4) Use of pesticides, insecticides, and fungicides
1) With monoculture, growing the same one crop year after year depletes the soil of nutrients
2) Synthetic fertilizers disturb the soil and water. Fertilizers only feed the plants, not the soil! When it rains, runoff of the soil can contaminate other water sources
3) Intense tilling of the land can lead to soil compaction and soil erosion, depending on the wetness of the soil when the farmer tills. Compaction causes the soil to not absorb water well, leading to smaller yields. Erosion of the topsoil (wind) can turn into runoff and wash into local waterways, which can contain contaminants. Flooding erosion can also happen, since soil cannot absorb the water.
4) Pesticides impact depends on how the farmer uses them, the soil can either successfully break them down, or they can accumulate in the soil if used too much. It can decrease microbial biodiversity in the soil. Fumigants have been shown to kill nearly all soil organisms.
1) Avoid using pesticides and fertilizers! If you manage your soil correctly using the following methods, you should be okay without fertilizers. Find organic ways to control pests/insects! Use Neem Oil, vegetable oil, or soap spray for example.
2) Rotate crops! Do more rotating than the typical industrial agricultural way we do now, between just corn and soybeans. Plant more varieties of crops to help the soil keep its nutrients.
3) If farmers have cows on their farm, they should use the manure that their own cows produce there. It's silly to find manure elsewhere when you have your own supply. (Green Manure)
