Edafski potencijali bukovih šuma Brezovice

Abstract

U radu su prezentirani rezultati proučavanja zemljišta u planinskoj šumi bukve (Fagetum moesiacae montanum Jov. 53) na području planinskog masiva Brezovice. Proučena zemljišta u monodominantnoj zajednici bukve formirana su na krečnjaku i argilošistima. Na krečnjaku su proučene četiri razvojne forme: crnica, posmeđena crnica, smeđe zemljište, ilimerizovano zemljište. Na argilošistima je proučen jedan tip zemljišta: kiselo smeđe zemljište.

The study deals with the soils in the montane beech forest (Fagetum moesiacae montanum Jov. 53) in the management units "Južni Kučaj II" and "Bogovina I", on the mountain massif Brezovica. Soil genesis in the beech forests of Brezovica, along with vegetation and relief, was affected by the character of parent rock. The study soils occur over two types of bedrock: limestone and argilloschist The soil types and sub-types are defined based on the profile morphology, parent rock and pedogenetic processes Two types of soil were analysed on limestone: black earth (calcomelanosol) and brown soil (calcocambisol). Two sub-types of black earth were defined: organomineral and brownised. There are two varieties of organomineral black earth: colluvial and lithic. Also two sub-types of brown soils were defined and: typical and illimerised. The soils on limestone are characterised by great spatial variability. Different combinations of soil formations occur on a small area. Soil combinations consist of two or three development phases, the most represented of which are the following: organomineral black earth - brownised black earth; organomineral black earth - brownised black earth - typical brown soil; typical brown soil - illimerised soil Typical brown soil is formed on argilloschists and it occurs in two forms: medium deep, medium skeletal acid brown soil and deep, poorly skeletal acid brown soil The most productive sites of the montane beech forest on Brezovica are deep acid brown soils and the soil combination: typical brown soil - illimerised soil on limestone.
