AB  - Scarce water resources severely limit maize (Zea mays L.) cultivation in the temperate regions
of northern Serbia. A two-year field experiment was conducted to investigate the effects of
irrigation and planting density on yield and water use efficiency in temperate climate under
sprinkler irrigation. The experiment included five irrigation treatments (full irrigated treatment – FIT; 80% FIT, 60% FIT, 40% FIT, and rainfed) and three planting densities (PD1: 54,900 plants ha–1
; PD2: 64,900 plants ha–1; PD3: 75,200 plants ha–1). There was increase in yield with the irrigation (1.05–80.00%) as compared to the rainfed crop. Results showed that decreasing irrigation rates resulted in a decrease in yield, crop water use efficiency (WUE), and irrigation water use efficiency (IWUE). Planting density had significant effects on yield, WUE, and IWUE which differed in both years. Increasing planting density gradually increased yield, WUE, and IWUE. For the pooled data, irrigation rate, planting density and their interaction was significant (P < 0.05). The highest two-year average yield, WUE, and IWUE were found for FIT-PD3 (14,612 kg ha–1), rainfed-PD2 (2.764 kg m–3), and 60% FITPD3 (2.356 kg m–3), respectively. The results revealed that irrigation is necessary for maize cultivation because rainfall is insufficient to meet the crop water needs. In addition, if water becomes a limiting factor, 80% FIT-PD3 with average yield loss of 15% would be the best agronomic practices for growing maize with a sprinkler irrigation system in a temperate climate of Serbia.

AB  - Land use in agriculture can alter the physical, chemical and biological properties of soils, but little is known how it affects the hydraulic properties of the fine-textured soils of lowland agroecosystems in continental climates. This research assesses the impact of long-term (>100 years) continuous use of natural meadows and arable land, after conversion of native mixed deciduous forests, on hydraulic properties such as water retention, pore-size distribution, saturated hydraulic conductivity, and bulk density. The research was conducted on Fluvic Phaeozems in the valley of the Kolubara River, western Serbia. Disturbed and undisturbed soil samples from three different land use systems (forest, meadow, and arable land) and three different locations were collected at 0–15, 15–30, and 30–45 cm soil depth. Significant effects of different land uses were observed for bulk density, total porosity, macroporosity, mesoporosity, microporosity, air-filled porosity, field water capacity, plant available water capacity and saturated hydraulic conductivity at 0–15 cm soil depth, but a much smaller effect was observed at 15–30 cm. The water content estimated by the van Genuchten model was similar to the measured water content (R2 = 0.932–0.972). At 30–45 cm soil depth, land use only significantly affected a few of the examined variables. Dexter's soil physical quality index (S-index) also detected degradation of soil physical quality after conversion from forest to agroecosystems. In summary, the conversion of native forests into agricultural land tends to cause considerable change in the hydraulic properties and soil physical quality of fine-textured soils in lowland continental agroecosystems, which could have an adverse effect on crop yield and the environment. © 2022

AB  - Natural grasslands and pastures occupy 5.96% of the country territory. According to European Space Agency, changes in land cover from 2000–2015 indicate decrease in total grassland area of 1765 km2 (30.03%), emphasizing dominant conversion of grasslands to forests. Ongoing depopulation trend, rural to urban migrations, and decrease in livestock population are some of main factors impacting grasslands. This trend favors further naturalization of pastures striving to increase the areas under natural grasslands. Such conversion will contribute to overall change in biodiversity richness, especially in areas with saline soils and high mountain regions with increased level of endemic species. Grasslands play important role in overall sustainability, but their importance it is not properly addressed. Environmental experts should recognize drivers of grasslands degradation and propose appropriate conservation and restoration measures. The priority should be avoidance of grassland degradation that requires good assessment of their current conditions and monitoring of plant, soil, climate conditions and land use activities. Further measures are deduced to sustainable land management practices and smooth human interventions, whereas the aftermost adopted measures should be related to restoration. Grasslands should have more emphasized role in our society and LDN principles should be applied for their preservation.

AB  - Over the last two decades, Serbian agriculture has suffered increased losses and damages due to the more frequent occurrence of the extreme weather events caused by the climate change. The most significant losses are recorded in years with droughts and high summer temperature (such as 2012 and 2017). Significant losses in orchards are caused by the frost in late winter or early spring, when the flowering occurs early, due to a prolonged period of unusually high temperatures. On the other hand, damages caused by low winter temperatures are decreasing.

In order to assess the risk levels brought by the climate change and extreme weather events to the agricultural plant production in different regions of the country, analyzed are frequency of the occurrence of the weather events that may have significant negative effect to the yields of the most important crops (corn, maize, sunflower, soybeans) and fruits (plum, peach, raspberry, apple, wine grape), as well as pastures and meadows. Vulnerability is assessed through the analysis of agricultural production structure in the administrative districts of Serbia.

Weather events with potentially negative effect to yields and most vulnerable phenophases are defined for each crop or fruit considered in the analysis. For each plant and each potentially dangerous weather event one or more bioclimatic indices were adopted and calculated for the past, present and future. For the present (2000-2019), daily data on temperature and precipitation were used from the eOBS gridded observations dataset. Results of 8 regional climate models from the EURO-CORDEX initiative were combined into an ensemble. The ensemble was constructed upon the evaluation of their ability to simulate past climate characteristics over the country. The chosen simulations are done under the RCP8.5 IPCC greenhouse gasses emission scenario, for the periods 1986-2005, 2021-2040, 2041-2060 and 2081-2100.

Results showed that projected frequencies of the events such are water deficit and/or droughts and high temperatures in the critical phenophases of the considered plants, and late spring frost, are increasing in the future. The median value of the frequency of those weather events projected for the next 20 years is mostly already reached. Therefore, more weight is given to the 75th percentile of the ensemble projections for the increasing risks and the 25th percentile for the decreasing risks, as upper and lower limits of the most probable range of the future climate changes.

This assessment is used for drafting the National Climate Change Adaptation Plan in order to propose and prioritize adaptation measures for the agricultural sector in the Republic of Serbia, on the national and administrative districts level.

abstract = "Over the last two decades, Serbian agriculture has suffered increased losses and damages due to the more frequent occurrence of the extreme weather events caused by the climate change. The most significant losses are recorded in years with droughts and high summer temperature (such as 2012 and 2017). Significant losses in orchards are caused by the frost in late winter or early spring, when the flowering occurs early, due to a prolonged period of unusually high temperatures. On the other hand, damages caused by low winter temperatures are decreasing.

In order to assess the risk levels brought by the climate change and extreme weather events to the agricultural plant production in different regions of the country, analyzed are frequency of the occurrence of the weather events that may have significant negative effect to the yields of the most important crops (corn, maize, sunflower, soybeans) and fruits (plum, peach, raspberry, apple, wine grape), as well as pastures and meadows. Vulnerability is assessed through the analysis of agricultural production structure in the administrative districts of Serbia.

Weather events with potentially negative effect to yields and most vulnerable phenophases are defined for each crop or fruit considered in the analysis. For each plant and each potentially dangerous weather event one or more bioclimatic indices were adopted and calculated for the past, present and future. For the present (2000-2019), daily data on temperature and precipitation were used from the eOBS gridded observations dataset. Results of 8 regional climate models from the EURO-CORDEX initiative were combined into an ensemble. The ensemble was constructed upon the evaluation of their ability to simulate past climate characteristics over the country. The chosen simulations are done under the RCP8.5 IPCC greenhouse gasses emission scenario, for the periods 1986-2005, 2021-2040, 2041-2060 and 2081-2100.

AB  - Universal Soil Loss Equation (USLE) is the most applied model for soil erosion assessment. It
takes into consideration five soil erosion factors among which soil erodibilty factor (K) is a
measure of inheritant reistance of soils to erosion. In the formulation of USLE model, K–factor
was determined experimentally, and then the authors created USLE nomograph to facilitate the
work, and in the next step, created the equation for faster K–factor determination. This paper
aims to compare K–factor obtained by USLE nomograph and USLE equation. A total number of
108 soil samples have been collected in Western Serbia. For the determination of K–values,
particle size distribution and soil organic matter were analyzed in the laboratory, whereas soil
permeability and soil structure were assessed according to the USLE document procedure. The
results have been compared using basic statistics. The average K–values obtained by nomograph
and equation differ for almost 15%. There is statistically significant correlation between the two
methods, but coefficient of determination amounts to 0.5802, which indicates pretty high
deviation. Root Mean Square Error (RMSE) amounts to 0.008, which is quite high, whereas
index of agreement amounts to 0.93, representing good agreement. These results are ambiguous.
We think that 15% of absolute error is a threshold value between single samples, which occur in
only 56% of the cases. Therefore, the obtained results indicate the gaps in the determination of
K–factor and could contribute to further improvment of soil erodibilty determination and
consequently, soil erosion assessment.

AB  - Universal Soil Loss Equation (USLE) is the most applied model for soil erosion assessment. It takes into consideration five soil erosion factors: rainfall erosivity, topographic factor, vegetation cover, applied conservation practices, and soil erodibility. Soil erodibilty factor (K-factor) is a measure of inheritant reistance of soils to erosion. In the formulation of USLE model, K-factor was determined experimentally. Experimental determinations are costly and time- consuming, so the authors have encouraged scientists to utilise USLE nomograph or derived equations. This paper aims to compare USLE nomograph and soil erodibility equation which was derived from nomograph by the same authors. A total number of 108 soil samples have been collected on agricultural land of Western Serbia. For the determination of K-values, particle size distribution and soil organic matter content were determined in the laboratory, whereas soil permeability and soil structure were assessed according to the nomograph. The results have been compared using basic statistics. The average K-values obtained by nomograph and derived equation are 0.034±0.010 and 0.029±0.012, which is 14.7% difference. Coefficient of determination (R2) amounts to 0.5802, which indicates deviation of 23.9%, although there is statistically significant correlation between two methods. Root Mean Square Error (RMSE) is 0.008, which is 23–27% difference. The RMSE is not low, whereas index of agreement amounts to 0.93, which represent good agreement, and also there is significant correlation. These results are ambiguous. We think that 15% of absolute error is a threshold value for good correlation, which occur on only 56% of samples. K-factor is an important part of various soil erosion models and it is of high importance to determine it in the best manner. Therefore, the obtained results indicate the gaps in the determination of K-factor and could contribute to further improvment of soil erodibilty determination and consequently, soil erosion assessment.

AB  - INTRODUCTION and OBJECTIVES: Remote sensing is the process of detecting and monitoring the physical characteristics of an area by measuring its reflected and emitted radiation at a distance, and in a narrower sense includes the analysis and interpretation of various images of parts of the Earth's surface. The application of satellite images with modern technology and software is possible in all phases of research of various natural phenomena, and their analysis are carried out by computer-aided and visual procedures. The aim of this research is to present the basic aspects of remote sensing and modern technologies in assessing the water supply of natural grasslands, as well as the presentation of possibility for faster data collection while reducing costs, and easier understanding of the whole research area.
MATERIAL and METHOD: The trial was set on March 22nd of 2022 on a natural grassland in the village of Mitrovo polje on the mountain Goč (43° 30′ 22′ N latitude, 20° 52′ 26′ E longitude, 700 m a.s.l.) in the Aleksandrovac municipality. Disturbed and undisturbed soil samples were collected to determine soil texture, soil water retention characteristics and soil chemical properties. Continuous measurement of soil moisture was performed with TDR probes in three replicates and sensors for monitoring soil temperature were installed. The satellite images (SENTINEL 2) with a resolution 10 m, in a time interval of about a week, created in relatively clear weather (cloudiness <30%), starting from March 22 to May 21st were used,
while soil moisture data were collected on a daily basis. Data on precipitation and air temperature for the observed period were taken from the Agrosens portal. The supply of natural grassland with water and assessment of soil moisture are determined by the index of normalized difference vegetation index (NDVI), as the most applicable vegetation index. NDVI is defined as the ratio of differences between individual values of reflective wavelengths of near red and red radiation spectrum and their sum. Furthermore, for the
analysis are also used MSAVI2 index, which is mainly used to analyse plant growth, estimate grass yield, monitor drought and soil erosion, and the optimized soil-adapted vegetation index (OSAVI), which is more sensitive to vegetation. The analysis of remotely sensed images of the investigated area and statistical analysis were conducted using QGIS tools.
RESULTS and CONCLUSIONS: The results of the research show that from the beginning of grassland growth, the soil moisture ranged from 39% to 57%, which indicates that the lawn was well supplied with water. Water consumption was low at initial stage of grass growth. Soil water content at that period was high due to subsurface inflow coming from the higher parts of the terrain. The values of the NDVI index varied from 0.16 to 0.47, while the values for the MSAVI2 and OSAVI index ranged from 0.59-0.73 and
0.24-0.63, respectively. Lower index values at the beginning of the observed period (<0.16, <0.32, <0.30 for NDVI, MSAVI2 OSAVI, respectively) indicate a lack of green biomass. As the growth of natural grass increased, so do the values of all indices. Nevertheless, the obtained results show the changes of vegetation indices with the change of soil moisture, i.e. the values of the index increase due to the increase of soil
moisture after precipitation and vice versa, which leads us to the conclusion that the application of remote sensing indices can be successfull for the estimate of different vegetation conditions, detection ofsoil moisture and biomass assessment.

AB  - УВОД и ЦИЉЕВИ: Даљинска детекција је поступак откривања и праћења физичких карактеристика подручја мерењем његовог одбијеног и емитованог зрачења на даљину, а у ужем
смислу обухвата анализу и интерпретацију различитих снимака делова Земљине површине. Примена сателитских снимака уз савремену технологију и програмску подршку могућа је у свим
фазама истраживања различитих природних појава, а њихова анализа се спроводи рачунарски подржаним и визуелним поступцима. Циљ овог истраживања је да се представе основни аспекти
примене даљинске детекције и савремених технологија при процени снабдевености природних травњака водом, као и могућност бржег прикупљања података уз смањење трошкова и лакше сагледавање целине истраживаног подручја.
МАТЕРИЈАЛ и МЕТОД: Оглед је постављен 22.03.2022. на природном травњаку у селу Митрово поље на планини Гоч (43° 30ʹ 22ʺ с.г.ш. и 20° 52ʹ 26ʺ и.г.д., 700 m н.в.), општина Александровац. На терену су узети узорци земљишта у поремећеном и непоремећеном стању како би се одредио механички састав, водне константе као и поједине хемијске особине земљишта. Континуално мерење влажности земљишта обављено je TDR сондама у три понављања и постављени су сензори
за праћење температуре земљишта. У раду су коришћени сателитски снимци (SENTINEL 2), резолуције 10m, у временском интервалу од око недељу дана, направљени при релативно ведром времену (облачност <30 %), почевши од 22. марта до 21. маја, док је влажност земљишта одређивана на дневном нивоу у истом периоду. Са портала Agrosens преузети су подаци о падавинама и температури ваздуха за посматрани период. Снабдевеност природних травњака водом и процена стања влажности земљишта одређена је индексима нормализоване разлике индекса вегетације (NDVI), као најчешће коришћеним индексом стања вегетације и дефинише се као однос разлика између појединих вредности рефлектујућих таласних дужина – одбијања блиско црвеног и црвеног спектра зрачења и њихове суме, затим индекс MSAVI2, који се углавном користи у анализи раста
биљака, при процени приноса травњака, праћењу суше и ерозије тла, док је оптимизовани вегетациони индекс прилагођен тлу (OSAVI) осетљивији на вегетацију. Анализа снимака за креирани полигон истраживаног подручја и статистичка анализа урађена је помоћу QGIS алата. 
РЕЗУЛТАТИ и ЗАКЉУЧЦИ: Резултати истраживања показују да се од почетка вегетативног раста влажност земљишта кретала од 39% до 57% што указује да је травњак био добро снабдевен водом. Потрошња воде била је мања од прилива воде доспеле услед потповршинског дотицаја са виших делова терена.

abstract = "УВОД и ЦИЉЕВИ: Даљинска детекција је поступак откривања и праћења физичких карактеристика подручја мерењем његовог одбијеног и емитованог зрачења на даљину, а у ужем
смислу обухвата анализу и интерпретацију различитих снимака делова Земљине површине. Примена сателитских снимака уз савремену технологију и програмску подршку могућа је у свим
фазама истраживања различитих природних појава, а њихова анализа се спроводи рачунарски подржаним и визуелним поступцима. Циљ овог истраживања је да се представе основни аспекти
примене даљинске детекције и савремених технологија при процени снабдевености природних травњака водом, као и могућност бржег прикупљања података уз смањење трошкова и лакше сагледавање целине истраживаног подручја.
МАТЕРИЈАЛ и МЕТОД: Оглед је постављен 22.03.2022. на природном травњаку у селу Митрово поље на планини Гоч (43° 30ʹ 22ʺ с.г.ш. и 20° 52ʹ 26ʺ и.г.д., 700 m н.в.), општина Александровац. На терену су узети узорци земљишта у поремећеном и непоремећеном стању како би се одредио механички састав, водне константе као и поједине хемијске особине земљишта. Континуално мерење влажности земљишта обављено je TDR сондама у три понављања и постављени су сензори
за праћење температуре земљишта. У раду су коришћени сателитски снимци (SENTINEL 2), резолуције 10m, у временском интервалу од око недељу дана, направљени при релативно ведром времену (облачност <30 %), почевши од 22. марта до 21. маја, док је влажност земљишта одређивана на дневном нивоу у истом периоду. Са портала Agrosens преузети су подаци о падавинама и температури ваздуха за посматрани период. Снабдевеност природних травњака водом и процена стања влажности земљишта одређена је индексима нормализоване разлике индекса вегетације (NDVI), као најчешће коришћеним индексом стања вегетације и дефинише се као однос разлика између појединих вредности рефлектујућих таласних дужина – одбијања блиско црвеног и црвеног спектра зрачења и њихове суме, затим индекс MSAVI2, који се углавном користи у анализи раста
биљака, при процени приноса травњака, праћењу суше и ерозије тла, док је оптимизовани вегетациони индекс прилагођен тлу (OSAVI) осетљивији на вегетацију. Анализа снимака за креирани полигон истраживаног подручја и статистичка анализа урађена је помоћу QGIS алата. 
РЕЗУЛТАТИ и ЗАКЉУЧЦИ: Резултати истраживања показују да се од почетка вегетативног раста влажност земљишта кретала од 39% до 57% што указује да је травњак био добро снабдевен водом. Потрошња воде била је мања од прилива воде доспеле услед потповршинског дотицаја са виших делова терена. Вредности индекса NDVI варирале су од 0,16 до 0,47 док су се вредности за MSAVI2 и OSAVI индекс кретале од 0,59-0,73 односно 0,24-0,63. Ниже вредности индекса на почетку посматраног периода (<0,16, <0,32, <0,30 за NDVI, MSAVI2 OSAVI, редом) указују на недостатак зелене биомасе. Кретањем раста природног травњака, расту и вредности свих индекса. Потом,

AB  - Climate change in Europe will lead to new precipitation patterns over the coming years and the annual temperature will increase significantly. These changes in climate variables and the resulting effects on agricultural productivity must be differentiated regionally. Plant production depends on sufficient rainfall in summer and, in some regions, on the amount of rainfall in winter. In Central Europe, the amount of precipitation in summer will
decrease in the coming decades due to climate change, while in some regions, the amount of winter precipitation will increase significantly. Agricultural production is likely to suffer severely as a result of rising summer temperatures and low water retention capacities in the soil. The effects of reduced summer precipitation and increased air temperatures are
partially offset by the expected increased CO2 concentration. Therefore, the effects that changed climatic conditions have on crop production are sometimes less drastic in terms of crop yields. The greatest impact of climate change on land use is expected from increasing evapotranspiration and lower amounts of precipitation in the production of leachate. In addition to the expected mean changes, the occurrence of extreme weather conditions is
key. Periods of drought in the growing season and heavy flooding as a result of extreme rainfall are to be expected. However, these events are very difficult or even impossible to predict. In addition to the effects that climate change will have on regional crop production, global changes will have a strong impact on world markets for agricultural products. Another consequence of climate change and population growth is a higher demand for agricultural products on world markets. This will lead to dramatic local land use changes and an intensification of agriculture that will transform existing crop production systems. The intensification caused by rising land and lease prices will
primarily affect the maximization of the use of fertilizers and pesticides.

AB  - Knowledge of hydro-physical properties is an essential prerequisite for assessing the suitability and quality of growing media. The method used for sample preparation is important for the measurement results. Three different sample preparation methods were compared. The methods differed in terms of the way the 250°cm3 steel cylinder was filled and the height of preloading. Measurements on loosely filled cylinders were included. The comparison was carried out on 15 growing media using the HYPROP device. HYPROP enables a complex analysis of the hydro-physical properties with high accuracy and reproducibility. The water retention curve, the unsaturated hydraulic conductivity function, the dry bulk density, the shrinkage and the rewetting properties can be measured simultaneously. The air capacity and the amount of plant-available water in pots depend on the height of the pot. In the field, it is related to the field capacity. The quality assessment was carried out both for flowerpots of different height and for field conditions with free drainage. Loosely filled samples consolidated hydraulically shortly after the start of the measurement. These geometric changes can be taken into account with the HYPROP. The sample preparation method – preloading or loose filling – yielded significantly different results for the pore volume, dry bulk density, plant available water and air capacity. The total pore volume of the loosely filled cylinders varied between 86.8 and 95.2°% by vol. (preloaded 81.3 and 87.7°% by vol.). The most critical factor was the air capacity. Loosely filled substrate samples achieved the highest air capacities, but also did not reach the critical value of 10°% by volume in shallow flowerpots, e.g. in 10 cm pots with 5.8°% by volume. The sample preparation method, measurement and quality assessment of the hydro-physical properties of growing media
should be adapted to the conditions of use – whether they are used in a field with free drainage or in pots or containers in greenhouses.

AB  - The eutrophication of groundwater through widespread diammonium phosphate (DAP) fertilization and excessive farm fertilizer is one of the major problems in European agriculture. Organomineral microgranular fertilizers that have a reduced phosphorus (P) content, alone or in combination with
biostimulants, offer promising alternatives to DAP fertilization. We conducted a field experiment with maize (Zea mays) on a marshland soil site in order to compare the yield increase and the phosphorus balance of DAP and microgranular fertilizer variants. P content of the soil on the study site is 3.9 g P per 100 g soil. Treatments involved a combination of two fertilizers, namely DAP or a P-reduced microgranular slow-release organomineral fertilizer (Startec) and the biostimulants mycorrhiza, humic substances and soil bacteria, applied individually or along with two of the above biostimulants.
Fertilizer variants were also tested individually without additional biostimulants. One in four plots was used as a control, treated only with biogas slurry, to identify site-specific spatial variability and to implement correction factors to process raw data using standardized methods. Startec performed as well as DAP in terms of both the yield and corn cob ratio, while the P excess was lower in plots treated with Startec (av. = 4.5 kg P2O5 ha-1) compared to DAP (av. = 43.7 kg P2O5 ha-1). The latter differences are of statistical significance. Individual biostimulants and a combination of multiple biostimulants rarely resulted in significantly higher yields, with the exception of some combinations
with humic substances and mycorrhiza in individual years. The influence of the climatic conditions in each of the years was higher than the influence of the biostimulants. However, average increases in yield over three years would be economically beneficial for farmers in the case of the applied humic
substances product and mycorrhiza. An adequate alternative to DAP was found in the form of a Preduced microgranular fertilizer from Startec.

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.

abstract = "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  - Environmental problems related to the application of herbicides are causing a concern due to their increasing presence in soil, groundwater and surface water. Numerous methods have been developed in order to reduce herbicide mobility and protect natural water resources. The results presented in this paper show the interaction of herbicide S- metolachlor with inorganic and organically modified montmorillonite from Bogovina (Boljevac municipality, Serbia). Clay sample from Bogovina represents Ca-Na montmorillonite with a small amount of quartz, cristobalite and carbonate minerals. Organic montmorillonites were obtained after modification with different concentrations of organic complex (HDTMA and PTMA), whereas inorganic modification was performed with 1M NaCl solution. The interaction between minerals and herbicide was monitored using infrared spectroscopy. IR bands observed in the inorganic modified montmorillonite (Na-montmorillonite) are typical for smectites with a high Al content in the octahedron position.
The intercalation of HDTMA+ cations into the interlayer space produces redshift of the IR bands that originate from the vibrations of the adsorbed water, as a consequence of the hydrogen bond strength reduction in HDTMA-montmorillonite. Also, the intensity of these bands decreases significantly with the increasing concentration of HDTMA+ cation. All these changes are related to the decreasing of the water content in the interlayer space by increasing the content of HDTMA. The occurrence of the stretching CH2 vibrations is generally the main difference in the spectrum of HDTMA modified montmorillonite in comparison with the spectrum of inorganically modified montmorillonite. The wavenumber, intensity and width of these bands are sensitive to conformation in hydrocarbon chains. After the organic modification of the montmorillonite with the PTMA complex, stretching vibrations of the phenyl ring occurred.
Analysis of FTIR spectroscopy data showed that the hydrogen bond is one of the most important mechanisms that occur between Na-montmorillonite and S-metolachlor. Comparing the FTIR spectra of herbicides before and after the sorption, it can be concluded that the carbonyl group participate in the binding process. Sorption of S- metolachlor on HDTMA-montmorillonites causes the redshift of the C=O absorption band. Shifting to lower wavenumbers and joining with the deformation vibration band of water indicates that the C=O group participated in the formation of a bond with the montmorillonite. Sorption of S-metolachlor molecules on PTMA-montmorillonite takes place through the interaction between the aromatic benzene ring of S-metolachlor and the aromatic benzene ring of the organic complex (π-π bonds). Also, the formation of a hydrogen bond occurs between the molecules of S-metolachlor and the molecules of water that are in the interlayer space and/or oxygen on the surface of the tetrahedral sheet of the montmorillonite.

se nekada javljaju dileme kome tipu zemljišta pripadaju neke zemljišne jedinice, jer ne postoje
direktno utvrđeni kvantitativni pokazatelji koji razgraničavaju pojedine zemljišne jedinice ili

okviru šire studije, u podnožju krečnjačkog masiva planine Vukan, na potesu Veliko polje,
otvoreno je 42 zemljišna profila. Karbonatna skeletna zemljišta na jedrim krečnjacima sa
izraženim humusno-akumulativnim horizontom su identifikovana na oko 40% područja, odnosno
na 15 otvorenih profila.
MATERIJAL i METOD: Istraživanja su obuhvatala otvaranje profila zemljišta do 90 cm
dubine, odnosno do dubine matične stene, detaljan opis zemljišta na terenu, kao i uzimanje uzoraka
zemljišta u narušenom i nenarušenom stanju za laboratorisjke analize, kao i klasifikaciju
zemljišta prema domaćem i međunarodnom sistemu (WRB) klasifikacije.
REZULTATI i ZAKLjUČCI: Zemljišta su klasifikovana kao koluvijalni kalkomelanosoli.
Koluvijalni kalkomelanosoli su identifikovani na nadmorskoj visini od svega 185–210 m, što je
neuobičajeno za ovaj tip zemljišta. Iz istog razloga i njegove ostale fizičko-hemijske osobine
odstupaju od do sada opisanih koluvijalnih kalkomelanosola. Teren pod kalkomelanosolima se
koristi kao ekstenzivni pašnjak, dominantan nagib terena je 2–5%, a skeletnost površine iznosi
10–80% u zavisnosti od profila. Građa većine ispitivanih profila je A – R. Boja humusnoakumulativnog horizonta je veoma tamna braon i veoma tamna braon siva, nešto svetlija od
tipičnih crnica. Koluvijalni kalkomelanosoli se odlikuju dubinom 40–70 cm, a sadržaj skeleta
se povećava sa dubinom. Veličina skeleta je 2–200 mm, a oblik je nepravilan – uglast. Struktura
zemljišta je umereno izražena, dominantna veličina zrnastih agregata je 1–5 mm. Veoma visok
sadržaj kalcijum-karbonata u supstratu, 90–99% u 12 profila ukazuje na jedre krečnjake. Skelet je
po dubini zemljišnog profila i karbonatan i beskarbonatan, što ukazuje na koluvijalne procese u
prošlosti. Intenzivno hemijsko raspadanje ovog skeleta je dovelo čak i do pojave
pseudomicelarnog potpovršinskog horizonta koji se nalazi iznad matične stene u dva profila,
kao i do pojave karbonatnosti zemljišne mase u horizontima, što nije tipično za kalkomelanosole.
Zemljišta nisu klasifikovana kao rendzine, jer postojeća nacionalna klasifikacija ne prepoznaje

AB  - INTRODUCTION and OBJECTIVES: Soil is one of the most important natural resources. Measurement of natural radioactivity in soil is very important to determine the amount of change of the natural background activity with time as a result of any radioactivity release. Gacko field is a karst field and is virtually the only oasis of arable land in the region studied. Nevertheless, nothing significant has been done in this area over the past decade to protect land resources from damage and permanent destruction. Coal mine and thermal power plant in Gacko field is a very important industrial facility.
MATERIAL and METHOD: The content of radionuclides of the soil was examined at Gacko area, slag, ash and mullock dumps in the thermal power plant Gacko and soils of dumps in the process of recultivation.
Soil samples were collected in 2010/2019 at more locations in eastern part of the Republic of Srpska. After removing the stones and vegetation, all soil samples for Gamma Spectrometric measurements dried up to 105 0C, sieved, placed in the plastic 500 mL Marinelli beakers and left for four weeks to reach radioactive equilibrium.
RESULTS and CONCLUSIONS: The results of gamma emitters spectrometry indicate that the concentrations of natural radionuclides are of the same order of magnitude, as in power plants in other countries. The results point to the necessity of regular monitoring of radioactivity in eastern Herzegovina in order to assess the impact of the technologically increased natural radioactivity.At the same time, the obtained results represent the initial basedata based on which could be predicted level radioactivity since
such studies have so far not been carried out in the Republic of Srpska.

AB  - УВОД и ЦИЉЕВИ: Хидрауличка својства земљишта (ХСЗ) контролишу кретање и складиштење воде и хранљивих материја у земљишту и на тај начин утичу на широк спектар биогеохемијских процеса и услуга екосистема. За потребе хидролошког моделирања, углавном се карактеришу као константне вредности, на пример, засићена хидраулича проводљивост (Ксат), капацитет инфилтрације или пољски водни капацитет (ПВК). Ипак, добро је познато да су многа физичка и хемијска својства земљишта променљива у простору и времену. Могући разлози за то су биолошка активност земљишта, процеси повезани са мразом, утицај ветра преко корена биљака, обрада земљишта, испаша и друго. Стога се може очекивати да ХСЗ и хидролошка својства земљишта такође варирају постепено. Овај рад анализира варијабилност ХСЗ и хидролошких својстава у површинском слоју (0–15 цм) бескарбонатне, прашкасто-глинасте ливадске црнице (Fluvisol) у долини Колубаре изазвану вишегодишњим (> 100 година) различитим коришћењем земљишта.
МАТЕРИЈАЛ и МЕТОД: На блиском међусобном растојању идентификоване су две различите намене земљишта (мешовита широколисна листопадна шума и пашњак). Пашњак је кошен углавном само једном у касно пролеће, а касније су само повремено напасане краве (2–3 краве ха–1) и овце (8–10 оваца ха–1). Унутар сваког начина коришћења земљишта изабране су три локације на којима је спроведен исти програм мерења густине сувог земљишта (ρb), Ксат, капацитета инфилтрације, ПВК и ретенционе криве стандардним међународно признатим методама. Користећи овај план истраживања, претпоставили смо да се могу идентификовати систематске разлике у ХСЗ и хидролошким својствима земљишта у погледу коришћења земљишта.
РЕЗУЛТАТИ и ЗАКЉУЧЦИ: Резултати показују да коришћење земљишта има значајан утицај на испитивана својстава земљишта. Идентификоване разлике су статистички значајне са вероватноћом од 5%. Уочено је повећање ρb од шуме (0,99 г цм–3) до пашњака (1,49 г цм–3) у површинском слоју истраживаног земљишта, што је у складу са налазима из литературе. Као што се и очекивало, Ксат је већа у шуми (>100 м дан–1) у п оређењу с а п ашњаком ( 0,30 м д ан–1). Капацитет инфилтрације за шумско земљиште је знатно већи него за пашњак, за шта се може претпоставити да је последица веће вредности Ксат површинског слоја земљишта. Што се земљиште интензивније користи (пашњак > шума), мање воде се складишти у земљишту на одређеном притиску. Шумско земљиште је показало знатно већи просечни садржај воде (46% запреминска) него пашњачко (38%) земљиште на pF 2,5, који је коришћен као замена за пољски водни капацитет. Иста структура резултата је
пронађена и за друге pF вредности. Отуда се може претпоставити да померање криве задржавања воде узрокује смањење приступачне воде за биљке. Закључно, ово истраживање указује да коришћење земљишта има важан утицај на хидрауличка и хидролошка својства земљишта. Интензивнија пољопривредна употреба, као што је пашњак у овој студији, повећава ρb и смањује Ксат и садржај воде која је приступачна биљкама (смањен ПВК). Ово је углавном због сабијања земљишта при прекомерној испаши која доводи до губитка макропора. Запажања дата у овом истраживању имају важан утицај на разумевање хидролошких процеса и на разраду хидролошких модела. Они често узимају у обзир малу просторну варијабилност својстава земљишта, али њихова параметризација не зависи од коришћења земљишта. Ово истраживање је показала да ова претпоставка не важи и да се не може тек тако занемаривати.

AB  - Нормализована разлика вегетационог индекса (NDVI) је индикатор здравља вегетације, али и промене земљишног покривача на основу рефлексије одређених опсега у електромагнетном спектру.

AB  - Extreme weather and climate events over the past years have been bringing damage and
losses to agricultural production in Serbia.
As a part of the development of the National climate change adaptation plan, weather and
climate events and extremes that may significantly influence the growth of agricultural plant,
their quality and yields, were defined as a first step in the climate change risk assessment
within the agriculture sector. Such events included: high summer temperature, low winter
temperature, spring frost, drought, intense precipitation, floods, hail and storms, but also
slow-onset changes such as inter annual redistribution of precipitation and rising air
temperatures. Based on the selected potentially dangerous phenomena, bioclimatic indices
were formulated for various fruit species, grapevine, strategically important field crops,
meadows and pastures.
The degree of exposure to selected weather and climate events was assessed for the past,
present and future, based on the analysis of daily data on temperature and precipitation from
the eOBS gridded observations dataset (2000-2019) and projections of 8 regional climate
models under the RCP8.5 greenhouse gases emission scenario, for the periods 1986-2005,
2021-2040, 2041-2060, 2081-2100. The vulnerability assessment was done for the
administrative districts and the entire territory of the Republic of Serbia based on the
valuation of the severity of socio-economic consequences that considered events might have.
The risk assessment was done combining the estimated levels of exposure and vulnerability.

AB  - Fruit and vine production in the territory of the Kolubara District encompasses 15,685 ha, which accounts for around 15.3% of the total plant production. When it comes to fruit plantations, plums are the most represented (70%), while peaches and strawberries account for only 0.3%. The aim of this research was to determine the seasonal water requirements of fruit trees in climate change condition, to find out wheter will be changes in irrigation requirement. In addition, the paper includes the analysis of water requirements for the future periods in order to enable producers to adapt their agronomy practices and growing systems to the forthcoming conditions. FAO methodology (FAO Irrigation and Drainage Paper No. 56), was used to estimate the evapotranspiration, effective precipitation, crop evapotranspiration and water deficit, for 8 groups of fruit plantations: (I) apples, pears, plums, quinces, walnuts and hazels – the orchard without grass cover; (II) apples, pears, plums, quinces, walnuts and hazels – grassy orchard; (III) apricots and peaches – the orchard without grass cover; (IV) apricots and peaches – grassy orchard; (V) sweet cherries and sour cherries - the orchard without grass cover; (VI) sweet cherries and sour cherries - grassy orchard; (VII) strawberries, raspberries, blackberries and blueberries and (VIII) grapevine. The fruit plantations were categorised into the above-mentioned eight groups according to the length of the vegetation period and the crop coefficient values. The observed period from 2000–2019 and two future periods (2021–2040 and 2041–2060) were analysed. The climate data for the reference 2000–2019 period were obtained from the meteorological station in Valjevo. Data for the future climate were obtained using 8 climate models for the RCP 8.5 climate scenario. The paper provides the results obtained as the median of the calculations for eight climate models. The evapotranspiration value varies from 438.6, 429.0 and 440.5 mm for fruit trees from group V, respectively, to 892.2, 857.5 and 884.6 mm for fruit trees belonging to group II, with the average values of 596, 577.9 and 595.4 mm for the reference period, the future 2021–2040 and 2041–2060 periods, respectively. The seasonal water deficit varies from 88.0, 41.3, and 90.6 mm for grapevine (group VIII) to 405.6, 352.3, and 405.3 mm for fruit trees from group II, with the average values of 224.4, 198.7 and 245.3 mm for the reference period, and future 2021–2040 and 2041–2060 periods, respectively. The results of this research indicate that no significant differences in the water requirements between the future periods and the reference period.

AB  - Soil pore characteristics can have great impact on plant growt and environment. A study was conducted to evaluate the efects of different land use on porosity, pore size distribution (PSD) and soil water retention (SWR) of Fluvic Phaeozem in the Kolubara River valley, Serbia. The land use treatments included: natural forest, native meadow, and arable land managed in the same way for more than 100 years. Disturbed and intact soil samples were collected from three soil profiles at each of the three different land use types from depths of 0–15, 15–30 and 30–45 cm. The capillary rise equation was used to estimate effective pore sizes from water retention measurements. Pressure cells are used to mesure water retention in the water potential range from –33 to –1500 kPa. The bulk density (BD) was significantly (P < 0.05) larger for meadow (1.48–1.49 g cm–3) and arable land (1.28–1.42 g cm–3) than forest (0.99–1.29 g cm–3) at the top 30 cm of soil. There was no significant difference in BD between meadow and arable land in the subsurface soil layer (15–30 cm). Depending upon the increases in BD and disruption of pores by mowing and tillage management, total porosity decreased accordingly in meadow and arable land. Land use had significant effect on PSD. Volume of macropores (> 30 μm) were significantly higher for forest (10.93–16.19%) than meadow (4.77–5.74%) and arable (4.83–7.81%) land for 0–30 cm soil layer. Among the diferent land use types, forest and arable land had significantly higher mesopores (30–3 μm) volume compared with meadow. Mowing and tillage management significantly decreased volume of micropores < 3 μm diameter size at the 0–30 cm soil depth. The results showed that in the 0–0.15 m and 0.15–0.30 m depth soil layers, forest soils showed a significantly higher the available water capacity compared to meadow and arable lands. The S-index also detected clear differences among land uses. In this study, the soil water retention data are well described by the van Genuchten model. In conclusion, our results showed that total porosity, PSD, and moisture retention significantly changed because of the different management systems in the top 30 cm of soil, which can potentially influence crop yields and ecosystem function

Volume of macropores (> 30 μm) were significantly higher for forest (10.93–16.19%) than meadow (4.77–5.74%) and arable (4.83–7.81%) land for 0–30 cm soil layer. Among the diferent land use types, forest and arable land had significantly higher mesopores (30–3 μm) volume compared with meadow. Mowing and tillage management significantly decreased volume of micropores < 3 μm diameter size at the 0–30 cm soil depth. The results showed that in the 0–0.15 m and 0.15–0.30 m depth soil layers, forest soils showed a significantly higher the available water capacity compared to meadow and arable lands. The S-index also detected clear differences among land uses. In this study, the soil water retention data are well described by the van Genuchten model. In conclusion, our results showed that total porosity, PSD, and moisture retention significantly changed because of the different management systems in the top 30 cm of soil, which can potentially influence crop yields and ecosystem function",

AB  - Soil pore characteristics can have great impact on plant growth and environment. A study was conducted to evaluate the efects of different land use on porosity, pore size distribution (PSD) and soil water retention (SWR) of Fluvic Phaeozem in the Kolubara River valley, Serbia. The land use treatments included: natural forest, native meadow, and arable land managed in the same way for more than 100 years. Disturbed and intact soil samples were collected from three soil profiles at each of the three different land use types from depths of 0–15, 15–30 and 30–45 cm. The capillary rise equation was used to estimate effective pore sizes from water retention measurements. Pressure cells are used to mesure water retention in the water potential range from –33 to –1500 kPa. The bulk density (BD) was significantly (P < 0.05) larger for meadow (1.48–1.49 g cm–3) and arable land (1.28–1.42 g cm–3) than forest (0.99–1.29 g cm–3) at the top 30 cm of soil.
