22-0-4 Fertilizer with HCU and Black Gypsum DG
A traditional 50 lb. bag of 22-0-4 fertilizer contains approximately 20 lbs (or 40%) of rock limestone filler. This filler is not detrimental to turfgrass, but it also provides no agronomic benefit.
By contrast, our 22-0-4 fertilizer with HCU and Black Gypsum DG product has the limestone filler removed and replaced with our Black Gypsum DG soil amendment, which delivers both calcium and sulfur. Now, landscape professionals can apply their 22-0-4 fertilizer while simultaneously improving their soil health. Soil health improvements are achieved through the addition of humates in both Black Gypsum DG and the Humic Coated Urea.
