POTASSIUM FULVIC ACID

Potassium fulvate is extracted from lignite with high activity by an innovative process. The product is easily soluble in water and has the characteristics of hard water resistance, non-flocculation and non-precipitation, in the PH range of slightly acid or wider, it shows very good water solubility, because of its small molecular weight and high activity of carboxyl functional group, the chelating effect of the product is enhanced, make it easier for plants to absorb mineral nutrients.
