Discusses the latest information regarding the processes and mechanisms responsible for runoff and erosion by water in arable lands--detailing state-of-the-art water and soil conservation methods. Elucidates the rehabilitation of agricultural lands depleted by human activity.
Part 1 Soil erosion by water: basic factors and processes in soil erosion - infiltration and seal formation processes, rainfall analysis, soil characteristics and aggregate stability, splash and detachment by waterdrops, slope, aspect and surface storage, the effect of surface cover on infiltration and soil erosion; forms of erosion - interill erosion, rill and gullies erosion; soil loss and runoff estimation - soil loss estimation, runoff estimation in agricultural fields. Part 2 Soil conservation: common soil and water conservation practices; soil stabilizers. Part 3 Soil rehabilitation: reclamation of gullies and channel erosion; reclamation of salt affected soil; reclamation of sodic affected soils; impact of crop rotation and land management on soil erosion and rehabilitation.
