How Fertilisers can be harmful to crops

The main scourges of slash-and-burn are habitat destruction, erosion, smoke, rapidly falling productivity, and increasing pests in short-fallow systems. Slash-and-burn farming, where trees are cut and vegetation burned for crops, seems quick but harms in many ways. Soil loses nutrients fast, forests are destroyed, biodiversity drops, soil washes away, climate change worsens, and fights over land can happen. It's a tempting but damaging practice that hurts farming and the environment in the long run.

How Fertilisers can be harmful to plants

Chance of over fertilisation if used wrongly. This can not only kill the plants but upset the entire ecosystem. Chemical fertilisers tend to leach or filter away from the plants, requiring additional applications.

How Fertilisers can be harmful to plants (Part 2)

2gb6xjhgxg — 2024-05-02 00:15:54 UTC

Fertilizers are not really harmful to plants, but when overuse, it can cause the soil of the plants to be hardened.

Some of these impacts include algae blooms causing the depletion of oxygen in surface waters, pathogens and nitrates in drinking water, and the emission of odors and gases into the air. Nutrients from manure and fertilizers enter lakes and streams through runoff and soil erosion.

how it can be useful to crops production

du_sichen — 2024-05-02 00:20:57 UTC

Slash and burn agriculture is a widely used method of growing food in which wild or forested land is clear cut and any remaining vegetation burned. The resulting layer of ash provides the newly-cleared land with a nutrient-rich layer to help fertilize crops.

What is flash and burn method?

2024-05-02 00:23:29 UTC

Slash and burn is a method of farming that involves clearing land by destroying and burning all the trees and plants on it, farming there for a short time, and then moving on to clear a new piece of land. Traditional slash and burn farming methods have exhausted the soil.

how to photosynthesis crop the production

2024-05-02 00:24:24 UTC

Photosynthesis is a fundamental process that produces oxygen, regulates the climate, and stimulates physiological processes such as crop yields

how do fertilizers help in crop production ?

2024-05-02 00:27:19 UTC

Fertilizers help by providing appropriate nutrients to ensure the healthy growth of plants , thus increasing the yield . And also without fertilizers , nature will struggle to replenish the nutrients in the soil .

what makes photosynthesis

2024-05-02 00:28:09 UTC

Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

Pesticide and herbicides can be harmful because they contain chemicals that can be toxic to humans, animals, and the environment. These chemicals can contaminate water sources, harm beneficial insects, and have long-term effects on ecosystems. It's important to use them responsibly and consider alternative methods when possible.

what is the purpose of slash and burn

2024-05-02 00:30:53 UTC

Slash-and-burn involves removing and drying out vegetation (slash), followed by burning to create a nutrient-rich ash layer in which crops can be grown. Slash-and-burn is unsustainable when practiced in areas of high population density, particularly in environmentally fragile areas like steep slop

why are fertilizers important in crop production ?

2024-05-02 00:49:08 UTC

Fertilizers help the soil increase its fertility thereby promoting growth . The use of manures as compost is presumably as old as agriculture itself . With the help of fertilizers , plants become resilient against harmful plant pathogens , pests and weeds .

Slash-and-burn agriculture is a farming method that involves the cutting and burning of plants in a forest or woodland to create a field called a swidden. The method begins by cutting down the trees and woody plants in an area. The downed vegetation, or "slash", is then left to dry, usually right before the rainiest part of the year. Then, the biomass is burned, resulting in a nutrient-rich layer of ash which makes the soil fertile, as well as temporarily eliminating weed and pest species.
