The studding of desodification of saline and sodic soils at central region of Khuzestan Province

Management of natural resources such as water and soil is one of the important subjects in suppling food requirements of increasing population of the world. Soil salinization and sodification caused by salt accumulation are the common phenomena that manifest in irrigated agriculture in arid and semiarid regions. The aim of this research was study of desodification of saline and sodic soils at central region of Khuzestan province-IRAN. For this purpose, two experimental areas (Sl, S2) were selected and four treatments with three replications by series of double rings were applied. The treatments included 25, 50, 75 and 100 cm water application. It was concluded that 39 and 55% of initial exchangeable sodium percentage in Pilot S1 and S2 was reduced by 100 cm water leaching at one meter layer of Soil respectively.
