Abstract

The thermodynamic functions of southern taiga forest litter samples were determined by means of DSC. It was found that more thermostable compounds (at least in the interval 50–150°C) with higher absolute values of the Gibbs function for intermolecular structures are formed in the course of forest litter decomposition. The data obtained indicate the spontaneous nature of the processes relating to the transformation of organic matter in soil.
