Description
Improve Soil Structure Naturally
Certified Organic Gypsum is a natural soil amendment used to improve soil structure, increase calcium levels, and help create healthier growing conditions across gardens, landscapes, farms, and horticultural operations.
Unlike lime-based products, gypsum supplies calcium without significantly changing soil pH. This makes it particularly useful where soil structure needs improvement but pH levels are already suitable for plant growth.
Its ability to help open heavy soils and improve water movement makes gypsum a valuable addition to clay soils, compacted areas, and sites where drainage and root development are being restricted.

Why Use Certified Organic Gypsum?
Healthy soils rely on the movement of air, water, and nutrients through the soil profile.
In heavy or compacted soils, poor structure can limit root growth, reduce drainage, and affect plant performance. Gypsum works by supplying calcium, which helps improve soil aggregation and creates a more open, workable soil structure.
It is also widely used in agricultural and horticultural systems to assist with the management of sodic soils, where excess sodium can negatively affect soil performance.
Unlike dolomite or lime, gypsum provides calcium without significantly raising soil pH, making it suitable for a broader range of applications.

Why Choose Gypsum Instead of Dolomite?
While both products supply calcium, they serve different purposes.
Choose Gypsum when:
- Soil is heavy or compacted
- Drainage needs improvement
- Additional calcium is required
- Soil pH is already suitable
Choose Dolomite when:
- Soil is acidic
- Calcium and magnesium are both required
- Soil pH needs to be increased
Selecting the right amendment helps achieve better long-term soil performance and avoids creating unnecessary nutrient imbalances.
Certified Organic Quality
Certified Organic Gypsum provides a natural and effective way to improve soil structure while supplying essential calcium. Carefully selected for quality and consistency, it is suitable for gardeners, growers, landscapers, and farmers seeking practical long-term soil improvement.
