Granular Gypsum – Clay Buster!

Slow-Release Calcium Sulphate for Soil Remineralisation and Rejuvenation

Granular Gypsum is a natural, slow-release source of calcium sulphate designed to rebuild tired, compacted, or worn soils by restoring essential calcium levels. Its mini prill granules (1-2mm) make it ideal for even application with minimal dust, perfect for home gardens, landscaping projects, parks, school ovals, and commercial or industrial use. By improving soil structure and nutrient balance, this clay buster helps promote healthier, more productive soils. It helps correct soil calcium levels and rebuilds tired and worn soils through remineralisation.

Why choose Granular Gypsum? 

• Slowly releases calcium and sulfur to correct nutrient deficiencies
• Improves soil structure and reduces compaction
• Minimises dust for easy, clean application
• Small granule size ensures even distribution
• Suitable for gardens, parks, ovals, landscaping, and commercial projects
• Helps rejuvenate worn and tired soils naturally

How to use - By Area: 

Home Gardens & Lawns

Apply evenly to garden beds, flower beds, and turf areas to improve soil health and nutrient availability.

Landscaping & Parks

Ideal for large-scale landscaping, school ovals, and community green spaces needing soil remediation.

Commercial & Industrial

Suitable for road works, industrial sites, and commercial projects requiring soil rebuilding and calcium supplementation.

What It’s Made From: Natural Calcium Sulphate (Gypsum), Free from additives or fillers and Small prill granules (1-2mm) for easy spreading. 

The Science Behind Gypsum Granules

Granular Gypsum supplies calcium and sulfur—two essential nutrients that play a critical role in soil health and plant growth. Calcium is a key structural element that helps improve soil aggregation, breaking up heavy clay particles and reducing compaction. This creates better soil porosity, enhancing air circulation and water infiltration, which are vital for healthy root development. Sulfur, supplied slowly through gypsum, is crucial for synthesising proteins and enzymes in plants, supporting overall growth and crop quality. It also plays a role in chlorophyll formation and improves nitrogen use efficiency.

Beyond nutrient supply, gypsum acts as a natural soil conditioner by displacing harmful sodium and magnesium ions from the root zone, especially in sodic or saline soils. This ion exchange reduces soil toxicity and restores a balanced soil chemistry, which encourages beneficial microbial activity essential for nutrient cycling and organic matter breakdown. The slow-release nature of granular gypsum ensures a steady supply of calcium and sulfur over time, reducing nutrient leaching and providing long-lasting soil improvement. This gradual nutrient availability supports sustained plant growth and resilience, particularly in soils prone to nutrient depletion or compaction.

By improving soil structure, moisture retention, and nutrient availability, granular gypsum creates an optimal environment for roots to expand, enhancing the uptake of water and essential minerals. This results in healthier plants, increased yield potential, and better tolerance to environmental stresses like drought or heavy rainfall.
