Lime & gypsum kzndard.gov.za

Lime raises the pH of soils by neutralizing hydrogen ions. Gypsum will not neutralise acid soils or effectively raise pH. Lime may be used as a source of Ca in low-Ca soils. Gypsum may be used as a source of Ca and of S. Lime won’t effectively reclaim sodic soils unless elemental sulphur or sulphuric acid is added. Gypsum reclaims sodic soils by replacing Na with Ca.
