Soil salinity is one of the major problems affecting the development of agriculture in arid and semi-arid areas because of the impact of salt on the physicochemical characteristics of the soil and its low productivity. This research was carried out with the aim of studying the effect of applying different washing waters combined with some amendments such as agricultural gypsum and organic material on salt movement through a saline loamy soil. It was done through a pot experiment according to a Completely Randomized Design (CRD) with three replications for each treatment consisting of five treatments as follows. The results indicated a significant reduction in the salinity of the soil since there was a considerable reduction in the ECe values from 8.50 to 3.10 dS/m for the gypsum treatment (T4). Similarly, there was a considerable reduction in the SAR values from 12.0 to 4.2, as well as a significant reduction in the ESP values from 18.0% to 7.8%. The filtered water (T2) had a significant reduction in ECe values to 4.20 dS/m, whereas the saline water (T3) had the least effective rate of reducing soil salinity with values at 7.05 dS/m. There was also a significant reduction in the ECe values to 4.90 dS/m with an improvement in the physical characteristics of the soil in the organic matter treatment (T5).
