Characterisation of grey water and its influence on some basic soil properties

Abstract

A experiments were conducted to examine the effects of greywater irrigation on changes in soil properties. The different proportions of grey water and ground water were used as experimental treatments. Surface soil samples (0-15) were analyzed for physical and chemical properties, viz., bulk density, porosity, pH, EC, organic carbon (OC), in soil. The pH and EC values of the greywater used in the study were 8.80 and 0.96 dSm-1 respectively. Results show that greywater irrigation had no significant effect on soil organic carbon. However, pH, EC and organic carbon was highest in treatment receiving 100% grey water. Bulk density of soil was increased while pore space of the soil were decreased with application of grey water.
