ProScape® 20-0-25 100% Expo® is a cost effective, homogeneous fertilizer that delivers controlled release sulfate of potash that lasts twice as long as an equivalent amount of sulfate of potash. The controlled release potash vastly reduces leaching of potassium allowing it to be used by the plant more efficiently. The nitrogen component is Meth-Ex® 40. This product is excellent for use on greens when recovering from aeration.
