Abstract The decomposition of soil organic carbon (SOC) plays a critical role in regulating atmospheric CO2 concentrations and climate dynamics. However, the mechanisms and factors controlling SOC decomposition are still not
fully understood. Here, we conducted a 60 days incubation experiment to test the effects of physical disturbance
and nitrogen (N) addition on SOC decomposition. N addition increased the concentration of NO3- by 51% in the
soil, but had little effect on the concentration of NH4+. N addition inhibited SOC decomposition, but such an
effect differed between disturbed and undisturbed soils. In disturbed and undisturbed soils, application of… More >
