Solution Grade Gypsum


Our supplier of Gypsums are Diamond K, United States Gypsum Company, and Western Mining and Minerals. The same gypsum is also ground to a much finer grind and marketed in 50 pound bags and 2,400 pound tote bags, which are handled with fork lifts. This grind of gypsum is so fine that when dissolved in irrigation water, the gypsum can be applied through drip irrigation systems. 95 percent of the gypsum will pass through a 325 mesh screen. Growers are installing silos to receive bulk loads of gypsum in pneumatic trucks.
