Published: October 2021

Abstract
The studies were carried out in the conditions of the Krasnoyarsk forest-steppe on the basis of the Krasnoyarsk Research Institute of Agriculture. The weather conditions of the years of the study differed from each other: 2018 - very dry Hydrothermic Coefficient (HC) 0.60; 2019 - arid HC 0.89; 2020 - moderately humidified HC 1.32. The soil of the plot is ordinary heavy loamy chernozem with an acidity of the soil solution of 6.8 and humus content of 7.8 (according to Tyurin). The researches were carried out in accordance with the guidelines for the study of the collection of the world’s genetic resources of cereal legumes. For the study, 9 samples of peas of different morphotypes were taken. The proportions of the influence of genotype and year conditions on the characteristics of the productivity of the samples were determined - the number of unproductive and productive joints, the number of beans and seeds per plant, and the length of plants. The climatic conditions of the year of cultivation had the greatest influence on the main characteristics of productivity, such as the number of beans per plant, the number of seeds per plant, and the number of productive joints. In terms of the number of beans and seeds per plant, 75% was attributed to the influence of the conditions of the year and 45% to the influence of the variety and the interaction of factors, variety x year. The length of the plants was significantly influenced by the year of cultivation - 66%, the influence of the genotype was estimated at 24%, the interaction of factors at 10%. The factor of the year had a minimal effect on the number of unproductive joints - 19%, the influence of the variety was 80%.

Abstract
The study of the genetic characteristics of the reaction of plants to changes in environmental conditions makes it possible to more effectively use the achievements of breeding. In the conditions of the open forest-steppe of the Krasnoyarsk Territory in 2019 - 2020, a study of the yield of winter rye was carried out on a site with a low nitrogen content against two backgrounds: without fertilizers (control) and with fertilization. The object of the research is the varieties included in the State Register for the East Siberian region Yeniseyka (standard), Sinilga, Krasnoyarskaya universal and the Arga variety undergoing state testing. In the dry 2019 year, the average yield in the control variant was 27.5 c(centner) / ha, the increase from fertilization was 8.2 c / ha. In conditions of excessive moisture in 2020, it was respectively - 32.7 c / ha and 13.6 c / ha. The response of varieties to background changes of mineral nutrition was different. The most responsive to fertilization was the Arga variety, the most stable was the Sinilga variety. Krasnoyarskaya universal and Arga surpassed Yeniseyka and Sinilga in average yield by 2.3-2.7 centners / ha and were more resistant to lodging. Arga had an advantage in productivity with a sufficient supply of nutrients, the Krasnoyarsk universal was characterized by greater stability and less response to agrotechnical background changes.

Published: October 2021

Abstract
The results of the research aimed at developing a technological platform for the cultivation of barley are presented. The technological platform is a pyramid of seven biogenic energy flows. At the base of the pyramid there are streams with sustainable natural potential. They include the conditions of the territory (climate, weather and soil with its natural level of fertility). They mainly determine the choice of variable flows - crop, variety and cultivation technology. The most changing factor with a wide range of changes is the cultivation technology. The technology is directly dependent on the soil, the climate, and the weather and is closely related to anthropogenic impact. The main variable fluxes of biogenic energy include the availability of available moisture, nutrients and weediness of crops. The tillage is the regulated, most costly energy flow. In the experiment, soil cultivation was carried out according to the traditional technology based on fall tillage (control) and minimal. Herbicide treatment allowed to reduce the contamination of the crop for harvesting by 60%. The harvest was formed in harsh weather conditions, grain. Wheat grains, on average, were obtained at 29.2 c / ha, barley - 22.0 - 26.5 c / ha.

Authors: Aksinenko O S , Kovaleva S V , Korshunov A V 
Published: October 2021

Abstract
Sulfur-containing products (elemental sulfur, polysulfides) used to control agricultural pests (powdery mildew, anthracnose, scab, spider mite) undergo chemical transformations under environmental conditions resulting in formation of toxic soluble and volatile sulfur compounds (hydrogen sulfide, sulfides, polysulfides). A relatively simple electrochemical method for monitoring the content of polysulfides in various objects based on cathodic stripping voltammetry (direct- and alternating-current modes) with a mercury-film electrode in an alkaline supporting electrolyte is proposed in the paper. It was shown that the value of the analytical signal depends linearly on the concentration of S2
2- and S3
2- ions in the range of 1•10−7-1•10−3 M. The method can be used to determine the total content of polysulfides in environmental objects and to calculate the average degree of polysulfidity n for Sn
2- ions.

Published: October 2021

Abstract
The largest salt lakes on the territory of Southeastern Transbaikalia and Northeastern Mongolia have been studied. It is shown that all lakes differ in hydrochemical and hydrobiological characteristics. According to the chemical composition of water, they belong to the soda type and sodium, carbonate, bicarbonate and chloride ions are predominant. Sulfates are in a subordinate meaning. The established relationship between abiotic and biotic parameters indicates the conjugation of biogeochemical processes involved in the formation of the soda type of lakes through the carbon cycle.

Published: October 2021

Abstract
The article considers experimental data on the study of humus content in typical chernozem, depending on the method of basic tillage, doses of mineral and organic fertilizers in conditions of long-term land use. It is determined that when plowing, it is better to apply manure at a dose of 16 t/ha in combination with mineral fertilizers at a dose of N84P124K124, and with minimal tillage – mineral fertilizers in a single dose. The correlation and regression analysis of the obtained results was carried out. It was found that when constructing 4-factor models, a strong correlation was established in the 0-10 cm layer (>0.7), and in the underlying layers an average correlation (0.53-0.60). These models will allow not only to control the humus content in typical chernozem, but also to make a forecast of its changes in the future.
The influence of mining wastes from the Russia’s Arctic zone on the plants development
Authors: Krasavtseva E A , Maksimova V V 
Published: October 2021

Abstract
This paper contains an integrated phytotesting-based assessment of the impact on the biota of the mining waste generated in Arctic zone of the Russian Federation (Murmansk Region, Russia). In order to collect as unbiased as possible data on plant growth and development, a number of test cultures of various classes were used, including monocotyledonous and dicotyledonous plants (Avéna satíva L., Lepidium sativum, Tríticum aestivum L., Trifolium praténse L.). Concentration tailings of apatite-nepheline, complex and loparite ores were studied using eluate and contact methods. Eluate phytotesting showed different levels of response in the test cultures when exposed to the native extracts of the concentration tailings. In the most sensitive cultures, the root length inhibition effect (of loparite ore concentration tailings) was less than 15%, which does not exceed the threshold inhibition value required for the phytotoxic effect to be established. When testing diluted extracts, manifestations of the hormetic (stimulating) effect were observed in some of the test cultures. Hazard class V was experimentally confirmed in the examined plant species. It was found that oats and wheat are more sensitive compared to watercress and clover — both when exposed to aqueous extracts and when germinating seeds in a substrate. The greatest plant inhibition effect was observed in loparite ore concentration tailings, which supports the conclusion that the likelihood of spontaneous revegetation of mining waste dumps is minimal and that comprehensive land remediation methods need to be developed. The results of contact phytotesting indicate the good prospects of tailings dump reclamation by mixing the top layer of the tailings with fertile soil in different ratios.

Published: October 2021

Abstract
In the summer of 2019, in many regions of the Russian Federation, there was a high death rate of honey bee families in apiaries after treating rapeseed and other fields with pesticides during flowering. The purpose of our research: to study the effect of neonicotinoids and glyphosate contained in pesticides and herbicides on Apis mellifera honey bees in laboratory conditions, to study the clinical picture of poisoning. As a result of the study, it was revealed that imidacloprid and thiacloprid have a fumigant effect from the treated surfaces for 7 days. In addition, the accumulation and death of bees from small doses can be observed on the 9th day and later. The effect of glyphosate-containing preparations on bees in laboratory conditions revealed 100% death of bees when consumed with feed. The death of bees after consuming sugar syrup with the drug, even from small doses, occurred after 15 minutes, and in the fumigation test, no death was found with prolonged exposure of the drug near bees.

Published: October 2021

Abstract
The work investigated the physical, mechanical and sorption properties of cellulose-containing wastes of agro-industrial production, formed as a result of manufacturing activities of one of the large agricultural enterprises in the Republic of Tatarstan. To improve the sorption properties, the wastes were chemically modified via treating them with sodium hydroxide solutions with 0.5, 1, and 3% concentrations at a temperature of (20 ± 2) ° C. Standard and operating diesel oils were used as sorbates. As a result of alkaline treatment, there is an increase in the maximum oil absorption of sorption materials in relation to engine oils, an increase in the sorption activity with respect to iodine, which characterizes the material porosity, as well as a decrease in the bulk density of the modified samples. The best physical, mechanical and sorption properties were found in cellulose-containing waste treated with a 3% sodium hydroxide solution.

Published: October 2021

Abstract
The article presents mobility coefficients of cadmium and copper, biological absorption coefficients of toxic metals by the main products of potatoes, beetroot and beans, depending on the chemicalization agents used on black soil with a typical heavy loamy granulometric composition. The introduction of lime, the combined application of lime and manure have a positive effect on reducing the coefficient of cadmium mobility. The high content of cadmium and copper in the soil does not have a negative effect on the synthesis of basic organic substances in vegetable products (starch, sugar, protein). The accumulation of nitrates in vegetable products occurs as a result of the mineral and organic fertilizers application; heavy metals do not have a significant effect on the accumulation of nitrate nitrogen during the cultivation of vegetable crops. The coefficient of biological absorption is influenced not only by lime, manure, mineral fertilizers, but also by the physiological characteristics of the crops themselves, which need toxic elements as micro and ultramicroelements for nutrition and synthesis of organic substances. The results of studies on crops of beetroot show that the application of lime, manure and the combined application of lime and manure reduce the intake of cadmium, copper, lead and zinc in root crops and tops of beetroot. A double dose of mineral fertilizers reduces the intake of copper and lead, but insignificantly, and does not have a positive effect on reducing the accumulation of cadmium and zinc. On soils contaminated with heavy metals (Cd, Cu), according to the value of biological absorption coefficient of the studied crops, heavy metals are distributed as follows: when growing potatoes - Cd> Cu; when cultivating table beet - Cu> Cd; when growing beans - Cu> Cd.

Published: October 2021

Abstract
Soil fertility is largely determined by the intensity and direction of enzymatic reactions. All biological processes associated with the transformation of substances and energy in the soil are carried out with the help of enzymes that play an important role in the mobilization of plant nutrients, and also determine the intensity and direction of the most important biochemical processes associated with the synthesis and decomposition of humus, hydrolysis of organic compounds and oxidative - the restorative regime of the soil, therefore, the enzymatic activity of the soil can be used as a diagnostic indicator of soil fertility under various types of anthropogenic load. The influence of the methods of basic soil cultivation on the enzymatic activity of ordinary chernozem in winter wheat crops during its cultivation on a pure and green manure fallow in the conditions of the Middle Volga region has been studied. According to the results of the studies, the highest catalytic activity of ordinary chernozem in winter wheat crops for the studied enzymes (urease, invertase, catalase, peroxidase and polyphenol oxidase) is confined to the 0-20 cm layer and is explained by the abundant location in it of the “living” root mass enriching the upper soil layer biologically active exudates that stimulate the development of microflora and activate enzymatic activity. Favorable conditions for the humification of plant residues and the accumulation of humus-like substances are formed when green manure fallow is included in the crop rotation and used as the main soil cultivation without loosening by 10-12 cm.

Authors: Tereshchenko T V , Tingaev A V 
Published: October 2021

Abstract
The objective of the study is to justify the influence of different proportions of sewage sludge introduction into the soil of a newly formed agricultural landscape on a recultivated landfill site taken out of operation. To achieve this goal it is necessary to monitor the dynamics of humidity in the recultivated areas during the growing season of 2020 under actual weather conditions. The areas were recultivated applying various technologies and the irrigation mode was introduced on the Area No. 2. This area is characterized by three types of soil: test - ordinary chernozem; a mixture of chernozem and sewage sludge; pure sewage sludge. Area No. 1 is pure wastewater sludge. The studies on humidity dynamics show that the humidity is changeable in different periods of the growing season, but in the areas with wastewater sediments, the field humidity is higher than in the test area. Thus, it can be concluded that the introduction of sewage sludge influences the structure of the resulting soil, which favorably impacts its water-retaining capacity.

Published: October 2021

Abstract
The paper conducts a comparative analysis of the adsorption capacity of a number of sorbents of different nature, production method and structure, used to extract chlorine-containing water pollutants. The main regularities, features and mechanism of trichlorethylene adsorption by sorbents were established to compare the adsorption characteristics. It was found that for trichlorethylene (TCE) weak sorbent, i.e., sorbate interaction can be a consequence of electrostatic repulsion of an organic substance molecule from polar groups on the carbon surface and adsorbed water molecules at the initial moment of adsorption. The main parameters of adsorption are calculated using the Dubinin - Radushkevich equation. The paper states that the adsorption capacity of adsorbents with respect to TCE decreases in the series PPS> AG-3 ≥ Purolat. It gives the substantiation of the choice of the sorbent for the extraction of trichlorethylene from aqueous solutions.
