AbstractSoil chemical and biochemical properties are important indicators in assessing soil quality. To investigate the effect of manure application on eroded Mollisols, soil organic carbon (SOC), total nitrogen (TN), C/N ratio, and potentially mineralizable nitrogen (PMN), microbial biomass carbon (MBC), urease activity, and sucrase activity were determined aft er 8-yr application of cattle manure in combination with chemical fertilizers in a soil erosion simulation facility by removing the topsoil by 0, 5, 10, 20, and 30 cm in a typical Mollisols region in China. All parameters except C/N ratio showed a declining trend with the increasing of erosion depth. Soil organic C, TN, PMN, MBC, urease activity, and sucrase activity were 11 to 23, 5 to 9, 5 to 16, 11 to 19, 18 to 32 and 13 to 37% higher under the chemical fertilizer + manure treatment than the chemical fertilizer alone plots, respectively. The C/N ratios did not change significantly with the increase of erosion depth, but they were also 5 to 17% higher in the chemical fertilizer + manure treatment than that in the chemical fertilizer alone treatment. Eight-year application of cattle manure in combination with chemical fertilizers improved soil quality of eroded Mollisols, but was not good enough to restore the fertility of eroded Mollisols to that of non-eroded soils.
