Gypsum as a soil additive: use it or lose it? MSU Extension

Gypsum has been shown to be effective at treating aluminum toxicity on soils with a pH lower than 4.5. At pH lower than 4.5, aluminum in soil overpowers the ability of hydrogen ions to increase pH. Sulfate may act as a counter ion on soil particles increasing aluminum absorption from the soil solution.

Gypsum crystallization and potassium chloride regeneration

Abstract. Gypsum crystallization along with the simultaneous regeneration of KCl was investigated by the reaction of CaCl 2 solution with K 2 SO 4.Well developed sheet structure gypsum crystals were produced when K 2 SO 4 solution was added into the CaCl 2 solution by slow titration or in multiple stages over 2–8 h followed by 2 h equilibration. In order to regenerate KCl solution as
