Ida-Gro Pelletized Gypsum, or calcium sulfate, is clean and virtually dust free. It is a safe source of sulfur and calcium. Gypsum prevents and corrects sodicity, makes your soil more porous and able to absorb moisture. This will provide greater stability of soil organic matter, more stable soil aggregates, and more rapid seed emergence. Use this mix to break up heavy soil in your lawn, garden, flower beds, and more!
