Abstract

One of the major causes of soil quality degradation and carbon stock degradation is land-use changes (LUC), which are predominantly caused by deforestation and soil disturbance. Thus, the objective of the present study was to assess how land-use changes impacted soil properties, soil organic carbon stock and quality in Ethiopia. Relevant information was gathered from secondary sources and systematically reviewed. The physical and chemical qualities of soil were modified by changes in land use change. Physical soil properties such as bulk density (0.3g/cm³) was found to be higher in cultivated land and BD (0.2g/cm³) lowest in the forest lands. The forest lands (8%) have recorded higher soil organic carbon content than grassing land (5.16%) and cultivated land (2.31%). The moisture content and soil texture altered according to land-use change, with clay contents (percent) and silt contents (percent) being higher in forest land (60.7, 5.74%) and lower in cultivated land (33.8, 5.74%). Chemical soil qualities such as exchangeable CEC (percent), CaCO₃ (percent), exchangeable K and Na+ (Cmol/kg), and AV. P (mg/kg) were higher in forest land (16mg/kg) lower in grass land (14.27 mg/kg) land and cultivated land (9.13 mg/kg) and TN were higher in forest land (0.24mg/kg) lower in cultivated land (0.14 mg/kg). CEC were higher in forest land (25.5 cmo/kg) and grazing land (24.02 cmol/kg) and lower in agricultural land (15.5cmol/kg). Chemical soil qualities such as exchangeable calcium (Ca²⁺), magnesium (Mg²⁺), and potassium (K⁺). Organic carbon, exchangeable potassium (K⁺), and exchangeable cation capacity (CEC) were all higher in forest lands and lowest in cultivated lands. The highest soil SOCst (9.99 Mg ha^-1) value was recorded in forest-to-forest land use changes, and low value of SOCst (5.78 Mg ha^-1) was obtained in agriculture land. The lowest SOCst value was in land use changes from agriculture to agriculture. To save Ethiopia's soil, workable land use policy has to be developed. In addition, restoration methods, such as reducing the intensity of cultivation, integrated soil water conservation, integrated soil fertility management, and adequate land use management practices must be implemented.
