Abstract:
Selected properties of automobile waste and non-automobile waste (control) affected soils and its relation with some heavy metals were investigated in this study. Sampling site was delimited at each area by free survey technique and soil samples collected at the surface (0-20cm) and subsurface (20-40, 40-60cm) depth. Results of the study showed decreased Ca, k, Mg and CEC levels as well as increased Na content of the automobile waste affected soil compared to the control. Both soils were acidic in nature and their heavy metal contents decreased with depth. Higher levels of heavy metals above critical limits in automobile soils using standard were observed .Soil contents of P04-, N03- and sodium adsorption ratio (SAR) were within tolerable limits in both soils. The results indicate that automobile wastes had adverse effect on the nutrient level and fertility status of the studied soil.
