Agriculture can be at the same time diffuse source of pollution, but also a point source of soil and water pollution. However, it is primary considered as diffuse source of pollution. These sources of pollution are most often associated with the discharge of wastewater in cities and residential areas. When it comes to agriculture, pollution of subterranean water happens under the influence of excessive and unprofessional usage of nitrogen and phosphoric fertilizers, pesticides and heavy metals. Agriculture as a point source of pollution is referred to the discharge of wastewater from livestock farms and the discharge of liquid fertilizers in the natural and artificial watercourses. Studies are conducted in Biđ-Bosut field, which covers the 7.200 ha area. Researchers in this work acquired results in ten years of studies between 2000- 2009 and in a five year research period from 2009 until 2013. Agriculture production was monitored on family farms, and the water quality was determined by continuous monitoring of open watercourses lysimeters and hydropedological piezometers. By monitoring the quality of surface water, subterranean water and leachate, over a ten year period, in the study area Pilot, it was determined low pollution with heavy metals, but also high pollution of surface and subterranean waters of Biđ with nitrogen from ammonia, and the presence of high concentration of phosphorus in leachate and surface waters. Dates from five years of researching show that the pollution in surface waters in main watercourses is mainly caused by ammonia and phosphorus. They also show high concentrations of nitrogen and phosphorus in leachate, as well as increased concentrations of nitrogen in subterranean water, where they correspond to the third category of ecological quality. The results of years of research indicate ″risk″ of significant water pollution by nitrogen and other chemicals as a result of agriculture production."
