| 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. | ||||
