Outline two hazards of artificial fertilisers that you feel are the most important and justify your choice. en-us 2019-02-11 04:13:52 UTC 2019-02-11 04:17:16 UTC hello@padlet.com Fertilizers - Veer Tandon, Musti phd https://padlet.com/tallah82_1/jibna8io2y3k/wish/329728901 Natural fertilizers are organic products that have been obtained from living things or from the earth. They can be either be derived from plants or animals.
Some examples would be mushroom manure, blood meal, bone meal, poultry or horse manure  and compost. 
Synthetic fertilizers are those composed of the synthesized chemicals of nitrogen, phosphorus and potassium. Fritz Haber is known as the father of fertilizers.

Direct exposure or contact of these fertilizers can kill babies and cause health problems in many people. 
Excess Potassium can also cause the loss of structure of the plant stem and cause calcium deficiency.
When the synthetic and unnatural force feeding of chemicals, can destroy the balance that is needed so that plants grow. ]]> 2019-02-11 05:20:04 UTC https://padlet.com/tallah82_1/jibna8io2y3k/wish/329728901 Soil https://padlet.com/tallah82_1/jibna8io2y3k/wish/329729643 There is an increasing concern that use of chemical fertilisers on soil depletes the soil of essential nutrients. As a result, the food produced in these soils have less vitamin and mineral content. Soil where chemical has been used has less, magnesium, potassium and calcium content.-Ethan, Trivi and Brahim]]> 2019-02-11 05:25:13 UTC https://padlet.com/tallah82_1/jibna8io2y3k/wish/329729643 Fertilizers- Jisha and Nayana https://padlet.com/tallah82_1/jibna8io2y3k/wish/329729694 Natural fertilizer, include compost, mulch and aged manure, as well as fish emulsion, bone meal, kelp and soybeans. Natural fertilizers depend on organisms in the soil to break down the product, thereby releasing these vital nutrients over a longer period of time, making them less likely to damage and burn the plants' delicate leaves, roots and stems. Natural fertilizers are organic products that have been extracted from living things or from the earth. They can be either plant-derived or animal-derived.

Whereas artificial fertilizer, usually has a higher level and a larger percentage of soluble nitrogen than do natural fertilizers. They are composed of the synthesized chemicals of nitrogen, phosphorus and potassium. In general, natural fertilizers contain lesser amounts of N-P-K than their synthesized counterparts, so you need to use more of them to supply the plant with the required amount of nitrogen, phosphorus or potassium. 

Harmful effects of artificial fertilizers:
Increases air pollution: Excess nitrogen used in crop fertilization can contribute to the release of greenhouse gases such as carbon dioxide and nitrous oxide into the atmosphere. This effect is caused by using a greater amount of chemical fertilizer than the plants can readily absorb. Excess greenhouse gases trapped in the atmosphere may be contributing to the increase of land and ocean surface temperatures.

Soil Acidification: 
The over-use of chemical fertilizers can lead to soil acidification because of a decrease in organic matter in the soil. Nitrogen applied to fields in large amounts over time damages topsoil, resulting in reduced crop yields. Sandy soils are much more prone to soil acidification than are clay soils. Clay soils have an ability to buffer the effects of excess chemical fertilization.

, crop residues 

Artificial fertilisers are from non living sources and include most of our man made, petroleum fertilisers and commercial fertilisers

Potassium chloride contains very high amounts of potassium, which can result in an unbalanced phosphate. 

Artificial fertilisers can kill babies or cause health problems in many people because of exposure to synthetic chemical. Also another hazard

synthetic fertilisers can cause a vast array of symptoms, some immediate, some signs showing up later, some affects on people and animals are direct and some effects are indirect. 

Disadvantage of natural fertilisers are slow to break down into the nutrients the growing garden requires. Many natural fertilisers, such as manure, seaweed or fish oil.  ]]> 2019-02-11 05:29:31 UTC https://padlet.com/tallah82_1/jibna8io2y3k/wish/329730215 Natural fertilizers our made through decomposition while artificial fertilizers our made from non living sources and include most of our man made techniques.

- they kills microorganisms and plants: they have high acid content. Acid kills other microorganisms that are beneficial to plants. they bore through and aerate soil. They also deposit rich skin casts. Most importantly, they break down organic matter 
- humans and pets:  
Synthetic fertilizers are not beneficial to you or your pets either. Studies show that exposure to such fertilizers causes cancer in pets. Exposure may also cause respiratory problems in humans.

Synthetic fertilizers produce nutritionally deficient vegetables that do not necessarily give your body the vitamins it needs. In fact, you may consume more pesticides than vitamins.

there are chemicals such as Nitrogen, Phosphorus and Potassium which can be dangerous when combined with fertilizer. there is a natural balance for healthy soil and healthy plants which includes the environment and microbes present. when the synthetic and unnatural force gets unpredictable, it causes problems occur. they can dramatically impact how plants absorb minerals and other necessary elements that help in photosynthesis]]> 2019-02-11 05:34:01 UTC https://padlet.com/tallah82_1/jibna8io2y3k/wish/329730773 fertilizers -marta and adam https://padlet.com/tallah82_1/jibna8io2y3k/wish/329730826 1.

Organic fertilizers have been used for thousands of years making it the oldest known fertilizer. They were used to increase the yield (Crop yield is a measurement of the amount of agricultural production harvested per unit of land area) for plants in the house and also agricultural plants. Organic fertilizers are applied in the soil or sometimes on top of the plant. There is often a variety of nutrients found in organic fertilizers while only having to be applied once. On the other hand, Inorganic Fertilizers are derived from non-living sources and include most of our man made, petroleum fertilizers and commercial fertilizers. Man-made and natural fertilizers contain the same elements but the inorganic/man-made ones react faster than natural fertilizers. Man-made fertilizers when used properly and with right quantities, give the nutrients to the plants efficiently and are also safe for the environment.
