Description :
A study was carried out to evaluate the impacts of land use change on soil organic carbon (SOC) fractions in the Yanqi Basin, northwest China. Soil samples were collected from 24 profiles in cropland and native land, and labile, semi-labile, and recalcitrant organic carbon were measured. The results highlighted that : All SOC fractions were higher on the cropland than on the native land; The greatest increase was found in the recalcitrant SOC fraction. This study suggests that converting native land to cropland in arid region not only enhances SOC stocks but also leads to longer-term SOC storage.
