ABSTRACT: The study examined the impacts of crude oil exploitation on the soil environment of Ogoni region and also identified action plans for the future management of the region. Composite soil samples were collected at two depths: 0 - 15 cm (surface soils) and 15 - 30 cm (subsurface soils) along different positions of landscape in the four study locations. Samples were analysed in the laboratory within 5 days of collection. ANOVA was used to confirm that both soil chemical and physical properties significantly vary in the study locations. The result revealed that sand, silt and clay contents significantly vary in Eleme, Tai, Khana and Gokhana as evident in the calculated F-ratios of 307.70; 606.72; 1312.31; and 1154.02 respectively. This is against the tabulated F-ratio of 3.35 as reflected by the wide variations in sand, silt and clay fractions, and probably owing to differences in parent material. Based on the locations where the soils were sampled, the results indicate that the soils vary widely in chemical characteristics in Eleme (F-ratio = 1674.16; p
