A traditional 50-pound bag of 22-0-4 fertilizer contains about 20 pounds (or 40%) of rock limestone filler. This material provides no agronomic benefit.
In our 22-0-4 and 9-12-6 fertilizers, we’ve replaced the limestone filler with our Black Gypsum DG and DG Gypsum, which deliver carbon, calcium and sulfur.
The 9-12-6 fertilizer also features both SmartPhos® DG and MAP, providing both slow-release and quick-release phosphorus sources.
