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.

- Releases calcium and sulphur into the soil.
- Promotes healthy root growth.
- Will not upset the soil's pH balance.
