Fulvic acid, one of two classes of natural acidic organic polymer that can be extracted from humus found in soil, sediment, or aquatic environments. Its name derives from Latinfulvus, indicating its yellow colour. This organic matter is soluble in strong acid (pH = 1) and has the average chemical formula C135H182O95N5S2. A hydrogen-to-carbon ratio greater than 1:1 indicates less aromatic character (i.e., fewer benzene rings in the structure), while an oxygen-to-carbon ratio greater than 0.5:1 indicates more acidic character than in other organic fractions of humus (for example, humic acid the other natural acidic organic polymer.
