Pure gypsum is 23.3% calcium and 18.6% sulfur, making it an outstanding source of two important crop nutrients.
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.
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 micro-nutrient is deficient in many soils today, in part because desulfurization systems at coal-fired utilities have effectively reduced acid rain. GYPSOIL is an excellent source of sulfur. Read more
