Potassium Humate is a natural organic macromolecule extracted from high-quality weathered coal, lignite, and peat via advanced alkaline extraction and purification. It presents as black/brown amorphous powder, flakes, or granules, with good water solubility (≥95%) and chemical stability, suitable for pH 4.0-10.0 and resistant to 120℃ without decomposition. Non-toxic, residue-free, and highly compatible, it serves as an eco-friendly agent in agriculture, animal husbandry, aquaculture, and environmental protection.
