A contribution to the knowledge of forest soils of the Bosut region.     PDF     EN 317
Summary: The author presents a few results of an investigation of forest soils in the Bosut region.
The Bosut lowland area represents both the largest and main complex of the Sava basin forests. The specific ecological factors of this area have conditioned the development and subsistence of lowland forests of Pedunculate Oak belonging to the community of Querceto-Gënistetum elatae Horv.
The investigations carried out for orientation have proved that in addition to the parent material, climate etc. the formation and distribution of soil types is here considerably influenced by the relief. Accordingly there developed on higher localities - elevations - podzolized forest soils, or taking into consideration the differences conditioned by the relief etc. very weakly and weakly podzolized soils respectively. According to the most recent soil nomenclature the mentioned groups belong partly to leached brown forest soils and parapodzolic soils. On higher localities (elevations) which are under the influence of a greater moisture there developed a parapodzol (pseudogley). On this occasion there were described the profiles of podzolized forest soils as well as those of very weackly and weakly podzolized soils respectively, which belong predominantly to the leached brown forest soils. Besides the process of acidification in these soils is also being observed a downward movement of colloids from the surface horizons to deeper horizons. The examination of the content of colloid clay particles (sized < 0.002 m. m.) shows that these soils are mainly moderately to strongly colloidal.
The soils are covered with stands of Pedunculate Oak (with Hornbeam). Sometimes to these stands are admixed the following tree species: Elm and Ash, Lime and Common Maple.
On low-lying localities (depressions) occur swampy (hydrogeneous) soils. They are under the influence of stagnât surface waters as well as high-level ground-waters almost throughout the year. Owing to their heavy mechanical composition they are rather impermeable. Described was the profile of the mineral swampy and fairly humous soil on loess and mentioned were the properties of this soil as well as those of a mineral swampy and strongly humous soil. The physical properties of these soils are chiefly insatisfactory, their mechanical composition is heavy.
They are covered with stands of Ash and Oak. In swamps there occurs a swamp vegetation because they almost never dry out in the course of the year.
