Preservation of soil fertility is one of the main tasks of agricultural production. An important factor of soil fertility is its optimal structure. Under the conditions of intensification of agricultural production, the soil structure, the quantity of agronomically valuable waterproof aggregates, and the spraying of soil are destroyed under the influence of soil-cultivating tools and running gear of mobile machinery. The process of structure formation, the factors influencing it and analyzing the energy criteria for the formation of the waterproof structure are considered. The features that arise during the mechanical treatment of the soil, the effect of processing on its structure and the features of the stress-strain state of the soil are studied. A mathematical model has been developed that makes it possible to calculate the stressed state of the soil and design the most rational form of disk working bodies
