<p>
The pH of the soil samples in the study area varied widely, with a mean value of 7.95 and 8.44 at surface and sub-surface soils, respectively. The soils were low in organic carbon at surface and sub- surface and decreased with increasing depth. The electrical conductivity of the soil samples varied from 0.14 to 1.18 dSm-1 with mean value of 0.35 dSm-1 at 0-30 cm and at 30 to 60 cm depth it ranged from 0.12 to 0.85 dSm-1 with a mean value of 0.32 dSm-1. Surface soils recorded high cation exchange capacity (CEC) values than the sub-surface soils. The soils were low in organic carbon and deficit in available nutrients such as Zn, Fe, N, P and Mn. Soil N and Fe had a significant positive correlation with organic carbon (OC). Similarly, Soil K and Ca with CEC, Soil Mg with CaCO3 and Soil sulphur with soil pH had recorded significant positive correlation.
