AB  - Despite presenting a practical approach for the characterization of the environmental risk of potentially toxic elements (PTEs) derived from steel production facilities, the analysis of the spatial distribution of bioavailable PTEs concentrations in the soil is frequently overlooked in the management of polluted sites. In this study, the diethylenetriaminepentaacetic acid (DTPA)-extractable forms of PTEs were investigated in soils surrounding the largest Serbian steel production plant. The correlation and geostatistical analysis indicated their pronounced variability suggesting the anthropogenic origin of most investigated elements, apparently from the steel production facility. The detailed visualization of variables and observations derived by self-organizing maps (SOMs) revealed the homologies in PTEs’ distribution patterns, implying the common origin of some elements. These observations were confirmed by principal component analysis (PCA) and positive matrix factorization (PMF). The аpplied approach supports a comprehensive assessment of contaminated sites' ecological and health risks and provides a basis for soil remediation. © 2023 The Authors

AB  - This study was conducted to compare soil particle density (rho (s)), soil total porosity (TP), liquid limit (LL), plastic limit (PL), and plasticity index, and their relations with soil organic matter (SOM), of non-carbonate silty clay Fluvisols under different land uses. Three neighboring land uses were studied: native deciduous forest, arable land, and meadow, managed in the same way for more than 100 years. Soil was collected from 27 soil profiles and from three depths (0-15, 15-30 and 30-45 cm). Land use caused statistically significant but different impacts on soil properties, particularly in the topsoil. The forest topsoil measured the lowest rho (s) and bulk density (rho (b)) but the highest SOM and soil water content at PL, compared to meadow and arable soil. Statistically significant linear relationship was observed with the SOM content and rho (s) (-0.851**), rho (b) (-0.567**), calculated TP (0.567**) and measured TP (-0.280**). There was a nonlinear relationship between SOM and LL (0.704**) and PL (0.845**) at the topsoil. The findings suggested that SOM content strongly affected rho (s), rho (b), TP, LL and LP. This regional study showed that the conversion of forestland into agricultural land without appropriate measures to conserve SOM leads to the degradation of physical and rheological soil properties.

AB  - The effects of long-term (>20 yr) grazing on the selected physical properties of a non carbonated silty-clay Fluvisols were studied in the region of the Kolubara Valley, Northwest Serbia. Two adjacent land-use types (native deciduous forest and natural pasture soils converted from forests for more than 20 years) were chosen for the study. Disturbed and undisturbed soil samples were collected from three sites at each of the two different land-use types from the depths of 0–15, 15–30 and 30–45 cm. In relation to the soil under native forest, soil organic matter content, total porosity and air-filled porosity were significantly reduced after long-term of grazing. The bulk density (0.99–1.48 g cm–3) and the saturated hydraulic conductivity (6.9.10–2–3.2.10–4 cm s–1) were significantly lower in forest compared to the adjacent pasture (ex-forest) soil (1.49–1.55 g cm–3 and 3.4.10–4–5.5.10–4 cm s–1, respectively). In addition, forest had significantly lower dry mean weight diameter (7.0–9.2 mm) and greater wet mean weight diameter (2.0–2.6 mm) for 0–45 cm depth compared with the pasture (8.8–9.4 mm and 1.8–2.3 mm, respectively). The decrease of soil organic matter content and reduction in aggregate stability under long-term grazing rendered the soil more susceptible to compaction. In conclusion, the results of this study indicate that removal of permanent vegetation in the conversion process from forest areas to pasture land may lead to loss of soil productivity and serious soil degradation. Obviously, there is a need for greater attention to developing sustainable land use practices in management of these ecosystems to prevent further degradation of pasture soils in the region.

AB  - Human activity can significantly alter land cover characteristics and subsequently hydrological and other processes in river basin. The aim of this study was to determine infiltration of surface (0-30 cm) sandy loamy Fluvisol under natural meadow vegetation and adjacent Fluvisol which is used more than 10 years as the arable soil, with similar conditions of pedogenesis in the Nišava River Valley, in the vicinity of Pirot (Serbia). The other conditions of pedogenes were similar. Measurement of infiltration was performed by double cylindrical infiltrometer. Three infiltration runs were carried out for each location. The results showed that the in the arable soil compared with meadow, constant (steady state) infiltration rate and cumulative infiltration were about 699% and 447% higher, respectively. The change in soil structure caused by loosening of the plowing layer because of tillage is the main factor causing the increase in infiltration of water into the soil after conversion of natural grassland to arable soil. These results can be used in predicting surface runoff, saturated hydraulic conductivity of the surface layers and groundwater recharge, and also in the development or selection of the most efficient methods of irrigation sandy loam soils.

U vezi s tim, obavljena su uporedna terenska istraživanja u cilju utvrđivanja infiltracije vode u površinskom horizontu (0-30 cm) bestrukturnog, peskovito-ilovastog, slabo humoznog distričnog fluvisola pod prirodnom livadskom vegetacijom i sličnog fluvisola koji se koristi više od 10 godina kao njivsko zemljište, u dolini reke Nišave, u okolini Pirota (Srbija). Ostali uslovi pedogeneze bili su im slični. Merenje infiltracije vršeno je pomoću duplih cilindričnih infiltrometara. Na svakoj lokaciji obavljena su po tri merenja infiltracionih karakteristika istraženih zemljišta. Rezultati su pokazali da su u obrađivanom zemljištu konstantna (ustaljena) brzina infiltracije i kumulativna infiltracija veće za oko 699%, odnosno 447% u poređenju sa prirodnom livadom. Promena građe zemljišta uzrokovana rastresanjem oraničnog horizonta pri obavljanju agrotehničkih operacija glavni je faktor koji je uzrokovao povećanje brzine infiltracije vode nakon prevođenja prirodnih livada u oranice.
