Abstract

Organic amendments might be effective and sustainable in the amelioration of saline soil if proper management put in place. Accordingly, subsequent pot and field experiments were conducted in a saline soil to determine the effects of moisture levels and organic amendments on cation exchange capacity (CEC), ion dynamics under rice cultivation. The increment of CEC of the studied post harvest soils was significant, except for the moist condition under field experiment. There were significant variations in ion dynamics among the treatments under both the experiments at saturated soil conditions. Exchangeable Na+ contents decreased and K+ contents increased significantly with the increased rates of treatments. Exchangeable Ca2+ and Mg2+ contents of soil followed almost the similar trends as that exhibited by K+ but not significant. Among the anions, chloride decreased significantly under both the experiments while sulfate and bicarbonate contents increased by the applied treatments. This might be due to the inherent consequences of organic amendments on these soil properties.
