Soil pH…Does Gypsum Help Read below to find out EcoGEM

Gypsum will not reduce soil pH Calcium in the gypsum will displace H but the H remains in the soil solution so there is no change in soil pH due to gypsum per se In very acid sub soils pH or less aluminum becomes more soluble and is toxic to roots tips Calcium leaches into the subsoil and displaces some of the Al so it leaches below
