dc.description.abstractAgriculture is one of the most important industries, providing the population with food and raw materials for a number of industries represented in almost all countries. The food security of the state and its citizens depends on the state of agriculture. The introduction of automated systems in agriculture will improve, facilitate and make this industry more productive. Determining the depth of plowing is one of the important parameters in tillage, on which the crop directly depends. Soil hardness monitoring is a real basis not only for ensuring energy savings in tillage, but also a basis for the rational use of resources to ensure a good harvest. The main tool for determining soil density is a penetrometer. The analysis of design features of modern models of penetrometers and the main results of researches of working processes in them is carried out. The disadvantages of electronic pin penetrometers are the need to accurately control the depth of immersion of the rod due to the smooth and perpendicular deepening into the ground, which increases the time of one measurement and the whole field, in addition, it is possible to separate the rod in stone and misinterpretation of the data, and some other technical nuances. In addition to technical shortcomings, in our opinion, the disadvantage of the modern penetrometer is its narrow, limited specialization, aimed only at measuring soil density. To study the propagation of ultrasonic vibrations in a medium with different hardness layers, a numerical simulation of the process was performed using the software package COMSOL Multiphysics 5.5. Which will give new foundations for the development of this area.The coordination of the ultrasonic signal emitter and the ground is considered separately. Experimental studies were also conducted to verify the proposed method for determining soil density.ru_RU
