A review on contamination and leaching of nitrate in the ground water

The release of nitrates from lands is a large-scale observable fact. It has now international interest. Maintenance offragile agro-ecosystems in order to reach sustainable agricultural output while caring the environment has involved the interest of scientists and policy makers. Nitrate leaching could be a foremostmenace to environment in diverse agricultural situations. By proper management of agricultural systems, these leaching losses and as well as the nitrate contamination can be reduced and managed. Nitrate pollution of water leads to a number of health risks to human beings and natural world. In the background of the challenge of increasing foodstuff production with decreasing cultivable lands challenging heavy appliance of nitrogen leading to enhanced nitrate leaching. An understanding of the outcome of nitrate in groundwater is essential for managing risks coupled with nitrate pollution, and to protect groundwater supplies and groundwater-dependent surface waters. This review discusses the occurrence of nitrate leaching including the adverse impact and management of nitrate pollution.
