Application of elemental sulfur may help by producing additional gypsum in the soil. Sulfur is oxidized in soils by sulfur bacteria and the resulting sulfuric acid reacts with calcium carbonate to produce gypsum. Addition of sulfuric acid directly into the irrigation water has also been proven to improve soil permeability and reduce the hazards associated with soil sodicity. Care must be taken when utilizing sulfuric acid to ensure that the pH of irrigation water remains above 5.5. Lower pH irrigation water will begin to break down and erode concrete ditches.
