Published: April 2021

Abstract
The article presents the results of experimental studies to improve the productivity and quality of mulch substrate application in the stem bands of perennial orchards. The authors proposed a model of an effective means of mechanization and substantiated the optimal parameters of its operation when performing this operation. In the article the authors presented the results of experimental studies to determine: the productivity of feed and transverse conveyors, geometric parameters of the latter, the distance of laying mulch in the roll depending on the height of its placement above the soil surface and the speed of rotation of the drive drum component mechanisms. The authors proved that to prevent the undesirable excessive accumulation of substrate in the receiving hopper of the machine, the productivity of the feed conveyor should not exceed 5 m3/min. The article establishes that the required application rate is provided by the selection of the optimal operating speed of the unit and the productivity of the feed conveyor and can be 0.03-0.25 m3/m2, and changing the same parameters allows depending on the needs to change the height of the roll within 0.05–0.15 m.

Published: April 2021

Abstract
In this article, we will reveal the opportunities, needs and features of the implementation of environmental strategies in order to motivate the environmental activities of commodity producers in the field of agricultural production. The problem of preserving the environment and ensuring food security in the existing ecological and economic conditions can be solved by achieving optimal environmental management and environmental protection. Improving the relationship between the environment and the economy requires the use of various regulatory tools. The vector of institutionalization of ecological and economic interests should be aimed at correcting certain mandatory actions between the participants of these relations. This includes the active development of approaches that include the integration and combination of information, legal, administrative, economic, moral and ethical tools for regulating nature management and environmental protection. The achievement of the ecological and economic optimum is possible through the analysis of the expected effect and the free conclusion of agreements (contracts) between the subjects of ecological and economic relations and the development of the institute of voluntary environmental agreements using the tools of game theory. The effectiveness of the implementation of integrated eco-strategies can be most clearly expressed in the agricultural sector as the need to produce high-quality agricultural products while maintaining the quality of the environment, especially soil fertility. The trend of consumer choice of organic products in the world continues, grows, determines the growth of the organic products segment and correlates with the goals of environmental policy. In Russia, some of the identified shortcomings and shortcomings of the institutional conditions constrain the growth rate of organic production, but the high potential of its production in the future can significantly change the export orientation of the agricultural sector, increase the competitiveness of domestic agricultural products and become one of the promising directions (vectors) of ecological and economic development of Russia. Organic organic standards is essential for the formation and improvement of institutional conditions of realization of ecostrategy, the main actors (players) which is the complex nature of national and ecostrategy explains the interest and willingness of participants to implement environmental-economic optimization of the activities of organic producers. Depending on the existing norms, rules and standards, the choice of actions of participants in voluntary environmental agreements is associated with individual expectations of maintaining high-quality environmental and economic benefits.

Published: April 2021

Abstract
The influence of the wind regime on the methanol concentration in the city residential area, which is released into the atmosphere as a result of the petrochemical enterprise, is analyzed. The initial data are the data obtained by the automatic atmospheric air control station (AAACS). There are the time series of the methanol concentration changes, the speed and angle of the wind direction for 3 years. The analysis of methanol concentration changes in the air of a settlement depending on the wind regime was carried out. It was revealed that the quality of atmospheric air in the residential area deteriorates with the north, east and south-west wind directions. Three-dimensional diagrams were built. They display the change in the methanol concentration in the atmospheric air depending on two parameters: wind direction and speed. It was found that at a wind speed of 1-2 m /s increase the air methanol concentration in the zone of population compact residence. The ways of methanol intake into the atmospheric air at dangerous wind directions have been determined. It has been established that an increase of the atmospheric air methanol concentration is due to the following reasons: the emission of a polluted gas mixture by a petrochemical enterprise, mechanical turbulence due to the high roughness of the underlying surface, the accumulation of pollutants over a reduced pressure area, in particular, over water bodies.

Assessment of the environmental impact of anti-icing materials on plant bioindicators
Authors: Syutova E A , Dzhigola L A 
Published: April 2021

Abstract
The article examines the physicochemical effect of anti-icing materials, such as sodium and calcium chlorides, XNKM (Russia) and created on the basis of mineral raw materials of the Astrakhan region (AR), on the state of plant bioindicators. The effect of salts contained in various brands of anti-icing materials on the quantitative content of photosynthetic pigments in test objects - tomato and sunflower - was studied. The choice of test objects is determined by the geographic location of the Astrakhan region and natural and climatic factors. The elemental composition of mineral raw materials was studied by X-ray spectral-fluorescent elemental analysis. Analysis of the elemental composition of AR opoka and AR marl makes it possible to exclude the fact that the main content is made up of oxides of aluminum, silicon and calcium, which makes it possible to predict the effective use of the opoka and marl as components of antidepressants. - ironing materials. The studies carried out and the analysis of the results obtained indicate that when using sodium salts and XNKM, there is a sharp decrease in the content of photosynthetic pigments. It was found that when introducing natural mineral raw materials from the Astrakhan region as an anti-icing material: sand, opoka AR and marl AR, the negative impact on the content of photosynthetic pigments is minimal. During the study, it was shown that the content of calcium ions in the biomass of leaves also varies widely; when calcium salts are added, it naturally increases due to the cumulative effect, but since the mineral raw materials of opoka and marl can exhibit adsorptive activity towards cations, the content of calcium ions decreases. Extensive research shows that the most commonly used anti-icing agents reduce the amount of photoynthetic pigments and calcium in plants.

Published: April 2021

Abstract
The air temperature has a significant effect on the warming up of the engine of automotive vehicles. To study this process, comparative experiments on the functioning of tractors in different operating modes were carried out. The value of the coolant temperature was taken as a parameter characterizing engine warm-up. In our studies, the heating of the coolant was considered complete when the temperature at the outlet of the tractor blockhead reached 85 degrees Celsius. The ambient temperature varied from plus 20 to minus 30 degrees. The effect of the load modes of its operation was taken into account on the duration of the tractor engine warming up. The results obtained show that the warm-up of the tractor engine at idle speed has a protracted nature and does not always have a positive result. The process can be intensified by operating the tractor engine under load and using an insulating cover. This reduces the duration of the warm-up process and significantly reduces the unproductive downtime of the tractor.

Using the directed search method to select the degree of centralization of heat supply schemes in order to ensure the environmental sustainability of a settlement
Authors: Yakovlev A V , Nikiforov A G , Kuchumov A V , Terentyev S E 
Published: April 2021

Abstract
An algorithm is proposed for the formalized choice of the degree of centralization of the heat supply scheme in order to ensure the environmental sustainability of the settlement. The algorithm is based on a directed search for combinations of centralization and decentralization of the scheme, with the construction of networks of optimal topology for each of the compared options. The calculation begins with a variant of a decentralized heat supply scheme (maximum number of sources), followed by a reduction in heat supply sources by one at each iteration, up to full centralization to achieve ecological balance in the settlement. Taking into account the directed search proposed in the algorithm and excluding non-optimal combinations at each iteration, the number of calculations is significantly reduced compared to a simple enumeration of options. In addition to practical application, the algorithm allows you to study the “heat load density” indicator, which affects the decision on the degree of centralization of the heat supply scheme, and at the same time take into account the uneven distribution of consumers on the ground, their number, the heterogeneity of heat loads and achieving a balance in the environment.
Method for selecting a source of energy supply in agriculture according to the energy-ecological criterion
Authors: Erk A F , Timofeev E V 
Published: April 2021

Abstract
The choice of a source of electric heat supply in distributed systems is largely determined by the availability or the possibility of delivery of primary fuel and energy resources and economic calculations. Recently, however, more and more attention is paid to environmental protection issues. The aim of the research is to substantiate the methodology for choosing sources of energy supply to agricultural consumers in distributed energy systems. For a comprehensive assessment of the environmental friendliness of energy production, we have proposed an energy environmental friendliness factor. The coefficient simultaneously characterizes the cost of energy production and the amount of generated environmental pollutants. This value turned out to be convenient for comparing a number of production technologies.

Authors: Shakirova V V , Dzhigola L A , Sadomtseva O S 
Published: April 2021

Abstract
The results of the study of the processes of adsorption of cationic flocculants of the “Praestol” brand on sorbents obtained by non-chemical processing of clays of the Astrakhan region, the Volga deposit are presented. The adsorption models of Langmuir, Freundlich, and Temkin were used to describe experimental adsorption isotherms. The parameters of the intensity and efficiency of the sorption process are calculated. A comparative analysis of the obtained constants corresponding to these models is carried out and the most preferred model is determined, taking into account the coefficient of determination. It is established that the Freundlich model is most preferable for adsorption in the cationic flocculant – clay system, which allows us to confidently assume that the surface of the natural materials under consideration contains a large number of energetically heterogeneous active centers and is heterogeneous. The results of the analysis of the adsorption of flocculants on clays showed that this process improves flocculation. The bigger value of parameter of intensity of n from Friendlich’s equation for Praestol 853BC flocculant, confirms a greater influence of sorption on flocculating effect that it is connected with formation of the strong high-viscosity sewed structures on a surface of a firm phase. Experiments on the purification of water from oil by test flocculation were also delivered and the degree of purification efficiency was calculated.
