Organic Matter and Salt Concentration Effect on Cation Exchange Equilibria in Non-calcareous Soils
Imrana Naseem and Haq Nawaz Bhatti

Abstract: Studies were conducted to investigate the effect of organic matter arid salt concentration on cation exchange equilibria In non-calcareous soils. Various physico-chemical properties like pHs, ECe, soluble ions, exchangeable cations, ESP, SAFI, lime and organic matter were determined. In homovalent (K+-Na+) exchange, the values of Kk increased with increasing organic matter. The results of three levels of salt concentration indicated that equal concentration of both the salts showed less coefficient values es compared to 1:2 K+-Na+ concentration, but this coefficient values markedly increased by 2:1 K+-Na+ concentration. In heterovalent (K+-Ca2+) exchange, selectivity coefficients showed an increase with increasing organic matter, while in case of salt concentration, 2:1 ratio had marked effect on Kk, Ky and KG values.
