthy and privileged, greenhouses are now used in many important and unexpected ways to help man understand and make use of the natural world. the last method is pesticide,its use is Algaecides to kill and/or slowing the growth of algae.Antimicrobials to control germs and microbes such as bacteria and viruses.Disinfectants to control germs and microbes such as bacteria and viruses.Fungicides to control fungal problems like molds, mildew, and rust.Herbicides to kill or inhibit the growth of unwanted plants, also known as weeds.Insecticides to control insects.Insect Growth Regulators to disrupt the growth and reproduction of insects.Rodenticides to kills rodents like mice, rats, and gophers.Wood Preservatives to make wood resistant to insects, fungus and other pests.Do you know what is the disadvantages of the greenhouse effect?It is in the picture.The disadvantages of pesticide is Pesticides are detrimental for the environment and produce considerable damage to ecosystems. Insecticides and herbicides may be harmful for non-target species. Pesticides pollute air, water and soil. Carried by the wind, pesticide suspensions contaminate other areas. Pesticides affect considerably natural biological equilibrium. Pesticides diminish biodiversity, reduce nitrogen fixation, contribute to the disappearance of pollinators, threaten fish, and destroy bird and animal habitats. Pets may also become affected by strong pesticides. thankyou the sources are • https://www.reference.com/business-finance/advantages-disadvantages-fertilizers-bc9ee075a6ac6000• https://www.hunker.com/13428274/uses-of-fertilizers• https://myassignmenthelp.com/blog/what-are-the-disadvantages-of-the-greenhouse-effect/

Science performance task Criterion C. I choose the fertilizers over other ways because I think it is the best way to increase crop yield. It absorbs the fertilizers through two ways, one is by the root system, the other is through foliage dressing. Adding a slow-release fertilizer during the initial planting is a good choice. Slow-release fertilizer allows a certain amount of fertilizer chemicals to be absorbed at one time. Fertilizers also uses nitrogen, potassium, and phosphorus which helps the plant grow. It provides essential chemical elements needed for the growth. Now I don’t prefer pesticide because it is harmful for the environment and sometimes dangerous for the plant. It is sometimes useful because it acts fast and against a wide range of pests. They are expensive to buy equipment and pesticide. Pesticides when applied at the right time and using the right amount, can save a crop from yield loss and increase yield overall. Another benefit would be the spread of disease. Humans have relied on pesticides to control mold and insects in homes. Control mitigates the spread of disease to humans. ex. the control of mosquitoes. It caused birds shells to thin and impacted certain bird species. Capital costs are high to build the greenhouse and install all the equipment. Operational costs are high compared to outdoor growing.Greenhouses, especially modern commercial greenhouses, are technical to operate and typically require training in addition to knowing how to grow plants. Plants grow from the sun,which is nature.cite:increasing crop yield using greenhouse advantages and disadvantages quora. By:Salma Ahmed Samir Grade\class: 7B Miss Yasmine Coolest teacher

so i choose to pick out the pesticides and green house, well of course you'll have to guess why? pesticide is something that kills bugs or worms any thing so the bugs couldn't chew the plants or any thing this is why i choose to pick out the pesticide because i think that bugs are not bad or anything. the green house is like a little glass house that you put in your plants to protect them from the weather. fertilizer i think is the best thing to keep because fertilizer is something that helps plants grow and this affects the plants growth. it is a little bit like the identical cells i guess in the mitosis. well here is a picture of it.

Pesticides, fertilizers and green house were riding a balloon, the balloon got so heavy. Only one of these methods can now stay in the balloon and we have to get rid of two of them. In my opinion, I will choose to keep Fertilizers and get out Pesticides and Green houses. Fertiizers has types one of them is the Organic Fertilizer and Organic Fertilizers is usually made from plant or animal waste think manure or compost. They can also be highly processed products with a compost or manure base. Also decomposition of organic matter creates a natural fertilizer, adding organic materials to the soil increases its to hold water, also decreasing the crusting of the soil, Natural Fertilizers are chemical free and can save you money. Greenhouses is more expensive also in construction, they also need a lot of care, if you choose a well designed greenhouse and its bulky then it will take most of the area of your garden, The water and electric bills will more than likely rise to heat and cool the inhabitants of the greenhouse, also greenhouse helps in photosynthesis but it helps it with artificial light and artificial light is not useful for plants and it helps in daylight only. are harmful for the enviroment also Pesticides pollute air, water, and soil. Also strong pesticides can harm pets or animals, they can destroy bird and animal habitats, Pesticide exposure is damaging to the immune system. So I think that the Fertilizers is the best choice because they are not harmful also they are natural or organic and they provide growth and many things for the plant, but Pesticides and Fertilizers are not useful for many ways like the Pesticides is so harmful to human and animals also they are not natural like the Fertilizers that’s why Fertilizers are better. Second thing is the Greenhouses and the Greenhouses is so expensive also they are not practical and when we compare it with the Fertilizers of course Fertilizers will be better than Greenhouses.

Green house

Final draft

Pesticides, fertilizers and green house were riding a balloon, the balloon got so heavy. Only one of these methods can now stay in the balloon and we have to get rid of two of them. Well from my own personal standpoint the best choice to stay in the balloon is green house and fertilizers and pesticide should leave. First fertilizers wasn’t the best choice because of the following if we used it in an uncontrolled way can spoil the soil properties , osmotic pressure ,and water holding capacity . Also one big disadvantages when the excess nutrients from all the fertilizer we use runs off into our waterways, they cause algae blooms sometimes big enough to make waterways impassable. When the algae die, they sink to the bottom and decompose in a process that removes oxygen from the water. Now it’s time tell you why I didn’t choose pesticide to stay well it for lots of things. Primary because pesticides are non-selective, harmful to environment. Proximate after countless studies, pesticides have been linked to cancer, Alzheimer's disease, ADHD, and even birth defects. Pesticides also have the potential to harm the nervous system, the reproductive system, and the endocrine system.Well I think that’s enough disadvantages, let’s go to the green house therefore I can tell you why I chose it .well I chose the green house because of the following :

Ø Fresh greens, vegetable and fruit.

Ø Transplant availability and success.

Ø Fresh cut flowers all year long.

Ø Ability to grow things you wouldn't otherwise be able to grow (exotic flowers, tropical fruit)

Farmers turn to fertilizers because these substances contain plant nutrients such as nitrogen, phosphorus, and potassium. Fertilizers are simply plant nutrients applied to agricultural fields to support required elements found naturally in the soil. Most farmers today use fertilizers that are either mined or manufactured

As for pesticides, Pesticides are used to control various pests and disease carriers, such as mosquitoes, ticks, rats and mice. Pesticides are used in agriculture to control weeds, insect infestation and diseases.

In addition green house are used in, extending a plant's growing season by a few weeks, or it can create a complete microclimate that's a successful substitute for the plant's native environment. In temperate climates, greenhouses extend the growing season and protect plants from harsh weather conditions. In higher latitudes, greenhouses increase plant production by optimizing the available light. Even in hot, arid regions, specialized greenhouses have been developed that can help lower temperatures and manage water loss in plants due to transpiration.

Some negative effects for fertilizers are the effects of chemical fertilizers are compounded when mixed with a single pesticide. Scientists discovered altered immune, endocrine and nervous system functions in mice, as well as influence on children’s and fetus's developing neurological, endocrine and immune systems. These influences "portend change in ability to learn and in patterns of aggression." With it's increased use and projections of future use, this problem may increase several fold in the coming decades.

Groundwater contamination has been linked to gastric cancer, goiter, birth malformations, and hypertension, testicular cancer⁴ and stomach cancer.

Nitrogen groundwater contamination also contributes to marine "dead zones". The increase in the water-soluble nitrates creates an influx of plant-life, which eats up oxygen and starves out fish and crustaceans. This has an impact not only on the aquatic ecosystem, but on local societies who depend on food sourced from those areas. And then there is the highly questionable use of raw sewer sludge as a fertilizer.

But as for pesticides they impose a serious negative impact on the environment. Excessive use of pesticides may lead to the destruction of biodiversity. Many birds, aquatic organisms and animals are under the threat of harmful pesticides for their survival.

Well that is why I chose green house because it can make us have fresh food and better life without any harm. What I mean is that pesticides can cause harm fir humans as I said in the essay, fertilizers can harm also people example: it can get cancer. Greenhouse has disadvantages effects but it doesn’t harm humans like fertilizers and pesticides.

Imagine that you have a backyard at your house and it is full of many crops. You want to make them grow faster, but you don't want to harm them. You search online and find three methods, but you can only choose one of them to use. The first method is fertilizers, which is a method that provides the crops with minerals and nutrients. The second method is pesticide, which kills pests and other animals that eat these crops, but sometimes it harms it. The final method is greenhouse, which gives artificial light to the crops and allows photosynthesis to continue at night. Now I am going to be stating the most useful and safe method in my opinion.

In my opinion, fertilizers is the best method to use to increase crop yield. Crops and plants need to grow and thrive, but it requires many elements that include nitrogen, phosphorus, and potassium. These are very important in the growth of crops and without them, the plants won't become healthy, thus it will die. These elements are included in fertilizers. I think that if you use pesticide to kill animals and insects, won't it also kill the crop? There is now proof that some of the chemicals that pesticide produce do have a potential risk to humans and animals and bad side effects to the environment. The world-wide deaths and diseases due to pesticide poisoning number about 1 million per year. The greenhouse method is using artificial light in order to make plants grow. It is a room made of glass or clear plastic to let in sunlight. But why not just put the plants outside? Photosynthesis is a process that occurs naturally. I don't think it's a good idea to change all the substances needed and the substances produced.. It might ruin the whole process and that will reduce its health.

In conclusion, the fertilizer method is the best method in my opinion. It helps the plant or crop grow faster, and it doesn't harm it but it actually makes it healthier. The other 2 methods have a lot of disadvantages and i think they should not be used in increasing crop yield.

I have once been on a hot air balloon with pesticides, green house & fertilizers. and well it was a terrible ride since i had to get rid of 2 of them because the balloon was getting heavy and i got rid of pesticides and green house. (47)

Ok so lets do this 1 at a time. i'll start with greenhouse. So first off what is greenhouse? a building, room, or area, usually chiefly of glass, in which the temperature is maintained within a desired range, used for cultivating tender plants or growing plants out of season. (copied link down below). i got rid of green house because a plant need oxygen sometimes..... there fore we need to stop using green house. And about pesticides. a chemical preparation for destroying plant, fungal, or animal pests. (I copied and pasted the meaning for all the words but i do understand it). pesticides are not only harmful for the environment but for the humans too. since the chemicals inside the pesticides are harmful to the human lungs, it is not preferred to use pesticides. (134)

Now lets talk about fertilizers.......so first off what is the best method that increases crop yield? well in my opinion the best method is to test different soils using fertilizers to see what fertilizer is the best for farming. Oh and how is this method used? It is used by taking a whole bunch of kinds of soil (for ex:- dry, fertile, too wet, ETC...) and using different kinds of fertilizers and seeing which one is the best. Oh and here are some advantages and disadvantages on fertilizers. (89)

Advantages (this has to do with organic fertilizer):-
1. soil structure: the soils ability to hold water & other nutrients is increased.
2. microbes thrive: carbon, nitrogen, phosphorus & potassium feed the microbes & makes nutrients for the plant.
3. plant damage: some fertilizers damage the roots and leaves which is less likely for organic fertilizers. (53)

Disadvantages:-

1. not all products are created equally: since they all are not created equally than you have to watch out for your fertilizers to make sure they are not dangerous.

2. Nutrition levels are low: in addition the organic fertilizers can be harmful to the plant & cannot give the pop of color that the chemical fertilizer gives.

Increasing Crop Yield

In my opinion If I had to use one way to stay from the 3 ways that are fertilizers ,pesticides , and greenhouse I would pick the green house for that you can plant fresh greens,vegetables, and fruits, also you have fresh cut flowers all year long, it is a warm place to go in the winter,you have the ability to grow things you couldn’t be able to grow ( exotic flowers, tropical fruit) , no animals ( squirrels, insects) . The disadvantages are that it is expensive to build and heat and that it requires constant monitoring it could increase electrical bills. Fertilizers are simply plant nutrients applied to agricultural fields to supplement required elements found naturally in the soil. While for the fertilizers excess or uncontrolled use can spoil the soil,&destroy water sources.pesticides are chemicals that are sprayed , the disadvantages for pesticides are that it can have poisoning hazards,residues in foods,and it pollutes the environment.The green house is not harmful for that it reduces sunlight or traps it and it gives the plant what it wants from nutrients while fertilizers and pesticides are the greenhouse can help grow more types of plants the plants that grow in the greenhouse ( a small glass building) grow all year around while in the 2 other methods they grow in a particular time

increasing crop yield

In my opinion the fertilization is the best method that increases the crop yield, but the pesticide will harm the crop yield. Fertilization is better because, first, Fertilization provide something called zygote which is an important thing for the plant. Also in fertilization process of increase something called the metabolic activities and produces protein. So, I think that the fertilization is better than pesticide and the greenhouse. While, pesticide is harm for crop yield. because, when the farmers began to put pesticide material on the crop yield, the crop yield began to not produce fruits and vegetables, the pesticide are very harmful for the crop yield. The similarities between the two ,are that they both are material and they both are used in farming. the differences between the two are that the pesticide is harmful for the crop yield, but the fertilization is very useful for crop yield. Also I want add something which is that fertilization provide the plant with the essential chemical elements needed for the growth and also I want to add something about pesticide which is that its done with a very large collection of pests, so these pests harms the crop yield so much. So I want say a small advise that is like a quote "use fertilization and not pesticide".

If you were a farmer and you had three options to choose from for your crops and the three options are fertilizers , greenhouse , and pesticides. What would you choose? Fertilizers minerals disolved in water can be absorbed through the plant roots , they provide the plant with essential chemical elements needed for the growth , particularly they are nitrogine and potassium and phosphorus N/K/P. Now the greenhouses are where the conditions of photosynthesis are more easily controlled than in open air outside and artificial light inside the greenhouse allows photosynthesis to continue beyond daylight hours . Last but not least I will be talking about the pesticides. Pesticides are fast acting acts against a wide range of pests , less manual labor but they are so expensive to buy , equipment and pesticides non selective , harmful to environment. That is all . Of I was the farmer I would choose had chosen hreenhouse just because they provide photosynthesis and let photo to continue beyond daylight hours. You may tell me that fertilizers and pesticides are better because it has nitrogen in the fertilizers and the pesticides qre harmeful to the environment. So I think that I chose the right choice because it is the best one till now . Thank you

Have you ever went to a farmer, and wondered how do they increase their crops big, and healthy its actually pretty easy there many ways you can do it. I am going to tell you about ways/steps to increase your crop yield weither you are a beginner farmer, or even want to start out in your own backyard lets cover a few points to get healthy, and well grown crops. You are going to want to grow as early possible the earlier the better. You should also plant in high quality soil for better growing, and healthier crops, or even plants in general just make sure you do it correctly and secured. Now that we covered the steps u should have a healthy, and big crops, but we are not done yet if you need an extra boost there are tons of ways to increase, or give your crops a little boost like fertilizing in my opinion i think its the best way to give your crops a little boost there easy, cheap, fast, and they work like a charm. You can even use dog poop as your source of fertilization as disgusting as it sounds it actually worked see for yourself.
It does have its pros and cons though fertilizer can be for plants

If you want to grow healthy, big crops one day always make sure of the soil, the ferzeitiaton, and etc...... Its very important to keep those things in mind when starting out

Increasing crop yield

I choose: Fertilizers

Because farmers use it to grow and also plants use it to make food faster because… wait a moment ..do you know what is the meaning of fertilizers its that minerals desolve in water can be absorbe through the plant’s root and also they provide the plant with the essential chemical needed for the growth and particularly they are nitrogen and potassium and phosphorus and if I was a farmer I would choose the fertilizers because it will let me farm more and give me money because fertilizers will let me farm more and the plants will be better and helthier, and it will help me to improve my self as a farmer and as a person by trading and buying a new products to make earth a better place by planting a lot of plants and trees which takes carbon dioxide and give oxygen to purify the air around us . And on the other hand personally the fertilizers let me have a good quality of fruits and vegetables .Fertilizers can be organic (composed of organic matter, i.e. carbon based), or inorganic (containing simple, inorganic chemicals).And their advantages and disadvantages the advantages oh I forgot to tell you that they are organic and chemical fertilizers and the advantages for the organic are: organic fertilizers break down, they improve the structure of the soil and increase its ability to hold water and nutrients. Over time, organic fertilizers will make your soil–and plants–healthy and strong.And more and also the disdvantages for the organic are: Organic fertilizers break down according to nature’s rules, so they may not release nutrients as soon as you need them. You have to be patient – you won’t see improvement overnight. In fact, you may actually see a deficiency in your plants during the first couple of months until the first application breaks down. Hang in there! You’ll most definitely be rewarded. And the advantages of the chemical are: nutrients are available to the plants immediately, improvement occurs in days.They are highly analyzed to produce the exact ratio of nutrients desired.Standardized labeling makes ratios and chemical sources easy to understand.They’re inexpensive. And the disadvantages of the chemical are: hey grow plants but do nothing to sustain the soil. The fillers do not promote life or soil health, and even packages labeled “complete” do not include the decaying matter necessary to improve soil structure. In fact, chemical fertilizers don’t replace many trace elements that are gradually depleted by repeated crop plantings, resulting in long-term damage to the soil. And there are some facts about the greenhouse are: hey grow plants but do nothing to sustain the soil. The fillers do not promote life or soil health, and even packages labeled “complete” do not include the decaying matter necessary to improve soil structure. In fact, chemical fertilizers don’t replace many trace elements that are gradually depleted by repeated crop plantings, resulting in long-term damage to the soil.

There are three different kinds for making plant grow faster and they are greenhouse, fertilizers, and pesticides.
I think that greenhouse is the best because it is sutaible at any time and at any whether. For example when we are at night it helps because photosynthesis do not stop so the plant is always getting energy so it can grow. That happens because the greenhouse is a building that stores the sunlight in its own way so it makes plants grow faster. Also greenhouse help in deacreasing the global warming And that is because it traps heat so it doesn’t spread all over the world and cause global warming.
Pesticides also help in making plants grow faster. It is sprayed and after it turns into gas or vapor it will be harmful because it causes potential harm which is volatilization and it spreads to other lands so it is really harmful for wildlife.
Next is fertilizers and they are applied to the surface of the soil and then work with the soil in a harrow. In the USA they discovered that when fertilizers are made there materials that are added to the fertilizers and they cause cancer. So fertilizers are usefulfor plants but not for humans and animals.
I see that greenhouse is the best because it is fast and also harmless.

pesticides, fertilizers, and greenhouse were riding a balloon. the balloon got too heavy. now we should keep one of them and get rid of the other two. I think that I will keep the fertilizers and get rid of the pesticides and the greenhouse .if I get rid of the greenhouse the photosynthesis process will happen only at day and that will not harm the plant that means that nothing will happen and the pesticide can protect the plants from pests but its really expensive and it is harmful for animals and people. if you want the plant to grow faster you need to supply the elements of the plant and that is the goal of the fertilizers. Most fertilizers supply just nitrogen, phosphorus and potassium because the other chemicals are needed in much lower quantities and are generally available in most soils. Nitrogen, phosphorus and potassium availability is the big limit to growth. A pesticide is any substance used to kill, repel, or control certain forms of plant or animal life that are considered to be pests. Pesticides include herbicides for destroying weeds and other unwanted vegetation, insecticides for controlling a wide variety of insects. in green ouses One or two tomato crops can be planted in the greenhouse during the year. Planting, transplanting, and harvest dates will vary depending on location. As most tomato varieties will begin to ripen 100 days after planting, seed should be planted so the fruit begin to ripen soon after first frost for fall crops. Pesticides are detrimental for the environment and produce considerable damage to ecosystems. Insecticides and herbicides may be harmful for non-target species. Pesticides pollute air, water and soil. Carried by the wind, pesticide suspensions contaminate other areas. Pesticides affect considerably natural biological equilibrium. Pesticides diminish biodiversity, reduce nitrogen fixation, contribute to the disappearance of pollinators, threaten fish, and destroy bird and animal habitats. Pets may also become affected by strong pesticideshttps://homeguides.sfgate.com/disadvantages-greenhouses-51338.html

I think we should get fertilizers and pesticide and keep green house because fertilizers are chemicals that are added to soil to supply nutrient to make the soil more fertile. The main elements in fertilizers are nitrogen which its elements works by increasing the plant’s capacity to produce new stems, flowers or fruit, and phosphorus helps the plants produce all of that nice organic stuff like oil and starch and potassium helps to build protein fight off diseases. Fertilizers can be toxic for humans and pets. As well as nitrogen that’s added to the fertilizers to increase the steam and the leaf production, can kill plants quickly if applied at a higher level than recommended. Fertilizers can cause environmental damage it can harm the quality of drinking water. A type of fertilizers uses acids that can damage the soil and it prevents rain from entering the soil .fertilizers produce fruits and vegetables with lower nutritional value and less flavor.so as a result DON’T BUY FIERTILLISERZE because your Money is wasted, soil conditions are undermined, and plants are not nurtured. And these are the pros of fertilizers 1- chemical fertilizers they are easy to store, transport and apply 2- the are rapid in action 3- constituent ratios defined .Pesticide is a chemical for the control of insects and weeds. Farmers often spray pesticides over crops like tomatoes and apples and other fruits and vegetables so fewer weeds and bugs means: more of tomatoes and apples. Pesticide particles fly through the air when they are applied, eventually sinking into the soil, if pesticide landed on species in both land and water the result can be low weight, lowered resistance to disease, sterility, loss of attention, and even death, Some chemicals in pesticides can cause cancer. It may also irritate the skin or lungs And there are pros as well like more plentiful harvest it means the unwanted pets like mice and insects eat plants at their early stages and destroy their chances of producing fruits or vegetables and is very easily available which means that pesticide are available in stores around the world. .on the other hand greenhouse is a building that is built out of glass. Glass is used because it lets the visible rays of the sun pass through which are then absorbed by plants during the day the visible light is converted to heat and then used by the object. greenhouse Temperatures don’t vary as much within a greenhouse, since the sun’s radiation is trapped in the enclosure, retaining the heat within the structure, Growing seasons can be extended, even in cold climates, With a greenhouse, everything is covered. Even if it’s pouring rain outside, you can garden and keep dry; growing plants within a greenhouse allows gardeners to go green, which is a benefit to gardeners and the earth. Adding more plants helps to provide a fresher, cleaning atmosphere, making a greenhouse a great tool for fighting global warming

Today we are going to talk about Fertilizers,Pesticides,and Greenhouses. They are methods in witch helps the plant to grow safely in different places.

OUR FIRST METHOD IS FERTILIZERS ;
Fertilizers are simply plant nutrients applied to agricultural fields to supplement required elements found naturally in the soil.Fertilizers have been used since the start of agriculture everywhere.
SOME OF PROS OF Fertilizers ;
-Support plant growth

In general, chemical fertilizers contain the primary plant nutrients that are made of nitrogen, potassium, and phosphorous, in specific ratios that are tailored for the specific growth requirements of specific crops, such as corn or tomatoes.These nutrients from fertilizers allow crops to be grown even in depleted soils because the plant’s basic nutritional requirements are being met.
-Grow crops fast and big

Because fertilizers provide the primary nutrients needed for efficient plant growth, plants are able to grow more quickly and larger than if they weren’t being fed the fertilizers.
-SOME OF CONS OF FERTILIZERS;
-Fertilizers can actually “burn” people, plants, and the soil

Synthetic fertilizers contain high amounts of acidic chemicals lot of acid, and can therefore burn the skin negatively impact soil quality, and burn plants¹.
-Fertilizers produce toxicity and pollution

In an all-too-common scenario, excessive nitrogen-rich fertilizers can runoff from farmland into water bodies when it rains, causing toxic algal blooms in rivers, lakes, and the ocean due to excessive nitrogen levels. Fertilizers can also leach through soil into groundwater, making it very harmful to the surrounding environment.
OUR NEXT METHOD IS PESTICIDES ;
A pesticide is any substance or mixture of substances intended for preventing, destroying, repelling, or mitigating any pest (epa.gov). ...Agricultural pesticides are then those chemicals that are used by farmers to prevent the effectivity of the pests on the growth and productivity of agricultural crops.
SOME PROS OF PESTICIDES;

Insects, mice, unwanted plants, fungi and microorganisms (viruses and bacteria) can damage crops, humans or other animals. Pesticides are designed to stop all of these pests, as well as herbicides and fungicides. Herbicides destroy unwanted vegetation and weeds. Fungicides stop the spread of mold and mildew.By stopping these pests in their tracks, pesticides protect your vegetation and stop disease-carrying organisms. This is particularly useful in your home garden to ensure higher quantity and quality crops. Any wooden structures in your garden will also be protected.
SOME CONS OF PESTICIDES;
Alas, pesticides are replete with problems. Since pesticides are designed to kill living organisms, they can harm humans, animals and the environment. They work because they are toxic. Pesticides cause a wide range of health problems, from birth defects and damage to the reproductive system to cancer, according to the Alliance for Healthy Homes.
Jenkins-Sutton recommends that pesticides not be used on lawns and gardens where children and pets play. According to the National Pesticide Information Center, infants and children are more sensitive to the harmful effects of pesticides than adults for various reasons: their organs and nervous systems are still developing, they breathe more per minute, and they are closer to the ground.
OUR THIRD METHOD IS GREENHOUSES;
97 percent of climate scientists agree that humans have changed Earth's atmosphere in dramatic ways over the past two centuries, resulting in global warming. To understand global warming, it's first necessary to become familiar with the greenhouse effect, though.
PROS OF GREENHOUSES;

Fresh greens, vegetable and fruit
Transplant availability and success
Fresh cut flowers all year long
A warm place to go in the middle of a cold, gray winter
Ability to grow things you wouldn’t otherwise be able to grow (exotic flowers, tropical fruit)
No more battles with squirrels and insects
Do more of what you love to do, longer Add beauty and visual appeal to a landscape

CONS OF GREENHOUSES;

Can be expensive to build
Can be expensive to heat
Requires constant monitoring, maintenance and care
Could increase electrical and water bills
May detract from aesthetic appeal of a garden

I think that greenhouses is the best to be used in crop yields because it has less cons and lots of very positive and helpful pros.And this refers to the info that I've gathered.

there are three types to increase crop yield. they are fertilizers,pesticides and green house.all have positive and negative effects. I will keep fertilizing and git rid of the other two. I choose fertilizing because it gives the plant nutrients like potassium, phosphorous, calcium and nitrogen . the nitrogen is the main element, that works on the growth of the crop and potassium help the plant to make proteins. phosphorous help the plant to git out all the organic materials that inside. but it also have harmful ,it can harm human and animals around. pesticides are increasing the crop yield, but it has many harms. it can be harm for not only pests but also for humans. it can effect your health negatively,and diseases.also if we use a large amount of it it will git us cancer. so we can not never use it. now the greenhouse. the greenhouse can harm the farmer working in. because in the greenhouse the carbon dioxid level increase so it will make health problems. not just that it also can git us diseases because its closed place and it does not have fresh air.

The plants is a living organisms that it needs a natural place with a clean water and a sun light Fertilisers is so good for the plants fertilizers is sometimes is harm the human but not all the time . Fertilisers is increase the fertility of the plans with natural way and if it not natural is can harm the plant not fix it . Fertilisers is very important for the plants because it help it and fix it and increase its fertility and this helps it so much . It’s right that the plants take energy from the sunlight and the mitochondria and chloroplast help it so much to be independent but some plants it fertility is too much small and it don’t benefit her so much. Is very important to the plants to but for them some fertilisers but sometimes when you increase the amount of it , may be it will die . The Fertilisers is have a large amount of the growth period of the plants it’s help it so much .Fertilisers contain minerals such as nitrogen, potassium and phosphorus, which help plants to grow. Fertilisers increase crop yields but cause the problem of eutrophication when they're washed into rivers and lakes by rainwater. Most chemical fertilisers are made by the reaction of an acid with an alkali.The plants is multicellular organisms and it also a type from eukaryotes .Not only the plants make their own think also the human should have a little Attention to it because it also a living think needs food, water , and a clean place .

Cir.D

Proper fertilization of greenhouse crops is essential for producing high-quality plants. Some nutrients such as calcium and magnesium may be mixed into the growing medium prior to planting, but most of the nutrients are applied after planting using water-soluble fertilizers. Fertilizer injectors are used by most growers to apply water-soluble fertilizers to plants. These devices "inject" a small quantity of concentrated fertilizer solution stocksolution into the irrigation line so that the water leaving the hose (dilutesolution) supplies the proper concentration of fertilizer. Applying fertilizers in a liquid form with a fertilizer injector is more convenient than broadcasting or top-dressing with dry fertilizers. Additionally, most growers apply water-soluble fertilizers at a dilute concentration on a "constant feed" basis (with every watering) to insure an adequate supply of the essential elements for plant growth.

Fertilizer Calculations for Greenhouse Crops. ... Parts per million is a convenient unit of measurement for indicating the concentration of fertilizer solutions. For example, it is often recommended that 150 to 250 ppm N be applied in the irrigation water on a "constant feed" basis for fertilizing many floricultural crops.

I think that fertilizers are better because, minerals dissolved in water can be absorbed through the plant roots. And they provide the plant with essential chemical elements needed for the growth, while greenhouse, where the conditions of photosynthesis are more easily controlled than in the open air. So, for me fertilizers are better that greenhouse cause it helps more in the plant growth

FINAL DRAFT

There are 3 methods of increasing crop yield. Fertilizers,Greenhouses, &Pesticides. Fertilizers are the materials used to provide nutrients deficient in the soil. Greenhouses are buildings that protect plants from hot and cold weathers. Pesticides are chemicals that are sprayed on a plant or animals to make them pests free. In my opinion i see that Fertilizers are the best method to use because they are the most natural way and they make plants grow bigger better and healthier. on the other hand greenhouses is a smart method because it provides plants with protection, but they are not the best way because it might fall on the plants and destroy them and break them.Pesticides is not the best method to use because it is harmful for the plants and for us too. pesticides can harm the plant because it might kill them because they are just chemicals, and they are harmful for use because when we eat the plant it will get into our body and it might get you some heart diseases cancer or even breathing problems and it might lead to death.
