Profilowe zróżnicowanie form żelaza i glinu w glebach pod świerczyn górnoreglową Plagiothecio-Piccetum tatricum w Gorcach jako wskaźnik aktualnych procesów glebotwórczych / Distribution of Iron and Aluminum Forms as an Indicator of Present-Day Soil-Forming Processes in Soil Profiles under Wooded Spruce Plagiothecio-Piccetum Tatricum in the Gorce Mts. (Southern Poland)

Abstract

AbstractThe aim of the study was to determine soil-forming processes in soils formed from the Magura sandstones (Carpathian flysch) under wooded spruce Plagiothecio-Piccetum tatricum in the Gorce Mts., southern Poland. The research focused on distribution of non-silicate forms of iron and aluminum in soil profiles. The content of pyrophosphate, oxalate, and dithionite phases of iron and aluminum in the genetic horizons of four soil profiles was measured and selected pedogenic factors were calculated. Based on the obtained results podzolization and brunification are dominant soil-forming processes in the studied soils. The brunification effect was more common in the soils under the large share of Athyrium distentifolium, whereas podzolization predominates in the soils where Vaccinium myrtillus prevails in forest floor. Studied soils were classified as Dystric Endoskeletic Cambisol (Loamic, Humic), Dystric Cambisol (Siltic, Humic) and Skeletic Folic Albic Podzol (Arenic).
