When plowing, the plows produce loosening of the soil and its intense coloring, as a result of which the volume of pores in the processed layer increases many times. In the process of plowing, the natural compaction of the upper soil layer is disturbed, and the internal capillaries are destroyed, as a result of which the treated layer is saturated with air and warms up faster. As a rule, in intensive crop rotations, there is not enough time for soil settling and natural soil compaction. Because of this, it is necessary to prevent drying of the plowed layer.

It is recommended to use soil compactors during plowing together with the plow. The joint use of a plow with rollers ensures the rolling of the processed layer precisely at the time when the soil is still in a wet state and can be compacted to the full depth of plowing. At the same time, good coloring of the layer with the formation of a fine lumpy structure is ensured, which allows to restore capillaries and ensure the approach of moisture to the seed bed, as well as to exclude drying of the plowed soil. It is especially effective when preparing the soil for rape, when it is very important to preserve moisture in the absence of precipitation.

K1U on the front harrow compacts the soil, thanks to which the wheels of the tractor do not fall in and ridges do not form between the wheels. Thus, it provides the best conditions for obtaining a precisely and evenly prepared seedbed. The use of a K1U skid (front attachment) and a seeder (rear attachment) on one tractor gives a high effect and reduces energy consumption when sowing crops by half. K1U can be used for plowing and sowing.
