Abstract

                                On an average, soluble CO2 + HCO and Nat constituted 74.2 per cent and 96.8 per cent of total soluble anions and cations respectively and were highly and positively correlated with each other (r = 0.958**), showing the dominance of Na2CO3 in these soils. The amount of various anions and cations followed the sequence as CO2 + HCO3> CI>SO4 2- and Na4> Ca2+ + Mg2+ >K+ respectively. Soil ECe increased by an unit with every 11.6 m.e.L¹ increase in soluble cations. Soluable CO2 + HCO and Na significantly correlated with ECe of soils (r = 0.954** and 0.979) and pHs (r=0.535 and 0.518**) respectively, explaining the major role of these ions in regulating the pHs and ECe of salt affected soils.
