Because the healthiest turf comes from the healthiest soil, SO4 is made from 95% pure natural-mined gypsum, the purest available, and pelletized in two sizes idealized for green or fairway/tee box applications. Improve soil structure, increase rooting depth, and enhance watering efficiency by 25-100% as SO4's high-quality calcium removes harmful magnesium from your soil. SO4 stimulates soil biology, reducing thatch and improving water infiltration. Root depth is improved as the calcium and sulfur in SO4 work down into the soil profile, creating more pore space and spreading vital nutrients throughout. Less-frequent watering and fertilizing are necessary, and because of the purity of SO4, you can apply without any special licenses, warning signs or re-entry intervals. Our specialized pellets require far less product per application, so be sure to use our product calculator to determine your needs.
