Optimization of plow adjustment

et al. 2022

The article is devoted to the search for ways to reduce carbon dioxide emissions in the technological operation of plowing. Ways to reduce CO2 emissions were determined on the basis of computational experiments conducted using a mathematical model of an arable unit compiled according to the efficiency criterion - the minimum integral emission of carbon dioxide. Integral CO2 emission, in addition to direct and indirect CO2 emissions over the life cycle of the arable unit, includes CO2, which could be absorbed from the atmosphere by the crop lost due to the influence of the parameters of the unit. The influence of the parameters of the tractor and the unit on the emission of carbon dioxide during its manufacture, technical and production operation is analyzed. Computational experiments were conducted to identify the influence of some external factors (field area, seasonal load volume, etc.) on the efficiency of the arable unit.

Ways to reduce carbon dioxide emissions from arable machinery and tractor units

et al. 2022

“…In addition to freeing up part of the forest area for agricultural needs [7,8], a rapid increase in the number of livestock, an increasingly intensive mechanical and chemical effect on the soil, accompanied by a decrease in carbon dioxide absorption and an increase in the emission of greenhouse gases such as methane [9,10], mobile machines are used in agriculture. This is due to the high level of mechanization, performing a variety of functions and at the same time intensively burning fossil fuels [11][12][13][14][15][16][17][18][19][20]. As a result of the combustion of carbon fuels, carbon dioxide, which is a reference greenhouse gas, is emitted.…”

Study of the influence of various factors on the emission of carbon dioxide by the aggregate during direct sowing of grain crops

et al. 2022

The article deals with issues related to the reduction of carbon dioxide emissions into the atmosphere during the operation of sowing machine and tractor units. To identify ways to reduce CO2 emissions, computational experiments were conducted using a mathematical model of sowing units compiled according to the efficiency indicator. This is the integral emission of carbon dioxide as the sum of CO2 in the manufacture, maintenance, repair, control of the unit, when burning fuel and the amount of CO2 not absorbed from the atmosphere during the formation of the grain crop due to its losses from improperly selected equipment and its parameters. The influence of a number of factors on the integral emission of CO2 is investigated. These are the area of the treated area or field, the specific resistance of the planter, the volume of seasonal load on the unit, the annual load of the tractor in hours, the physical and mechanical properties of the soil, the pressure in the tires of the wheel propulsion engines, etc. Effective values of factors for reducing the emission of carbon dioxide by the sowing unit are revealed. The use of the totality of all the recommendations received will reduce the emission of carbon dioxide into the atmosphere by the aggregate during the technological operation of direct sowing of grain crops by 600-650 kg/ha.

“…The lack of equipment and its ineffective use increase the duration of works and cause grain crop yield losses (up to 25 %) and potatoe yield losses (up to 45 %), etc. [15][16].…”

Energy Justification of the Number of Tractors for Agricultural Operations

et al. 2021

The relevance of the problem under study is due to the need to substantiate the sufficient number of tractors used for various technological operations, depending on the volume of works performed, and taking into account their influence on the crop yield. The purpose is to develop the mathematical model of machine and tractor units used in technological operations by formalizing the vague concept of optimal agrotechnical timing of technological operations and calculating the optimal number of tractors to perform works by the total energy costs. The main research method is mathematical modeling of operations performed by machine-tractor units based on the system analysis and computational experiments and using the energy mathematical model. The article describes a criterion for optimizing the tractor parameters, dependences of the energy mathematical model of the unit. The results of computational experiments showed that for each operation there is an optimal number of tractors and tractor units minimizing the minimum total energy costs. Calculations were carried out when treating 1000 hectares with various tractors. It was revealed that the total energy consumption differs by 2 or more times. The required number of tractors depends on their main parameters, propeller parameters and other factors. It was revealed that with an increase in the volume of works, the required optimal number of tractors increases. The method for substantiating the required optimal number of tractors in technological operations will improve operations of tractors used by large agricultural producers, reduce the total energy costs for cultivating up to 12–16 thousand MJ/ha.
