The main causes of agricultural pollution

1, the scientific use of agrochemicals is not strong enough.

The tradition of using large quantities of chemical fertilizers and pesticides to increase crop yields has not fundamentally changed, and after excessive chemical fertilizers and pesticides have been used inefficiently by crops, a large amount of nitrogen and phosphorus nutrients are surplus in the soil and lost to the environment in various forms, leading to serious agricultural pollution problems.

2. Agricultural production and rural household waste.

Agricultural production waste is mainly residual agricultural film and crop residue. The use of plastic film is increasing, and agricultural film pollution has become one of the main sources of farmland pollution. Farmers arbitrarily piled or dumped on both sides of the river, not only occupies a large area of arable land, but also led to the deterioration of the water ecological environment, has jeopardized the rural ecological security.

3, pesticide packaging waste recycling efforts are not enough. Due to the lack of financial support, farmers use pesticides to discard pesticide packaging waste, pollution of farmland.
