Humic substances comprise the major organic components of soil and are produced when organic matter biodegrades, providing nutrients for plant growth. Among humic substances, fulvic acids provide supplemental plant nutrition while helping maintain soil moisture. Humic substances are complex molecular groups, formed by aromatic fenolic compounds and cycled nitrogen and aliphatic compounds, then synthesized by microorganisms present in the biomass. In short, humic substances are decomposed plant and other organic matter that provide much of the nutrients in soil. These nutrients form when organic matter in the soil – carbon hydrates, lignin, aliphatic organic acids, alcohols, aldehydes, resins, nitrogen compounds, carbon hydrates (cellulose, hemicellulose), lignin and tannins – decompose through the process of humification, forming humus, which in turn mineralize into more stable humic extracts. These extracts make the soil more fertile. Humic substances are categorized in two groups: humic acids and fulvic acids. These compounds react chemically in the soil, enabling plant assimilation of nutrients.
