Nanoparticles are increasingly used in many industrial fields because of their special properties. In this context, several questions arise related to possible negative consequences associated with nanoparticle (NPs) entrance into the ecosystem. The adsorption of NPs by soil can adversely influence its biological properties. In the present article, the influence of Cu, Zn, and Ni NPs on the biological characteristics of Arenosol is considered. Research aimed to study the effect of Cu, Zn, Ni NPs on the biological characteristics of sandy loam chernozem. Copper, Zn, and Ni NPs were added to the soil in concentrations of 100, 1,000, and 10,000 mg kg-1. The effect of NPs on the biological properties of Arenosol was evaluated after 10-day incubation. The biological indices of the ecological condition of the soil, including the germination of radish, the length of the roots, the bacteria population, Azotobacter sp. count, the catalase activity, and dehydrogenases were studied. As a result of this study, it was revealed that the degree of indices changes depending on the concentration of Cu, Zn, and Ni NPs in the Arenosols. Microbiological characteristics (bacteria population, and Azotobacter sp. count) and phytotoxic feature (length of roots and radish germination) properties were most sensitive to contamination compared to the enzyme activity of Arenosol. Based on the soil integral index of a biological state, the strongest inhibitory effect on biological parameters of Arenosols relative to the control was exerted by Cu NPs (lower than control by 48-72%), while the greatest stability in Arenosol was found for Ni NPs (lower than control by 30-55%). The studied biological parameters allow characterizing the severity of nanoparticle exposure on Arenosols. Early diagnostics of the severity of soil contamination by NPs can be successfully used to quickly assess their impact on the soil condition and prevent possible adverse consequences.

“…Various containers for cultivation are being tested [4], natural and artificial substrates [5][6][7]. The influence of growth stimulators [8][9], pre-sowing preparation of seeds [10][11][12] fertilizers at different stages of seedling development [13][14][15] and the importance of irrigation [16] are studied. To increase stress resistance, seedlings are grown with the addition of spores and cultures of ectomycorrhizal fungi to the substrate [17][18].…”

The article presents the results of research on growing seedlings of Pinus sylvestris L. with a closed root system in a greenhouse when sowing in cassettes, on three types of substrates and 7 variants of presowing treatment with various growth stimulants, which affected the energy of seed germination and germination, and also on increasing the total number of germinated seeds during the first month. Good germination results were obtained when seeds were treated with Borogum-M, Bogatyi-Micro, Bionex-Kemi preparations in low-density peat, filled with the starting composition of fertilizers. But in the subsequent period, the development of seedlings was more intense on denser peat with the addition of humic acids and salts, mineral fertilizers, trace elements, strains of soil microflora and mycorrhiza. Biometric indicators of seedlings also turned out to be slightly higher on this substrate. It is proposed to grow pine seedlings during one growing season on low-density peat with the addition of a complex of components.

This paper shows the effect of iron nanopowder on productivity and physiological and biochemical processes, the metal is used at an optimal concentration of 1 g per hectare (seeding rate) of winter wheat variety Moskovskaya 56. Iron nanopowder is quite effective in dressing winter wheat before sowing. At the same time, it increases the length of the roots of experimental winter wheat plants by 22.8%, and also increases the dry weight of plants by 8.9%, which is associated with its biocatalytic properties. The effect of iron nanoparticles on the accumulation of water-soluble polysaccharides in winter wheat plants during the tillering period before the winter period was studied. Iron nanopowder increases the accumulation of polysaccharides in the whole plant by 4.2%, in the tillering node by 4.6%, in the roots - by 0.7%, these changes increase the winter hardiness of winter wheat. It is shown that iron nanopowder increases the yield of winter wheat grains by 19.7%, the weight of a thousand grains by 7.5%, the number of spikelets in an ear also increased by 13.3% and the number of grains in a spikelet - by 14.5% higher than control . Under the influence of the optimal concentration of iron nanopowder, the chemical composition of wheat grain changes, the content of gluten in the grain increases by 2.0% and its quality index, and the ash content of grain also slightly increased (+0.2% higher than the control). Based on the results of the research, it is possible to recommend the introduction of iron nanopowder into the production of winter wheat.
