Drivers of soil carbon and nitrogen stock in topsoil and deep soil under grazing in two steppe ecosystems
Published 2025-08-01“…In this study, we investigated the effects of grazing and steppe type on the SOC and TN concentrations, stocks, enzyme activities, and microbes in the top 1-meter soil layer of semi-arid steppe in Inner Mongolia. The results showed that grazing significantly reduced SOC and TN stocks in the 0–30 cm soil layer of the meadow steppe but significantly increased SOC and TN stocks in the 70–100 cm soil layer of both meadow and typical steppes. …”
