Soil organic carbon (SOC) is an important component of the global carbon cycle. Uncertainties remain about the estimation of SOC storage because of a lack of information about temporal SOC accumulation in deep soil layers. Four ages of a Black locust (Robinia pseudoacacia) revegetation chronosequence including 9 (ch9),15 (ch15),24 (ch24) and 34 years (ch34) in the hilly Loess Plateau region was selected for this study. Vegetation characteristics and SOC dynamics down to a depth of 2m were investigated along...
