Abstract
This study has a great practical and economic significance for regions with oil- contaminated soil. The concentration of oil products in the studied soil samples was determined by four methods: extraction from soil samples with n-hexane using a fluorescent photometric analyzer «Fluorat 02-3M LUMEX», carbon tetrachloride using an analyzer «AN-2», and chloroform using a gravimetric method. The data obtained make it possible to estimate the effectiveness of the application of the methods of analysis. There are also identified the advantages and disadvantages of direct and indirect methods for determining soil organic carbon, the effect of oil pollution on soil pH and carbon content in the soil. Evaluation criteria are proposed to improve the objective assessment of the state of oil-contaminated soils.

Abstract
Modern agriculture is waiting for selection to create varieties, forming high, stable and high-quality grain crops in different conditions of cultivation. Although, recognized varieties of winter wheat don’t always ensure getting high and good quality grain crops. Resolution of this problem is seen in more profound study of photosynthetic activity of plants and and using its indices in selection. During the years of research the interval of genotypic variation in crop power of culture grain was somewhere in between 2.6…5.5 t/ha. Content of protein and fibrin in the studied breeds was varying average from 13.5 to 16.0 % and from 21.1 to 28.5 %, respectively. Between indices of crop power and content of protein the correlation parameter was changing from -0.27 to +0.16, but with fibrin in content – from -0.16 to +0.18. Connection of photosynthesis and transpiration activity with grain quality was more considerable. Correlation coefficient between photosynthetic rate of leaves and content of protein and fibrin was positive and equal to 0.62 and 0.47 respectively, but between transpiration rate and content of protein and fibrin amounted to -0.34 and -0.15, respectively. It’s established that the higher the correlation of photosynthetic rate with transpiration activity of leaves among varieties of culture, the better the quality of developing grain crops. Evaluating the genotypes of winter wheat taking into consideration the effectiveness of using water allowed establishing a broad range of indices variation – from 1.88 to 4.19. Varieties with high value of this index (from 3.41 to 4.19 CO2/H2O) were characterized by increased content of both protein and fibrin: Moskovskaya 39 - 14.5 % and 24.1 %, respectively, Moskovskaya 40 - 15.0 % and 24.8 %, respectively.

Abstract
Arid lands are areas with arid climate and lack of water resources necessary for productive activities within the agro-industrial complex (AIC). The factor of aridity of lands is one of the key negative factors for economically effective crop production and development of fodder base in the structure of animal husbandry. The main characteristic of these lands is the insufficient level of irrigation and moisture supply due to the lack of internal water and precipitation. In this connection for successful development of agroindustrial complex by means of application of mentioned territories it is necessary to search and identify complex measures and ways directed on preservation of natural-productive qualities at the expense of optimal combination of ecological and economic components in organization of regulation of moisture and water supply system. The specified development of a balanced set of measures of economic and ecological nature is aimed at preventing further increase in the level of aridity and desertification of agricultural lands.

Abstract
Increasing grain production and improving its quality are of great importance for our country. A special role is given to winter wheat as a highly productive and valuable food crop, which occupies about 2 million hectares in the Central Black Earth Region. Winter wheat also occupies significant areas in Belgorod region, which, according to agroclimatic zoning, is included in the zone of unstable moisture. Under these conditions, the development and opening up resource-saving adaptive technologies for the cultivation of crops, in particular winter wheat, as the most important grain crop, which would be assessed not only by productivity, but also by the degree of anthropogenic load on ecological systems, are of particular importance. The aim of the research is to change the agrophysical and biological properties of the soil, weed infestation of crops, yield and quality of different varieties of winter wheat, depending on preceding crops, new types of fertilizers and growth regulator. In this work, for the first time for the Central Black Earth Region, the complex effect of preceding crops, new types of fertilizers and growth regulator on changes in agrophysical, biological properties of soil, yield and quality of cultivated varieties of winter wheat Maiskaya Yubileinaya and Almera was studied. A complex of agrotechnical techniques for different varieties of winter wheat, identified on the basis of the research results, based on the use of optimal preceding crops, new types of fertilizers and plant growth regulators, allows the development of energy and resource-saving technologies of the cultivated crop. The expediency of using the most adaptive for the conditions of the region combination of agricultural practices for promising varieties of winter wheat is shown.

Abstract
Currently, medicinal plant growing is one of the promising areas of activity of agricultural enterprises in the Russian Federation. This area has a high economic potential. The deterioration of the general ecological situation, the instability of weather conditions have a negative impact on the growth and development of medicinal crops, leading to a decrease in plant resistance to stress factors and the inability to fully realize their potential with cultivated varieties. Plant growth regulators are one of the most promising groups of pesticides, the advantages of which are that they are harmless, environmentally friendly and highly effective at low consumption rates of biologically active substances of polyfunctional action. Exogenous use of growth regulators makes it possible to activate physiological and biochemical processes, regulate individual stages of morphogenesis, in order to mobilize the potential of the plant organism, aimed at overcoming unfavorable environmental conditions by plants, increasing their resistance to harmful organisms and ensuring optimal productivity. On the territory of the collection nursery of the Middle Volga branch of the FSBI VILAR in 2018-2020, an experiment was carried out in order to study the effect of growth regulators and micronutrient fertilizers Zircon, Epin-extra, Ferovit and Siliplant, on the resistance of plants to unfavorable growing conditions, increasing the yield of inflorescences and seeds of calendula officinalis. Ferovit turned out to be the best result of application in the raw material areas for three years of research in the prevailing weather conditions. The average yield of raw materials of air-dried inflorescences was 2.10 t / ha, which is 0.45 t / ha more than the control variant. On seed plots, the best indicators were obtained with the use of Siliplant micronutrient fertilizer 1.25 t / ha, which is 0.2 t / ha more than the option without the use of drugs.

Abstract
The process of bioconversion of the secondary product of pea flour processing into protein concentrate (serum) into fodder microbial-plant concentrate has been optimized. For this, a composition was selected from the culture of the fungus Geotrichium candidum 977 and the yeast Saccharamyces cerevisiae 121, a mathematical model of concentrate synthesis was developed in the form of an equation that adequately describes the dependence of the biomass yield on technological parameters: pH of the medium, temperature and amount of inoculum. The concentrate from the biomass had a protein mass fraction of 61.68 % of DS, from the biomass with the culture liquid - 57.90 %. Concentrates - biologically complete, the rate of essential amino acids was 107-226 %, out of 30 fatty acids, 97 % were acids that are part of animal fats, vegetable oils or marine organisms. The ratio of saturated and unsaturated acids is 1:3, the content of trans isomers is 5.1 %, omega-6 fatty acids (linoleic) is 19.73 %. The ability of symbiosis between the yeast S. cerevisiae 84/5 and the fungus Trich. cutaneum 656 has been proven. transform the components of whey remaining after the extraction of phytin from rice bran into protein biomass. The ratio of monocultures by mass fraction is 1:1, pH - 5.0…6.0, duration of growth - 72 hours, digestibility – 90 %. The protein is enriched with methionine, isoleucine, leucine, lysine. The amount of essential acids is 18-21 % higher than in concentrates obtained from individual monocultures. The use of concentrates is advisable to use in the diet of animals.

Published: September 2021

Abstract
The composition and diversity of microbial communities from the cold ultra-fresh oligotrophic seeps and River Sukhoe Ubzhogoe of the National Park "Alkhanai" were determined via culture-dependent vs. culture-independent approaches. The microbial community of six groundwater seeps determined by 16S rDNA cloning, and sequencing consisted of four dominant genera belonging to the classes Betaproteobacteria and Gammaproteobacteria; they were Duganella sp., Janthinobacterium sp., and Pseudomonas sp., Serratia sp., respectively. Uncultured bacteria were presented by the phylum Bacteroidetes, classes Flavobacteriia (Flavobacterium sp.), Cytophagia (Flexibacter sp.), and Chitinophagia (Sediminibacterium sp.); the phylum Proteobacteria, classes Betaproteobacteria (Comamonadaceae) and Gammaproteobacteria (Acinetobacter sp.); and the phylum Actinobacteria, class Actinomycetia (Rhodococcus sp.). The same chemoorganoheterotrophic bacteria were cultivated as dominant species from the waters of the investigated seeps. Still, differences in the microbial communities were found in a proper combination of the four dominant forms of bacteria in the appropriate ecosystems. One of the peculiarities of the cultivable bacteria was the production of colored pigments violacein and prodigiosin, known for their therapeutic properties. The subject is promising for fundamental and applied research. Curative properties of cold seeps were discussed, and it was proposed that the water quality could assume medicinal qualities due to the specific composition of microorganisms.

Published: September 2021

Abstract
The article presents the results of the analysis of amino acid composition of grain of spring soft and durum wheat varieties by the amount of proline and essential amino acids under conditions of favorable and dry years in terms of weather factors. An increase in the amount of proline was established under conditions of temperature stress and a lack of moisture in soil, it allows us to consider this fact as an index of resistance to unfavorable environmental factors. The amount of essential amino acids depended on weather and technological factors. The content of the amino acid proline in spring wheat grain should be considered as a signaling function for stressful vegetation conditions. The content of essential amino acids in spring wheat grain increases in favorable years and against the background of moldboard plowing.

Published: September 2021

Abstract
This study evaluated the effects of oil pollution, low humidity, and plant co-cultivation in kastanozem on Sorghum bicolor L. Moench and Medicago falcata L. Under the influence of oil pollution, the accumulation of sorghum biomass and the content of its photosynthetic pigments decreased. At the same time, an increase in the concentration of protein in the roots of this plant was not accompanied by an increase in the peroxidase activity. The reduced humidity did not have a negative impact on sorghum. The pollution also reduced the yellow medick biomass and the content of its photosynthetic pigments and proteins in leaves. At the same time, an increase in the protein content in the roots was accompanied by an increase in the peroxidase activity. The low humidity promoted an increase in the concentration of protein in the leaves and an increase in the peroxidase activity in the roots. The plant co-cultivation reflected positively on the sorghum state and negatively on the alfalfa state. The data obtained can be used by phytoremediation technology for kastanozem cleaning up from oil hydrocarbons and rehabilitation of soil biological activities in arid regions.

Published: September 2021

AbstractThe main purpose of the article was to update the fundamental component in the creation of phytocenoses with controlled properties in the feasibility of ensuring the stability of the structure, composition and condition of such communities. This direction plays an important role in ecological and economic activity, in modern nature management. The key aspects of the management of artificial phytocenoses which form the functional core of cultural ecosystems and landscapes are presented. Crop production, as well as botany and plant ecology as its overall fundamental basis, should implement the goals of strategic and territorial planning in this key. Designing and monitoring the efficiency of phytocenoses of the corresponding economic groups allows ensuring the productivity and sustainability of ecosystems and landscapes. In this case biology, ecology and geography of plants make it possible to determine the fundamental mechanisms of management of artificial biosystems in the corresponding territories. Ensuring a labile balance between potential and real opportunities in biological productivity and environmental sustainability of artificial plant communities is the scientific basis of ecological and economic activity. Phytocenoses of landscaping purposes have significant scientific and practical interest: decorative, protective, environmental, planning. Due to the fact that the phytocenoses of landscaping structures are initially mainly artificial biotic formations, the ecological, landscape-stabilizing and economic characteristics of the ecosystems of cities and villages, first of all, depend on the species and varietal composition of the plants used. Also, these biotic communities strongly depend on the possibility of realizing the biological potential of these plants in such non-specific environmental conditions.

Authors: Bayanova A A 
Published: September 2021

Abstract
Despite the fact that substantial water resources are concentrated in the Irkutsk region, the research revealed the problems of providing the population with high-quality drinking water from centralized water supply systems. Monitoring the quality of drinking water from centralized water supply showed the presence of sources that do not meet sanitary and epidemiological requirements, which is associated in the overwhelming majority of cases with the absence of sanitary protection zones. The discrepancy with the adopted regulations of a part of sanitary-chemical and microbiological samples of drinking water was revealed. Deviations are mainly caused by an excess of the content of iron, aluminum, manganese, nitrates, magnesium, as well as general and thermotolerant coliform bacteria. The reasons for the unsatisfactory state of drinking water are detected and measures are recommended to ensure the appropriate quality for the sustainable development of the area under research.
