- Аннотация: International soil classification system—World Reference Base for Soil Resources—has been publishedevery eight years since 1998, and in each version the number, content, and status of qualifiers waschanging. According to the WRB principles, qualifiers, both Principal and Supplementary, reflect soil-formingprocesses. Analysis of all qualifiers (281) in the latest version of 2022 showed the priority of diagnostichorizons as criteria for identifying both categories of qualifiers, as well as of chemical soil properties. Amonganthropogenic qualifiers, technogenic ones are more numerous and diverse. The number of qualifiers is maximumin soils, scattered over the world (Technosols, Cambisols, Gleysols) and minimum in strictly geographicallylocalized soils (Nitisols). Based on their relation to soils, qualifiers are subdivided into universal,identified in almost any soil (by texture, or gley properties), and unique, characteristic of individual soils. Thefunction of the Principal qualifiers is to create a central image of the Reference Soil Group; however, theirnumber can be excessive. Most similar in terms of the set of Principal qualifiers were the pairs of Referencegroups: Stagnosols and Planosols, Calcisol and Gypsisol, Alisols and Acrisols, which is due to the similarityof the processes that form them. The Reference groups Histosols and Gleysols are characterized by the mostunique set of Principal qualifiers. In constructing the names of qualifiers, in addition to Latin and Greekmorphems, formative elements from 26 world languages were involved. As an example of approaches to theanalysis of qualifiers, the Podzols Reference Soil Group is considered.
