| Abstract: | Reviewing and summarizing the related research of farmland soil nitrogen leaching loss is a crucial basis of studying agricultural non-point source of nitrogen pollution. This paper introduced and analyzed the leaching form and migration mechanism of soil nitrogen, research methods and influencing factors of nitrogen leaching in farmland soil. The recent research progress of nitrogen leaching in farmland soil at home and abroad was summarized, and the future research priorities were pointed out. The research conclusions have some reference values on farmland soil fertilization management measures and slowing down the nitrate nitrogen pollution in shallow groundwater. |
