AB  - Part of Cu post flotation tailings of Serbia ZiJin Bor Copper, Serbia, was reclaimed by restoration of top soil with arable soils, and revegetation in 1991. Humic acids isolated from these Technosols were investigated to find out if their properties underwent any changes since reclamation. Two groups of control samples were used. Elemental composition (CHNS analysis) falls within the range of average soil humic acids. Humic acids belong to the type B pointing out to its lower humification degree (UV?Vis). Relative abundances of functional groups are ranged as follows: polysaccharide C ??aromatic C > carboxyl C > OH group > aliphatic C. Aromaticity indexes are low, 1.88? 3.25 (ATR-FTIR). Basic units at pH 10 are in the 11.7?26.8 nm range. Pronounced reaggregation (1462-?5218 nm) at pH 3 points out to less expressed humic acid sol stability, as well as to increase in aromatic condensation degree (dynamic light scattering). No significant changes have occurred in technosol humic acids since the recultivation, confirming stability of their properties over time (PCA). Nevertheless, humic acids from very strongly acidic Technosols show higher humifycation degree possibly originating from arable soils used in reclamation, but more likely from low soil pH and low litter input, results of unsuccessful reclamation.

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  - Liming is a common practice in the treatment of acidic and metal contaminated soils, aiming at pH regulation, enhancing of the nutrient availability and attenuation of trace metals mobility. Replacement of natural limestone with alternative soil alkalizers found among waste materials represents a step towards sustainable resource management and reduced waste storage. In this study, waste seashells (SW) and red mud (RM) were applied in different doses to the soil sampled in the vicinity of mining and smelting complex. The soil was characterized by acidic reaction (pH 4.93), increased Cu concentration (219.2 mg/kg) and a very low level of P-supply (3.61 mg P2O5/100 g). The study aimed to quantify and compare additive-induced effects onto soil physicochemical properties, the status of macronutrients and distribution of trace metals. Targeted effect on soil pH was achieved with SW dose of 0.3% and RM dose of 2%. RM was found to be a source of available P and gave rise to the available P concentrations in the soil. Medium level of P-supply (15.60 mg P2O5/100 g) was achieved with RM dose of 5%, however, the increase in soil salinity and total trace elements concentrations have become significant adverse effects at such dose. The decrease in the ion-exchangeable content of Cu and other trace metals was in correlation with the increase in soil pH after the treatments. Redistribution of metal cations was mainly directed to carbonate/acid soluble and Fe, Mn-oxide bonded fraction after SW addition. Even though trace metals concentration has increased in the soil after application of the RM, they were principally found in the residual fraction. The results emphasize low amounts of contained trace elements and lower doses for achieving targeted effects on pH and metal mobility as the main benefits of SW treatments. On the other hand, moderate and controlled use of RM may represent multiple benefits in terms of simultaneous pH regulation, P-supply, and reduced trace metals mobility. © 2019 Elsevier B.V.

AB  - To gain a better knowledge of mining areas and potential remediation processes, some characteristics (morphological, physical, chemical and microbiological) of soils formed on open-pit Cu mine waste (OPW) and Cu post-flotation tailings (PFT) dumps were investigated. Soil profiles and surface samples were studied. In general, the investigated soils are characterized by large proportion of coarse soil particles, degraded structure, low humus content, low pH, high As and Cu concentrations, and low soil microbial activity. In all investigated profiles there is no recognizable topsoil layer containing in situ formed humus probably due to soil age, lack of plant cover and organic litter, as well as other unfavorable soil conditions. The specificity of investigated soils is an irregular distribution of some soil characteristics (porosity, humus content, microbiological activity) over depth, which is a result of their technogenic origin. By establishing correlations between the studied surface sample parameters, using principal component analysis (PCA), poorer aggregate properties of PFT than of OPW soils were found, resulting most likely from aggressive mining, i.e., flotation processes. Both OPW and PFT soils compared with control natural soils are characterized by lower clay and humus content, and poorer aggregate properties.
