Influence of Sequential Washing on The Ph and Electrical Conductivity of Graded Coir Pith

Coir pith is being considered as a waste generated during the separation of fibres from the husk. It is a light weight spongy material, and has lignin, cellulose, hemicelluloce and protein in substantial amount. In the present study, the pH and electrical conductivity (EC) were analyzed in the sieved coir pith during sequential washing. The results indicated that the hydrogen ion concentration was low in unwashed and first washed coir pith and high in final wash and simultaneously EC was high in unwashed and low in seventh washed coir pith extract. The final washed coir pith could be taken to future studies, because a suitable pH and EC had been achieved in the final wash. The results suggest that, pH and EC are the major influencing factors that determine the quality of any soilless media and the ways to bring them to an optimum level.
