A study conducted in Melka Gura Subwatershed to assess soil properties across three types of land uses plantation forest, grazing land, and cultivated land from 2022 to 2023 found that all land uses had loam soil, except for the plantation forest, which had sandy loam. The mean soil BD in the study area ranged from 1.06 to 1.39 g/cm3. Conversely, plantation forest soil and grazing land had the highest mean AWC (194.8 mm/m) at 0–20 cm depth. The highest mean values of sand, silt, TP, pH, AP, exchangeable basic cations, CEC, SOC, TN, and SOC stock (68.62-ton ha-1) were registered in the soil of plantation forest land. The highest mean values of BD (1.39 g/cm3), clay content (19%), Ex. A, and Ex. Al were recorded in the soil of cultivated land. The average values of clay, BD, FC, PWP, pH, PBS, and exchangeable bases all indicated an increasing trend from the surface toward the subsurface. The highest mean value of SOCS (68.62 tons’ ha-1) was discovered in plantation forest land and the lowest in cultivated land. The differences in soil management practices could be the major reasons for variations in soil properties across land-use types. Further studies are needed on the effects of land-use change on fertility-related soil properties in relation to integrated soil and water conservation practices to reduce further land degradation.
