The fertilizer experimental site used in this study was established on a maize field in Shenyang Agriculture University in 1987. The treatments included, CK : unfertlized control, M : organic manure, N : inorganic N fertilizer and MN : combination
increase in degree of grain yield to the N and MN treatments, therefore it could be the best option for improving soil productivity and C storage in the maize cropping system.
