Evolution of equine influenza virus between epizootics
Authors: Yurov K P , Alexeyenkova S V 
Published: September 2020

AbstractNew field strains of equid influenza virus isolated in different countries belong to independent branches in the Florida lineage, clade 2 – European and Asian. Asian viral isolates were akin to American evolutionary ancestors. Recently, there were local outbreaks of the disease with atypical symptoms among livestock. The initial diagnosis often meant a non-infectious problem. Throughout the year, horses of several equestrian bases periodically had a respiratory disease, which was characterized by a chronic course and low fever. A similar pathology in horses is described as such a chronic obstructive pulmonary disease. Sometimes the clinical picture comprised diarrhea and urticaria. In our research, several H3N8 equid influenza viral strains were isolated from the sick horses. Phenetic method of evolutionary relationships revealed their short tree distance to the equid influenza virus “A/eq/China/Ulumuqi/2015 (H3N8)” (nucleotide identity 98.43%) and viruses isolated from horses and camels in 2011-2013 in the southern regions of Kazakhstan and Mongolia (nucleotide identity 98.17%). The results supplement the data obtained by other authors characterizing the evolution and expansion of the H3N8 equid influenza virus in different geographical areas. This may allow improving the tools of diagnosis and prevention of infection.

Published: September 2020

Abstract
The highest intensity of decomposition of plant residues under spring barley crops was in the crop rotation with sideral steam of 88%, which was higher by 2.3% compared to pure, and for tillage by 88.3%. Soil enrichment with the enzyme urease on the Zvyagintsev scale is considered average and sufficient for the conversion of ammonium nitrogen in nitrogen exchange. High intensity of decomposition of plant residues, sufficient activity of soil urease are the indicators that characterize high soil fertility, were insufficient to obtain high yields of barley. The productivity of spring barley of the Povolzhsky 65 variety in some years reached 3.2 t / ha when tillage on a fertilized background in crop rotations with pure and sideral steam. Averaged four-year results on the yield of barley showed the highest results on tillage on a fertilized background and revealed the advantage of sideral steam. The correlation coefficients of decomposition of plant residues of soil and urease activity, as well as the yield of spring barley, showed a positive correlation for all variants of the experiment, in which an increase in one indicator is associated with an increase in the other.

Abstract
One of the most important factors affecting poultry productivity is the quality of drinking water. Modern preparations of foreign production that allow to remove biofilm from the water supply system along with all organic and inorganic pollutants are expensive, as well as, as a rule, negatively affect the body of poultry when drinking. The article considers the effect of water solutions of neutral anolyte “ANOLIT ANK SUPER”, as well as a solution of the preparation “DUTRION” on the intestinal microflora of poultry. As a result of the experiment, it was found that the use of 0.25% and 10% solutions of neutral anolyte, as well as the solution of the preparation “DUTRION” has a multidirectional effect on the level of bifidobacteria and lactobacilli in the intestine, but at the same time reduce the level of pathogenic and conditionally pathogenic microflora.
Study of features of differentiated soil treatment by machine-tractor units on agricultural landscapes of slope lands
Authors: Vasilyev S A , Lopotkin A M , Vasilyeva A V , Vasilieva E A 
Published: September 2020

Abstract
The paper considers the features of anti-erosion contour tillage on slope lands, taking into account the location of technological furrows at an angle to the horizontal of the slope. Obtaining information about the terrain model is possible in different ways, including before processing and during the processing of the soil on the slope by a machine-tractor unit. In this case, it is necessary to calculate the angle of deviation of the soil treatment direction relative to the slope when pro-cessing the correct areas with such machines on a complex slope. It has been established that when technological furrows are placed in a straight line, the erosion process develops significantly, for example, when using passive working bodies of agricultural machines (tooth harrows, coverers) on slope lands. For processing complex slope lands, we propose to use the active harrow as an anti-erosion tool in a machine-tractor unit. We have obtained a mathematical model for processing complex slope lands with an active harrow as part of a machine-tractor unit. The proposed approach can be used on slope lands with a slope of up to 15 degrees. Thus, the prerequisites for contour processing of soil on slopes by forming technological furrows with a zero slope are justified, which excludes additional agrotechnical and hydrotechnical anti-erosion and reclamation measures on slope lands with a slope of up to 15 degrees.

Authors: D’yachenko E N , Shevelev A T 
Published: September 2020

Abstract
The results of studies of the meteorological conditions, mineral and calcareous fertilizers impact on the barley Biom yield and quality in the Irkutsk region in 2018-2019 in a crop rotation: corn, barley + clover, clover, wheat are presented. The experimental plot soil is grey forest loamy. Corn was the precursor; mineral fertilizers were applied at a dose of N30P30K30. In the growing periods of 2018 and 2019, which are characterized as dry, the barley yield was 1.53-2.01 t / ha and 1.86-2.42 t / ha, respectively depending on the type of experiment. In 2019, raise from mineral fertilizers application increased by 12-22%comparing without adding lime, with the lime aftereffect - by 8-19% and were the largest when applying complex fertilizer. The lime aftereffect of the 1st year did not affect the gain in yield. The yield value depended to a greater extent on the depth of precipitation both for the entire growing season and for the seedlings-tillering period; the average correlation dependence between these indicators was established over two years, the correlation coefficient was 0.69 and 0.62, respectively. Grain nature increased by 1-2% with the use of nitrogen-potassium fertilizers, and the weight of 1000 grains - by 4% in the variants with the introduction of nitrogen-phosphorus, nitrogen-potassium, and complex fertilizers for both backgrounds. The lime aftereffect increased the weight of 1000 grains by 2-5%. An increase in the amount of protein in grain by 6-8% was facilitated by nitrogen-phosphorus and complex fertilizers.

Authors: Roshchin M N 
Published: September 2020

Abstract
The article is devoted to high-temperature tribological testing of carbon-containing materials during friction on 40X13 steel in the temperature range from +20 to +800°C in atmospheric conditions. The choice of temperature and test environment is determined by the prospects of creating spacecraft drives for operation without lubrication in extreme conditions. The researches have shown that the modified friction surface of CCCM in the environment of tellurium, selenium and polytetrafluoroethylene combined with steel 40X13 reduces the coefficient of friction. At a load of 1.0 MPa, sliding speeds of 0.05; 0.16; 0.25 m/s and a temperature range of +20°C - +600°C, the friction coefficient does not exceed the value of 0.3. At a temperature of 600°C, a load of 1.0 MPa, and a speed of 0.16 m/s, the friction coefficient of the samples treated in tellurium, selenium, and polytetrafluoroethylene environments is 1.8 and 4.8 times lower than that of CCCM, respectively.

Abstract
The research paper presents two stages of the study. At the first stage, table sketches of the growth progress of modal fir plantations for the mixed and green-moss type forests of the Kansk forest district and the mixed and fern-mossy groups of the Biryusinsk precinct of the Minino forest district were developed. At the second stage, using the conversion method, the conversion coefficients of the fractions of branches, needles and roots were calculated and the age-related dynamics of the phytomass of modal fir plantations of various typological-territorial groups, with its division into fractions, was determined, and the carbon stock was calculated. As a result of the studies, it was found that a high level of phytomass accumulation and carbon reserve are characterized by fir plantations of the fern-moss type of the forest of the Krasnoyarsk subtaiga region. The total phytomass of the trees of the age being up to 150 years was 205.7 t · m-3, and the carbon stock was 102.8 t / ha. The lowest indices for the mixed grass firs of the Kansk forest-steppe were established; according to the data obtained, the total plant phytomass was 123.9 t / ha by 160 and carbon 62 t / ha.

Published: September 2020

Abstract
For research, we used a root crop grinder with improved operational properties, which ensures the grinding of juicy vegetable raw materials (fodder, sugar and semi-sugar beets, rutabaga, turnips, carrots, potatoes) into pieces in the form of a parallelepiped of sizes corresponding to zootechnical requirements. The rationale for the action of forces on tubers in a stationary reference system in the process of cutting potatoes is given, the shape of which, with some assumption, is accepted as a ball. Based on the laws of mechanics, the authors obtained an analytical expression of the value of the optimum angle of inclination of the contradiction of the cutting apparatus of a particular chopper, depending on the size of the tuber, the height of the horizontal knife and the coefficient of friction. Given the values of these parameters, it is possible to fully carry out a theoretical and practical analysis of the limiting value of the angle of inclination of the contradiction of the cutting apparatus and its effect on the rolling of the tuber, as well as on its pinching.
Development of a methodology for assessing the parameters of the state of crops and soil environment for crops according to remote sensing of the Earth
Authors: Mikhailenko I M , Timoshin V N 
Published: September 2020

Abstract
Improving the efficiency of agriculture is impossible without the use of innovative solutions, among which it is necessary to highlight information technology and the use of the capabilities of the digital economy. To the greatest extent, these opportunities are manifested in such a new technological direction as precision farming which has received a new impetus for development in connection with the expanding use of remote sensing of the Earth. However, it should be noted that the use of remote sensing means for more than twenty years has so far had little effect on the effectiveness of precision farming technologies. This is due to the insufficient development of the scientific and methodological base for the use of remote sensing in the monitoring and control of agricultural technologies. Until now, the enormous opportunities of modern remote sensing tools are reduced to the construction and study of various types of vegetation indices, according to which it is impossible to make control decisions in precision farming systems. This problem is especially acute in control systems for the processes of applying mineral fertilizers, which are the main technological operations in crop production. Here, scientific and technological progress concerned only the mechanization of soil sampling at fixed points in the field and subsequent laboratory analysis of the samples. Each sampling point is considered representative for a field plot with an area of 5 to 15 ha. Such a technology for obtaining information is not only very laborious, but also carries big errors in the subsequent justification of fertilizer doses. The aim of this work is the further development of scientific and methodological foundations and software and hardware assessment tools according to remote sensing data of the content of the main nutrients in plants and soil.

Authors: Chernigova D R 
Published: September 2020

Abstract
For the analysis of regional differences in agricultural land use as the basis of rational and efficient production and procurement of food products of the region it is necessary to study land conditions. To do this, apply the relevant research and identification methods of spatial-temporal trends in the use of agricultural land based on consideration of various economic parameters. Features terms of territorial organization are characterized, as a rule, by their existing natural, socio-economic, historical factors, thereby forming the regional differences of agricultural land use. Analysis of the distribution of municipal areas according to the intensity of agricultural land use describes the state of agriculture in the region, reflecting the peculiarities of the conditions of its territorial organization. The intensity of land use is generally determined by parameters characterizing the quantitative and qualitative characteristics of land use. For these purposes, the following indicators were used as input data: area of agricultural land in municipal districts; acreage of agricultural crops; gross production, technical equipment, and mineral fertilizers. Thus, the paper presents comparative characteristics of land resources of the country and the region. The analysis of agricultural land intensity indicators is carried out among the main agrolandscape areas of the region. Areas with the most intensive and less intensive use of agricultural land are identified.

Simulation diagnostics of power train mechanical drives
Authors: Ovchinnikova N I , Bonnet V V , Kosareva A V 
Published: September 2020

Abstract
Mechanical drives have become the most widely used in design of agricultural machinery. In comparison to drives of machinery applied in other sectors of national economy, they are distinguished by their design features, performance, and cost-performance ratio. In this regard, diagnostics of mechanically driven parts of agricultural machinery is a key to the overall harvester diagnostics. In practice, health of drives is tested with subjective assessment methods, as a rule. The authors suggest application of a kinematic method for diagnostics of agricultural machinery drive trains during their operation; this method implies analysis of position changes and movement of mating parts: wear of parts and backlash of mating drive parts may be assessed by establishment of geometric parameters of diagnostics (linear and angular movements). The total transmission backlash may be established by dynamic torque appearing in transient states of mechanism operation; such total backlash characterizes dynamic errors in movement of an outlet member, which is a result of dependence of equivalent moment of inertia and drag torque from the velocity transmission error. Such diagnostics of potato harvester transmission allows checking of backlashes in separate sections of the chain, as well as assessment of quality of its components adjustment and maintenance. The research data were used for evaluation of overall engineering state of the harvester and determination of dynamic parameters of its components drives.

Published: September 2020

Abstract
The research has been carried out on the change in the structural composition of leached chernozem of the Krasnoyarsk forest steppe under the influence of plowing with turnover soil and without it in “Acha” barley crops. It was found out that the content of agronomically valuable aggregates ranging from 0.25 mm to 10 mm in size corresponds to the structural state of the soil according to the Williams V. R. gradation. The sample without tillage proved to be the highest structurally coefficient. The content of structural elements larger than 0.25 mm ranges from 78.3 % to 92.5 % and indicates a high wind resistance of the soil. The water resistance of the soil structure of the studied variants in the spring corresponds to an excellent condition. By autumn it is reduced to good condition. Evaluation of the role of individual structural aggregates larger than 10 mm, 5 mm and less than 0.25 mm in the formation of barley yield in laboratory conditions showed that the maximum amount of moisture evaporated from the vessels filled with the smallest aggregates (less than 0.25 mm). In these same vessels, the maximum yield of phytomass of barley was obtained.
