Soil Physicochemical properties and enzyme concentration were evaluated in soil from a refined-oil contaminated community in Isiukwuato, Abia State three years after the spill. The soil enzymes examined were urease, lipase, oxidase, alkaline and acid phosphatases. Results show a significant (P soil relative to the control. Soil temperature, Organic Carbon(OC), Organic Matter (OM), Exchangeable Acidity (EA), Saturation Base (SB) and Effective Cation Exchangeable Capacity (ECEC) were significantly higher (p These results suggest that the soil is not yet suitable for agricultural activity.
