Agricultural pollution

Agricultural activities are usually associated with the application of excess fertilizers and pesticides that find their ways to water bodies through drainage water or infiltration to groundwater. Fertilizers usually contain considerable amounts of nitrogen and phosphorus that lead to eutrophication. Minute concentrations of pesticides can placehealth at risk. Moreover, agriculture causes the pollution of water resources with coliform bacteria and pathogens that reach the water bodies from the usage and storage of manure.

Intensive agriculture in the form of greenhouses and tunnels became popular during the recent years. This type of agriculture includes application of large amounts of organic and inorganic fertilizers and pesticides that find their way to the water bodies and cause serious pollution.
