Abstract

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 of organic manure and inorganic N fertilizer. TOC concentration and C storage were significantly increased under the M and MN treatments, but not under the inorganic N treatment. The M treatment was most effective for sequestrating SOC and showed similar 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
