POTENTIAL PRODUCTION OF SOILS IN THE FOREST CULTURES OF THE REGION OF BOSILJEVO Summary The forest cultures in the area of Bosiljevo represent one of the most interesting and largest conifer plantings (350 ha) in Croatia. They are situated 23 km. southwest of Karlovac, in the central part of the climazonal area of Pedunculate Oak and Hornbeam (Querco-Carpinetum Horv.), and were established on the heathland (Genisto- Callunetum croaticum Horv.). The parent rock consists of Cretaceous limestones. The climate is perhumid (Tab. 1). The altitude of the region ranges from 230 to 250 m. On the basis of the pedological investigations and the presented physiographic properties (Tabl. 2 and 3), the investigated soils were designated as acid brown soils lying on »terra rossa« (described in more detail under ihe name of »podzolized brown heath soil«, by M. Gračanin, 1951), and assessed from the standpoint of modern wood production to possess a high production potential.. By comparing the increment of Norway Spruce (Picea abies (L.) Karst) with that of Scots Pine (Pinus silvestris L.) on these soils (Tab. 1) the conclusion was drawn that the natural production potential of acid brown soils on the relict »terra rossa« in the mentioned locality is by 25% better utilized when growing Norway Spruce than Scots Pine. |
