Information on the effects of various land-use types on selected soil properties is critical for the sustainable use of soil resources. As a result, this study was carried out to assess the variation of soil properties attributable to land-use types and soil depth of the western highland of Oromia. A total of 45 composite soil samples were collected from forest, grass, eucalyptus plantation, cultivate and grazing lands using three soil depths and three replications. ANOVA was used to test the mean differences in soil properties. Sand and clay mean values were highest in grazing and forest, respectively. The mean bulk density of the soils ranged between 1.10 and 1.61gcm-3, and the mean total porosity ranged between 39.37 and 58.49%, indicating lower soil compaction. The mean pH ranged from 4.92 to 5.55, with mean OM values ranging from 0.64 to 5.91% while the mean values of total N ranged from 0.04 to 0.31%. The mean value of available P ranged from 2.10 to 7.26mg kg-1. Conversion of land use types harms soil properties, particularly overgrazing, eucalyptus plantation and cultivation of deforested land. Therefore, the deteriorated soil's physical and chemicals should be amended with different soil water conservation measures.
