Published: June 2022

Abstract
The article describes the operating conditions of a rotary blanching machine with synchronization of the angular velocity of the rotor with its metering device. Analytical equations describing the motion of a material particle during the transition from a paddle dispenser to a cassette container are derived. The basic requirement for the blanching machine design is justified, which consists in the fact that by the time the material weight detached from the dispenser blade to the cassette arrives, the lid of the latter must be fully open. This happens in the I-th, then in the II-th quadrant it closes and in the IV-th quadrant it opens.

Authors: Tubalov A A , Kholodenko A V 
Published: June 2022

Abstract
The present research is aimed at studying the impact of the modern no-till agricultural technology on the development of erosion processes on cultivated arable land in the subzone of the southern chernozems of the Volgograd region. Evaluation of the impact of this agricultural technology was based on the analysis and comparison of soil cover in hollows located in the fields cultivated using either the classic technology or the no-till technology. The research methodology is based on combination of remote, field and laboratory methods for studying the soil cover. Analysis and generalization of data obtained in the course of laboratory studies of selected soil samples made it possible to identify a high degree of erosion processes in the hollows located in the fields, which had been cultivated using the no-till technology for three years. Comparison of the values of the content of organic carbon in the zones of removal, transit and accumulation of fine earth indicates the development of water degradation processes in the middle part of the hollows. Thus, for soil samples taken from a depth of 0-10 cm, the value of organic carbon content in the variant of soil tilled using the new technology is 2.6%, while in the variant tilled using the classic technology, this value is equal to 3.1%. The revealed differences in the soil cover of the hollows can be explained by interaction of the patterns of development of erosion-accumulation processes and the features of the no-till technology in specific natural and climatic conditions.

Authors: Buldakov S A , Shakleina N A , Plekhanova L P 
Published: June 2022

Abstract
The article presents long-term studies on the study of agrotechnical and chemical measures to combat potato late blight in the Sakhalin region. At the initial stage of work (1951-1966), the local population of the fungus Phytophtora infestans was studied, and a method for short-term prognosis of the disease was developed. For the first time, a complex of agrotechnical and chemical measures was developed: preplant germination and treatment of tubers with microelements (Cu, B, Mn); joint application of fertilizers and copper sulfate; double spraying of potato seedlings with microelements; fungicide treatments; removal of tops on seed plots before harvesting; post-harvest planting of seed material. Between 1996 and 2019 the improvement of disease control measures was carried out on the basis of the use of chemical and biological agents. In 1996-2003 among the studied modern fungicides, the most effective were systemic preparations (Acrobat MC, Ordan), as well as the combined use of Ordan with the biological product Planriz and Sodium Humate, which made it possible to reduce the development of the disease by 24.2-69.1% and increase the yield by 17.3-48.9%. According to the results of research in 2016-2019. Innovative combined action fungicides Infinito and Consento had the maximum protective effect against fungal infection. The use of drugs under production conditions made it possible to reduce the degree of damage to the vegetative mass by the pathogen by 56.5-60.0%, and increase the yield by 31.2-36.5%. Technical efficiency corresponded to 67-71%. The studied biopreparations (Trichocin, Vitaplan) are recommended for prophylactic treatment of potatoes in the initial period of vegetation.

Authors: Eshbayev O A , Mirzaliev S M , Rozikov R U , Kuzikulova D M , Shakirova G A 
Published: June 2022

Abstract
Nowadays, environmental preservation is becoming the arena where technological breakthroughs and advances are implemented as the promising way for the future sustainable development of humanity. To provide quality environmental designs and effective environmental policies as their basic functions respectively, environmental engineering and management programs are also faced with acknowledgment of modern technologies in the division of their environmental affairs. This paper proposes an approach that is based on two specific directions of information technologies (natural language processing (NLP) and machine learning (ML)) to increase the efficiency of environmental management policies and engineering practices. Those two fields of informatics are critical points in developing environmental awareness or competencies of environmental managers/engineers since there are many existing occlusions to be removed in developmental path of environmental management/engineering such as less accurate performance of systems, environmentally-savvy technologies for reforms, and so on. Literature review and stakeholder analysis methods are used in reviewing management operations and engineering practices to determine how two directions of computer science help increase the efficiency of those ecological majors and propose research informed guidelines. The results show that machine learning, and natural language processing are keys to performing “minimize risk” job assignments such as predicting and awareness.
Patterns of differentiation of the old arable horizon of fallow soils according to the content of mobile forms of manganese and copper
Authors: Giniyatullin К G , Okunev R V , Smirnova E V , Sahabiev I A , Latipova L I 
Published: June 2022

Abstract
The differentiation of the old arable horizon (Ap old) by the content of mobile manganese (Mn) and copper (Cu) under fallow vegetation aged 15-20 years was studied. The accumulation of mobile Mn in the upper layer (0-10 cm), Cu in the 5-15 cm layer was observed. Linear modeling of the dependence of the content of Mn and Cu on alkali-soluble organic matter (OMP) and pH showed the influence of only one significant predictor on each element. The content of Mn has a significant strong (R2
adj.=0.72) influence of OMP. The pH has a statistically significant, but weak (R2
adj.= 0.19) effect on the Cu content. The difference in the patterns of differentiation is associated with the accumulation of mobile Mn by newly formed organic matter (OM) in fallows and the migration of mobile Cu with soluble fractions of OM in acidic soils. The study of changes in the mobility of heavy metals (HMs) in fallows is necessary to reduce environmental risks when changing land use, as well as to provide a realistic prediction of atmospheric carbon sequestration in fallow soils, taking into account changes in the level of toxicity of HMs. The relevance of these studies is associated with the fact that the removal of lands with heavy HM contamination from arable circulation in fallows is practiced more and more often.

Published: June 2022

Abstract
The article analyzes and presents data on the growth and development of the Phoenix fiber flax variety during the growing season, depending on the type and ratio of mineral fertilizers. The object of research was the variety of fiber flax Phoenix. The use of the tested types of mineral fertilizers made it possible to obtain a yield of flax straw up to 9.49 t/ha and seeds up to 0.34 t/ha. In general, the most effective was the use of fertilizers in option 11 (pre-sowing application of NPK(S) 8:20:30(2) + 0.3B at a dose of 200 kg/ha + Ammophos NP 12:52 at a dose of 133 kg/ha + Kalimag 38 at a dose of 137 kg/ha + top dressing in the herringbone phase ammonium nitrate 34.6 at a dose of 59 kg/ha + trace elements), where the level of yield relative to the control increased by an average of 100% for straw and 70% for seeds. All yield data are confirmed by the elements of its structure. Thus, plant height ranged from 68 to 91 cm, technical length - from 54 to 70 cm, number of plants before harvesting - 1232-1616 pcs/ha, seed weight per plant - 0.16-0.22 g, straw weight - 0.40-0.60 g.

Authors: Vaitekhovich Iurii , Lyude Anna , Boiarskaia Anastasiia , Hasegawa Hideo 
Published: June 2022

Abstract
Soybean as a valuable fodder and oilseed crop has taken the primary place in agriculture of the Amur region, occupying 75.4% of the total sown area in 2021. However, research and experimental data on the vegetable alternative of soybean for the region are insignificant. This study suggests that given complex economic, cultural, and climatic conditions changes, successful introduction and cultivation of vegetable soybean Edamame is timely and needs investigation. The climatic conditions analysis demonstrated that the mean annual temperatures increased in the observed period (1910-2021). Analysis of the similarities and differences in grain and vegetable soybean cultivation, including necessary agricultural machinery, suggested that partial re-equipment of the technical base for harvesting and postharvest processing of vegetable soybean could make it fully possible to cultivate Edamame. Given the high vulnerability of vegetable soybean to excess moisture and a tendency of the Amur region loamy soils to waterlogging, drainage amelioration measures were recommended. It is concluded that for the efficient cultivation of Edamame, further substantial research and longitudinal field studies of profitability, region-specific agrotechnology, and appropriate soybean varieties are necessary.
Diversity of ectomycorrhizal structures of Larix sukaczewii and Pinus sylvestris
Authors: Mukhametova G M , Zaitsev G A 
Published: June 2022

Abstract
The ecological value of ectomycorrhizal associations is not restricted to the organism level. They play an essential role in plant communities as key to the diversity and sustainability of species. The sustainability of forest stands in urbanised areas depends on preserving mycorrhizal communities’ structural and functional organisation. Reducing species diversity of ectomycorrhizal associations does not lessen the resilience of forest ecosystems in industrial centres but is balanced by morphological diversity.

Published: June 2022

Abstract
The article presents the results of an immunological assessment of the North Caucasian (NC) and Belarusian (BL) populations of pink snow mold (pathogen Microdochium nivale (Fr.) Samuels & I.C. Hallett) of 2 triticale varieties, 3 rye varieties, 2 winter barley varieties of Belarusian selection and 11 varieties barley, 20 varieties of winter wheat of Russian selection in the seedling phase. Infectious material was selected from two geographically distant zones - the population of the fungus of the North Caucasus region of the Russian Federation (NC) and the population selected on the crops of the Republic of Belarus (BL). It was revealed that resistance to NC was shown by one variety of winter triticale Grenado with a degree of damage of 3.2 points. Winter rye varieties showed different degrees of susceptibility to both populations: Zazerskaya 3 (NC - 5.0 points, BL 8.2 - points), Forzetti (NC5.2 - points, BL 6.4 - points), Golubka (NC - 5.4 points, BL 7.2 points). High resistance to both pathogen populations was found in the winter barley variety Vivat (NC - 2.8 points, BL - 2.6 points). High resistance relative to both populations was found in winter wheat varieties: Helios (NC - 2.0 points, BL - 2.4 points), Iliad (NC - 2.0 points, BL - 2.8 points) and Soberbash (NC 2, 8 - points, BL 2.8 - points). The degree of plant damage by the Belarusian population of the pathogen of pink snow mold was higher than the North Caucasian population (Ft4.0<Ff4.5) with a moderate degree of correlation of damage by different populations (rxy=0.33), which indicates a higher aggressiveness of the pathogen common on crops grain crops of Belarus.

Authors: Tishkina E A 
Published: June 2022

AbstractThe article studies the adaptive mechanism of the distribution ofAcer negundoL. on the example of habitats in the Southwestern forest park based on population (age and vitality structure) and organismal parameters (morphometric indicators). An assessment of the invasive potential made it possible to establish similar features of the introduction of the ash-leaved maple in any of its habitats. All fragments of the cenopopulation were at the initial stage of introduction and began their expansion from open spaces, well settling in forest ecosystems, mainly in forb and horsetail-forb pine forests with a tree canopy density of 0.4–0.5. This trend of conquest of the territory by the “aggressor” species continues at the present time, and it can be said with confidence that this situation is typical for many regions of Russia, therefore, it is necessary to monitor the state of ecosystems.

Use of digital characteristics of soil color for assessing the degree of soil erosion
Authors: Tubalov A A 
Published: June 2022

Abstract
The present study is aimed at developing and improving approaches to assessment of the degree of soil erosion. The transition from verbal to digital form of determining the color of soils expands the possibilities of using this morphological feature. It allows determining the thickness of soil horizons based on the data of laboratory analysis of the color of soil samples. The methodological basis of the study is represented with the index method or the method of field standardization of territories. According to this method, the main contour of the soil is characterized by a full-profile soil pit, and soil changes caused by the relief near the main pit are estimated by changes in the characteristics of soil layers. Measurement of the latter was carried out in the course of the laboratory analysis of soil samples selected by soil drilling. As a result of the study, the soil color coordinates were determined in the CAI Lab system. Their values correspond to the soil samples of the southern chernozem taken at a depth of 1 meter every 10 centimeters. The linear nature of interconnection between the index of organic carbon content in the soil samples and the corresponding values of the lightness index in the CAI Lab color model was confirmed. The soil samples with varying degrees of erosion were identified in a research object: soils of watersheds unaffected by erosion processes; moderately eroded soils of hollows exposed to water erosion; drift soils of the mouth of hollows.

Comparison of organic-inorganic p-i-n and p-n heterostructures as potential solar cell designs for use in difficult weather conditions
Authors: Yu Strekert O , Marsov N G 
Published: June 2022

Abstract
This paper investigates the possibility of increasing the spectral sensitivity of an organic-inorganic p-i-n-heterostructure solar cell as compared to a p-n-structure solar cell. Both p-i-n and p-n structures are fabricated from gallium arsenide (GaAs) and copper phthalocyanine (CuPc) using the same technology. In fabricating the p-n-structure, CuPc is deposited in a thinner layer and is fully doped with oxygen; in fabricating the p-i-n-structure, CuPc is deposited in a thicker layer and only its upper part is doped. The main properties of both heterostructures are investigated. The shift in spectral absorption maximum towards the shorter wavelength portion of the spectrum is found to increase the spectral sensitivity and efficiency of the p-i-n-heterostructure n-GaAs/(i-CuPc)/p-CuPc compared to the p-n-heterostructure n-GaAs/p-CuPc. The discussed technology can be used to optimize the solar cell performance under the low temperature and cloud cover conditions.

Abstract
One of the most important factors for maintaining human health is a good nutrition of macro and micronutrients. Insufficient nutrition of essential nutrients leads to various disorders of the body. In recent years, more and more malnutrition has been observed, especially a deficiency of polyunsaturated fatty acids, vitamins and minerals. Of great interest is pumpkin seed oil, which is rich in linoleic acid. Linoleic acid belongs to the polyunsaturated fatty acids of the omega-6 family, which is not formed in the body and must be constantly supplied with food. Cultivation of pumpkin in the temperate zone is very important. This will provide the population with vegetable oil with high biological efficiency due to the content of linoleic acid. The fatty acid composition of pumpkin seeds is influenced by many factors: climatic data, varieties, agricultural practices, etc. Mechanized industrial crops of pumpkin are located mainly in the southern regions, due to the fact that this crop is thermophilic. In recent years, there has been a change in climate, in the temperate zone, the growing season has increased due to the earlier onset of spring and later autumn, the sum of active temperatures, etc. There is a certain tendency to increase the area occupied by this crop in the temperate zone. The correct selection of varieties and variety samples for mechanized cultivation becomes an urgent task. The experiments were carried out in the Moscow region. 16 varieties and variety samples were studied according to the standard method. A high oil content in the studied samples was revealed - The studied varieties and variety samples have a high oil content: from 33.6 to 54.6%. When studying the fatty acid composition, the highest content is represented by the essential polyunsaturated fatty linoleic acid up to 68.55% - in the Pivdenny variety.
