GreenCal gypsum granular is a formed calcium sulphate dihydrate 2-4mm granular gypsum using superior binding technology. GreenCal granular is formed from GreenCal gypsum powder which is a natural 98% pure calcium sulphate dihydrate 45 to 75 micron powder (95% passing through 45 micron). Binding GreenCal from its powdered form to a granular form allows the product to be easily spread into the areas where it is needed. When moisture is applied, GreenCal granular simply disperses back to its powdered form and becomes available in the soil profile. The very high purity and ultra fine particle size of GreenCal granular gypsum make it readily available in the soil compared with agricultural gypsum products.

GreenCal gypsum granular supplies readily available calcium and sulphur without significantly affecting soil pH. GreenCal gypsum granular is suitable for spreading as a straight using standard spreading systems. The superior strength of the granules also allows GreenCal granular to be used in fertiliser blending equipment.
