IronPro Fast Acting Iron Supplement is a unique concentrated formula that provides a deep green lawn without the excessive growth caused by some nitrogen-rich fertilizers. Use any season, on any type of grass for a deeper green in days! IronPro Fast Acting Iron Supplement features a proprietary, patent-pending chelation technology to improve iron uptake in plants. Chelation is a process that helps transform nutrients into soluble forms that are easily taken up by plants and beneficial soil microbes. Our unique chelating approach is proven to increase iron uptake by 65% more than grass treated with a competing iron supplement at 45 days after treatment. And with double the iron, you'll achieve a deeper green lawn that lasts.
