OnuohaEkeoma 12020121Background and Objective: If plants are to grow to their potential, the soil must provide a satisfactory environment for plant growth. Soil pollution with hydrocarbon affects soil aesthetics, biomass, fertility crop yields and threatens food security. This study, therefore, investigates the effect of organo-mineral and liquid fertilizers in the remediation of spent engine oil-polluted soil. Materials and Methods: Soil Sample was polluted at a 10% concentration level with spent engine oil and treated with LF (Liquid fertilizer), OMF (Organo-mineral fertilizer) and a combination LOMF (Liquid organo-mineral Fertilizer). The Total Petroleum Hydrocarbon and five selected heavy metals concentrations of the soil were monitored for 20 weeks. Results: It was observed that the soil treated with LOMF had the highest net removal of total petroleum hydrocarbons (TPH) 89.94 %, this was followed by LF 86.17% and then OMF 84.89 %. The control treatment (F0) had the lowest TPH reduction (56.52%). There were significant differences at (p<0.01) between the treatment fertilizers (F0, LF, OMF and LOMF). Conclusion: This study has demonstrated Organo-mineral and liquid fertilizers effectively reduced the total petroleum hydrocarbon as well as influence the reduction of heavy metals in the soil.]]>Okonokhua, B.O., B.
