Fulvic Acid
Leonardite Fulvic Acid is extracted from peat, lignite and weathered coal. Fulvic acid is a short carbon chain small molecular structure substance extracted from natural humic acid. It is the water-soluble part of humic acid with the smallest molecular weight and the highest active group content. It is widely present in nature. Among them, the proportion of fulvic acid contained in the soil is the largest. It is mainly composed of natural, small molecular weight, yellow to dark brown, amorphous, gelatinous, fatty and aromatic organic polyelectrolytes, and it cannot be represented by a single chemical formula.
