0-0-30

High-potency potassium from potassium carbonate. Strong drought resistance, water regulation, stress tolerance. Compatible with drip, ground, and aerial application. Every ton of hay you harvest removes roughly 45–60 lb of potash (K₂O) but only 13–15 lb of phosphate (Penn State Extension), which is why a triple like 19-19-19 is the wrong ratio for hay, and why we recommend 0-0-30 instead.
