To explore the optimal land-use for soil carbon (C) sequestration in Inner Mongolian grasslands, the AA. investigated C and nitrogen (N) storage in soil and soil fractions in 8 floristically and topographically similar sites which subjected to different land-use types (free-grazing, grazing exclusion, mowing, winter grazing, and reclamation). The results provided evidence that Inner Mongolian grasslands have the capacity to sequester C and N in soil with improved management practices, which were in the order : grazing exclusion > mowing > winter grazing > reclamation
