Use limestone to raise pH of acid soils, and elemental sulfur to lower pH of alkaline soils. However, if soil is alkaline because of high bicarbonate ions, or if irrigation water contains bicarbonate, the soluble calcium in gypsum reacts with the bicarbonate to form insoluble calcium carbonate. The pH of the soil is decreased to the range of 7.5 to 7.8 when bicarbonate is reduced. Also ...
