Introduction to Premium Granular Humic Acid
Granular humic acid potassium humate represents a revolutionary advancement in soil amendment technology. Unlike conventional powdered or liquid humates, our high-hardness potassium humate granules (10% moisture content) are specially engineered for perfect compatibility with blended fertilizers. With 65% humic acid content and 10% potassium oxide (K₂O), this premium soil conditioner delivers unparalleled agronomic benefits while maintaining perfect physical stability in fertilizer blends.
Why Choose Our Granular Humic Acid?
