AB  - The mobility (fractionation) of rare earth elements (REEs) and their possible impacts on ecosystems are still relatively unknown. Soil samples were collected from two sites in central Serbia, an unpolluted mountain region (site 1) and a forest near a city (site 2). In order to investigate REE fractions (acid-soluble/exchangeable, reducible, oxidizable, and residual) in soils, BCR sequential extraction was performed. Additionally, the content of REEs was also determined in stipes and caps of the mushroom Macrolepiota procera, growing in the observed sites. Sc, Y, and lanthanide contents were determined by inductively coupled plasma mass spectrometry (ICP-MS), and results were subjected to multivariate data analysis. Application of pattern recognition technique revealed the existence of two distinguished clusters belonging to different geographical sites and determined by greater levels of Sc, Y, and lanthanides in Goč soil compared to Trstenik soil. Additionally, PCA analysis showed that REEs in soil were concentrated in two groups: the first consisted of elements belonging to light REEs and the second contained heavy REEs. These results suggest that the distribution of REEs in soils could indicate the geographical origin and type of soil. The bioconcentration factors and translocation factors for each REE were also calculated. This study provides baseline data on the rare earth element levels in the wild edible mushroom M. procera, growing in Serbia. In terms of bioconcentration and bioexclusion concept, Sc, Y, and REEs were bioexcluded in M. procera for both studied sites.

AB  - The main soil properties, concentrations of selected elements (As, Cd, Cr, Cu, Fe, Mn, Ni, Pb, and Zn), and the chemical speciation of each element were determined in urban soil samples taken from urban parks in four Serbian cities (Belgrade, Panevo, Obrenovac, and Smederevo) exposed to different sources of pollution. Pollution indices (PI, PIN) and factors (MF, ICF, GCF) also were evaluated. The study revealed As and Cd concentrations below the detection limit, whereas the content of Cr, Cu, Fe, Mn, Ni, Pb, and Zn at some sites exceeded the limits established by local regulations, as well as the background values, which may represent an environmental threat. Sequential extraction results show that Fe, Cr, Cu, and Ni were predominantly in the residual fraction at most sites; however, Ni from Panevo and Smederevo also was bound to the reducible fraction. The presence of Pb at all sites and Zn in Smederevo and Belgrade was mainly associated with the reducible and residual fractions. The highest Mn content was found in the reducible fraction, followed by the acid soluble/exchangeable and residual fractions. Based on the obtained indices and factors, the overall soil status at the selected sampling sites was found to range from the warning limit to slightly polluted, whereby Smederevo had the highest risk, and Panevo and the control site the lowest risk of contamination by toxic metals.

AB  - Plant available arsenic (As) is not defined by its total content but by the various forms in soil. The aims of this study were to determine the amounts of As phases in soils extracted in the vicinity of the antimony mines; to study soil surface processes affecting formation of most mobile phases of As and the identification of sources of As phases in C soil horizon. Five fractions of soil As were determined by sequential extraction analyses (As F1, As F 2, As F 3, As F 4 and As F 5) in A and C horizons. The identification of the origin of As fractions were made by mean of principal component analyses (PCA) including Pearson correlations. The amount of the most mobile forms of As (As F1 and F2) was below 1%. The content of As F1, As F2 and As F4 decrease with soil depth, while aqua regia As and phases F3 and F5 increase with depth. Principal component analyses (PCA) showed that the content of As F2 is affected by anthropogenic factor and the content of As F4 by biological factor. In C horizon, As F2 and F4 are influenced by the leaching processes in soil. Arsenic F5 is bound to sediment rocks. The soil surface processes increases the availability of As in soil. The most mobile forms of As were found in deeper soil horizon that is due to the leaching of As with water from biological sources. The content of semi available phase of As F3 increases with depth, with stronger bounds due to the linkage to the amorphous Fe hydroxides.

AB  - We studied the effect of liming and P fertilization of extremely acid soil (accidently acidified by sulfidic mining waste) on P availability and the subsequent adaptive responses of wheat roots. The wheat plants were grown in rhizoboxes allowing precise sampling of rhizosphere and bulk soil for sequential extraction of P fractions and determination of exchangeable Al. Root exudates were collected by pieces of paper for electrophoresis and subjected to HPLC analysis. Expression of organic anions and P-i transporter genes was analyzed by a real-time quantitative PCR. The concomitant application of lime with P fertilization increased the concentrations of plant-available P fractions in both rhizosphere and bulk compartments. The applied soil amendments strongly affected plant growth, biomass partitioning and shoot P accumulation. Liming enhanced root exudation of citrate in P unfertilized plants, while the high malate efflux was maintained until both P deficiency and Al toxicity were eliminated by the amendments. We showed the importance of liming for recovering of P acquisition potential of wheat roots, which can be strongly impaired in acid soils. Our results clearly demonstrated that P-deficient roots not subjected to Al stress in the limed soil can maintain high efflux of malate and even increase efflux of citrate along with the enhanced expression of related anion transporters (TaMATE1 and TaALMT1).

AB  - Irreplaceability of phosphorus as a necessary macroelement in crop production is due to limited resources and costly processing of ores and immobilization in soil, which force for seeking an alternative sources or the use of waste materials. In this paper, the waste aluminum phosphate from pharmaceutical factory used as phosphate fertilizer and its effects were compared with other phosphorus fertilizers (superphosphate and rock phosphate). Except the analysis of available phosphorus (AL-method) the sequential extraction of phosphorus (modified Chang and Jackson) and sequential extraction of aluminum (modified Tessier) were performed. The experimental plant was mustard (Sinapis alba). The pot experiment was carried out on two soil types: Stagnosol and Vertisol. Application of phosphorus with aluminum phosphate had the same effect as the application of other phosphatic fertilizers in both soil types. In Stagnosol Al-phosphate directly influenced the increase in plant fresh weight by 39% and dry weight by 43% compared to the control, and also decreased the content of mobile Al for 40% and Pb for 47% in plant biomass. Based on these results, the use of waste aluminum phosphate has a potential to be used as a phosphorus fertilizer under given conditions.

AB  - The changes in inorganic and organic phosphorus (P) fractions of soil resulting from long-term fertilization (40 years) were investigated. In order to improve understanding of the sink and sources of phosphorus, P-fractions were extracted from soil samples from depths of 0-30 and 30-60 cm with different amounts of monoammonium-phosphate (MAP) and then determined. The studied soil was of the Stagnosol type. Phosphate fertilizer was applied in 26, 39 and 52 kg P ha(-1) amounts during a period of 40 years. Samples were subjected to sequential extraction according to a modified Chang and Jackson method and the Community Bureau of Reference (BCR) sequential extraction procedure in order to extract different forms of phosphorus. The certified reference material CRM 684 (river sediment extractable phosphorus) was used to confirm the accuracy of the instrument and of both employed methods. Furthermore, the association of phosphorus with substrates was provided by comparison of the results of sequential methods of phosphorus species with the sequential extraction of metals (Fe, Al, Mn and Ca). The results of continuous fertilization during 40 years indicated increases of all forms phosphorus in the soil except of phosphorus bound to calcium and organic phosphorus. Application of higher amounts of P-fertilizer resulted in the dominance of the Al P fraction in the studied soil, which indicated that this fraction was the most responsible for the migration of phosphorus along the soil profile.
AB  - U ovom radu ispitivane su promene u frakcijama neorganskog i organskog fosfora (P) u zemljištu koje su izazvane 40 godišnjim đubrenjem amonijum-fosfatom (MAR). Đubrivo je dodavano u količinama od 26, 39 i 52 kg P po hektaru zemljišta. U cilju praćenja mobilnosti fosfora, ekstrahovane su fosforne frakcije sa dve različite dubine zemljišta: površinski sloj od 0-30 cm i dubina od 30-60 cm. Tip ispitivanog zemljišta je Stagnosol. Uzorci su u cilju ekstrahovanja različitih oblika fosfora podvrgnuti sekvencijalnoj ekstrakciji i to na dva načina: prema modifikovanoj Chang i Jackson metodi i BCR metodi. Sertifikovani referentni materijal CRM 684 (rečni sediment) je korišćen za praćenje tačnosti obe korišćene metode. Osim toga je proučeno vezivanje fosfora sa supstratima (Fe, Al, Mn i Ca) koji su ekstrahovani sekvencijalnom ekstrakcijom metala. Rezultati ukazuju da kontinualno 40 godišnje đubrenje dovodi do povećanja sadržaja svih oblika fosfora u zemljištu osim fosfora koji je vezan za kalcijum i organskog fosfora. Primenom veće količine fosfornog đubriva dolazi do dominacije frakcije fosfora vezanog za aluminijum u ispitivanom zemljištu što ukazuje da je ta frakcija najodgovornija za migraciju fosfora kroz zemljište.

abstract = "The changes in inorganic and organic phosphorus (P) fractions of soil resulting from long-term fertilization (40 years) were investigated. In order to improve understanding of the sink and sources of phosphorus, P-fractions were extracted from soil samples from depths of 0-30 and 30-60 cm with different amounts of monoammonium-phosphate (MAP) and then determined. The studied soil was of the Stagnosol type. Phosphate fertilizer was applied in 26, 39 and 52 kg P ha(-1) amounts during a period of 40 years. Samples were subjected to sequential extraction according to a modified Chang and Jackson method and the Community Bureau of Reference (BCR) sequential extraction procedure in order to extract different forms of phosphorus. The certified reference material CRM 684 (river sediment extractable phosphorus) was used to confirm the accuracy of the instrument and of both employed methods. Furthermore, the association of phosphorus with substrates was provided by comparison of the results of sequential methods of phosphorus species with the sequential extraction of metals (Fe, Al, Mn and Ca). The results of continuous fertilization during 40 years indicated increases of all forms phosphorus in the soil except of phosphorus bound to calcium and organic phosphorus. Application of higher amounts of P-fertilizer resulted in the dominance of the Al P fraction in the studied soil, which indicated that this fraction was the most responsible for the migration of phosphorus along the soil profile., U ovom radu ispitivane su promene u frakcijama neorganskog i organskog fosfora (P) u zemljištu koje su izazvane 40 godišnjim đubrenjem amonijum-fosfatom (MAR). Đubrivo je dodavano u količinama od 26, 39 i 52 kg P po hektaru zemljišta. U cilju praćenja mobilnosti fosfora, ekstrahovane su fosforne frakcije sa dve različite dubine zemljišta: površinski sloj od 0-30 cm i dubina od 30-60 cm. Tip ispitivanog zemljišta je Stagnosol. Uzorci su u cilju ekstrahovanja različitih oblika fosfora podvrgnuti sekvencijalnoj ekstrakciji i to na dva načina: prema modifikovanoj Chang i Jackson metodi i BCR metodi. Sertifikovani referentni materijal CRM 684 (rečni sediment) je korišćen za praćenje tačnosti obe korišćene metode. Osim toga je proučeno vezivanje fosfora sa supstratima (Fe, Al, Mn i Ca) koji su ekstrahovani sekvencijalnom ekstrakcijom metala. Rezultati ukazuju da kontinualno 40 godišnje đubrenje dovodi do povećanja sadržaja svih oblika fosfora u zemljištu osim fosfora koji je vezan za kalcijum i organskog fosfora. Primenom veće količine fosfornog đubriva dolazi do dominacije frakcije fosfora vezanog za aluminijum u ispitivanom zemljištu što ukazuje da je ta frakcija najodgovornija za migraciju fosfora kroz zemljište.",
