Abstract

The important source and cause of agricultural pollution are Irrigational return flows, and use of nitrogenous fertilizers in which nitrate is the basic component. High concentrations of Nitrate in groundwater may cause methemoglobinemia, and have been cited as a risk factor in developing gastric an intestinal cancer. One of the most important negative effect of intensive use of nitrogenous fertilizer use is water eutrophication. Nitrates in the irrigational water serves as a nutrient to plants and crops. Ayers and Westcot, (1994) mention that nitrate in excess to 30 ppm causes severe problem in sensitive crops. Due to the impact of fertilizers on human and environment, it is quite necessary to reduce the nitrate concentrations to safe levels.

Keywords: Nitrogenous fertilizers ; Groundwater ;SOURCE OF NITROGEN AND NITRATE.
