Properties and classification of soils developed on Holocene river deposits in upper San river valley near Tarnawa Wyżna

The paper presents a study of the diversity of soil properties on a sequence of Holocene river terraces. The main properties taken into consideration include soil profile morphology, particle size distribution, organic carbon content, pH and base saturation. Changes in these properties are discussed in relation to literature concerning soil development on alluvial materials throughout Europe and explained as a result of different time of evolution since the cease of flooding. The systematic position of the studied soils within the new Polish soil classification is also presented as well as their classification according to the international WRB system.
