Abstract:

The comparative effects of Abelmoschus esculentus and Corchorus olitorius on soil contaminated with mixture of petroleum products were evaluated in this study. The pH, moisture, organic matter, microbial population and total petroleum hydrocarbon of the soils at the beginning and the end of the study were evaluated. Growth of A. esculentus led to loss of more TPH from the soil than the growth of C. olitorius. The growth of A. esculentus increased soil alkalinity and the soil moisture content more than that of C. olitorius. More bacteria and fungi were isolated from soil that had A. esculentus than from soil that had C. olitorius. Significant differences were noticed between the impacts of A. esculentus and that of C. olitorius on the soil contaminated with mixture of petroleum (p<0.05, p<0.01, p<0.001). The findings in this study show that A. esculentus has better ability to remediate petroleum contaminated soils than C. olitorius. Since both crops are easily propagated and readily grow in most soils, they can be very useful in combating the problems associated with contamination of soil with petroleum products.
