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 this 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 such as research papers, journals, textbooks, and the internet, and a total of publications/articles/research papers were reviewed. Land-use changes from Forest, pasture land, swamp/ Wetland, shrubland, and rangeland, on the other hand, fell by 19%, 18%, 32%, 7%, and 5%. The physical and chemical qualities of soil were modified by changes in land use change. Physical soil properties such as The BD of farm land was 0.3 g/cm3 higher than that of forest land and 0.2 g/cm3 higher than that of grass land. Highest carbon stock was recorded in agriculture as compared to forestlands changes of SOC (8.99 Mg ha-1) 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 and lower in cultivated land. 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 enclosure land, although sand content (percent), TN (percent) were lower. Forest lands had greater chemical soil qualities such exchangeable calcium (Ca2+), magnesium (Mg2+), and potassium (K+). Organic carbon, available potassium (AVP), total nitrogen (TN), exchangeable calcium (Ca2+), exchangeable magnesium (Mg2+), exchangeable potassium (K+), and exchangeable cation capacity (CEC) were all higher in forest lands than in cultivated lands. In comparison to cultivated and grazed fields, forest land had greater pH, SOC, TN, av. phosphorus, and CEC. 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 practises must be implemented.
