Analysis of Soil Erodibility Factor for Hydrologic Processes in Kereke Watershed, North Central Nigeria

: Soil erodibility factor plays essential role in determining how susceptible soil is to hydrological processes such as detachment and removal by rainfall runoff that could influence erosion sediment entrainment flooding an area. This paper therefore determined the k-value of Kereke watershed with purpose assessing its susceptibility processes. Data was collected on some properties texture, structure, organic matter content, carbon porosity, bulk density, moisture content k-value. The systematic sampling procedure used select thirty-two settlements which served catchment areas for data collection; from samples were analysis. Tables graph present data, percentages depict variations set. Results study shows have high percent sand particles (71.6%), moderate amount clay (15.7%), silt(12.7%), (0.6%), (1.1%), density (1.4 gcm-3 ), porosity (45.2%), (14.0%) low 0.018. area considered be low, soils are moderately erodible. probably accounts intensity channels entrained sediments observed It recommended management practices should encouraged farmers especially planting cover crops, shifting cultivation fallowing system. will allow nutrients gain improved limit capacity good area.
