Potassium Humate is ideally suited for addition with granular fertilizers, such as Urea. With prominent effect to release the locked phosphate by some ion such as Fe3+, Al3+, also can slow-release nitrogen fertilizer to promote the function of NPK fertilizers. + function & benefits: - Improve the structure of soil, increase the buffering power of soil. Optimize N,P,K absorption by plants - Neutralize both acidic and alkaline soils, regulate the pH-value of soils, with the prominent effect in alkaline and acidic soil. - Stimulate plamt growth, increase the yeild and quality. Reduce nitrate leaking into the groundwater and protect the underground water. - Increase the effectiveness of herbicide pesticide and fungicide, immobilize or reduce their harmful residues. - Stabilize nitrogen and improve nitrogen efficiency (ideal as an additive with urea) Appearance: Black Flakes Water-solubility (dry basis) 100% Humic acid (dry basis) 70% Fulvic acid (dry basis) 5% Potassium (K2O dry basis) 10% min Nitrogen (organic) 0.35% P2O5 0.02% Moisture 15.0% max pH 8.0-10.0
