Summary A CONTRIBUTION TO THE CLASSIFICATION OF SOILS UNDER BEECH AND FIR FOREST (ABIETI-FAGETUM PANNONICUM PROV.) ON MEDVEDNICA The author gives a contribution to the classification of soils on which the beech and fir forest (Abieti-Fagetum pannonicum prov. Rauš 68) is developed on Medvednica (Zagrebačka gora). In the works concerning the pedogenetic investigations of Medvednica, that is the areas of beech and fir forest, the terms for soil units and the criteria of the classification system are used according to the works of: P. Kovačević , M. K a 1 i n i ć et al., 1967 and 1972, and according to the new classification of Yugoslav soils prepared by A. Š k o r i ć, G. F i 1 i p o v s k i, M. Ć i r i ć, 1972. The soils under the beech and fir forest on Medvednica were formed on silicate rocks, and to a lesser extent on siliceous colluvium (diluvium). As a contribution to the soil classification, this paper describes and separates the following soil units: Ranker s (Humous-siliceous soils) on paleozoic green schists, with dystric and browned subtypes. On Quartz-silicate metamorphic and sediment rocks (schists, quartz sandstones, grindstones etc.) the dystric cambisols (acid brown soils) are described and the following subtypes distinguished: typical acid brown soils, humous dystric brown soils and the ilimerized subtype of dystric brown soil. On quarz schists, the soil stage related to the humous subtype of dystric brown soils is also described. According to its properties, this soil stage is a gradual transition between acid brown and brown podzolic soils. In the contact zones of acid brown soils and siliceous-calcareous diluvial substrata of some parts of Medvednica, the description is given of the c o 11 u- v i a 1 (diluvial) soils. The following subtypes are distiguished: dystric siliceous colluvium and eutric siliceous colluvium. |
