EFFECT OF COIR PITH AS AN AMENDMENT FOR TANNERY POLLUTED SOILS

Abstract

The letting in of tannery effluent causes pollution of ground water and degradation of cultivable land. Soil amendments viz., composted coir pith, pressmud, gypsum and farm yard manure were tried for increasing the productivity of polluted land. Application of 10 Uha of composted coir pith gave increased yield of maize (Co.1) and finger millet (Co.13). The increased yield was due to improved physical condition and keeping the soil moist preventing capillary rise of salts to the surface.
