ABSTRACT: The analysis of soil pH level and alkaline phosphate activity in crude oil treated soil following remediation with poultry manure (PM) and sawdust (SD) were studied for four weeks using standard bioremediation techniques. The result showed a statistically significant increase in soil pH level after bioremediation (P>0.05) while the alkaline phosphatase activity in the soil increased upon crude oil contamination from 1.78±014IU/g to 1.89±0.114IU/g. Treatment of crude oil contaminated soil with sawdust reduced alkaline phosphatese activities to (1.65±0.132IU/g on the same day 0 (P>0.05). statistical analysis show that only the sawdust decreased alkaline phosphatase activity significantly (P<0.05 during bioremediation. The results of this study suggest that a combination of poultry manure and sawdust in bioremediation of crude oil contaminated soil is a solution to the menace of oil spillage in Niger Delta areas of Nigeria.
