GreenMag Gypsum + 5% Magnesium
GreenMag is a formed calcium sulphate dihydrate & magnesium sulphate 2-4mm granular gypsum using superior binding technology. GreenMag 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). This powder is then blended with magnesium sulphate into an homogeneous blend which is then bound into the 2-4mm granular form. Binding GreenMag 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, GreenMag simply disperses back to its powdered form and becomes available in the soil profile. The very high purity and ultra fine particle size of GreenMag gypsum make it readily available in the soil compared with agricultural gypsum products.
GreenMag supplies readily available calcium, sulphur and magnesium in one pass without significantly affecting soil pH. GreenMag is suitable for spreading using standard spreading systems. GreenMag is used in small horticultural crops and tree cropping as well as being used by greenkeepers on golf fairways and on sports playing surfaces.
