  Increasing of population in the world caused overusing natural resources and land destruction. Salinization and sodification are two effects of land destruction especially in dry and semi-dry areas. Leaching of soil soluble salts in soil profile could be one of the most appropriate method to emend and reclaim saline and sodic soils. Determination of requisite water to reclaim this kind of soils and optimal management of water and soil resources are seems to be necessary. In this study, Examination of three different leaching methods including Continues pounding leaching, Intermittent pounding leaching and Spreyer leaching have been performed on saline and sodic soils in Veis area, Khoozestan. This examination performed on natural and intact soil culms with 1 meter height which are located in Polyethylene area with 15 cm diameter. The examined soil layers were 0-25, 25-50, 50-75 and 75-100 cm and the depth of leaching water were 25, 50, 75 and 100 cm. According to obtained results, and experimental method were found for estimation of each leaching method. Exponential model in Continues pounding method was defined as the best model based on better correlation coefficient and lower standard error. However, Intermittent pounding method showed lower utilized water for soil desalinization and better leaching efficiency coefficient corresponding with soil texture of the area. According to shortage of water and advantages of this method compare to two other methods, Continues pounding method will be appropriate for Veis Area. Manuscript profile
