POTENTIAL PRODUCTION OF SOILS IN THE FOREST CULTURES
OF THE REGION OF BOSILJEVO
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.
