ON THE SEMANTIC STRUCTURE OF TAXON NAMES IN SOIL CLASSIFICATIONS
2025
O. G. Chertov
The leading role of the «living matter of the biosphere» according to V. I. Vernadsky as a biological factor of soil formation, which leads to the accumulation of soil organic matter (SOM), is emphasized. SOM is the main solid-phase product of the influence of plants and soil biota in the process of soil formation. The unsatisfactory reflection of the SOM attributes in the existing soil classifications is noted. A structural change in the taxon names in the Russian soil classification is proposed, taking into account the types of SOM transformation. The concept and taxonomy of humus forms are proposed as a basic type of SOM transformation. This format of taxon names has been successfully used in soil mapping in forest inventory and in the forest typological researches. Such a taxonomy expands the information content and gives dynamism to the soil classification, which is especially important in conditions of increasing anthropogenic stress and a rapidly changing natural environment.
