Some leaching trials were conducted on sandy loam, loam and loam sand saline soils (ECe9.8-10.9 dS m-1) in farmer's fields with leaching water depths (Dw) applied per unit soil depth (Ds) of 0.0 (Control), 0.5, 1.0, 1.5 and 2.0 (after saturating the soil) to determine water quantum for leaching under uncropped but continuous ponding conditions. It was found that to leach down same fraction of soluble salts, different water quantum would be required for different textured soils. As a thumb rule Dw/Ds ratio of 1 would be enough to leach more than 80% of the salts from sandy loam soil from the upper 30 cm soil, while leaching water depth of 60 cm is required to leach about 90% salts from the same soil depth (Dw/Ds =2). Similarly, for 80% salt leach-down from loam soil, Dw/Ds required would be 1.3, while it amounts to 1.1 for loamy sand soil. It is suggested that leaching curves for different soils under different agroclimatic conditions may be constructed keeping in view some physical soil characteristics. The leaching curves thus constructed may be used as general guidelines to determine water quantum for leaching and also for developing targeted reclamation programmes. The results further accentuate that leaching in conformity with the salt tolerance limits of the crops to be grown may also enhance water productivity of on-farm reclamation operations.
