Because these processes keep nitrogen concentrations relatively stable in most ecosystems, a large influx of nitrogen from agricultural runoff can cause serious disruption. [19] A common result of this in aquatic ecosystems is eutrophication , which in turn creates hypoxic and anoxic conditions – both of which are deadly and/or damaging to ...
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. Agricultural wastewater treatment is required for continuous confined animal operations ...
The runoff from pesticides and chemicals in the plastic can cause serious deformations and death in shellfish as the runoff carries the chemicals toward the oceans. [66] In addition to the increased runoff that results from plasticulture, there is also the problem of the increased amount of waste from the plastic mulch itself.
A spectrum of opinion exists across agricultural and environmental circles over how to address nutrient runoff — and how much of a role the government should have in moving the needle.
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.

Today, over 3.5 billion kilograms of synthetic pesticides are used for the world's agriculture in an over $45 billion industry. [17] Current lead agrichemical producers include Syngenta (ChemChina), Bayer Crop Science, BASF, Dow AgroSciences, FMC, ADAMA, Nufarm, Corteva, Sumitomo Chemical, UPL, and Huapont Life Sciences.
Nutrient pollution, a form of water pollution, refers to contamination by excessive inputs of nutrients.It is a primary cause of eutrophication of surface waters (lakes, rivers and coastal waters), in which excess nutrients, usually nitrogen or phosphorus, stimulate algal growth. [1]
[1] [2] Together with runoff and leaching, drift is a mechanism for agricultural pollution. [3] Some drift results from contamination of sprayer tanks. [4] Farmers struggle to minimize pesticide drift and remain productive. [5] Research continues on developing pesticides that are more selective, [6] but the current pesticides have been highly ...
