Abstract：Agricultural non-point source pollution has become an important part of environmental pollution in our country,and posing a major threat to agricultural production and ecological environment security.Nitrogen losses by surface runoff and leach from croplands have been one of the major sources of the agricultural non-point source pollution.Nitrogen was a critical limiting nutrient that increases vegetable production.The pursuit of economic efficiency,excessive nitrogen fertilizer caused nitrogen pollution becomes worse and worse.In this paper,the research status of transfer and transformation of soil nitrogen were summarized.We also discussed the processes of soil nitrogen transfer and transformation,including fertilization,runoff,leaching,NH3 volatilization and so on.The process of mineralization,nitrification and denitrification in soil was analyzed.The research direction in the future was prospected.
