Influence of some soil characteristics on the productivity of stands in Dragomirna plateau, Suceava county, Romania

The interdependence between ecological factors of the forest site rock-soil has a large variability in the case of Dragomirna plateau (because of the geology of the area) and occurs in various situations of site quality. As an consequence of this diversity, some of the soil properties represent a larger influence on the biometrical characteristics of the stands, implicitly on their productivity. Starting on the premise that not all the tree species present on the area have the same edaphic ecological exigences and the fact that the common beech, the main species in the analized tree stands is in a suboptimal climate (Stănescu 1979), was considered to be useful to determine wich of the soil conditions studied, influence more the productivity of the main species from the Dragomirna plateau.
