Abstract
In the article is analyzed the soils’ properties in near-highway road strips of M-10 Lviv-Krakovets with width up to 150 m. Within the near-road strips of the highway, have been established 12 experimental polygons under forest, meadow vegetation and agricultural lands. On each polygon from soils profile samples are selected the most common soils: sod-podzolic, formed on fluvio-glacial and gray-forest soils formed on loess loam. Completed description of soil profiles to depth of 0- 100 cm. Part of experimental soils are formed under hornbeam-beech forests (11, 12 polygons) and oak-hornbeam-pine (4, 6, 7, 8 polygons). The researches revealed that in soil profiles at different depths are lie buried in eolian forms of relief (dunes) with different steepness of slopes. The steepness of the walls of the superficial layers of the dunes varies from 10 to 30°. In the research profiles of near-highway soils on the surface of the dunes, find presence of progumed fragments of strips up wide to 2–3 cm. On the territory of the Nadsyanska moraine-sandur alluvial plain at a distance of 50 m from the roadway (polygon 2, in the valley of the river Shklo, where the grassland vegetation is predominant, the turfy shallow gluten sandy soils are formed on alluvial deposits) discovered two low-power buried humus horizons who inherited a deflationary relief. Their steepness on the surface of the dunes is about 10 °. In polygon 3, the incision is laid in the micro threshold of the ancient relief, where the vegetation is represented by a spruce forest with oak impurities. In the profile of sod-hidden-podzolic sandy soil, on the surface of buried dunes which have steep walls 10-20°, are observed a humus layers . In the polygon 12, which is laid in the southwestern spurs of Roztochya 1,5 km north of the village of Birky in the hornbeam forest, steepness of the walls superficial layers of dunes of western exposition ranges from 10 to 12°. The soil is a clear-gray forest-loamy on loess loamy. In the soil profiles have been identified the following chemical elements: Pb, Zn, Co, Cu, Ni, Mo, Cr, Mn, V, Ba, Sr, Zr, Fe, Ti, Sn. The researches have established that in the territory of the Nadsyanska moraine-sandur alluvial plain, and in the south-western spurs of Roztochchya, widespread buried dune relief. Based on our research, we propose to consider the issue of the allocation of types (subtypes) in soil legends, to investigate the deflations and interdeflation periods of their formation.
