Currently more than 20 per cent of the world’s irrigated land is salt affected. Of that about 60 per cent are sodic soils, warranting attention for efficient, inexpensive and environmentally feasible amelioration. An incubation study was performed to study the influence of amendments on physico-chemical and biological properties of sodic soil. Gypsum + Green manure @ 6.5 t ha-1, Distillery spentwash (DSW)@ 5 lakhs liter-1, Green leaf manure (GLM) @ 12.5 t ha-1were used as amendments for the reclamation of sodic soil by adopting standardized reclamation procedure. The results of the incubation study revealed that application of amendments decreased the pH of the soil. The pH declined from the initial level of 10.2 to 8.37, 8.42 and 9.21due to application of DSW, Gypsum + GM, and GLM respectively. Maximum reduction in soil pH was recorded in DSW applied treatments. The soluble salt concentration was found to be slightly increased in the DSW applied treatments, but the extent of increase was within the permissible limit (Gypsum + GM>GLM>control.
