Studies on the structure and origin of soil humic acids by curie point pyrolysis in direct combination with low-voltage mass spectrometry
TLDR
In this article, Curie point pyrolysis in combination with low voltage mass spectrometry has shown that humic acids extracted from three typical Indian soils have similar structures which resemble that of a fungal "humic acid" rather than that of lignin.Abstract:

Chapter 1 Humic Substances: Chemistry and Reactions
TL;DR: Humic substances are major organic constituents of soils and sediments and are widely distributed over Earth's surface, occurring in almost all terrestrial and aquatic environments as discussed by the authors, and Humic substances arise from the chemical and biological degradation of plant and animal residues and from synthetic activities of microorganisms.

Decomposition and distribution of residual activity of some 13C-microbial polysaccharides and cells, glucose, cellulose and wheat straw in soil
TL;DR: In this paper, the rate of decomposition of some 14C-labeled microbial polysaccharides, microbial cells, glucose, cellulose and wheat straw in soil, the distribution of the residual 14C in various humic fractions and the influence of the microbial products on the decomposition of plant residues in soil.
