The formation of humic substances in nature is one of the least understood aspects of humus chemistry and one of the most intriguing. There are three main theories to explain it: the lignin theory of Waksman (1932), the polyphenol theory, and the sugar-amine condensation theory of Maillard (1911). Those theories are insufficient to account for observations in soil research. Humic substances are formed by the microbial degradation of dead plant matter, such as lignin a…
