The study was conducted to evaluate the current soil fertility status of different farmlands in Yagba West Local Government area of Kogi state. A total of 24 samples were taken from two districts at a depth of 0-15cm and 15-30cm from each ward. The samples were analyzed each for their Physio-chemical properties. The results obtained showed that particle size distribution ranged from loamy sand (LS) to sandy loam (SL). The pH of the area were within 5.0-6.54, a pH range suitable for most agricultural crops, while EC of the soils ranges from 0.10-0.60µmhos/cm. Available phosphorus (P) in the soil ranged from 2.26-20.42mg/kg with a mean value of 8.02mg/kg at depth of 0.15cm and 1.23-14.2mg/kg with a mean value of 5.66mg/kg at depth of 15-30cm, which is below the critical value of 15ppm. Total nitrogen and organic carbon fell below their critical values of 0.78% and 0.64% respectively. Exchangeable cations (Ca, Mg, K, Na) gave mean values of 3.21, 1.14, 1.38 and 0.64Cmol/kg respectively of Ca, Mg, K and Na. Exchangeable acidity has a mean value of 1.0(Cmol/kg) a condition that indicated moderate acidity, meaning that the soil should be properly managed for optimum productivity, with percentage base saturation of 86.91 (mol/kg) mean value.
