Characteristics of the qualitative composition of soil organic matter: Problems and solutions

The components of soil organic matter (SOM) such as lipids (waxes, fats, and resins), pigments (oxyanthraquinones and related substances, tetrapyrrole compounds and carotenoids), kerogen, glomalins, and hydrophobins are briefly described in the paper. In the traditional assessment of the qualitative...
