Four replicates of soil samples were collected in each L.G.A. at depths of 0 to 30 cm using soil auger. These soil samples were used for the determination of soil texture, soil pH, organic C, total N, C/N ratio, available P, exchangeable K and cation exchange capacity. Data collected were analysed using standard error and coefficient of variance. Results of the study showed that the soils of the three L.G.As were sandy loam. The pH of soils studied were all strongly acidic, and the order of the increase is Ivo=Ohaozara<Onicha. The lowest organic C value of 1.26% recorded at Onicha was lower than that of Ivo and Ohaozara by 15% and 61% respectively. The order of increase in total N and C/N ratio is Ohaozara >Ivo>Onicha. Onicha recorded the highest available phosphorus value of 16.65mgkg-1 whereas the lowest available P value of 13.58mgkg-1 was observed at Ivo. Apart from Onicha which recorded 0.31 Cmol(+)kg-1 value of exchangeable K, the values of exchangeable K observed in the other two L.G.As. were below 0.20 Cmol(+)kg-1 regarded as the critical limit of exchangeable K in soils. The highest CEC value of 7.90 Cmol(+)kg-1 recorded in Onicha was higher than that of Ivo and Ohaozara by 29% and 17% respectively. These soils were strongly acidic and low in plant nutrient, therefore, the application of lime, organic and inorganic fertilizers is indispensable for optimum crop performance in them. Key Words: Chemical properties, fertilizer, infertility and productivity.
