The use of GMO crop plants engineered for herbicide resistance can also indirectly increase the amount of agricultural pollution associated with herbicide use. For example, the increased use of herbicide in herbicide-resistant corn fields in the mid-western United States is decreasing the amount of milkweeds available for monarch butterfly larvae.
Proper management of pastures, notably managed intensive rotational grazing and grazing at low intensities can lead to less use of fossil fuel energy, increased recapture of carbon dioxide, fewer ammonia emissions into the atmosphere, reduced soil erosion, better air quality, and less water pollution.

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 ...
Water pollution due to dairy farming in the Wairarapa area of New Zealand (photographed in 2003) Agricultural pollution refers to biotic and abiotic byproducts of farming practices that result in contamination or degradation of the environment and surrounding ecosystems, and/or cause injury to humans and their economic interests.
Cover crops can increase microbial activity in the soil, which has a positive effect on nitrogen availability, nitrogen uptake in target crops, and crop yields. Cover crops reduce water pollution risks and remove CO2 from the atmosphere. [1] Cover crops may be an off-season crop planted after harvesting the cash crop.
Greenhouses allow for greater crop production and also use less water since they are closed systems. [84] Desalination techniques can turn salt water into fresh water which allows greater access to water for areas with a limited supply. [85] This allows the irrigation of crops without decreasing natural fresh water sources. [86]
The absence of environmentally friendly agricultural waste management further leads to animal suffering, water pollution, fertilisation, and decline in biodiversity, among others. [ 25 ] According to the waste hierarchy , burning agricultural waste for the sake of energy generation is a less environmentally friendly treatment method than ...
Water conservation: Water conservation is the practice of using less water in agriculture. This can be done by using drip irrigation, planting drought-tolerant crops, and mulching. Sustainable land use: Sustainable land use is the practice of using land in a way that meets the needs of the present without compromising the ability of future ...
