Understanding the “acric” Illuvial soils in Slovenian soil classification in relation to Acrisols

Turniški, Rok (author), Grčman, Helena (author), Zupan, Marko (author)

The aim of our study was to clarify the use of the term “acric” in the Slovenian soil classification and its relation to the Acrisols of the World reference base for soil resources. A comprehensive review of Yugoslavian and Slovenian soil literature from 1960 to the present revealed that the term “acric” was first introduced into the classification of Yugoslav soils in 1973, based on FAO Legend (1968). “Acric” properties were most often associated with Illuvial soils (soils with argic horizons) of the Dinaric karst region. A detailed review and analysis of soil properties of 81 profiles with argic horizons from the Slovenian Soil Map database were done. Results clearly showed that soils with argic horizons are neither Acrisols nor Lixisols according to the latest WRB soil classification, as no soils with low activity clay in argic horizons have been proved so far. The base saturation and some recent measurements of effective base saturation indicate that Luvisols are the predominant Illuvial soils in Slovenia, with possible development to Alisols. Inconsistent use of the term “acric,” especially in the context of its translation to WRB reference group Acrisols, can lead to misunderstandings about the properties of such soils.
