Abstract: The aim of the study was to analyze the diagnostic properties of soils on territory of Training and Experimental Forest Range (TEFR) “Petrohan” in order to classify them according to the modern requirements of World Reference Base for soil resources. Seven soil profiles were studied. Soil samples were collected from territories in which it was known that the soils are with a clay - enriched subsoil (Luvisols). Soil classification indicators have been investigated according to the requirements of World Reference Base for soil resources. Five soil profi les were classifi ed as Acrisols and two as Lixisols. On the second taxonomy level for Acrisols apply Vetic prefix qualifier. Lixisols were identified as Vetic and Haplic. Acrisols and Lixisols were established on the territory of the TEFR „Petrohan“ in beech forests of the temperate climate zone. We assume that specific weathering processes and acidifying effect of beech forests have been playing a key role for Acrisols and Lixisols formation.
