Gypsum is a naturally occurring product high in Calcium and Sulfur (Calcium Sulphate). It is used primarily for correcting Sulfur deficiencies and improving soil structure.Gypsum comes in many different forms and from many different locations. We have access to all types of gypsum, including sand, seed and crystal and have been supplying these to agriculture and land rehabilitation for many years.The spreadability of gypsum will change from product to product and you need to consult your spreader operator on the application rates that can be achieved with a certain product. It is important to choose an AFSA accredited spreader operator to maximise the level of accuracy of your spreading.Bulk gypsum deliveries can be treated much as Super, although in some cases it does not require covering.
