    The current interest in soil awareness is largely due to the increased importance of growing crops in a changing climate. It is characterized by prolonged droughts, followed by short but intense rainfall, often accompanied by strong winds and low temperatures. In a number of situations and due to insufficient information about the condition of the soil and the applied technologies for its treatment, the latter is not able to absorb rainwater, surface water runoff is formed, which exports large amounts of fertile soil and nutrients. An innovative approach is proposed to perform fast and accurate soil tests using its electromagnetic conductivity. A number of physical, chemical and biological properties can be determined by this method.

    The method of estimation of technological properties of a mobile power tool is presented in the work taking into account the index of its ecological properties. The results of the expert survey are presented to determine the importance of individual indicators in the evaluation of the generalized indicator of the environmental and technological properties of the mobile energy means. Increasing the informativeness of the methodology for evaluating the technological properties of a mobile power tool by taking into account the generalized index of its environmental properties. The structure of the index of environmental properties of depends on the assignment of the estimated energy source and the purpose of the problem to be solved. In our opinion, with a comparative assessment of energy resources as a unit one can adopt the following indicators of their environmental properties. The obtained result shows that today it is more relevant to assess the technogenic impact of a mobile energy facility on the environment than the cost of its implementation unit of work. And with this conclusion, one can not disagree, since the neglect of the impact on the environment in the near future can nullify the economic profit from the production of agricultural products. The evaluation of the importance of individual indicators for a generalized indicator of the ecological properties of a mobile power tool, according to the results of a survey of experts, showed that the most impact is the index of soil consolidation, then mechanical destruction of soil, composition of exhaust gases, pollution of operating fluids, noise, vibration and least impact is a layout diagram of the power tool. The analysis of these indicators allows us to determine which structural-technological or regime parameters of the energy source and to what extent influence the general indicator of its environmental properties. And the more deeply this analysis will be, the most accurate and successful will be proposed constructive-technological or regime measures to improve them.

    Field experimental studies of a new beet tops harvesting machine, which is front mounted on a wheeled tractor aggregating tractor, are carried out, carrying out a continuous non-sensing cut of the green massif of sugar beet tops. At the same time, a new laboratory-field installation was developed, which consists of a rotor type front mounted rotary type machine with a horizontal axis of rotation, a transverse screw for collecting the cutted leaves from all width, and a loading mechanism in the form of a paddlewheel and a loading nozzle. During the field experiments, the tractor moving with a specified speed regime fixed by track measuring wheel, the total cutting height was set in a predetermined interval by means of two pneumatic sensing wheels with adjustment mechanisms. The rotational speed of the rotary cutter, with arched knives mounted on the drive horizontal drum, was varied with the help of replacement asterisks. In the prepared area of sugar beet field, the beet tops was cut at various parameters of the harvesting process, which was then estimated by the size of the remaining tops remnants left on root crops heads and in the aisles. According to the developed program and methodology, statistical processing of the results of experimental studies with the help of a personal computer was subsequently carried out, which allowed obtaining graphical dependencies of the indicated tops residues on the root crops heads, which made it possible to establish performance of new harvesting machine for continuous cutting of sugar beet tops. The established dependencies made it possible to choose rational constructive and technological parameters for harvesting tops by front mounted harvesting machine.
