The impact of hydrocarbon industrial wastes on soil physico-chemical, biological and enzyme properties was assessed in the present study. Contamination of soil with hydrocarbon industrial wastes cause the changes in physico-chemical, biological and enzymatic properties but undetectable towards soil water holding capacity, sand, Potassium and organic carbon. Soil enzymes such as protease and cellulase enzyme activities were higher whereas dehydrogenase enzyme activity is lower in test than control.With increasing the soil incubation period, soil protease and cellulase activities were increased whereas dehydrogenase activity was ceased in polluted soil in comparisons to control. Higher bacterial and fungal population was observed in the contaminated soil than control.
