Abstract：Under experiment of long term,fixed position N application nitrogen balance,capacity of N reservoir in soil,amount of NH 3 volatilization and NO 3 N leaching and intensity of N cycle were investigated. By calculating sum total of profit and deficit to determine intensity of N balance,the maximum N balance intensity was 269.6%{A 1B 1},the minimum was 49.4%{A 3B 3},average was 162.5%. There was significant corre llation between amount of profit and deficit of N and capasity of N reservoir{r=0.659...
