In order to prevent agricultural pollution, quarantine and extensive research on the organism's potential efficacy and ecological impacts are required prior to introduction. If approved, attempts are made to colonize and disperse the biocontrol agent in appropriate agricultural settings. Continual evaluations on their efficacy are conducted. [13]
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 ...

For example, the means-based analysis might look at pesticides and fertilization methods that farmers are using, and effect-based analysis would consider how much CO 2 is being emitted ...
Eutrophication in a lake caused by nonpoint pollution from agriculture Filter strips are commonly used to prevent eutrophication in surface waters. Eutrophication is a widespread problem in rivers, lakes, estuaries, and coastal oceans, directly caused by the over-enrichment of nitrogen and phosphorus; the source of which is overwhelmingly ...
