GYPSOIL brand gypsum is an important source of two vital nutrients needed in crop production, calcium and sulfur. It supplies 17-20% calcium and 13-16% sulfur, depending on the exact production source. Long term gypsum users recently rated 23 benefits associated with gypsum application and they ranked sulfur availability as the 2nd most important benefit associated with use, after yield increases.
Calcium is an important nutrient for root development and growth in row crops and for enhancing soil particle flocculation. Peanut growers have long used gypsum or land plaster to meet the requirements of large seeded varieties prone to pod disease and poor development without adequate calcium. Crops, such as potatoes and tomatoes, also benefit from calcium supplementation and are ideal for gypsum treatments. More about using GYPSOIL peanuts.
Corn, cotton and alfalfa growers, among other crop producers, reap the benefits of using gypsum as a fertility tool to supply sulfur. Ironically, this important macro-nutrient is deficient in many soils today, in part because desulfurization systems at coal-fired utilities have effectively reduced acid rain. Signs of sulfur deficiency include yellowing of top leaves and at times leaf streaking but are sometimes misdiagnosed. GYPSOIL brand gypsum is in the sulfate form which is immediately-available to plants.
