Effect of organic matter on sulphate adsorption in some alfisols of Orissa

Prosad Kumar Das, S.K. Sahu, N. Acharyya

Abstract

The effect of organic matter on sulphate adsorption was investigated in four Alfisols of Orissa. There was increase in SO42- adsorption, equilibrium buffering capacity (EBC), maximum buffering capacity (MBC) and decrease in DGo of SO42- adsorption and supply parameter of SO42- (SP) due to removal of organic matter. The increase in SO42- adsorption capacity, EBC, MBC and decrease in SP were remarkably high in Suakati and Badbil soils, small in Sukinda soil and insignificant in Joshipur soil.
