Humic Acid is a by-product of the biodegradation of organic materials

Humic substances are organic chemicals that are key components of humus, the fundamental organic component of soil, peat, and coal (and also a constituent of many upland streams, dystrophic lakes, and ocean water). For a long period in the 19th and 20th centuries, humic substances were studied through the lens of acid?base theory, which classed humic acids as organic acids and their conjugate bases, humates, as essential components of organic matter. From this perspective, humic acids are organic molecules separated from soil that coagulate (form small solid pieces) when a strong-base extract is acidified, whereas fulvic acids are organic acids that stay soluble (stay dissolved) when a strong-base extract is acidified.
