Review of Soil Carbon Sequestration of Cropland

Soil organic matter plays a key role in soil feitilization,plant nutrition,soil quality and tillage.Thus,it is a research hotspot in relation to the mechanism of carbon cycle and balance in soil.Substantial evidence showed that proper soil management should be conducted to adjust organic matter accumulation and decomposition.At the same time,soil carbon cycle had a big effect on environment.It is essential to increase soil carbon storage.In this paper,we reviewed the advances with respect to carbon stocks,and effective measures for increasing organic carbon content in terrestrial ecosystem.
