“…Sapropel can be used in the agricultural sector, using it as a fertilizer that allows you to increase soil fertility, restore depleted soils, significantly increase crop yields. Sapropel is not only used to fertilize the soil, achieving significant plant growth and saturation of the soil with useful elements, but is also used to feed animals and birds, stimulating growth, strengthening the skeleton, improving metabolism and immunity of young animals [6][7][8][9][10]. The fertilizer does not contain pathogenic bacteria or weed seeds and is suitable for all types of soils and crops.…”

The concentration of means of production directly related to land largely determines the level of intensity of land use. The development of the territory is largely determined by the availability of material resources, they determine the structure of production activities and the level of well-being of the population. The article deals with the analysis of the development of the territory of the municipal district on the use of the land patent, the strategy of development of the territory.

The current paper has presented the study on theoretical dependences of the optimization parameter (the degree of transmission transparency) on the design factors of elastic-damping mechanism (EDM) in the transmission for tractors of small traction class (14 kN). The purpose of the study was to obtain a unified functional relationship that integrates early study results. The determination of a unified function was based on reaching a compromise by the method of indefinite Lagrange multipliers. With the help of the function, there have been obtained the dependences of the effect of EDM design factors on transmission processes when performing the main agricultural operations. Using a method based on finding a compromise solution (method of indefinite Lagrange multipliers), there have been substantiated design parameters of the elastic-damping mechanism in the tractor transmission and there has been identified an optimization parameter of the Lagrange function. For a better understanding of the obtained dependence, there has been carried out a three-dimensional visual analysis. Each factor used in the Lagrange function was a physical parameter of an elastic-damping mechanism. The resulting equation has given an opportunity to control mechanism parameters in natural operating conditions. The obtained Lagrange value has demonstrated that the mechanism absorbs 32% of fluctuations in the external traction load of a tractor, when working with the main agricultural tools.

“…However, it also needs to be correctly selected based on certain soil characteristics. There are many tire models that are presented by authors in [4,5]. In these works, a very accurate tire model is described that describes their behavior in the contact area of the tire with the ground for both longitudinal and lateral stiffness of the tire.…”

To automate the process of harvesting crops, different types of harvesting machines are required. The most common type of machines used to automate ingathering are harvesters. The use of harvesters for collecting grain crops is rational in fields from 2 hectares. On smaller areas it is not profitable and difficult to apply. For applications in small areas, low-capacity harvesters with a throughput of the thresher up to 1 kg/s (small-sized) may be suitable. The purpose of this study is to analyze the cushioning mass control system of a low-capacity unmanned combine harvester using computer simulation, as well as the simulation of directional stability and turning. To calculate vertical vibrations in the Matlab/Simulink software package, a model of a cushioning system for a wheeled agricultural combine was prepared. In the same software package, simulation of directional stability and turning implementation was carried out. The parameters of vibration displacement, vibration velocity and acceleration, as well as the vibration frequency indicators on the operator's seat are determined. Comparison of the simulation results of the initial and corrected direction of movement of the harvester showed that for this model the maximum deviation from the planned path is a maximum of 10%, which is within acceptable limits. The maximum deviation of the harvester from the course does not exceed the permissible values, which is acceptable accuracy to ensure directional stability.
