Effect of Soil Management Practices on Runoff and Infiltration Processes of Hardsetting Alfisol in Semi-Arid TropicsK P CRaoauthorA LCogleauthorS TSrinivasanauthorD FYuleauthorG DSmithauthorAlfisols oi Semi-Arid Tropics (SAT) are often chiiractcriscd as structurally unstable (EL-Swaify et 31.. 1905). Under the impact of raindrops the structural instability leads to formation of a seal on the surface. The surface seals rcducc infiltration and increase runoff (Moore, 1981 1. As a result, plant-available water in the profile gets reduced. In most of the SAT Alfisols crop yields arc constrained by the plant-available water.Soil Science1994Conference or Workshop Item
