Abstract

Two field trials in an area of 30 feddans of barren saline-sodic soil, were subjected to different leaching water regimes for six months. The soils were prepared for barley and rice cultivation for three succes­sive seasons, 1989-92, in the presence of different rates of organic manure. Soil and irrigation-drainage water samples were periodically ana­lysed. Leaching water (comprising its regime and its quality) is the prin­cipal limiting factor for reclaiming such soil. After 4 years of reclamation, soil salinity as well sodicity decreased from 38.5 to 4.9 dS,m and from 18.5 to 8.87%. Organic manure addition is the most important factor for facilitating chemical reclaiming processes through improving the structure and nutritional status. Barley and rice yields are increased sea­sonally which reflect pre improvement.
