Soils formed in high mountainous regions in southern Brazil are characterized
by great accumulation of organic matter (OM) in the surface horizons and variation in the
degree of development. We hypothesized that soil properties and genesis are influenced by the
interaction of parent materials and climate factors, which differ depending on the location along
the altitudinal gradient. The goal of this study was to characterize and classify the soil, evaluate
soil distribution, and determine the interactive effects of soil-forming factors in the subtropical
mountain regions in Santa Catarina state. Soil samples were collected in areas known for wine
production, for a total of 38 modal profiles. Based on morphological, physical, and chemical
properties, soils were evaluated for pedogenesis and classified according to the Brazilian System
of Soil Classification, with equivalent classes in the World Reference Basis (WRB). The results
indicated that pedogenesis was strongly influenced by the parent material, weather, and
relief. In the areas where basic effusive rocks (basalt) were observed, there was formation of
extensive areas of clayey soils with reddish color and higher iron oxide contents. There was a
predominance of Nitossolos Vermelhos and Háplicos (Nitisols), Latossolos Vermelhos (Ferralsols),
and Cambissolos Háplicos (Cambisols), highlighting the pedogenetic processes of eluviation,
illuviation of clay, and latosolization in conditions of year-long, large-volume, well-distributed
rainfall and stability of land forms. In areas with acid effusive rocks (rhyodacites), medial or
clayey soils were observed with lower iron oxide content, invariably acidic, and with low base
content. For these soils, relief promoted substantial removal of material, resulting in intense
rejuvenation, with a predominance of Cambissolos Háplicos (Cambisols) and lesser occurrence
of Nitossolos Brunos (Nitisols) and Neossolos Litólicos (Leptosols). Soils formed from sedimentary
rocks also tended to be more acidic, but with higher sand content, and the soils identified were
Cambissolos Háplicos and Húmicos (Cambisols). Cluster analysis separated the soil profiles
into three groups: the first and largest was formed by profiles originating from sedimentary
rocks and rhyodacites; the second, smaller group was formed by four profiles in the Água Doce
region (acidic rocks); and the third was formed by profiles derived from basalt. Discriminant
analysis was effective in grouping soil classes. Thus, the study highlighted the importance of
geology in the formation of soils in this landscape associated with climate and relief. MenosSoils formed in high mountainous regions in southern Brazil are characterized
