چکیده
Abstract Soil penetration resistance is an informative indicator to monitor soil compaction, which affects a range of ecological processes in floodplain ecosystems. The aim the investigation was reveal influence vegetation cover on spatial variability soils. study carried out elm oak forest Dnipro River (Dniprovsko-Orilsky Nature Reserve, Ukraine). profile morphology performed accordance with guidelines field description soils FAO. measured using Eijkelkamp manual penetrometer depth 100 cm at 5-cm intervals within polygon consisted 105 sampling points. Vegetation descriptions were made 3×3-meter surrounding from each point. found regularly increase increasing depth. changes values insignificant until 25–30 After that, there sharp up 70–75 cm, after indicators plateaued. In three-dimensional aspect, variation can be fractionated into broad-scale, medium-scale, and fine-scale components. Tree induces broad-scale component variations, embraces whole profile. herbaceous medium-scale component, upper middle parts influenced by pedogenic factors.
