The characteristics of cultivated soils developed from coastal paleosand (Korcula Island, Croatia)

摘要: The problem of maintaining soil quality and fertility developed from Pleistocene eolian sand deposits arises improper management conservation the highly fragile sandy environment. research was undertaken to determine howvarious aspects cultivated can be related specific pedological geological factors, which one these relationships plays an essential role in Lumbarda “polje”, Korcula Island, Croatia. Soil survey done by examining sampling hundred locations depth 100 cm within 40 ha winegrowing site. Geostatistical analysis applied characterize spatial variability produce map area. profiles were sampled for laboratory analysis, including physicochemical characteristics mineralogy. Modal petrographic microscopy concretions conducted as well. Two units (SU) identified, both containing more than 80% sand: SU1 Hypoluvic Arenosols, SU2 Haplic Arenosols (FAO 2006). In SU1, reddish brown color originated Fe oxide coatings on grains, whereas is characterized rise pH with presence calcite a cementing material. Cation exchange capacity significantly higher SU2. documented element content distribution indicates differentweathering stages layers. Diagrams Cr/V Co/V ratios indicate different origin deposits. Light mineral fraction dominant SU. Most grains are intensively weathered well rounded, indicating long transportation source results mineralogical geochemical characterization “polje” grapevine growing site applicable useful future studies that involve “fingerprinting” regional wines.
