OGS - Gypsum 1Kg NEW the residual oil will flowGypsum is a natural source of both Calcium and Sulfur (Calcium Sulfate) that corrects soil sodicity (too much Sodium). It improves the Calcium magnesium ratio of soil, which loosens the soil, improving water infiltration, soil structure and Oxygen content. The Sulfur in our Gypsum will enhance crop flavors and aromas but also plays a vital role in nitrogen fixation (Sulfur is present in the important nitrogenase enzymes that contain a Fe Mo S cluster)
