Liquid 6-24-6-1S Starter Fertilizer
Our 6-24-6-1S is a high-purity liquid plant food manufactured entirely from high-grade, 100% ortho white phosphoric acid (arsenic free), potassium hydroxide, ammonium thiosulfate, and ammonium hydroxide. One of the first 100% orthophosphate 6-24-6-1S formulations on the market, it has become our fastest-growing product — and for good reason.
With the highest phosphorus content in our lineup, it delivers exceptional early-season nutrient availability in a form plants can access immediately. The 100% orthophosphate source means phosphorus is already in plant-available form, with no conversion required — a meaningful advantage over polyphosphate-based competitors. The addition of sulfur supports protein synthesis and overall crop development throughout the season.
Its very low salt index and carefully engineered chemical formulation make it more seed-safe than most comparable plant foods on the market, suitable for in-furrow, starter, and foliar applications. Clear and water-white in appearance, it mixes cleanly without residue or equipment issues.
