Influences of soil properties and hydrological processes on soil carbon dynamics in the cropland of North China Plain

Recent studies showed great variations in both soil inorganic carbon (SIC) and organic carbon (SOC) in cropland across the North China Plain. This work was designed to test the hypothesis that hydrological processes associated with the Yellow River may be responsible for the differences in soil carbon dynamics over space. We selected 22 sites from the wheat-maize cropland across the Yellow River in the south North China Plain, and measured SOC,...
