Abstract: Soil organic carbon in cultivated land is an important component of farmland soil carbon pool. Because of wide distribution and high soil heterogeneity of the cultivated land in China, the land use patterns and planting systems are complex and diverse. It is particularly important for China to study the changes of organic carbon and its storage in cultivated land, to figure out the carbon sequestration capacity of cultivated land, and to understand the coupling mechanism between carbon sequestration and productivity maintenance of cultivated land. A number of Chinese scholars use the data of the second national soil survey and the data reported in the literature to carry out relevant research, but generally speaking, systematic and long-term observational and experimental data of cultivated land soil are relatively scarce. This dataset calculates the topsoil organic carbon density of ecological stations covering main agricultural ecosystems in China from 2005 to 2015 based on the estimation model of organic carbon as well as the measured data of physical and chemical properties of topsoil from 19 China Ecosystem Research Network (CERN) agricultural stations. It can serve as the basis for estimating more accurately the soil organic carbon storage and studying its spatial distribution characteristics of farmland in China.
