AB  - Soil degradation is a global problem and researchers are facing the challenge of assessing the scale, trends, and consequences of contributing processes. With this in mind, this study implemented the new concept of multiple soil degradation indices (MSDI) for the first time in the region of Sumadija and Western Serbia (SWS). This concept enables the simultaneous integration of several environmental components that can act separately or synergistically and offers concrete answers and information on the state and distribution of physical (PSDI), chemical (CSDI) and biological (BSDI) soil degradation. Using several different geospatial-modelled approaches, results indicated that physical degradation was the greatest contributor to soil degradation in the SWS region with an impact of 55%, followed by chemical degradation at 16%, while biological degradation only had a 6% impact. The dominant indicator of physical degradation was the vegetation cover management factor with an impact of approximately 58%, while for chemical degradation it was soil organic matter, with a relative impact of almost 49%. Total microflora and total number of fungi were the most significant biological indicators with an average impact of approximately 43%. In addition, this study indicated that about 59% of the region is currently degraded, with about 44% of it classified as moderately degraded. The results of this study offer new insights into the geospatial dynamics of interactive degradation processes in Serbia and can form the basis for strengthening scientific, expert, and political support when implementing international and national policies concerned with protecting soil from degradation.

AB  - This paper aims to improve the methodology and results accuracy of MEDALUS model for assessing land degradation sensitivity through the application of different data detail levels and by introducing the application of Ellenberg indices in metrics related to vegetation drought sensitivity assessment. For that purpose, the MEDALUS model was applied at 2 levels of detail. Level I (municipality level) implied the use of available large-scale databases and level II (watershed) contains more detailed information about vegetation used in the calculation of the VQI and MQI factors (Fig. S6). The comparison was made using data based on CORINE Land Cover (2012) and forest inventory data, complemented with object-based classification. Results showed that data based on forest inventory data with the application of Ellenberg's indices and object-based classification have one class more, critical (C1 and C2) and that the percentage distribution of classes is different in both quantitative (area size of class sensitivity) and qualitative (aggregation and dispersion of sensitivity classes). The use of data from Forest Management Plans and the application of Ellenberg's indices affect the quality of the results and find its application in the model, especially if these results are used for monitoring and land area management on fine scales. Remote sensed data images (Sentinel-2B) were introduced into the methodology as a very important environmental monitoring tool and model results validation.

AB  - Travnjaci igraju značajnu ulogu u globalnom kruženju ugljenika, a rezerve ugljenika u travnim ekosistemima su pod uticajem ljudskih aktivnosti i prirodnih poremećaja. Cilj ovog proučavanja je da se odrede razlike u rezervama ugljenika u travnim ekosistemima na dva ogledna lokaliteta na područjima Stare planine i Zlatara (Srbija). Proučavana područja su pod prirodnim planinskim travnjacima iste zajednice (Agrostietum capillaris Pavl. 1955) i dva tipa zemljišta (Umbric Leptosol (Dystric)) i (Haplic Cambisol (Dystric)), ali sa različitim intenzitetom ispaše. Uzorkovana je nadzemna i podzemna biomasa, a zemljište po fiksnim dubinama 0-10, 10-20 i 20-40 cm. Procena rezerve ugljenika i stopa akumulacije određene su metodom Tier 2 IPCC (2003). Potencijalno mineralizujući ugljenik određen je primenom procedure sekvencijalne inkubacije u laboratorijskim uslovima. Prema dobijenim rezultatima, veća količina padavina na oglednom području na Staroj planini rezultirala je većom akumulacijom nadzemne biomase, koja je bila izložena većoj dekompoziciji in situ pokazujući tako manju količinu potencijalno mineralizujućeg ugljenika (PMC) in vitro. Takođe, količina PMC na oba lokaliteta ukazuje da je mineralizacija organske materije u zemljištu pod većim uticajem faktora vezanih za svojstva zemljišta, klimatske uslove i ispašu.
AB  - Grasslands are a major player in the global carbon cycle, although carbon stocks in grasslands are influenced by human activities and natural disturbances. The aim of this study is to determine differences in carbon stock on two test areas of grassland ecosystem in the highlands of Stara Planina and Zlatar Mountains (Serbia). The investigated sites are natural mountain grasslands of the same vegetation community (Agrostietum capillarisPavl. 1955) and soil type (Umbric Leptosol (Dystric) and Haplic Cambisol (Dystric)), but with different grazing intensity. Aboveground and belowground biomasses were measured in each sample plot, and soil was sampled at fixed depths of 0-10, 10-20 and 20-40 cm. The estimation of C stock and the rate of soil C accumulation were determined by the Tier 2 method IPCC (2003). Carbon mineralization potentials were determined via sequential incubation procedure in the laboratory conditions. According to the obtained results, the greater amount of precipitation on Mt. Stara Planina resulted in a greater accumulation of aboveground biomass, which was subjected to a greater decomposition in situ, thus showing a lower amount of PMC in vitro. In addition, potentially mineralizable carbon (PMC) among the sample plots from both sites indicates that the mineralization of soil organic matter was more influenced by the factors related to the soil characteristics, climatic conditions and grazing.

AB  - In this paper, the assessment of the sensitivity of the soil in the rural area of Cukarica municipality to the processes of degradation is considered. Land areas, especially in the vicinity of large cities, are exposed to numerous processes of degradation: soil erosion, urban and industrial zone expansion at the expense of fertile agricultural soils, activation of landslides and a number of other significant ecological problems. Based on the characteristics of the research area, the MEDALUS (Mediterranean Desertification and Land Use) model was applied, and for the assessment of sensitivity to the processes of degradation the main quality indicators were considered: soil, climate, vegetation and management. For each of the analyzed quality indicators, parameter groups were identified. Each parameter is quantified according to the defined method by giving them a sensitivity coefficient between 1.0 and 2.0. ArcGIS 10.0 has been applied to analyze and prepare layers of quality maps. Subsequently, the geometric mean for all four quality indicators was used to generate the map of environmental sensitivity to degradation. The results obtained show that 41.54% of the study area is classified as critical; 22.34% of the surface as fragile; 8.47% of the areas are potentially endangered and 9.58% not threatened to degradation processes. The results have also shown that MEDALUS model is a functional tool for simulations which support sustainable land management in the areas prone to degradation.

AB  - In urban areas, the presence of toxic microelements in the environment due to the anthropogenic impact (primarily of traffic) poses a serious problem. The negative impact of pollution on populated urban areas is particularly manifest in children. To establish the level of microelement pollution, at 40 localities in the municipality of Stari grad in Belgrade we sampled surface soil near kindergartens and schools during 2013. By applying remote sensing and GIS, small green areas were selected and the spatial distribution of microelements was determined. Because of their different origins and anthropogenic impact, three heavy metals, Cd, Ni and Zn, were examined; the level of soil pollution was assessed by determining their total content, pollution index (Pi), enrichment factor (EF), single risk factor (Ei) and ecological risk index (RI). The highest concentration established was that of Zn, with a mean value of 223.11 mg/kg. The Pi values for Zn (2.96) and Cd (2.98) were similar. Due to the prevailing geological substrate, Ni had the lowest EF (0.75) and Ei (3.09). The effect of the geological substrate on the Ni content was also confirmed by its very high concentration along the banks of the rivers Sava and Danube, while the total contents and factors for Cd and Zn indicated that they were concentrated in the city center. Our results show that 30.72% of the green areas in the city center have a moderate RI, which indicates that the examined pollutants do not present a danger to children.

AB  - This paper studies the assessment of sensitivity to land degradation of Deliblato sands (the northern part of Serbia), as a special nature reserve. Sandy soils of Deliblato sands are highly sensitive to degradation (given their fragility), while the system of land use is regulated according to the law, consisting of three zones under protection. Based on the MEDALUS approach and the characteristics of the study area, four main factors were considered for evaluation: soil, climate, vegetation and management. Several indicators affecting the quality of each factor were identified. Each indicator was quantified according to its quality and given a weighting of between 1.0 and 2.0. ArcGIS 9 was utilized to analyze and prepare the layers of quality maps, using the geometric mean to integrate the individual indicator map. In turn, the geometric mean of all four quality indices was used to generate sensitivity of land degradation status map. Results showed that 56.26% of the area is classified as critical; 43.18% as fragile; 0.55% as potentially affected and 0.01% as not affected by degradation. The values of vegetation quality index, expressed as coverage, diversity of vegetation functions and management policy during the protection regime are clearly represented through correlation coefficient (0.87 and 0.47).

AB  - Acidification, as a form of soil degradation is a process that leads to permanent reduction in the quality of soil as the most important natural resource. The process of soil acidification, which in the first place implies a reduction in soil pH, can be caused by natural processes, but also considerably accelerated by the anthropogenic influence of excessive S and N emissions, uncontrolled deforestation, and intensive agricultural processes. Critical loads, i.e. the upper limit of harmful depositions (primarily of S and N) which will not cause damages to the ecosystem, were determined in Europe under the auspices of the Executive Committee of the CLRTAP in 1980. These values represent the basic indicators of ecosystem stability to the process of acidification. This paper defines the status of acidification for the period up to 2100 in relation to the long term critical and target loading of soil with S and N on the territory of Krupanj municipality by applying the VSD model. The Inverse Distance Weighting (IDW) geostatistic module was used as the interpolation method. Land management, particularly in areas susceptible to acidification, needs to be focused on well-balanced agriculture and use of crops/seedlings to achieve the optimum land use and sustainable productivity for the projected 100-year period.

AB  - The paper shows spatial estimation of soil loss applying USLE equation in the area of Kolubara district. Apart from the erosion factor and vegetative cover factor, soil erodibility (K factor) is a key parameter for soil erosion modelling. The erodibility factor in the area of Kolubara district was calculated using the Wishmaier and Smith method. The land in the study area is mainly used for agriculture and C factor was determined by Corine Land Cover 2000. The objective of this study was to assess the applicability of a simple methodology, based on the application of USLE model, to determine the erosion intensity of certain soil types. In the area of Kolubara district the most common soil category is the one not threatened by water erosion covering 53.9% of the total territory. 15.6% is low threatened, 14.7 % moderately threatened, 9.51% is highly threaten and very high threatened is 6.23% of the total territory. Compared to the area they cover, extremely endangered soils are Haplic Cambisol (Dystric), Haplic Cambisol (Eutric, Skeletic) and Haplic Cambisol (Eutric). Low and very low erosion category in the study area were noted in previous researches and the tendency of erosion reduction resulted from the change in land use, i.e. abandoning large agricultural areas.

AB  - This paper aims at assessment of soil erosion potential and its spatial distribution on the 1235 km(2) area of municipality Pirot located in south-eastern Serbia. The study was conducted by using well-known Universal Soil Loss Equation (USLE) model due to its modest data demand and transparent structure. The erosion factors of USLE were collected and processed through a GIS-based approach offering ease of elaboration and manipulation of erosive factors. All the erosive factors were determined on a 30 x 30 m cell basis and multiplied in order to obtain the map of potential average annual soil erosion. The average annual soil loss was estimated at 8.65 tha(-1)yr(-1) classifying the area of Pirot municipality under low erosion rate category. More than 80% of the municipality area was characterized by insignificant ( lt  3 tha(-1)yr(-1)), and low erosion category (3-10 tha(-1)yr(-1)). Around 7.8% of the area was found to be under moderate erosion category (10-20 tha(-1)yr(-1)). High erosion category was found on 6.8% of the area (20-40 tha(-1) yr(-1)), while there is around 5.2% of the area under very high erosion category ( gt 40 tha(-1)yr(-1)). It means that almost 15000 ha of the area of Pirot municipality are facing high and very high erosion. The analysis of vertical distribution of erosion processes pointed out that the zone between 500 and 800 m a.s.l suffers more from erosion than other elevation zones mainly due to land management. The results of this work are in agreement with the soil erosion map of Serbia, the sediment yield measurements in the basin and with other, more detailed, studies in the municipality. Therefore, the presented methodology could be applied as a framework for the evaluation of erosive factors on soil resources in Serbia when limited data are available. The outputs of these studies can be used for the identification of vulnerable areas on a cell-basis and for programming of protection measures.

AB  - Sadržaj organskog ugljenika u zemljištima planinskih oblasti je veoma heterogen, što je uglavnom rezultat varijabilnosti zemljišne sredine i mikroklime u lokalnim razmerama. Cilj ovog istraživanja je određivanje gustine zemljišnog organskog ugljenika (SOCD) i njegovog sadržaja u leptosolu na morenskim nanosima pod travnjacima koji se nalaze na visokoj nadmorskoj visini jezerske površi u Nacionalnom parku 'Durmitor' u Crnoj Gori, kao i definisanje varijabli zemljišta koje se mogu koristiti kao faktori za određivanje gustine zemljišnog organskog ugljenika (SOCD) na 28 zemljišnih profila. Naši rezultati ukazuju na to da je sadržaj zemljišnog organskog uglljenika (SOC) u prvih 40 cm alpskih pašnjaka procenjen na 560 414,86 t C, ili 152,66 t·ha-1, sa prosečnom gustinom od 15,27 kg·m-2. Gustina zemljišnog organskog ugljenika značajno se povećala sa porastom vlažnosti zemljišta, povećanjem sadržaja gline i praha, i samo umereno sa porastom srednje godišnje temperature. Ove promenljive u kombinaciji daju objašnjenje za oko 51% ukupne varijacije gustine zemljišnog organskog ugljenika (SOC).
AB  - Soil organic C storage in mountain areas is highly heterogeneous, mainly as a result of local-scale variability in the soil environment and microclimate. The aims of the present study were to estimate soil organic carbon density (SOCD) and stocks in leptosol on morainic deposits of high-altitude grasslands of the Lake Plateau of Mt. Durmitor National Park in Montenegro, and determine the soil variables that can be used as factors to determine the SOCD at 28 soil profiles. Our results indicated that SOC storage in the top 40 cm of the alpine grasslands were estimated at 560 414.86 t C, or 152.66 t·ha-1, with an average density of 15.27 kg·m-2. The soil organic carbon density increased significantly with soil moisture, clay and silt content, but only moderately with mean annual temperature. In conjunction, these variables could explain approximately 51% of the total variation in SOC density.

abstract = "Sadržaj organskog ugljenika u zemljištima planinskih oblasti je veoma heterogen, što je uglavnom rezultat varijabilnosti zemljišne sredine i mikroklime u lokalnim razmerama. Cilj ovog istraživanja je određivanje gustine zemljišnog organskog ugljenika (SOCD) i njegovog sadržaja u leptosolu na morenskim nanosima pod travnjacima koji se nalaze na visokoj nadmorskoj visini jezerske površi u Nacionalnom parku 'Durmitor' u Crnoj Gori, kao i definisanje varijabli zemljišta koje se mogu koristiti kao faktori za određivanje gustine zemljišnog organskog ugljenika (SOCD) na 28 zemljišnih profila. Naši rezultati ukazuju na to da je sadržaj zemljišnog organskog uglljenika (SOC) u prvih 40 cm alpskih pašnjaka procenjen na 560 414,86 t C, ili 152,66 t·ha-1, sa prosečnom gustinom od 15,27 kg·m-2. Gustina zemljišnog organskog ugljenika značajno se povećala sa porastom vlažnosti zemljišta, povećanjem sadržaja gline i praha, i samo umereno sa porastom srednje godišnje temperature. Ove promenljive u kombinaciji daju objašnjenje za oko 51% ukupne varijacije gustine zemljišnog organskog ugljenika (SOC)., Soil organic C storage in mountain areas is highly heterogeneous, mainly as a result of local-scale variability in the soil environment and microclimate. The aims of the present study were to estimate soil organic carbon density (SOCD) and stocks in leptosol on morainic deposits of high-altitude grasslands of the Lake Plateau of Mt. Durmitor National Park in Montenegro, and determine the soil variables that can be used as factors to determine the SOCD at 28 soil profiles. Our results indicated that SOC storage in the top 40 cm of the alpine grasslands were estimated at 560 414.86 t C, or 152.66 t·ha-1, with an average density of 15.27 kg·m-2.

AB  - U ovom radu proučavanja su imala za cilj bolje razumevanje veze između svojstava zemljišta i pristupačnosti mikroelemenata u zemljištu pod pašnjacima. Proučavanja su vršena na lokalitetima Stare planine (Babin zub, Javor I, Javor II, i Prelesje) gde je dominantan tip zemljišta kiselo humusno-silikatno zemljište (Dystricleptosol), a na kojima se pojavljuje zajednica Agrostietumvulgaris (capillaris) Z. Pavl. 1955. Na svim lokalitetima zemljište je uzorkovano na fiksnim dubinama: 0-5, 5-10, 10 -20 i 20 - 40 cm. Pseudoukupni (ekstrakt rastvor aquaregia) sadržaji mikroelementa (Pb, Cd, Cu i Zn), kao i pristupačni sadržaji (ekstrakt DTPA helatnog agensa) u zemljištu mereni su AAS. Sadržaji pseudoukupnih mikroelemenata u proučavanom zemljištu su niži ili u granicama za multifunkcionalno korišćenje zemljišta. Utvrđena je veza između sadržaja pristupačnih mikroelemenata u zemljištu i sadržaja pseudoukupnih mikroelemenata, kao i njihova korelacija ovih sadržaja sa svojstvima proučavanih zemljišta.
AB  - The research presented in this paper was aimed at better understanding of the relationship between soil properties and the availability of trace elements in pasture soils. The research was conducted in several localities of Stara Planina mountain (Babin zub, Javor I, Javor II and Prelesje), where the dominant soil type is acid humus siliceous soil (Dystric leptosol) characterized by the presence of the Agrostietumvulgaris (capillaris) community Z. Pavl., 1955. In all localities the soil sampling was performed at fixed depths of 0-5, 5-10, 10 -20 and 20 - 40 cm. The pseudo-total contents of trace elements (Pb, Cd, Cu and Zn) (extracted with aqua regia solution), as well as the available contents (extracted with the DTPA chelating agent) in the soil were measured by AAS. The pseudo- total content of trace elements in the soil studied are lower or within the limits for multifunctional land use. A correlation was established between the content of available trace elements in soil and the content of pseudo-total trace elements, as well as between these contents and the properties of the soils studied.
