Rolling after sowing accelerates the process of warming up the soil, which contributes to the inflow of soil moisture from the lower layers to the upper ones. It should be noted that the compaction of the surface of light chestnut soils of Buryatia during a dry and cold spring is the most effective method in preserving soil moisture from evaporation, improving the temperature and nutritional regimes of the arable layer. Due to this, rolling helps to increase the yield of many agricultural crops. The most useful is the rolling of the soil with ring rollers, but it must be borne in mind that a large gap in time between rolling and sowing should not be allowed, otherwise the risk of wind drift strengthening of soil particles increases. Thus, the technological operation of continuous post-sowing packing generally provides loosening and compaction of the surface layer. For this, various types of agricultural rollers are used, among which star-wheeled rollers are most widely used. When choosing the parameters of the rollers, it is necessary to take into account the dimensional parameters of the soil clods, as well as the distance between the lugs and the allowable displacement of the lugs. To increase the effectiveness of the impact on the soil in depth, it is advisable to use a roller with fourth lugs compared to a roller with two lugs, which provides a relative increase in the area of impact on the soil.
