The Impacts of Solid Wastes on Soil Characteristics of Selected Dump Sites in Okigwe

Abstract

This study investigated the impacts of solid wastes on soil characteristics in selected dump sites within Okigwe metropolis, Imo State, Nigeria.  The aim of this study was to assess the impacts of solid wastes on soil characteristics in selected dump sites. Experimental research design was used which comprised of two dump sites (A and B) and a control point. It emphasized on the extent to which soil characteristics affects the chemical and physical properties of the soil. The samples were subjected to laboratory analysis to evaluate soil quality indices such as temperature, Moisture Content, Soil Organic Carbon, Soil Organic Matter, pH, phosphorus, nitrogen, potassium.  The result showed changes in the soil properties due to contamination from the waste types sampled. These alterations have health implications for soil health, agricultural productivity and environmental sustainability. The physical parameters differed significantly between the control and the dump sites where the dump sites exhibited darker colours, higher moisture contents, elevated level of organic carbon and a loamy texture, in contrast to the control which was lighter in colour and sandy. The result showed that there was increase of NPK from dump sites A and B compared to the control, which can be as a result of agricultural runoff, detergent, fertilizer and sewage. The study therefore recommended the urgent need for improved waste management practices which will help enhance soil quality and pubic heath in that region.
