Abstract

An electrical Wenner-alpha and Schlumberger survey was carried out to select the viable regions for agricultural activities and to determine the most suitable regions for siting boreholes. The results of the Wenner-alpha data show the study area is highly conductive ranging from 1.1 mS/m to 9.8 mS/m, reflecting the soil water content of the terrain. Consequently, the soil water content of the terrain shows that the terrain is good enough for any agricultural activities operating within the limit of 0 - 4 m depth topsoil, based on the soil electrical conductivity survey data. Similarly, the results of the Schlumberger show that; 72% of the terrain is covered by deeper aquifers where the basement rock is weathered and fractured, while the shallow aquifer regions cover only 28% of the terrain.
