| Abstract: | Water resources shortage is a very important factor to obstacle sustainable development of agriculture in the arid and semiarid regions. Many researchers are making their all efforts to search ways to improve soil penetrability. One of the measures is to spread amendments on soil to flocculate fine sediment, increase soil penetrability, and decrease soil and water loss. In this paper, the effects of fine sediment flocculation and deflocculation on soil penetrability, soil erodibility and contaminants transport are discussed, which is helpful to control effectively soil and water loss and ease non source point pollution. |
