| Abstract: | In this essay, we would like to show that we have made use of one - grade dynamic equation to determine Nitrogen reneralization potention and rate of castanozem and sierozem in Qinghai agricultural area. The result indicates that there is higher Nitrogen supply volume of castanozem than sierozem, and Nitrogen supply intensity is closely ralated to conditions of environment and moisture capacity. |
