Gypsum works on improving spoil structure in two ways. Both depend upon the gypsum being dissolved by rain or irrigation water and entering the soil solution. The first is called the electrolyte effect which is based on the fact that swelling and clay dispersion of sodic clay soils decrease as the salinity of water
In deciding which gypsum to buy, the main points to consider are: the total cost of supply and application of gypsum, expressed on the basis of pure CaSO4.2H20 (Regyp - 90%+ pure), how quickly the gypsum dissolves in water (Regyp - up to four faster), how easily and evenly it spreads (Regyp - up to 30%
