Abstract

Soil quality analysis for irrigation in river Katsina-Ala catchment areas of Benue State, North-central, Nigeria was carried out in this research. Several soil samples from three selected catchment areas namely, Logo, Ambighir and Katsina-Ala of Benue state, were collected and analyzed. The investigation was carried out in the wet and dry seasons 2013. The mechanical analysis of the soils indicated that Logo had sandy loam texture while Ambighir and Katsina-Ala were of loamy sand to sandy loam textures. The soils had high values of infiltration capacities (0.0096cm/s to 0.053cm/s). They showed moderate values of CEC (3.09Cmol/kg to 8.50Cmol/kg) and high base saturation (91 to 97%). The pH of the soils varied from slightly acidic in the wet seasons to slightly alkaline in the dry seasons (5.3 to 7.8). Risk of infiltration was envisaged as a result of very low values of conductivity (0.04ds/m – 0.25ds/m). At the present time, infiltration problem is minimal because of high proportion of sand (68% - 89%) in the soils but this situation may not be sustained for long. A regression model (R = 0.773) was obtained which showed that the rate of infiltration strongly depended on the sand content of soil. The soil qualities were found to be suitable for irrigation as the values of the parameters fell within the ‘tolerable’ limits.
