[Effects of grazing and mowing on extractable carbon and nitrogen in typical grassland of Inner Mongolia, China.].

Relying on a long term field manipulated grazing experiment of typical grassland in Inner Mongolia, China, we investigated the responses of soil organic carbon, total nitrogen, extractable carbon and nitrogen, and microbial biomass carbon and nitrogen to livestock grazing and grass mo-wing. The results showed that grazing decreased extractable organic carbon by 11.4%-37.
