Diamond K Gypsum has introduced a prilled gypsum product line intended to supply sulfate sulfur and calcium in a single application, CropLife Fertilizer reported. The company is marketing Premium Prill Gypsum to growers facing high sulfur prices and water shortages, claiming that it can lower nutrient and application costs while reducing runoff and soil crusting.
The line uses mined calcium sulfate dihydrate gypsum that is processed and manufactured into prills in Utah. According to the report, the products are designed for blending and broadcast application after harvest and ahead of the growing season, targeting depleted sulfur and calcium levels. CropLife Fertilizer said the line is available through leading agrichemical dealers across the United States, although it did not identify individual distributors.
Tom Tankersley, Diamond K Gypsum’s director of sales, presented Premium Prill and Premium Prill HA as lower-cost options during a period of elevated sulfur and sulfate fertilizer prices. He said the sulfate supplied by the company’s gypsum costs hundreds of dollars less per ton than sulfate fertilizers such as ammonium sulfate. Tankersley also argued that the calcium supplied alongside sulfur could reduce growers’ need for separate calcium applications. Those savings are supplier claims; the report provides no product prices or detailed application-cost comparisons.
CropLife Fertilizer reported that the gypsum mined and processed near Richfield, Utah, contains 18% sulfur and 23% calcium. Diamond K’s milling process breaks the gypsum into a fine powder before it is formed into prills held together with lignosulfonates. Tankersley described the nutrients as highly pure and soluble, linking those characteristics to their availability to crops following application.
The company also positioned the launch as a response to soil salinity, nutrient tie-up and water constraints, alongside pressure from fertilizer costs and low crop commodity prices. Tankersley claimed that domestic production offered consistent supply without supply-chain difficulties. The report sets out Diamond K’s commercial and agronomic case for the line but does not present independent field results supporting its claimed water savings or nutritional performance.
