Rumex obtusifolius is a troublesome weed widely spread in temperate grasslands and can be potentially used for detection of soils contaminated by trace elements. We asked how emergence and survival of its seedlings are affected by application of quick lime (Ca) and superphosphate (P) additives in soils contaminated by trace elements. We performed the pot seeding experiment with slightly acid Litavka soil contaminated by arsenic (As), cadmium (Cd), lead (Pb), and zinc (Zn) and alkaline Malín soil contaminated by As, Cd, and Zn. We used a control without any additives, Ca and P treatments in both soils. Higher and quicker emergence, together with substantially higher mortality of seedlings, was recorded in Litavka than in Malín. A positive effect of the Ca treatment on seedlings was recorded in Litavka, but a negative in Malín. Small seedlings with narrow and long leaves of reddish colour were recorded in Litavka in the control and in the P treatment both with high availability of Zn, Cd, and Pb. In the Ca treatment, leaves of seedlings were more elliptic and less reddish. In Malín, seedlings were green and substantially more vital in the control and in the P treatment than in Litavka. In the Ca treatment, small and unviable seedlings were recorded. Seedlings of R. obtusifolius are sensitive on high availability of Ca, Zn, Cd, and Pb in the soil.

Using a pot experiment with slightly acidic and alkaline soils anthropogenically contaminated by As, Cd, Pb, and Zn, we assessed how the establishment of Bryum argenteum and concentrations of elements (P, Ca, Mg, As, Cd, Cr, Cu, Fe, Mn, Ni, Pb, and Zn) in its biomass are affected by the pH of the substrate, mobility of trace elements, and by quick lime (CaO) and superphosphate (P) additives. Over one vegetation season, in pots naturally colonised by B. argenteum, a substantially higher cover of B. argenteum was recorded on acidic soil that was heavily contaminated with Cd, Pb, and Zn than on alkaline soil with higher As but lower Cd, Pb, and Zn mobility. In acidic soil, the establishment of B. argenteum was substantially improved by CaO additive, which reduced the mobility of Zn and Cd, and by P additive, which improved the P nutritional status and reduced the extremely high concentrations of many elements (As, Cd, Cr, Cu, Fe, Mn, Ni, Pb, and Zn) in its biomass. Although B. argenteum can be used for the monitoring of soil contamination, concentrations of trace elements in its biomass must be evaluated with caution as they can be affected by total and mobile concentrations of elements in the substrate, and by other soil chemical properties.

The aim of the research was to determine the effect of soil contamination with diesel oil (0; 5; 10 and 15 cm3 kg−1 of soil) on the content of trace elements in the aboveground parts of oat (Avena sativa L.). Stabilised sewage sludge was used to mitigate the likely negative impact of diesel oil on the plant. Growing soil contamination with diesel oil had a significant impact on the content of trace elements in the aboveground biomass of oat. In the series without sewage sludge, the contents of the analysed elements, except for chromium, zinc, copper and cobalt, were positively correlated with the increasing doses of diesel oil. The largest increase in the content was recorded in the case of manganese. The sewage sludge used to reduce the influence of diesel oil on the chemical composition of oat had a positive effect on the content of the analysed trace elements. Compared to the series without the addition of a stabilised sewage sludge, it contributed to a reduction in the average content of chromium, nickel, copper, manganese and cobalt in the aboveground parts of oat plants. No significant effect of the applied remediation treatment was noted for cadmium, and the results were equivocal for iron.

Current biomedical field demands intensive research on cost-effective and high availability materials to fulfil its various applications. Owing to its similar characteristic to human bone, biological hydroxyapatite (HAp) has been used as an alternative in bone replacement and implantation. In this study, biological HAp was extracted from bovine bones via calcination. Powders calcined at 700 °C and 900 °C showed the presence of HAp. The FESEM analysis shows that the irregular morphology emerged and the size was increasing as the calcination temperature increased. By increasing the temperature of 1100 °C, β-TCP started to develop and influenced the ratio of Ca/P. At 900 °C, the Ca/P ratio obtained was 1.70, and closest to the theoretical ratio of Ca/P. The presences of trace elements like Ca, Mg, Sr Na, K and Zn in all samples are proved via EDS analysis, and these elements help to enhance the bioactivity hence make it a good alternative in biomedical applications.

Trace elements in the body of the bird are in small quantities, but their role in productivity remains important. In order to get a quality carcass at the slaughterhouse, you need a constant supply of nutrients and, last but not least, microelements. Zinc and Manganese are essential trace elements that affect the growth and development of birds. And their deficiency in the body has a negative effect on the productivity of birds. In the diet of broilers trace elements are mainly added with a premix in the form of inorganic salts (sulfates, carbonates). However, these micronutrient compounds in the body of the bird are insufficiently absorbed, and increasing the dose of their introduction can cause toxicosis. Therefore, in order to prevent microelementosis, it is more appropriate to use organic compounds (chelates), which have a much higher level of bioavailability and less release into the environment. This review article describes the prophylactic efficacy of Zinc and Manganese chelates in micronutrient deficiencies in broiler chickens and laying hens. With a deficiency of a particular trace element develop metabolic disorders and other pathologies (perosis, etc.). Based on the presented data, it can be concluded that the use of organic forms of trace elements in poultry feeding is a better alternative to inorganic sources, as they can be used in smaller quantities. But due to their greater bioavailability, they are better absorbed, which has a positive effect on the productivity of broilers. Since knowledge about the use of chelated forms of trace elements in comparison with inorganic forms (salts, sulfates, etc.) in the diet of poultry is still poorly understood, it is necessary to further conduct research to prevent micronutrient deficiencies in these compounds.

The article presents the data of field experience which show that the increase in the yield of raw cotton when using the coordination compounds of trace elements of cobalt and copper on the optimal nutritional background –N250 P175 K125 increases by 4.5 and 5.8 quintals (q)/ha, respectively, relative to the cotton crop, grown without trace elements, and by 2.8 and 3.2 q/ha in the variants with the use of inorganic salts. Also, the results of research have established that the use of coordination compounds of trace elements has a positive effect on the course of physiological and biochemical processes and the yield of various cotton varieties. It is noted that the increase in yield obtained from the introduction of coordination compounds of trace elements, an average of three years of yield increase was from 12.4 to 17.7%, compared with the control. Coordination compounds Co-31, Co-34 and Cu-12 significantly improve the technological properties of the fiber and increase the oil content of the seeds of the nucleus. Thus, the greatest increase in cotton yield is observed in the variants with the coordination compound of cobalt -5.8 c/ha; the share of the first harvest of raw cotton in the variant is 74.6%, i.e. by 12.3% more than in the control variant, and in the variant with the coordination compound of copper is 4.3 c/ha per hectare compared to the control.

The aim of the present review is to summarize selenium’s connection to pests. Phytopharmaceuticals for pest control, which increase the pollution in the environment, are still widely used nowadays regardless of their negative characteristics. The use of trace elements, including selenium, can be an alternative method of pest control. Selenium can repel pests, reduce their growth, or cause toxic effects while having a positive effect on the growth of plants. In conclusion, accumulated selenium protects plants against aphids, weevils, cabbage loopers, cabbage root flies, beetles, caterpillars, and crickets due to both deterrence and toxicity.

Life Force LLC, RPE products were studied on irrigated dark chestnut soils of the Saratov Transvolga region.  The objects of the studies were Chantenay carrot variety and products, containing humic acids, as well as macro (nitrogen), meso (calcium, magnesium and trace elements).  The purpose of the research is to determine the most effective combinations of humic acid salts and chelated micronutrient fertilizers that provide a substantial increase in the yield of carrots. It is established that spraying carrots with a solution of Reasil® micro Hydro Mix increased the harvest of standard root crops by 1.85 т/ha for an average of three years (by 7% to the control). When using K- Humate -Na with micronutrients the yield increased by 5.51 t/ha (by 20% to the control). The maximum productivity of carrot within our experiments was obtained with the double application of Reasil®  Carb-N-Humic along with K-Humate -Na with micronutrients (35.88 t / ha). Similar results (35.69 t / ha) were obtained when Reasil Ca-Mg-B Animo was used along with K- Humate -Na with micronutrients. The growth of carrots and the formation of the crop were significantly influenced by the weather conditions of vegetation season. The studied products had a positive effect on the output of standard root crops, the content of sugars, vitamin A and nutrients. The content of nitrate nitrogen in all variants of the experiments was almost the same and about 4 times lower than the maximal permissible concentration (MPC). The removal of macronutrients from the soil with the carrot yield increased under the influence of microelement fertilizers.

Relevance. Trace elements are of great importance in plant life. Due to their catalytic action, they allow plants to more effectively use the main elements of nutrition-solar energy, water and macronutrients — nitrogen (N), phosphorus (P) and potassium (K), which in turn has a positive effect on plant productivity and crop quality. Rape is very sensitive to the lack of boron, zinc. Trace elements are currently presented in various forms, and therefore the purpose of the research was to identify the effectiveness of boronand zinc-containing trace elements in the processing of seed material.Methods. Theobjectofstudyisspringrape(Brassicanapus) variety Yubileiny.

This study aimed to determine the possibility to increase the the effect of different amendments (compost, bentonite and zeolite) on the shoot yield and the concentration of trace elements in shoots of maize (Zea mays L.) on soil contaminated with Cu. The yield of shoots and concentration of the trace elements in shoots of maize depended on Cu dose and amendment incorporation into the sandy soil. Cu-spiked soil caused an increase the yield of shoots (only to 100 mg Cu/kg of soil), in the concentration of Cu, Co, Mn, Ni and Fe in shoots of maize and, to a smaller degree, in the concentration of Zn and bioconcentration factor (BCF) of all elements except copper, compared to the control soil without Cu. Under the influence of 150 and 200 mg Cu per kg of soil, a decrease in yield of shoots of maize was observed. Compost, bentonite and zeolite increased the yield of shoots and reduced the concentration of Cu, Co, Mn, Fe and Zn in shoots of maize. Bentonite had a more positive effect than compost and zeolite on the yield of shoots and the concentration of Co, Mn and Zn in shoots of maize. The effect of these amendments on the Cu and Fe concentration in shoots of maize was reverse. A reverse effect of these amendments (especially bentonite and zeolite) on the Ni concentration in plants was observed. The amendments applied to soil, especially compost, increased the BCF of Ni and, to a small degree, BCF of Cu in shoots of maize, compared to the control series. Compost, zeolite and especially bentonite are very good amendments in the restoration of maize growth in polluted areas.
