Abstract:Soil organic carbon (SOC) and its different pools are keys to optimizing crop production, minimizing negative environmental impacts, and thus improving soil quality. Investigation of SOC storage and loss are global foci research subject. The research on soil organic carbon sequestration potential in croplands, is an important way to realize a relationship between agricultural processes and ecological processes. Progresse and problems have been reviewed out in this paper. Cultivation and cropping has led to...
