Genesis and characteristics of the soil in A-R stage in forest ecosystems of NP 'Tara'
KneeviMilan,Ko?anin Olivera
Glasnik ?umarskog Fakulteta , 2009, DOI: 10.2298/gsf0999075k
Abstract: Different types of soil in A-R stage formed on limestone and serpentinite in forest ecosystems in NP 'Tara' were researched. Based on the specific effect of limestone on the soil genesis and evolution, two types of calcareous limestone bedrocks were distinguished: dense limestones, and soft, marly limestones. Three subtypes of black earth were studied on dense limestones. They are: organogenic, organo-mineral and brownised soils. One soil type was researched on soft, marly limestones: rendzina, the leached variety. One soil type was researched on serpentinites, within the A-R stage: humus-siliceous soil (ranker), subtype eutric ranker. This paper also presents the evaluation of ecological and productive characteristics of the study soils. If the soil is observed separately, regardless of the tree species growing on it, the soils in A-R stage in NP 'Tara' cannot be evaluated as highly productive. However, in all plant communities on the soils in A-R stage on limestone, the values of average volume, current volume increment, and basal area were high. The unfavourable physical characteristics of the soil in the area of NP 'Tara' are compensated by the effect of humid climate. On the study eutric humus siliceous soils in the area of NP 'Tara', in the natural and artificially established stands of Scots pine and Austrian pine, the ecological and productive value is conditioned by numerous factors and it is mainly limited by unfavourable physical characteristics. Regardless of the unfavourable ecological and productive characteristics of the soil, the natural and artificially established stands of Scots pine and Austrian pine are in the coeno-ecological optimum.
Rendzinas in the community of beech, fir and spruce with Scots pine in NP 'Tara'
KneeviMilan,Ko?anin Olivera
Glasnik ?umarskog Fakulteta , 2010, DOI: 10.2298/gsf1001101k
Abstract: The rendzinas were studied in the community of beech, fir and spruce with Scots pine (Piceo-Fago-Abietetum subass. pinetosum silvestris), at the altitudes above 1,000 m, on steep slopes and warm aspects. The genesis and properties of these rendzinas were strongly affected by chemical composition, mineralogical structure and bedrock weathering. Soft limestones, which are characterized by low hardness and a higher content of insoluble residue, present the major impact on the physical and chemical characteristics of rendzinas. The presence of active carbonates in the profile causes a neutral to weak alkaline reaction, provides the constant buffering of organic acids and the formation of Ca-humates, and in this way also the formation of a stable organic-mineral complex, which in turn results in the formation of stable grainy soil structure.
Characteristics of acric luvisol on Magle limestones
KneeviMilan,Ko?anin Olivera
Glasnik ?umarskog Fakulteta , 2006, DOI: 10.2298/gsf0693097k
Abstract: Very deep soils with clearly differentiated two-layered profile physiography were studied on the limestones of the mountain Magle . The very marked morphological differentiation of the profile is followed by significant textural differences and the variation of chemical characteristics of the soils. The profiles are 80-140 cm deep. The topsoil part of the solum, yellow-brown in colour, is 30-90 cm deep. Its textural class is silty-clay loam. Its chemical characteristics are very acid reaction and very low degree of base saturation. The relic (B) horizon is reddish brown in colour, and it is characterized by a very high percentage of the colloidal clay, it is highly plastic and it has a compact structure. Its reaction is mostly weak acid to neutral, and the degree of base saturation is very high. The study results confirm the hypothesis of a very high impact of the Aeolian process on the formation of deep two-layered profiles on Magle limestones.

Glasnik ?umarskog Fakulteta , 2005, DOI: 10.2298/gsf0592087k
Abstract: The soils in sessile oak forests were studied at three localities in the region of Northeast Serbia. Brownised dystrict humus-siliceous soil was studied on gneiss in M.U. "Zlatica" - N.P. " erdap", in the forest of sessile oak with fescue grass (Quercetum montanum subass. festucetosum heterophyllae). Dystric acid brown soil on gneiss was studied in the region of F.E. "Severni Ku aj", M.U. "Ravna Reka", in the community of sessile oak and hornbeam (Querco-Carpinetum moesiacum), and in the region of the Teaching Base "Majdanpe ka Domena" in M.U. "Crna Reka - Pek", in the forest of sessile oak with hairy sedge (Quercetum montanum subass. caricetosum pilosae) on schist's. Eutric brown soil was studied on amphibolite schist and on basic and neutral eruptive rocks in the region of N.P. " erdap", in M.U. "Zlatica", in the typical sessile oak forest (Quercetum montanum subass. tipicum).

Ko?anin Olivera,KneeviMilan
Glasnik ?umarskog Fakulteta , 2003, DOI: 10.2298/gsf0387151k
Abstract: Cambic soils were studied in the mountainous beech forest (Fagetum moesiacae montanum, Jov. 1976) (Tomi , 1992) in the region of the mountainous massif Crni Vrh near Bor. The soils were researched in two sample plots. The study soils were formed on andesite rocks in the monodominant community of beech and now they are under a strong impact of acid deposition pollutants which reach the zone of Crni Vrh from RTB Bor.

KneeviMilan,Ko?anin Olivera
Glasnik ?umarskog Fakulteta , 2002, DOI: 10.2298/gsf0286135k
Abstract: The study deals with the soils in the montane beech forest (Fagetum moesiacae montanum Jov. 53) in the management units "Ju ni Kuèaj 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.

Glasnik ?umarskog Fakulteta , 2011, DOI: 10.2298/gsf1104071k
Abstract: The paper presents a statistical analysis of the basic chemical characteristics of dystric cambisol, its depth and clay content in Posavsko forest economic district. The aim was to define the influence of pedogenetic factors (primarily parent rock) on the characteristics of dystric cambisols, using statistical analysis. The analysis was based on the data from the Interpreter of Soil and Typological Maps of Posavsko forest economic district. 35 soil profiles were analyzed. A and (B) horizons were analyzed separately, then compared with each other in terms of similarities and differences. Variability is greater in the A horizon. The values of variability, analysis of variance, linear and multiple regression, correlation and cluster analysis were determined. Three main subtypes were defined based on the results of chemical characteristics, depth, and clay content, namely: leached (4 profiles), humus (1 profile) and typical (30 profiles). The results show that the properties of this soil type are significantly influenced by the character of parent material.
Production potential of the soil and the basic elements of productivity of the most widely spred sessil types in the u. N.P. erdap”
KneeviMilan,Milo?evi? Rajko,Ko?anin Olivera
Glasnik ?umarskog Fakulteta , 2010, DOI: 10.2298/gsf1002057k
Abstract: This paper is on the results of the soil and its production potential in the types of forests of sessile oaks (Quercus petraea) in the area of the National Park erdap” in the community units of Zlatica, erdap, trba ko korito, Desna reka and Ko ica. There are the most widely spread types of the sprout forests of the sessile oaks in the research area, deep deluvium, luvisoil, eutric cambsoils, and a great number of subtypes of acid brown soil. Considering the fact that the production potential of the defined types of soil depends on the depth, skeleton and other physical characteristics which determine acception, keeping and moving of water and this means that the production value of the studied soils is in the direct correlation with physical-geographical conditions of the environment. Taking into account that solum is well developed and the low contents of skeleton, all the studied soil in the most widely spread types of sessile oaks in the area of N.P. erdap”, are very productive natural habitats. The exception is acid brown soil, which characteristics vary as well as their production potential. Apart from a good production potential of the studied soils within this paper, sessile forests in the researched areas irrationally use production potential of the habitat. In the research area in the last 20 years, the processes of devitalizing and the appearance of decaying of sessile oaks are expressed. In the sessile forests of Serbia, there are forests of the production and protection character, and the structure of the sessile forests at global level is characterized by not normal state with domination of middle aged and in great extent mature withering ingredients, what is the main cause of insufficiently used good potential of the soil.
Assessment of production potential of podzolised and typical acid brown soils in some forest types in the area of Veliki Jastrebac
KneeviMilan,Ko?anin Olivera,Milo?evi? Rajko
Glasnik ?umarskog Fakulteta , 2011, DOI: 10.2298/gsf1103057k
Abstract: The characteristics of podzolised and typical acid brown soils were studied in beech forests in Management Unit “Lomni ka Reka“ on Veliki Jastrebac. Also, their production potential was evaluated based on their physico-chemical properties. As productivity is a realised value of the soil fertility, realized through the yield and increment, the site productive capacity was evaluated based on mean maximal heights. The correlation analysis shows the extent to which the characteristics of podzolised and typical acid brown soils affect the mean maximal heights.
