Abstract: A field experiment was conducted out on reclamation of a saline-alkali soil by agricultural drainage water (Nasr El-Din drain). The average values of EC and SAR among the experimental work were 1.91 dS/m and 6.68, respectively. This work was conducted at Mounshaet Bakhaty village, Shebin El-Kom district, Menofia Governorate to asses the efficiency of reclamation using different local amendments such as gypsum “G”, sulphur “S”, organic matter “FYM” and sand “d”. These amendments were applied individually or in a combination, where gypsum application rate was 5 ton/fed., sulphur, 1.0 ton/fed, organic matter (FYM) 20 m3/fed and sand 20 m3/fed., then the experimental plots were irrigated to leach the excess of soluble salts. Maize and wheat seeds were sowing through summer and winter seasons and the yields were harvested and recorded. The pre-leaching values of soil parameters before reclamation were: EC: 8.3 dS/m, others were; ESP: 17.2, pH: 7.9 in the surface layer (0-30 cm).
The obtained results could be summarized as following:
1- Effect of amendments application on soil chemical properties:
A great reduction in soil salinity values were recorded after the application of soil amendments being 54.3% under (G+S+FYM+d) treatment after wheat compared to the control.
Soil acidity (pH) slightly decreased from 8.15 to 7.75 under the application of (G+S+FYM), (S+FYM+d) and (G+S+FYM+d) in the same value.
