The pot experiments were carried out under the conditions of the glass house at the Faculty of Agriculture, University of Aleppo. The aim of the present study is to determine the role of gypsum and humic acid on some chemical properties of irrigated soil by saline water. The experiment was designed in a split second-order manner, with the main sections containing three levels of salinity irrigation water using sodium chloride salt as (W1:0, W2:3, W3:6 g𝓁-1). Three levels of gypsum were mixed: as (G1:0 , G2:25, G3:50 g). Three levels of acids were added with irrigation water as (H1:0,H2:24, H3:48 kg/he). The experiments for application leaching factor with irrigation water were carried out for treatment (W2,W3) at two levels as (%10 and %20) of field capacity, respectively. The results showed that the salt accumulation was higher when applied the leaching factor (W2), while the salt accumulation was decreased when the wash factor (W3) was applied. The addition of gypsum levels contributed for increasing in EC values, especially in the surface layer. The role of humic acid was effectively demonstrated in saline soils (W3, W2), where the concentration of sodium ions, SAR and ESP were significantly reduced when applying a high level of humic acid with irrigation water. The SAR values and the sodium-sodium ratio (ESP) were affected by the accumulation of salts in the surface layer.
