CHARACTERISTICS OF THE SOILS OF BEACH AND OAK STANDS
IN PSUNJ MOUNTAIN


Summary


In his investigations in mountain, hilly and foothill regions of the Psunj Mountain
covered with Beech stands (Fagetum croaticum Horv.) or Pedunculate Oak/
/Hornbeam stands (Querco-carpinetum croaticum Horv.) the author examined numerous
profiles of soils developed on intrusive, metamorphic and sedimentary rocks.
In the paper are included the characteristics of soils of Beech and Oak forests in
Psunj Mountain, developed on intrusive and metamorphic rocks, because they cover
there the largest areas.


The investigations showed that the dominant soil type — on quartzites, gneiss,
gneissoid granites, amphibolites, quartzitic-sericitic phyllites, slate, mica schists and
other silicate rocks in Psunj Mountain — is acid brown soil (dystric cambisol).


In the developmental series of soils, in addition to the brown acid soils, there
were established rankers , as well as on small areas — mainly of upper regions


— soil stages making transitions between these and brown podzolic soils.
The profile structure of acid brown soils in Psunj Mountain is:
A-(B)-(B)Ci-C, also A-(B)Ci-CiC, and A-A(B)-(B)-(B)Ci-C.
The ranker s in Psunj Mountain are of a distinctly lithogenic nature and
most frequently of the A^C, the A-AO-C or the »brownized« (»verbraunter Ranker«)
A-(B)Ci-C profile structure.
The stage of soil in Psunj Mountain which according to its properties partly
differs from acid brown soils (dystric cambisol), the author designated as the
»humus variant of acid brown soils« (humic cambisol). Described was
also a stage of soil related to brown podzolic soils. Under the acidophilus forest of
montane Beech on quarzite-muscovite schists in Psunj Mountain the most frequent
profile structure of the humus variant is the Aoo-AoAi-A(B)Ci-C.
The basic characteristics of the soils on silicate rocks in Psunj Mountain are
markedly acid reaction and a low degree of saturation with bases, i. e. the properties
characteristic of the acid quartz-silicate character of these rocks.
