AB  - The paper presents the results of research on the content of accessible forms of Ni and Cr in the ranker-type soils that are formed on the serpentinites massifs in Serbia. Soil samples were taken from seven 
different locations across Serbia (Zlatibor mountain, Kopaonik mountain, Miroč, Maljen mountain, 
Bukovi, Suvobor and Bubanj Potok) at the altitude range between 100 and 1700 m. There were 
analyzed 46 soil samples in total. The concentration of accessible forms of Ni and Cr was determined 
by extraction in a solution of DTPA-TEA (pH 7.3, ratio soil and solution = 1:2) by optical emission 
spectroscopy with induced coupled plasma (ICP-OES).
The content of accessible Ni in the all examined soil samples of ranker-type soils varies from 68 - 920 
mg/kg, while the most common results (about 70% of the total number of samples) vary from 200 -
600 mg/kg. The content of accessible Cr in all examined soils varies from 16 - 216 mg/kg. The content 
of both, Ni and Cr significantly exceeds the value limits in soils. 
The results of the analysis of all soil samples of ranker-type soils refer to high concentration of 
accessible Ni and Cr and thus correspond to phytotoxic concentrations.
Given the fact that there are no anthropogenic sources of pollution nearby the investigation locations, 
it can be concluded that such a high concentration of accessible Ni and Cr in the ranker-type soils, that 
were formed on serpentinites massifs under the various pedogenetic conditions, is of geochemical 
origin. The geochemical distribution of Ni and Cr places this type of soil in the group of lithogenic soils.

AB  - UVOD i CILjEVI: Sadržaja organske materije (OM) u zemljištu je bitan faktor pri odabiru
loznih podloga i sorti vinove loze pošto značajno utiče na vegetativni porast i prinos, koji su u
proizvodnji vina kontrolisani, tako da je važno precizno odrediti sadržaj OM pri podizanju i
eksploataciji zasada vinove loze. Cilj ovog istraživanja jeste precizno i prostorno predstavljanje
sadržaja OM u rendzinama na području Krnjevačkog vinogorja. Rendzina je jedno od najpogodnijih
vinogradarskih zemljišta kod nas. Prema zvaničnom sistemu klasifikacije zemljišta Srbije,
rendzina je tip zemljišta sa A – AC – C – R profilom, razvijen na matičnoj steni koja sadrži
više od 20% krečnjačkog materijala (osim zemljišta sa A – R profilom na tvrdom čistom
krečnjaku ili dolomitu). U Svetskoj referentnoj bazi za zemljišne resurse (WRB) rendzine
odgovaraju uglavnom renzičnim leptosolima (Rendzic Leptosols) ili faozemima (Phaeozems).
MATERIJAL i METOD: Krnjevačko vinogorje je deo Šumadijskog vinogradarskog rejona, nalazi
se na brežuljkastim padinama i kosama zapadno od Velike Morave, a severno od Smederevske
Palanke i Velike Plane, prostire se na površini od 11188,22 ha. Istraživanje je sprovedeno u
vinogradu Podruma Radovanović (44°25ʹ57,60ʺ SGŠ; 21°02ʹ40,34ʺ IGD i 44°25ʹ 41,33ʺ SGŠ;
21°02ʹ51,29ʺ IGD), na pet parcela zasađenih različitim sortama vinove loze gde je otvoreno i
opisano 15 pedoloških profila. Uzorci u narušenom stanju su uzeti iz svih genetskih horizonata
od površine do matične stene. Sadržaj organskog ugljenika (OC) određen je dihromatnom metodom
u 54 uzorka zemljišta, a sadržaj OM je proračunat prema formuli OM = OC x 1,72. Prostorni
prikaz sadržaja OM u ispitivanim zemljištima urađen je korišćenjem programa ArcGis 10.0.
REZULTATI i ZAKLjUČCI: Na ispitivanom lokalitetu identifikovana su tri varijeteta
rendzine: karbonatana rendzina, rendzina u ogajnjačavanju i izlužena rendzina. Sadržaj OM u
humusnom horizontu rendzina varirao je u opsegu od 1,18% do 4,17%, sa prosečno vrednošću od
2,55 ± 0,56%. Zemljišta ispitivanog područja su slabo i srednje humusna, što je povoljno s
obzirom na to da se najbolji vinogradraski i vinarski rezultati dobijaju na srednje plodnim
zemljištima koja imaju neka pedološka ograničenja. Idealno vinogradarsko zemljište sadrži 2–
4% OM. Sadržaj OM se pravilno smanjivao po dubini profila, tako da je u C horizontu iznosio od
0,67% do 1,04%, a prosečna vrednost je bila 0,97 ± 0,21%. Relativno visok sadržaj OM u C
horizontu je posledica dubokog prodiranja korenovog sistema vinove loze. Na tematskoj karti koja
prostorno prikazuje sadržaj OM u površinskom horizontu može se uočiti da je najviši sadržaj
OM u zoni gde se vinograd graniči sa šumom, što dovodi do zaključka da je u ovom delu izraženije
nakupljanje OM (u odnosu na preostalu ispitivanu površinu), verovatno kao posledica prirodnog
unošenja organskih ostataka šumske vegetacije. Na osnovu rezultat studije može se zaključiti da
su ispitivana zemljišta prema sadržaju OM pogodna za uzgoj vinove loze. Prostorni prikaz
sadržaja OM omogućava izdvajanje određenih površina za dalje analize kvaliteta grožđa i vina.

AB  - The impact of various types of uses of Pseudogley soils in southern Mačva and Pocerina on
theiraggregate distributionand stability was studied on soil samples collected from profiles under
forest, meadow and arable land, at three localities. The aggregate composition and stability were
determined by Savinov’smethod. The soil structure was assessed by using Revut’s coefficient of soil
structure (Ks) and Vershinin’s coefficient of soil aggregate structure (KA). The results show that the
studied Pseudogley soils are characterized by an unfavorable structure, while the type of land use has
a significant impact on the aggregate composition and stability, especially in surface Ah and Ahp
horizons, where these differences are the most pronounced. The most favorable aggregate
composition and highest wet-stability are found in Pseudogley profiles under forest vegetation. The
aggregate distribution of meadow profiles was intermediate and of arable land the poorest. Statistical
analysis of the collected data shows that Ks values, determined by dry sieving, were the highest in
forest profiles (2.261.21 on average), while the values for meadow were 1.591.09 and of arable
land 1.140.62. The values of KA, used to assess the aggregate stability to water, also show that forest
Pseudogleys have the highest average values (2.051.03), followed by meadow (1.96 0.99) and
cultivated soils (1.931.22). The results of correlation analysis indicate that Ks is negatively
correlated with clay, pH value and base saturation, but positively correlated with soil humus (r=-0.77,
-0.70, -0.81 and 0.79, respectively, p<0.01). Conversely, KA is negatively correlated with humus and
positively correlated with clay, pH value and base saturation (r=-0.21, 0.82, 0.69 and 0.69,
respectively, p<0.01).

AB  - This study collected agricultural surface soil samples from 200 sites in the district of Braničevo, located in the Carpathian Mountains – Pannonian Basin south of the Danube River (Serbia). The main objective was to determine the soil contamination by ten potentially toxic elements (As, B, Cd, Cr, Cu, Mn, Mo, Ni, Pb, Zn) and evaluate the associated ecological risk via different indices. The physicochemical parameters, pH, organic carbon, water content, and soil texture were also analyzed. The mean values of most metal concentrations remained below their corresponding national target values, except for Mo and Ni. The main soil texture types were silt loam (40.5 %) and silty clay loam (34.5 %). According to the mean values, pollution load index (PLI) and potential ecological risk (RI) demonstrated that the soil in the study area was exposed to moderate pollution and moderate ecological risk, while enrichment factor (EF), geoaccumulation index (Igeo), and contamination factor (CF) revealed very high enrichment and contamination with Mo, implying the impact of anthropogenic activities. There was a lack of strong correlations among elements and soil properties, except for Cd and Corg, while moderate to strong positive inter-metal relationships suggested their common sources. The chemometric analysis illustrated the classification of sampling sites into two distinct clusters of spatial similarities according to higher and lower metal concentrations. Geospatial mapping identified a few areas of considerable ecological risk. © 2022,Carpathian Journal of Earth and Environmental Sciences. All Rights Reserved.

AB  - National soil classification system (NSCS) used in Serbia is based on the principles of genetic classification. It is utilizes the concept of genetic soil horizons. The world reference base (WRB) for soil resources is based on soil properties defined in terms of diagnostic horizons, diagnostic properties, and diagnostic materials, which to the greatest extent possible should be measurable and observable in the field. The difference between genetic vs. diagnostic horizons creates an obstacle in correlation of soil types from NSCS with reference soil groups (RSG's) of WRB for soil resources, whereas the advantage in this work is that most of the soil names of national system correlate to the revised legend of the Soil Map of the World which is an forerunner of WRB for soil resources.
This work aims to compare Ranker soil type of NSCS with corresponding RSG from WRB for soil resources, namely with Leptosols, as they have been reported in Serbia and abroad, as an appropriate reference soil group. The comparison was conducted on the base of qualitative and semi–quantitative information collected from the literature and experience of the authors – theretical approach. It was conducted in two ways: a) Leptosols vs. Rankers, meaning which Leptosols of WRB for soil resources are Rankers in NSCS, and b) Rankers vs. Leptosols, meaning which Rankers of NSCS are Leptosols in WRB.
The conclusion of our work is that Leptosols RSG can correspond to Rankers in NSCS, but some WRB Leptosols are also Lithosols, Technosols, soils of Subaquatic soil order, Eugleys, Humogleys, Peat Soils, Rendzinas, Kalkomelanosols, Eutric and Dystric Cambisols, whereas Gypsiric Leptosols can not be classified according to NSCS. Observing in different direction, the results show that Ranker Soils could be also part of some other RSG with Leptic principal qualifier, such as Andosols, Phaeozems, Umbrisols, Cambisols, and Regosols. This work represents a small contribution to soil science in Serbia as WRB is comprehensive classification system that enables accommodation of NSCS's for communication at the international level.

AB  - Soil structure pertains to the natural organization of soil particles into various forms as a result of pedogenic processes. On one hand, it is formed in interaction of physical, chemical, mineralogical, and biological factors, whereas on the other hand it affects them. Soil structure can differ in grade of development, size and type of aggregates, and their stability to mechanical pressure and water, which is often soil-horizon or soil-type dependent. This paper aims to analyze the structure of Calcomelanosols of mountain Rtanj, Serbia, as that is the most widespread soil type in this area. Calcomelanosols are soils from the national classification system that often correspond to Rendzic Leptosols in the World Reference Base (WRB) for soil resources. Soil structure is analyzed in terms of soil dry aggregate size distribution (ASD) and soil aggregate stability to water (WAS), and related soil structure indices, as they are essential parameters in understanding the structural state of the soil. Eight soil profiles have been excavated, described and sampled in the field. Soil horizon sequence of all profiles was A – R, with humus-accumulative horizon overlying calcareous bedrock. Six profiles of Calcomelanosols correspond to Rendzic Leptosols of WRB, whereas other two profiles correspond to Leptic Rendzic Phaeozems and Leptic Chernic Rendzic Phaeozems. Basic physical and chemical soil properties were determined. Both ASD and WAS were determined by Savinov's method. The following soil structure indices were calculated: dry mean weight diameter (dMWD), wet mean weight diameter (wMWD), dry geometric mean diameter (dGMD), wet geometric mean diameter (wGMD) and structural stability index (SI). The results indicate favorable structure of the examined Calcomelanosols. The content of agronomically most valuable aggregates (0.25–10 mm) in all soil profiles exceeds 80% (90.5±3.6% on average). Among these aggregates, very fine, fine and medium size aggregates dominate. Dry MWD showed values ranging from 3.0–5.5 mm, whereas wMWD ranges from 1.9– 3.3 mm. The wMWD and dMWD ratio is an indicator of the stability of structural aggregates. A small change in the aggregate size after wet sieving was found, 0.7±0.1 mm on average. In all examined soil profiles SI is higher than 19% (32.9±7.1% on average), which indicates an extremely stable structure, without risk of the structural degradation of soil. Correlation analysis showed a significant positive relationship between the content of agronomically valuable fractions (0.25–10 mm) and the following soil parameters: soil organic matter (SOM), pH, and base saturation (%V). Also, there is a strong positive correlation between SI and pH, and SI with %V. Other calculated structural indices show a strong negative correlation with SOM, pH and %V. All analyzed soil profiles have favorable soil structure and water stable soil aggregates with low risk of soil structure degradation. This is of extreme importance because Calcomelanosols cover the steep and
sloping land which is naturally more prone to soil water erosion and soil degradation.

AB  - Soil moisture and temperature regimes are diagnostic characteristics used for higher categories of the USDA Soil Taxonomy System. The first step of Rendzina soil classification in Serbia according to this international system is to determine the soil temperature and moisture regime classes. As measured soil moisture and temperature data of the investigated Rendzina profiles were missing, the Rendzina soil temperature and moisture regimes were estimated based on climate data (30 years) – monthly and annual air temperature and precipitation, and potential evapotranspiration. Six weather stations were selected: at Novi Sad for the northern, Valjevo for the western, Belgrade for the central, Negotin for the eastern, Sjenica for the southwestern and Niš for the southeastern regions of Serbia. The estimated mean annual soil temperature in the study areas ranged from 8.7 to 14.5°C, and the mean summer and winter soil temperatures differed by 18.6-21.4°C. The Rendzina soils in all the study areas match the criteria for the mesic soil temperature regime. Precipitation becomes greater than potential evapotranspiration and water recharge begins in September in Sjenica and October in the other areas. Potential evapotranspiration exceeds precipitation and utilization starts in March (Novi Sad, Belgrade and Niš) or April (Valjevo, Sjenica and Niš). The amount of moisture stored in the soil during this period, plus precipitation, is believed to be sufficient to support potential evapotranspiration and avoid significant water deficits in western and southwestern Serbia (Valjevo and Sjenica). Utilization is expected to exceed recharge plus precipitation in all other areas, causing soil water deficit to begin in April in Belgrade and May in Novi Sad, Negotin and Niš. Therefore, the soils in the western and southwestern areas match the criteria for the udic soil moisture regime, whereas soils in the other areas (central, east and southeast) correspond to the ustic soil moisture regime. Possibly lower water infiltration and available water capacity, caused by geomorphological and physical properties of Rendzina soils, can increase water deficits further, but precipitation in the summer months is hopefully sufficient to avoid long periods of dry days. Separation of Rendzina soils in Serbia into two soil moisture regimes, udic and ustic, could affect their classification at higher taxonomic levels according to the Soil Taxonomy System.

AB  - The global estimates of soil organic carbon (SOC) stocks using modeling approaches are prone to under and overestimations. The aim of this work is to present the variation of SOC stocks at the foot and toe slopes of Mt. Vukan, East-Central Serbia. Investigated area is located at the contact of Jurassic limestones and dolomites, and fluviatile-colluvial deposits. Soil survey encountered 42 soil profiles and collection of 183 soil disturbed samples, and five undisturbed samples per each horizon. Humus content was determined by Tjurin method. Five different soil mapping units, according to national classification, were discovered at 168 ha of Great Field: Colluvial Kalkomelanosols, Calcaric Chernozems, non-carbonate Chernozems, Eutric Cambisols, and Colluvial Soils. SOC stocks extracted from Soilgrids ranges between 65–72 t ha-1 for 0–30 cm depth (avg. 67.0 t ha-1). Measured data indicate much higher variations, between 50.2 and 110.6 t ha-1, with an average value of 77.8±16.3 t ha-1. Hence, around 15% difference was found between measured and estimated data. Eutric Cambisols have the lowest SOC stocks, 61.3±9.9 t ha-1, lower then estimated value. All other soil types have higher SOC stocks compared with modeled data. Non carbonate Chernozems have an average SOC stocks of 72.6±10.8 t ha-1, whereas Colluvial soil have similar values, 73.6±8.2 t ha-1. The highest SOC stocks was found in Colluvial Kalkomelanosols, 89.6±15.8 t ha-1, followed by Carbonate Chernozems, 84.3±9.3 t ha-1. These values are for 25–33% higher compared with modeled data. Variation of SOC stocks data has normal distribution for all soil types (11.0–18.0%). Our results indicate that global SOC stocks are underestimated in the area of Great Field and that SOC stock can face large variations on small area. These variations might be related to the impact of landscape and land use practices, and are relevant to soil mapping units. Another raising question raised from this study is related to the number of samples that should be collected in SOC campaigns in the conditions of high soil spatial variability.

   total of 1,140 soil profiles. To establish the correlation between organic
   carbon content and soil type, a soil map of Serbia was adapted to the WRB
   classification and divided into 15,437 polygons (map units). The SOC stock
   values were calculated for each reference soil group based on mean values of
   SOC at 0-30 and 0-100 cm and their areas. The largest SOC stocks for the
   soil layers 0-30 cm were found in Cambisol 194.76 x 1012 g and Leptosol
   186.43 x 1012 g and for the soil layers 0-100 cm in Cambisol 274.87 x 1012 g
   and Chernozem 230.43 x 1012 g. Using the Corine Land Cover (CLC) database,
   the major categories of land use were defined. Based on the obtained mean
   values of organic carbon content for the soil layers 0-30 and 0-100 cm and
   the areas indicated by Corine Land Cover categories of land use, the organic
   carbon stocks in agricultural soil, forest soil, semi-natural areas, and
   artificial areas were calculated. The correlation of organic carbon stocks
   and the different land use categories, soil reference group, and soil depth
   was studied for reference groups that occupy the major part of central
   Serbia, such as Cambisol (taking up 37.76% of the territory) and Leptosol
   (22.22% of the territory), and have a sufficient number of sites that were
   required for this type of analysis.

AB  - According to the Serbian official soil classification system, Rendzina is a soil type with an A-AC-C-R profile, developed on parent rock containing more than 20% of calcareous material (except soils with an A-R profile on hard pure limestone or dolomite). Previous investigations have shown that 29 Rendzina soil profiles from Serbia belong to the reference soil groups (RSGs) of Leptosols, Regosols and Phaeozems according to the World Reference Base for Soil Resources (WRB 2015). The present study addresses the correlations among three WRB RSGs in terms of soil texture, mean weight diameter (MWD), total N content, and humus fractional composition using Principal Component Analysis (PCA). The objective is to better understand the mutual relationship between the classification soil units used in Serbia and the international WRB system. The results show that PCA cannot unequivocally distinguish between these three RSGs. Leptosols and Regosols are highly incoherent groups while the group of Phaeozems is highly coherent, leading to the conclusion that the physical and chemical properties of the soil profiles of Phaoeozems are specific. It is obvious that soil depth and color, which are the overriding factors in the differentiation of Rendzina soils into three WRB RSGs, had no significant effect on these properties. The results further show that soil properties such as texture, MWD, humus fractional composition, etc. cannot be used to correlate Rendzina soils from Serbia with WRB. Instead, careful correlation of individual soil profiles is needed based on quantitative soil data analysis as required by WRB.
AB  - Prema zvaničnoj klasifikaciji zemljišta Srbije prema Škoriću i saradnicima, rendzina je tip zemljišta građe profila A-AC-C-R, čiji matični supstrati sadrže više od 20% karbonata (izuzev zemljišta građe profila A-R, obrazovanih na čistim tvrdim krečnjacima i dolomitima). Prethodna istraživanja su pokazala da 29 profila rendzine sa područja Srbije, prema međunarodnoj WRB klasifikaciji zemljišta iz 2015. godine, pripadaju referentnim grupama zemljišta (RSG): leptosola, faozema i regosola. U ovom radu je testiran međusobni odnos izdvojenih WRB RSG prema teksturi, prosečnom masenom prečniku (MWD), sadržaju ukupnog N i frakcionom sastavu humusa, metodom analize glavnih komponenti (PCA), a sve s ciljem boljeg razumevanja međusobnog odnosa klasifikacionih jedinica domaćeg i međunarodnog WRB sistema za klasifikaciju zemljišta. Rezultati su pokazali da PCA ne može na nedvosmislen način da razlikuje ove tri referentne grupe zemljišta. Pri tome su RSG leptosola i regosola veoma nekoherentne, dok je RSG faozema izrazito koherentna što ostavlja prostora za zaključak o specifičnosti fizičkih i hemijskih osobina rendzina koje pripadaju faozemima. Očito je da dubina i boja zemljišta, koje su bile presudne za diferenciranje zemljišta tipa rendzina na tri WRB RSG, nisu imale značajan uticaj na osobine ispitivane u ovom radu. Rezultati su nadalje pokazali da podatke o osobinama zemljišta kao što su tekstura, MWD, frakcioni sastav humusa, itd., nije moguće koristiti za korelaciju zemljišta tipa rendzina u Srbiji sa WRB sistemom klasifikacije, već je neophodna pažljiva klasifikacija svakog pojedinačnog profila zemljišta bazirana isključivo na kvantitativnim podacima koje je WRB sistem predvideo svojim zahtevima.

AB  - This paper presents the variation of soil structure along the foot and toe slopes of Mt. Vukan, East-Central Serbia. The analysis of aggregate size distribution and structure indices were conducted by means of soil units, characteristic soil horizons and elevation differences along the study area. Soils of Great Field located at different elevations were found to have significant variation in ASD and soil structure indices. Topsoil horizon of Eutric Cambisols have higher MWD after dry sieving, but at the same time it has the highest variation in MWD after wet sieving, indicating low water stability, which is opposite to the coefficient of aggregability. We share an opinion that change in MWD better depicts soils structure stability to water. The results of correlation analysis indicated that clay content is correlated more to structure indices compared with SOM content. SOM is significantly correlated with ASD and soil structure indices only in Calcomelansols, whereas the significant correlation of clay content and soil structure is more evident in Eutric Cambisols and Non-calcaric Chernozems, compared with other soil units. Soil structure variation along the lowest chain of Catena might be strong, and that it has to be analyzed from the point of view of soil unit and their corresponding soil horizons.

Differences in temperature and water regimes of Rendzinas on various altitudes are not so prominent to have a significant impact on organic matter composition. Landform has more significant impact, with average higher content of HA on slopes, and FA on flat positions, which could be attributed to reduced wetting of soils on slopes. Exposition had no significant impact on humus composition. Differences in soil moisture among regions are more pronounced than differences in soil temperature. Differences in soil organic matter composition among Rendzinas from various regions are small and do not follow pattern of humidity change. Still, organic matter of Rendzina from most humid western region has the least favourable HA/FA ratio, while at the driest east and southeast regions content of humin is the greatest.

AB  - This study of environmental radioactivity was carried out in the soils of an urban area. Naturally occurring gamma-emitting radionuclides and man-made Cs-137 were found in the soil profiles collected from four parks in the central Belgrade city area and the soil layer was examined every 10 cm and to a depth of 50 cm. Radioisotope activity concentrations (Bq kg(-1)) in the samples of urban soil using the gamma-ray spectrometry method were in the range of 14-46 for U-238, 33-50 for Ra-226, 29-63 for Pb-210, 1.2-3.4 for U-235, 28-50 for Th-232, 424-576 for K-40 and 0.7-35.8 for Cs-137. Some of the basic physicochemical soil properties (pH, organic matter content, calcium-carbonate content, particle size distribution) were determined to investigate the impact on the vertical distribution of radionuclides. The results of this investigation showed that variations of activity concentration ratios of radionuclides that belong to the same (U-238/Ra-226) or different radioactive series (Th-232/Ra-226; U-235/U-238), including Pb-210/Cs-137 ratios could well be explained by the properties of the soil. Alkaline pH reaction, the accumulation of organic matter in the uppermost and of carbonates in the deepest layers of urban soil had an effect on U-238/Ra-226, and Pb-210/Cs-137 activity concentration ratio values, while Th-232/Ra-226 and partially U-235/U-238 ratios were associated with the particle sizes vertical distribution. A study of radionuclides in the samples of leaves of two deciduous tree species common for these parks was also conducted and Pb-210 and K-40 were found concentrated in leaves rather than other investigated radionuclides.

AB  - The surface modification of commercial TiO2 Hombikat (TiO2) using nanoparticles of fullerene C-60 with tetrahydrofuran (THF-nC(60)), as well as fullerenol C-60(OH)(24) nanoparticles (FNP) was investigated in this study. Characterization of THF-nC(60), FNP, TiO2, TiO2/THF-nC(60), and TiO2/FNP was studied by using DES, ELS, TEM, SEM, DRS and BET measurements and their photoactivity has been examined on the mesotrione degradation under simulated sunlight. It was found that FNP in self-assembled nanocomposite TiO2/FNP increased negatively charge, as well as catalytic surface of TiO2. In addition, TiO2/FNP exhibits a shift of band gap energy to lower values compared to TiO2 and TiO2/THF-nC(60). BET surface area has not showed significant differences among catalysts. Furthermore, it was found that the highest photoactivity was obtained for TiO2/FNP system. Besides, influence of different concentrations of electron acceptors (H2O2 and KBrO3), as well as scavengers on the kinetics of mesotrione removal in aqueous solution with/without TiO2 and FNP under simulated sunlight was investigated. Namely, addition of mentioned electron acceptors has resulted in higher mesotrione degradation efficiency compared to O-2 alone. Besides, in the first period substrate degradation probably takes place via hydroxyl radicals and after 60 min of irradiation the reaction mechanism proceeds mainly via holes. The most efficient system for mesotrione degradation and mineralization were TiO2/7 mM KBrO3 and TiO2/7 mM KBrO3/40 mu l FNP, respectively.

AB  - This study examined the impact of climate, altitude and landforms on humic acids (HA) optical properties (E-4/E-6, Delta logK, RF indexes) in Serbian Rendzina soils. HA humification degree of calcareous and decarbonated Rendzinas under natural vegetation (forest and grassland, separately) decreased with altitude increasing. This particular rule was not manifested in arable Rendzinas. HA humification degree in Rendzinas on flat positions (hilltop and footslope) is significantly higher than in Rendzinas on slope sides. Humification degree of HA is the highest in Rendzinas in eastern Serbia (in the vicinity of Negotin), followed by central Serbia (Sumadija) and Srem, southeast and finally, southeast and southwest Serbia. With respect to the climate change foreseen for the end of this century, i.e. increase of precipitation and temperature variance among the regions in Serbia, also an increase in variance of quality of humic acids in Rendzinas on different altitudes and regions can be expected.

AB  - In our recent studies we have designed fullerenol/doxorubicin nanocomposite (FNP/DOX) as the new drug nanocarrier. This research has demonstrated that this novel nanocomposite has had better implications on the liver tissue in vivo (Wistar rats treated intraperitoneally), than treatment based only on DOX. FNP/DOX has been characterised by DLS, TEM and AFM measurements which have shown that DOX loaded onto FNP did not influence fullerenol nanoparticle's size. FNP/DOX affected oxidative status in blood causing a significant decrease of catalase and SOD activity in comparison to DOX, implicating the reduction in oxidative stress. qRT-PCR results on the mRNA level of antioxidative enzymes (catalase and MnSOD) revealed that the effect of oxidative stress is significantly reduced by the treatment with FNP/DOX (p lt .05). The ultrastructural analysis of the liver tissue has revealed that FNP/DOX nanocomposite generated considerably less damage in the liver tissue, than DOX applied at the same dose. Hence, our results have indicated that FNP, within FNP/DOX nanocomposite, exhibits protective effects to the liver tissue of the healthy rats.

AB  - This study aims at analysing physical, chemical and microbiological properties, and content of macro- and microelements in the water from the Požarevac city public water supply system. Analysis shows an increased content of Ca in drinking water, as a result of the position of Požarevac on the sediments of river terrace of accumulative character of t1 type, predominantly consisting of quartzite. The water from the public water supply is alkaline ('calcic', 'bicarbonate water') and very hard, due to the increased Ca content. Beside Ca, potassium and aluminium exceed the maximum contaminant level, while Pb and Cd are at the very limit. Calculated data show that there are no short-term health risks regarding elements exceeding allowed concentrations found in the public water supply system. Data analysis regarding long-term health risks shows that Cd present in drinking water poses the only relevant threat to human health. Cancer risk is present in 202 out of 1000 inhabitants using this water.

AB  - The paper presents results of investigation of the influence of mechanical activation of shungite, a Russian natural mineral rich in silica and carbon, on its sintering behavior. The mechanical activation of the starting powder was performed in a high-energy ball mill in time intervals from 0 to 480 minutes. The phase composition of the starting mixtures and sintered samples was analyzed by the X-ray diffraction method. The scanning electron microscopy was performed in order to determine changes in the microstructure. Sintering was performed at various temperatures for 2 h, in an Ar and vacuum atmosphere. Dielectric properties of the sintered samples were measured in the frequency range from 1 to 500 MHz. The obtained results indicate that sintered shungite powder is a good candidate for applications as an absorber of electromagnetic waves in microwave engineering.

AB  - Land degradation neutrality (LDN) is defined as a state whereby the amount and quality of land
resources necessary to support ecosystem functions and services and enhance food security remain stable or increase within specified temporal and spatial scales. This concept is a part of sustainable development goal 15 of the UN Agenda for Sustainable Development. Target 15.3 aims to combat desertification, restore degraded land and soil, including land affected by desertification, drought and floods, and strive to achieve a land degradation-neutral world by 2030. The achievement of this target is measured through indicator called “Proportion of land that is degraded over total land area”. United Nations Convention to Combat Desertification (UNCCD) endorsed SDG target 15.3 and the concept of land degradation neutrality as a strong vehicle for the implementation of the Convention. Countries are invited to formulate voluntary targets to achieve LDN. UNCCD provide guidance for formulating national voluntary targets and facilitate utilization of the UNCCD indicator framework. Republic of Serbia has ratified Convention in 2007 and actively works on LDN target setting process. This paper aims to present: (a) the basic principles of LDN concept, (b) global datasets provided by UNCCD, (c) SWOT analysis for the country, and (d) to discuss possible national datasets and further activities related to LDN.
Indicator “Proportion of land that is degraded over total land area” is measured by means of three subindicators: land cover, land productivity and soil organic carbon. This indicator framework could be broaden with national indicators by decision of the country. Country has been provided by global data on land cover from European Space Agency (ESA). Land productivity dynamics (LPD) dataset was prepared by Joint Research Centre of the European Commission, while soil organic carbon (SOC) dataset was provided by ISRIC. Watershed boundaries are provided from FAO GAUL network. Net area change as a result of comparison between two periods for land covers change and SOC, while LPD is obtained as a trend for the 15 years period. ESA land cover data are given for the two epochs, around 2000 and 2010. These data indicate the loss of 3,800 ha of forests and their conversion to croplands or shrubs. National datasets on land cover exist but their utilization is constrained with the necessity to have dataset for two period of time and to have regular acquisition of future data which are necessary for further analysis and monitoring.
Land productivity dynamics data indicated that 5% of the Serbian territory has negative trends in land productivity for the period 1998-2013. There are no national data on LPD obtained according to LDN concept. Soil organic carbon for the country indicates average content of 82.2 t/ha. National data on SOC stocks exist in the databases of relevant institutions but the problems in their utilization are related to the fact that they are sometimes very old, rarely geo-referenced, and obtained by various analytical and terrain procedures. Hence, global data on SOC stocks do not present real country situation, while national SOC stocks data should be systematized to be confident. Indicator analysis at watershed level has recognized the watersheds of Great Morava, Tisa, Sava 3 and South Morava and Nisava rivers, as four watersheds which present 50% of degraded areas according to the proposed methodology. These watersheds should be prone to detailed analysis of around 20 potential hotspots are found in the country. LDN baseline is not yet decided on a country level. Global land cover and land productivity dynamics data will be used until we obtain national data for these indicators. SOC national data should be systematized and used instead of global data. Further activities in LDN target setting process are related to the establishment of LDN baseline, analysis of land degradation trends and drivers, and suggestion of possible national voluntary targets and associated measures at the country, local and/or watershed level. The inclusion of national indicators should be further discussed. LDN concept should be strongly lead by the Government of Republic of Serbia. Hence, Serbian UNCCD NAP document should be finalized, adopted by the Government and LDN embedded into the NAP.

AB  - According to soil classification system used in Serbia (Škorić, Ćirić and Filipovski, 1985) Rendzina is a soil type within the order of automorphic soils and the class of humus-accumulative soils with an Amo-AmoC-C-R profile, which is developed on parent rock containing more than 20% of calcareous material. Rendzinas are divided onto subtypes - according to the parent material: (i) marl, marly limestone and soft limestone, (ii) loess and loess like sediments, (iii) dolomite sand, (iv) moraine; on varieties - according to stadium of evolution: (i) calcareous, (ii) decarbonated, (iii) brunified, (iv) colluvial, and forms - according to texture and coarse fragments content. Throughout the world, the term Rendzina (and Pararendzina) is used to denote soils formed on different calcareous parent material and it generally corresponds with Rendzic Leptosol of the WRB soil classification system. Rendzinas on marl, marly limestone and soft limestone is the most widespread subtype in Serbia, and the aim of this study was to precisely classify it according to the WRB 2015 system. Total of 29 Rendzina soil profiles from different parts of Serbia were studied. Field and laboratory investigations (soil depth, colour, coarse fragments, texture, structure, pH, soil organic carbon, base saturation) were determined using methods recommended by the WRB system (except for base saturation, where BaCl2, pH 8.1, was used instead of NH4OAc, pH 7).
According to soil classification system used in Serbia, from total of 21 soil profiles on soft limestone, 16 were calcareous variety (form: 8 loamy, low or medium skeletal and 1 clay, medium skeletal); 13 decarbonated variety (loamy, low skeletal); and 2 colluvial variety (loamy, low skeletal); and 8 profiles on marl of which 7 were calcareous variety (loamy, low or medium skeletal), and 1 profile was decarbonated variety (loamy, low skeletal). According to WRB 2015 system, investigated Rendzinas were classificated to RSG of Leptosols (12 profiles), Regosols (10 profiles) and Phaeozems (7 profiles). Leptosols include Rendzinas with A-R soil profile, where continuous rock (10 profiles on soft limestone and 2 profiles on marl) starting ≤15-25 cm from the soil surface. For calcareous Rendzina variety, combinations of the principal qualifiers were: Rendzic, Rendzic Calcaric, and Skeletic Calcaric. The decarbonated variety matched the
diagnostic criteria for the Eutric principal qualifier. The supplementary qualifiers for Leptosols were
Loamic or Clayic, Aric and Humic. Renzinas deeper than 25 cm, usually with A-AC-R soil profile, having a mollic diagnostic horizon were classified to RSG of Phaeozems. For calcareous Rendzinas variety, combinations of the principal qualifiers were: Rendzic Calcaric or Rendzic Skeletic Calcaric. The decarbonated Rendzinas variety only matched criteria for the Leptic principal qualifier. Loamic and Aric supplementary qualifiers were added to Phaeozems.
RSG of Regosols includes Rendzinas thicker than 25 cm, usually with A-AC-R soil profile, when
surface horizon does not match diagnostic criteria of a mollic horizon (in slightly crushed samples a
Munsell colour value of ≥3 moist, and ≤ 5 dry, and a chroma of ≥4 moist). Surface horizons were more than 20 cm deep (except for 2 profiles) and had over 0.6% (1.1-4.6%) soil organic carbon. For calcareous Rendzinas variety combinations of the principal qualifiers were: Leptic Calcaric or Leptic Skeletic Calcaric. For Colluvial Rendzinas variety (all calcareous) combination of the principal qualifiers was: Leptic Colluvic Calcaric. Loamic and Aric and/or Humic supplementary qualifiers were used for Regosols. Soil depth caused the first differentiation between Leptosols and Phaeozems, and soil (moist) colour caused the second differentiation between Phaeozems and Regosols. Somewhat brighter soil colour of Rendzina/Regosols is a result of low soil organic matter content and/or high content of calcaric material in the fine earth.

AB  - This study describes and classifies the soils of the foot and toe slopes of the Vukan Mountain, Central Serbia, the contact point of two distinct geomorphological units, with a focus on their spatial distribution and their main soil-forming processes. The Vukan Mountain is formed of Jurassic limestones and dolomites, whereas the foot and toe slopes are of fluviatile-colluvial origin. A total of 42 soil profiles were examined. Soil profile locations were determined with respect to elevation differences, accounting for a set of six profiles for every 5-m elevation increase between 175 and 210 m a.s.l. The area is characterized by the dominance of chernic and mollic topsoil horizons and the major part of the area is covered with Phaeozems. Five Reference Soil Groups were found in a very small area. Eleven soil profiles are Chemic Phaeozems, five are Cambic Phaeozems, and twelve are Rendzic Phaeozems. The central part of the study area is characterized by the accumulation of secondary carbonates and Chernozems were identified. The northern part of the study area is covered with Fluvisols, Calcisols, and Leptic Rendzic Phaeozems, whereas Chernic and Cambic Phaeozems and Eutric Cambisols cover the western part of the study area. The differences in the CaCO3 content in the gravels, the differences in the gravel content, and the different lateral and vertical distribution of CaCO3 are strong evidence of surface processes that occurred in the past. The presence of different geological layers and buried horizons suggests fluviatile processes. The spatial distribution of soils is related mainly to parent material occurrence, and colluvial and alluvial processes that occurred in the past. The soil map created in GIS has Reference Soil Group as central unit following Rule 1 for map legend creation, except in the case of Phaeozems, which are present as Phaeozems (Leptic) and Phaeozems (other) following Rule 5. This soil survey with approximately one soil profile per 4 ha has indicated considerable soil heterogeneity in the study area. Detailed surveys are therefore recommended for areas with pronounced heterogeneity of soil-forming factors.

AB  - The content and behaviour of metals in agricultural soils are very important for food safety. The results presented in this paper are part of a great research that includes monitoring of the parameters in the soil and plant at the site of the largest power plant in Serbia. Part of the study presented in this paper investigates soil contamination with Cd and Zn and their translocation to edible parts of spelt (Triticum spelta L.) with calculation of bio-accumulation factor (BAF). Spelt is well adapted to marginal lands and present healthy attractive crop which better absorb nutrients from soil comparing to common wheat. Oppositely to common wheat its grains have high protein content but a low Cd content. The DTPA-extractable BAF values of Zn for almost every crop were higher than those for Cd, indicating that Zn is more easily translocated into the plant from soil than Cd. BAF indicates possibility of toxic metal implementation into the food chain. Comparing to previous research, studied spelt showed a high translocation of Zn and Cd from the soil to the edible part of plant, even though the concentration of Zn and Cd in soil were below the threshold limit for agricultural soils.

AB  - n The present paper focuses on the determination of radiological characteristics of cultivated chernozem soil and crops from long-term field experiments, taking into account the importance of distribution and transfer of radionuclides in the soil-plant system, especially in agricultural cropland. The investigation was performed on the experimental fields where maize, winter wheat, and rapeseed were cultivated. Analysis of radioactivity included determination of the gross alpha and beta activity as a screening method, as well as the activities of the following radiouclides: natural (Pb-210, U-235, U-238, Ra-226, Th-232, K-40, Be-7) and artificial (Sr-90 and Cs-137). The activities of natural and artificial (Cs-137) radionuclides were determined by gamma spectrometry, while the artificial radionuclide Sr-90 was determined by a radiochemical analytical method. Based on the obtained results for the specific activity of K-40, Cs-137, and Sr-90, accumulation factors for these radionuclides were calculated in order to estimate transfer of radionuclides from soil to crops. The results of performed analyses showed that there is no increase of radioactivity that could endanger the food production through the grown crops.

AB  - An experiment was undertaken to evaluate the effect of liquid manure amendment on heavy metal accumulation in wheat and barley. For this purpose, both kinds of seedlings were grown simultaneously in a Petri dish, while wheat seedlings were also grown in pots containing unpolluted agricultural soil. All of the seedlings were irrigated with one of the three prepared solutions: artificial rainwater solution, heavy metal solution and liquid manure solution containing NH4NO3, H3PO4 and KOH along with equal amounts of heavy metals as in the second solution. Twenty days later, 1g of plant tissue was digested with the mixture of HNO3 and H2O2 for ICP-OES/HG-ICP-OES analysis. The results showed that the uptake of arsenic and mercury was highest for both plants grown in a Petri dish. Furthermore, the wheat grown in a Petri dish also had a high content of nickel, cadmium and copper, while the pot-grown wheat contained high amounts of iron and manganese, probably due to the adsorption of nickel, cadmium, copper and mercury on soil phases. The lower uptake of all heavy metals was observed after the amendment of liquid manure, with the exception of manganese in wheat and mercury in all plants.
