The purpose of study: determine the rational parameters of an innovative working body that carries out a high-quality technological process of shallow soil cultivation. An innovative working body for shallow soil cultivation was developed on the basis of nature-like technologies that are currently relevant in scientific research. The ratio when using the golden ratio arises when comparing curvilinear and rectilinear, i.e. natural and artificial forms. The development of a new working body design is based on the physics of the interaction process with the processed environment, using analogies of shape and optimal proportions existing in nature. The working body design for shallow tillage with curved surfaces of increased streamlining using the configuration of natural sliding lines of the treated medium layer during cultivation has been developed. Depending on the required processing depth (6-16 cm), the innovative working body efficiently performs the cutting process with sliding, and also performs flat-cut loosening. Rational parameters and functioning modes of an innovative working body for shallow tillage have been obtained: length – 305 mm; working width – 450 mm; angle of crumbling, sharpening, posterior occipital cutting, mortar, rise – 15, 12, 10, 75-110, 10 degrees respectively; speed – 9-12 km/h.

Operating devices for soil cultivation in arid conditions should not carry the lower layers to the surface of the field, since this leads to the loss of moisture due to its evaporation. Purpose of work is to determine the moisture content in the soil after using new operating devices. There been developed technique of determining the moisture content in the soil after exposure to operating devices by studying the movement of soil layers in the vertical direction and comparing their moisture. The movement of soil in the vertical direction is quantified by a comparative study of the moisture content in the upper and lower layers of the treated formation before and after exposure to operating devices. Using appropriate equipment, there were determined the moisture content in the most susceptible to evaporation surface layer of 0–5 cm and then the average value of the layer-by-layer measurement up to a depth of 25 ÷ 35 cm, depending on the selected operating modes of the operating device.
