Abstract: Background and Objective: Soil extracellular enzymes activities can reflect the metabolic need and nutrient availability of soil and as well possess the propensity to restore polluted soil towards normalcy. This study investigated the ability of some soil extracellular enzymes to recover crude oil polluted agricultural soil. Materials and Methods: Standard potentiometric method of pHKCl determination, loss of weight on ignition and culture methods were employed for all enzymatic and respiratory assays, organic matter and microbiological analyses, respectively. Results: Ninety days after planting, M. alternifolius and F. ferruginea treated soil groups recorded between 8.53 and 673.24% recovery as regards to dehydrogenase, protease, acid and alkaline phosphatase activities. Conclusion: Generally, the enzymes restored the polluted soil towards normalcy, probably necessitated by the treatment plants which aided in the abatement of the pollution and restoration of polluted soil.
