Calcium is a turf grass macronutrient
Gypsum supplies Calcium (Ca) and Sulfur (S) to the soil without adjusting soil pH; counteracts salt damage; improves CEC and increases soil porosity. Gypsum improves soil chemistry and soil structure.
Calcium is a turf grass macronutrient — essential to cell wall structure and membrane permeability — making a more resilient and robust turf plant.
