Land use conversion can affect natural ecological processes such as surface runoff and erosion. Therefore, it has potential to change soil stability. The study was carried out in Abaji local government of Federal Capital Territory. The objective was to determine the effects of land use conversion on soil properties, soil erodibility and the relationships among soil properties and some erodibility indices. Duplicate topsoil samples were taken by using steel cylinders auger at 60 different sampling points from three different land use types; 20 of them are in farmlands, 20 in rangelands and 20 in forestlands. Soil particle size distribution, loss of ignition and three erodibility indices were determined. Data were analyzed by using Pearson correlation analysis (at 95% significance level), and ANOVA. According to the study results, land use conversion affects some properties of soils significantly. Loss of soils in forests was significant higher than soils in farmlands and rangelands. Soil aggregate stability percentage in rangelands and farmlands were significantly different. The study results showed that there was significant difference between pH of soils in forests and farmlands (p < 0.05). Pearson correlation analysis results showed significant correlations among erodibility.
