In order to evaluate the effect of bicarbonate ions in saline irrigation water in Ras Sudr Research Station where calcareous and sandy loam textured soil is dominant. Four levels of bicarbonate (initial level of well water 2.5, 5, 10, and 15 meqL^-1), different additions of farmyard manure (0,10, and 20 m³ fed^-1) and three rates of sulphur (0, 250 and 500kg S fed^-1). The obtained data revealed that both soil EC and soil pH increased with increasing bicarbonate concentration more than 5 meqL^{-1 in irrigation water. However soil EC and pH were decreased with increasing FYM and or sulphur rates. Soluble Na+} and K⁺ were increased with increasing HCO₃^- concentration, in irrigation water but soluble (Ca⁺⁺ & Mg⁺⁺) were lowest in case of (5 meqL^-1 HCO₃^-). The effect of FYM and S were clear in case of OM₂ S₂. The low value of soluble chloride occurred with adding 10 m³ fed^-1under HCO₃^- rates 2.5 and 5 meqL^-1. Farmyard manure of 10 m³ fed^-1 was the best treatment, which improved the leaching of sulphate salts.
