Gypsum is a slow-release source of sulphur and calcium which play a key role in improving soil structure, aeration and water retention. So you can grow better, healthier crops.
When Gypsum dissolves, it releases equal proportions of calcium and sulphate. Calcium sulphate improves the structure and consistency in soil and most other growing media allowing better water penetration and retention.
Gypsum is an environmentally friendly, natural mineral that is mined from ocean deposits formed centuries ago. It's non-toxic and not harmful to people or animals.
