Improving soil fertility and increasing crop productivity are two important challenges for the large and increasing population of China. The concepts of sustainable agricultural production emphasize the importance of soil organic carbon (SOC) management, which determines a wide range of soil physical, chemical and biological properties (Reeves, 1997). Enhancing SOC storage in croplands not only benefits soil fertility and agricultural productivity, but also is a means of carbon sequestration, and has been put forward as a solution for mitigating climate change and maintaining soil health.
