WebbAs organic matter is largely derived from decomposed plant material it contains all the essential nutrients for plant growth including carbon, nitrogen, phosphorus, potassium, and sulphur. Stable elements of soil organic matter retain these nutrients in soil as part of complex organic compounds. 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).
