Gypsum

Calcium Sulphate

Gypsum is a naturally occurring mineral perfect for slow-release calcium and sulphur playing a key role in soil structure, aeration and water retention. Gypsum breaks down slowly releasing equal proportions of calcium and sulphur.

Calcium is key to improving soil structure and consistency, enabling optimum moisture penetration and retention as well nutrient transportation. Gypsum breaks up clay by expanding the calcium to magnesium ratio flocating your soil.
