Table 4 Summary of statistics for total SOC, bulk density, and SOC stock in response to soil depth

From: Exclosures backed up with community-based soil and water conservation practices increased soil organic carbon stock and microbial biomass carbon distribution, in the northern highlands of Ethiopia
