Abstract Aim The study was undertaken to determine the effect of amendments used in remediation of cobalt-contaminated soil on the macroelement content of all organs of spring barley (the main crop) and white mustard (the after-crop). Methods In the experiment, six blocks were selected: without amendments; with manure (bovine, granulated); clay; charcoal; zeolite; and with calcium oxide (50%). In each of the blocks, increasing doses of cobalt were applied: 0, 20, 40, 80, 160, and 320 mg kg−1 of soil. Results Cobalt-contaminated soil and amendments application had a significant effect on macroelement content of all organs of both plants. Conclusions In blocks without amendments, 80 mg Co kg−1 contributed the most increase in nitrogen, sodium, and calcium contents of both organs of spring barley. Cobalt-contaminated soil increased content of all macroelements in white mustard organs. Application of amendments to soil had strong impact on phosphorus, sodium, and calcium contents of organs of both plant species, compared to the control block (without amendments). Among the amendments, manure had the greatest effect on the content of macroelements in plants. Manure increased phosphorus, potassium, and sodium contents of all organs of both plants. The optimal content of macroelements is extremely important for the growth and development of plants, especially on soils contaminated with trace elements, including cobalt.

Positive Effect

This study was undertaken to determine the effects of various substances on soil contaminated with cobalt (Co) on the mass and content of cobalt in the main crop—spring barley (Hordeum vulgare L.)—and the after-crop—white mustard (Synapis alba L.). Manure, clay, charcoal, zeolite, and calcium oxide were used for phytostabilization. Cobalt was applied in the form of CoCl2 in doses of 0, 20, 40, 80, 160, and 320 mg/kg soil. Amendments in the form of manure, clay, charcoal, and zeolite were applied in an amount of 2% in relation to the weight of the soil in a pot, with calcium oxide at a dose of 1.30 g CaO/kg of soil. The highest cobalt doses resulted in a significant reduction in yield of both plants and in tolerance index for cobalt. Increasing contamination of soil with cobalt resulted in a major and significant increase in its content in plants and a reduction in cobalt translocation factor in both plants. Amendments used in phytostabilization had a significant effect on growth and development of oat and content of cobalt in plants. The strongest effect on the yield of above-ground parts was exerted by manure (both plants) and calcium oxide (white mustard), while the strongest effect on weight of roots was exerted by calcium oxide (both plants) and zeolite (white mustard). The addition of manure, zeolite and calcium oxide to soil caused an increase of the tolerance index for both plants, while the addition of clay only had a positive effect for white mustard. All substances used in phytostabilization (except zeolite) decreased cobalt content of roots, and manure and calcium oxide in above-ground parts of spring barley; manure and zeolite only in above-ground parts, and calcium oxide in both organs of white mustard. Most of them also reduced bioconcentration of cobalt in above-ground parts, calcium oxide decreased cobalt content in roots of both plants, and manure in roots of spring barley. The effect on cobalt translocation was less clear, but most substances used in phytostabilization increased the transfer of cobalt from the soil to plants. White mustard had higher ability to accumulate cobalt than spring barley.

The Individual

Most phytoremediation technologies are based on the use of selected plant species cropped as in monoculture. Separated (monoculture) and combined (simultaneous) cropping of hyperaccumulator <i>Thlaspi caerulescens</i> and accumulator tree <i>Salix dasyclados</i> were tested in our experiment. We used moderately and highly contaminated soil. Extremely contaminated soil caused progressive mortality of willows planted separately. Combined cropping with <i>T. caerulescens</i> enabled willows to survive. Generally, we determined decreased bioaccumulation of As, Cd, and Pb in both tested species and Zn in willow plants. Combined cropping enhanced bioaccumulation of Zn in <i>T. caerulescens</i> shoots. The remediation efficiency of the individual species in the co-cropping system did not differ from those obtained in separate cropping mode. For As and Pb the negligible effectiveness of phytoextraction was confirmed for both separate and combined cropping of the tested plant species.

The effect of diatomite and tripoli added into the soil artificially contaminated with benzo[a]pyrene was studied. A decrease in the toxic effect of BaP on barley plants was established when diatomite and tripoli were added as ameliorants to contaminated soil. The improvement of plants grown сharacteristics on soils contaminated with BaP with the addition of diatomite and tripoli was shown up to 2-4 times compare to contaminated samples.

The effect of applying various norms of mineral fertilizers on the biological indicators of crop plants during their growth and development in the Central non-black earth region in 2017-2019 was studied on the varieties of spring barley Vladimir, Reliable and Yaromir.such indicators as plant height, photosynthetic apparatus area, green mass growth, and elements of the yield structure were Studied. It was revealed that on average during the growing season, when the norms of mineral fertilizers were increased, the area of leaf plates increased and, as a result, the increase in green mass growth relative to the control variants increased by 56.3 % at (NРК)30, 82.3 % at (NРК)60, and 126.7 % at (NРК)90. The introduction of mineral fertilizers also influenced the formation of the crop structure. There was an increase in the tillering coefficient of varieties by 15.7%, 5.7 % and 21.3 % (Vladimir, Reliable and Yaromir, respectively) relative to the control, an increase in the number of grains in the ear from 15.1 to 22.4 PCs., the weight of 1000 grains from 48.0 to 55.7 g. and the weight of grain per ear from 0.7 to 1.2 g. There was a strong correlation between the doses of mineral fertilizers and the grain yield from + 0.80 to +1.0, and the variability was calculated.

ABSTRACT Soil pH is a major factor shaping bulk soil microbial communities. However, it is unclear whether the belowground microbial habitats shaped by plants (e.g. rhizosphere and root endosphere) are also affected by soil pH. We investigated this question by comparing the microbial communities associated with plants growing in neutral and strongly alkaline soils in the Sandhills, which is the largest sand dune complex in the northern hemisphere. Bulk soil, rhizosphere and root endosphere DNA were extracted from multiple plant species and analyzed using 16S rRNA amplicon sequencing. Results showed that rhizosphere, root endosphere and bulk soil microbiomes were different in the contrasting soil pH ranges. The strongest impact of plant species on the belowground microbiomes was in alkaline soils, suggesting a greater selective effect under alkali stress. Evaluation of soil chemical components showed that in addition to soil pH, cation exchange capacity also had a strong impact on shaping bulk soil microbial communities. This study extends our knowledge regarding the importance of pH to microbial ecology showing that root endosphere and rhizosphere microbial communities were also influenced by this soil component, and highlights the important role that plants play particularly in shaping the belowground microbiomes in alkaline soils.

The use of plant species to stabilize and accumulate trace elements in contaminated soils is considered of great usefulness given the difficulty of decontaminating large areas subjected to mining for long periods. In this work, the bioaccumulation of trace elements is studied by relating the concentrations in leaves and roots of three plants of Mediterranean distribution (Dittrichia viscosa, Cistus salviifolius, Euphorbia pithyusa subsp. cupanii) with the concentrations of trace elements in contaminated and uncontaminated soils. Furthermore, in the case of D. viscosa, to know the concentration of each element by biomass, the pool of trace elements was determined both in the aerial part and in the roots. The bioaccumulation factor was not high enough in any of the species studied to be considered as phytoextractors. However, species like the ones studied in this work that live on soils with a wide range of concentration of trace elements and that develop a considerable biomass could be considered for stabilization of contaminated soils. The plant species studied in this work are good candidates for gentle-remediation options in the polluted Mediterranean.
