Increases the availability of nutrients in the soil Nitrogen, potassium, calcium, sulfur, and zinc are more available to the plant after gypsum treatment. Increases yields from problem soils Healthy root systems and efficient uptake of water and nutrients improves crop yields and reduces disease susceptibility. You don't pay for or worry about harmful impurities because it's easy to handle and environmentally safe. Full season soil availability Course particles dissolve at slower rates than fine particles. Fine particles quickly dissolve in early irrigations for fast results.
Coarse particles dissolve slowly in later irrigations for continued results all season long.
USG has more than 50 years of gypsum mining experience. Local availability Verdegaal Brothers stockpiles gypsum in the heart of the San Joaquin Valley for easy access. 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. 95 percent of the gypsum will pass through a 325 mesh screen. Growers are installing silos to receive bulk loads of Aqua Cal in pneumatic trucks.
