The purpose of this work is to study the technical characteristics of an aggregate to be scarified under the conditions of the classic soil processing system. When preparing the land for plowing, the following operations will be performed: - checking and removing the causes that can cause the creation of unfavorable conditions for the work of the machines; - the delimitation of return zones and the choice of the most efficient methods of travel; - dividing the land into plots and marking the line for the first crossing. For the performance of mechanized works, the plots are chosen in such a way as to ensure the work for a longer time, without switching to other plots. The minimum plot size must ensure work on at least one shift. After choosing the direction of travel, the turning areas are demarcated at the ends of the plot. At the beginning, the turning area is delimited by stakes, after which a furrow is drawn to a depth of 6 - 8 cm. These traces show the place where the scarifier was moved into the transport and working position. Return areas are worked after the work on the plot is finished. The concept of soil conservation includes a set of activities, measures and technologies that compete to maintain the state of soil fertility without significantly reducing harvests or without high costs. This concept arose from the considerations that the land is the most important means of human existence that ensures the obtaining of food products, raw materials for the energy industry, etc. and consequently maintaining the biological capacity is a necessity imposed by the existence of social life.
