AB  - Closing the loop – An EU action plan for the circular economy identified the Fertilisers Regulation revision as a key legislative proposal to boost the market for secondary raw materials. The European Commission has adopted recently EU Fertilising Products Regulation EU 2019/1009 expanding its scope to secondary-raw-material-based products (from biogenic wastes and other secondary raw materials). During the industrial processing of sunflowers, sunflower husks used as alternative fuels resulting in the generation of waste ash. Sunflower ash is a known material as a good and cheap source of potassium. In present study the tested samples of ashes is characterized as a starting raw material for the producing fertilizers in an accredited and authorized Laboratory for fertilisers quality. The tested samples is not loaded with heavy metals and the risk of recycling contaminants has not been assessed. According to the content of available (water-soluble) elements, the content of soluble phosphorus and micronutrients is very low, while potassium is completely water-soluble (40 to 50% K2O m/m), therefore, the tested ashes can be regarded as a good raw material as a source of potassium component in the final product. The pH reaction of the samples is extremely alkaline, therefore it is necessary to neutralize pH reaction in the industrial processing of this raw material, or to restrict the final product for use on acid reaction soils.

AB  - Intensive crop cultivation systems require continuous monitoring of irrigation water quality as well as the control of physical and chemical soil properties. In view of the ongoing climate change and a dramatic decrease in soil organic matter content, the use of low quality irrigation water and its adverse effects on soil, cultivated plants and irrigation equipment must not be overlooked. The aim of this paper was to evaluate general quality of irrigation water from the different water intake sources in the Vojvodina Province. The paper presents the results of irrigation water quality, collected during 2018 and 2019. The research included 140 irrigation water samples obtained from three different intake structures which collect water from wells, canals or reservoirs. Water quality was assessed using the following parameters: pH value, electrical conductivity (EC), total dissolved solids (TDS), ionic balance, sodium adsorption ratio (SAR) and residual sodium carbonate (RSC) value. Water quality diagram given by the US Salinity Laboratory (USSL) and FAO guidelines for interpretation water quality for irrigation was used. Additionally, the Nejgebauer classification for irrigation water, developed specifically for the area of Vojvodina, was used as a third classification. Based on the results of mineralization of the irrigation water, the following values of the observed parameters were determined: average pH of the analyzed water samples were 7.89, ranged from 7.14 to 9.01, while electrical conductivity values ranged from 0.10 to 3.50 dS/m, with an average of 0.85 dS/m. TDS analysis resulted in a wide range of values, from 112 mg/l to 2,384 mg/l, with an average of 529,22 mg/l. SAR values varied between 0.04–16.52 with a satisfactory average of 1.97.  The USSL water classification produced similar results as FAO classification and RSC index <0, indicating that 57% of investigating samples are without concerns for irrigation use. Whereas, Nejgebauers classification and RSC index 0–1.25 shows that over 75% of analyzed samples are suitable and safe for irrigation and soil properties. Since the quality of irrigation water significantly affects plant productivity, as well as determines the chemical and physical properties of agricultural land, monitoring of water quality for irrigation is of high importance

U radu su prikazani rezultati kvaliteta vode koja se koristi za navodnjavanje, prikupljeni tokom 2018. i 2019. godine. Istraživanje je obuhvatilo 140 uzoraka vode iz razli­ čitih vodozahvata poreklom iz površinskih bunara, kanalske mreže i akumulacija za navodnjavanje. Za ocenu kvaliteta vode analizirani su sledeći parametri: pH vrednost, elektroprovodljivost (EC), suvi ostatak, jonski bilans, kao i koeficijent adsorpcije natrijuma (SAR) i vrednost rezidualnog natrijum-karbonata (RSC). Uobičajeno je da se za ovu namenu koristi i klasifikacija prema Američkoj laboratoriji za slatine (USSL) kao i FAO procena kvaliteta vode za navodnjavanje.

Na osnovu rezultata mineralizacije vode za navodnjavanje, utvrđene su sledeće vrednosti posmatranih para­ metara: prosečno izračunata pH vrednost analiziranih voda iznosila je 7,89 (min=7,14, max=9,01), vrednosti elektroprovodljivosti kretale su se u opsegu od 0,10 do 3,50 dS/m, sa prosečnom vrednošću 0,85 dS/m. U odnosu na vrednosti suvog ostataka, ispitivane vrednosti kretale su se u širokom opsegu, od 112 mg/l do 2.384 mg/l, s prosečnom vrednošću 529,22 mg/l. SAR vrednosti varirale su u opsegu 0,04–16,52 i zadovoljavajućim prosekom od 1,97. Klasifikacija prema Američkoj laboratoriji za slatine (USSL) pokazuje slične rezultate kao FAO klasifikacija i RSC indeks <0, ukazujući na to da 57% istraživanih uzoraka nije zabrinjavajuće za upotrebu u navodnjavanju. Nejgebauerova klasifikacija i RSC indeks 0–1,25 pokazuju da je preko 75% analiziranih uzoraka pogodno i za navodnjavanje i sigurno za očuvanje fizičko hemijskih svojstava zemljišta. Budući da kvalitet vode za navodnjavanje značajno utiče na produktivnost biljaka, kao i da značajno može uticati na hemijske i fizičke osobine poljoprivrednog zemljišta, praćenje kvaliteta vode za navodnjavanje od izuzetne je važnosti.

AB  - Whole kernels of cereals are the most important source of magnesium. This mineral has several positive effects on human health. However, the human body cannot absorb 100% of magnesium from plant sources during digestion. Additionally, the wheat flour milling process usually produces refined flour with a substantially lower content of magnesium. The aim of this study was to examine the effect of milling of two wheat cultivars on total and soluble magnesium distribution in milling fractions, with the purpose of creating wheat bread with a precisely defined magnesium content. Ash content, thousand grain weight (TGW), and kernel size were analysed in five wheat cultivars. Two most statistically distinguished wheat cultivars according to these analyses (Moma and Todorka) were milled in a laboratory mill to gain as many flour frac-tions as possible (eleven). Magnesium was extracted from the flour and its content was measured by inductively coupled plasma. The results showed that the level of soluble magnesium in refined white flours (T-500 with ash content between 0.46-0.60d. m.%) is approximately 17% and is available for uptake in the human body. Also, by milling the Moma cultivar in an industrial mill with a capacity of 100 t per day gave 6.6 t more brown flour (T-1000 with ash content between 1.05-1.15 d.m.%) than the Todorka cultivar. Furthermore, the daily consumption of brown bread (produced from brown flour) in Serbia would satisfy about 60% of the daily magnesium requirements.

AB  - Mercury (Hg) is a heavy metal, designated as a pollutant in the environment, due to its
harmful effects on biota. Mercury pollution is a significant global concern, not only due to its
increased levels in the environment, but also due to its toxic effect on human health across the
food chain. The aim of this study was to determine the content of Hg in agricultural soils and
main field crops. Total number of 84 bulked soil samples were taken (0-30 cm depth) from
agricultural land. At the same plots, 84 plant crops (11 species – used as food and feed) were
taken during the vegetation season 2018. The samples were analyzed for total Hg content
using Direct Mercury Analyzer DMA 80 Milestone. The obtained results of Hg content in soil
were within interval 0.003-0.37 mg kg-1
. The average concentration of Hg was 0.08, with
median 0.06±0.06 mg kg-1
. Obtained values of Hg in soils were below maximum allowable
concentration (MAC) and this interval is complied with the most cited range in soils up to 1
mg kg-1 without known nearby contamination sources. It was found that Hg content is
positively correlated with pH value, slit soil fraction, and CaCO3. The obtained results of Hg
content in plant – field crops, were within interval 0.0001-0.9087 µg kg-1
. Obtained maximum
value is still far lower than MACs for feed and food. According to the average Hg content in
plant species, obtained results were classified from highest to lowest, respectively: bean,
alfalfa, maize, soybean, rapeseed, sunflower, barley, pepper, wheat, rye and tomato.

AB  - Red clover (Trifoilum pratense L.) is considered as one of the most important legumes, and today is the second most important, after alfalfa. Production of high-quality feed from red clover may be affected, among other things, the increased concentration of heavy metals in some agricultural areas, primarily due to anthropogenic influences. The aim of this study was to determine the level of nickel in red clover grown on soils with different content of nickel, in order to obtain information on safety of these nutrients. The examination was conducted on four types of soil: chernozem, vertisol, eutric cambisol and humofluvisol. Sampling of soil and plant material was carried out during May 2011, in the second year of red clover production. The total content of nickel in soil samples, at a depth 0.30 cm, was in the range 3.36-129.67 mg/kg. Maximum permitted level of nickel in soil is 50 mg/kg. The content of nickel in red clover was in the range 0,41- 6,87 mg/kg, which is below the critical and toxic concentrations to plants. It was concluded that the accumulation of heavy metals in plants did not depend only on the total content in soil, but also the affinity of the plant, and individual and interactive effects of various soil properties. It is necessary to further control of nickel in contaminated area, in order to prevent his entry into 
the food chain and provide safety food.
