Filter strips are primarily used in agriculture to control nonpoint source pollution. They function by decreasing the velocity of water, allowing runoff and dissolved inorganic molecules to infiltrate the soil. [8] Vegetation then uptakes these inorganic molecules, notably nitrogen and phosphorus, reducing their concentrations in nearby surface ...
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 ...
Agricultural runoff is a major source of nitrogen and phosphorus, which contribute to freshwater acidification. Implementing best management practices (BMPs) in agriculture, such as reducing the use of chemical fertilizers, improving manure management, and adopting precision agriculture techniques, can significantly reduce nutrient runoff into ...
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 ...
Contour buffer strips used to retain soil and reduce erosion. A buffer strip is an area of land maintained in permanent vegetation that helps to control air quality, soil quality, and water quality, along with other environmental problems, dealing primarily on land that is used in agriculture.
The EPA established the hypoxia task force in the late 1990s to reduce nutrient pollution and shrink the dead zone, but it relies on voluntary efforts to reduce farm runoff and hasn't ...
Contour strip cropping employs a crop rotation system down a slope to minimize runoff and rain velocity. [1] It is used mainly on gentle slope gradients. The width of protective strips is often higher than that of the row crop strips, so they may effectively intercept runoff.
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.
