The use of biological pest control agents, or using predators, parasitoids, parasites, and pathogens to control agricultural pests, has the potential to reduce agricultural pollution associated with other pest control techniques, such as pesticide use. The merits of introducing non-native biocontrol agents have been widely debated, however.
Agricultural wastewater treatment is a farm management agenda for controlling pollution from confined animal operations and from surface runoff that may be contaminated by chemicals in fertilizer, pesticides, animal slurry, crop residues or irrigation water.
In agriculture, the leaching out of nitrogen compounds from fertilized agricultural lands is a nonpoint source water pollution. [3] Nutrient runoff in storm water from "sheet flow" over an agricultural field or a forest are also examples of non-point source pollution.
In southeast Minnesota, for example, drinking water wells were found to be contaminated with nitrate, which has been linked to some forms of cancer. ... in a bid to reduce agricultural runoff. ...
An example in Tennessee of how soil from fertilized fields can quickly turn into runoff creating a flux of nutrients that flows into a local water body. The principal source(s) of nutrient pollution in an individual watershed depend on the prevailing land uses. The sources may be point sources, nonpoint sources, or both:
For decades, the Salton Sea was the final destination for agricultural runoff, which included toxic pesticides and fertilizer. As the lake has shrunk, more of the lake bed continues to be exposed ...
Runoff of soil and fertilizer on a farm field during a rain storm. Nonpoint source (NPS) water pollution regulations are environmental regulations that restrict or limit water pollution from diffuse or nonpoint effluent sources such as polluted runoff from agricultural areas in a river catchments or wind-borne debris blowing out to sea. In the ...
Topsoil runoff from farm, central Iowa (2011). Water pollution in the United States is a growing problem that became critical in the 19th century with the development of mechanized agriculture, mining, and manufacturing industries—although laws and regulations introduced in the late 20th century have improved water quality in many water bodies.
