HumiPure
Welcome to us
Leonardite, The decomposition of the biomass of plant origin starts with a chemical-biological oxidation, during which the basic compounds of Humic Substances are formed from lignins, tannins, flavonoids, glycosides, etc. Other parts of the biomass, such as proteins, cellulose and other carbohydrates decompose. Later in the Humification process most molecules undergo a transformation, that results in the formation of a quinon-hydroxi-carboxyl structure, then a polymerization.
Leonardite Raw Materials, We use raw materials of exceptional quality for our production purposes. Our origin leonardite deposits are of the best quality materials in China. After careful selection and thorough physical separation of the raw material, we manufacture products for ecological farming and companies that require high quality humic acids for their formulations.
