Abstract :
One of the problems in the soils of arid and semi-arid regions is the accumulation and presence of soluble salts and exchangeable sodium in the soil. In order to use and exploit these soils, it is necessary to modify them. In this study, an intermittent washing method was used to improve saline and sodium soils, and the water used for washing has an inappropriate quality (class C3-S1). As a result of soil modification and leaching, soil electrical conductivity (ECe) and exchangeable sodium percentage (ESP) significantly and significantly decrease, but the pH shows a slight increase. Also, in this study, the Gapon coefficient was calculated before and after washing, and its value decreased after washing.
