Potassium Humate (CAS 68514-28-3), 60–70% humic acid, shiny flakes, powder and granules, supplied wholesale by Zyntex. Soil conditioner, biostimulant and fertilizer additive for fertigation, foliar sprays and blends. CoA and SDS.
Potassium humate is a black, water-soluble flake, powder or granule made by extracting leonardite, a highly oxidized lignite, with potassium hydroxide. Typical grades contain 60–70% humic acid, some fulvic acid and 8–12% potassium (K2O).
In addition, farmers and fertilizer producers use it to improve soil structure and water retention, increase nutrient uptake and cation exchange, and stimulate root growth. It is applied through irrigation and fertigation, in foliar sprays, and blended with granular fertilizers such as Urea and Monoammonium Phosphate (MAP). Similarly, turf and horticulture users use it in soil conditioners.
Notably, related agricultural products in our range include Gibberellic Acid (GA3) and Potassium Nitrate.
