Pelletized Gypsum

Pelletized gypsum provides calcium and sulfur for optimum plant health and growth. Commonly known as Cal-Sul™ and SuperCal SO4®, pelletized gypsum is OMRI-listed with a typical analysis of 21 percent calcium and 17 percent sulfur. Midwestern BioAg recommends adding pelletized gypsum to fertilizer blends because the pellets hold together in transport but break down quickly in the soil for easy, clean and accurate application.
