Abstract
This experiment was conducted in Soil and Water Testing Laboratory of Mono Project during 1987-88. Silty clay loam saline-sodic soil of which gypsum requirement was 10.5 meteric tons/acre ft. was filled in PVC lysimeters of 6.6 cm diameter and 60 cm long. Soil was packed by means of a specially designed wooden cube. The required quantity of different mesh sized gypsum as per 100% of gypsum requirement was added to the upper 15 cm of the soil in the column. The reclamation process was very slow as it took 6 to 8 months for reclamation of the 45 cm soil column where gvpsum was used but this process was much more slow where simple leaching with good quality water was done. Gypsum 60-80 mesh and gvpsum powder were comparatively faster in their effect on reclamation as compared with other gypsum grades but the differences were statistically insignificant. Effect of different grades of gypsum was significant in reducing the EC and SAR of soil. Gypsum with 60-80 mesh size and gvpsum supplied from Ouaidabad crusher were more efficient for the
