The results of experimental studies on the use of the resource-saving organ of the soil cultivating aggregate ROPA as a type of main autumn tillage for sowing spring barley are presented. Deep loosening by 0.40–0.45 m improves the agrophysical properties of the soil, contributes to better assimilation of atmospheric precipitation in the autumn-winter period, thereby improving the moisture supply of the root layer by 25% and increasing the fertility of the arable horizon. Using the proposed cultivation allows obtaining up to 1.77-1.79 t/ha of spring barley grain in semi-desert conditions of the Northern Pre-Caspian on old arable lands.
