An automated system for adaptive regulation of soil density has been developed, which makes it possible to improve the quality of garlic incorporation when planting within the range of soil density regulation in the range of 1.2 -1.4 g/cm?. A methodology has been developed for conducting experimental studies of a machine for planting garlic with an installed automatic monitoring and control system for regulating soil density during planting. The results of experimental studies of the uniformity of soil compaction using a compaction roller with an automatic density control system and a closing device represented by a skid-type harrow indicate that after passing through a skid-type harrow, the value of the studied parameter increased by 18% relative to the initial state of the soil. The results of experimental studies of the quality indicators of the planting machine without an automatic monitoring and control system indicate a deterioration in the quality of the process of planting garlic bulbs with increasing forward speed in the range from 0.8 to 1.2 m/s at values of the coefficients of variation of the depth of planting of garlic bulbs ?_Hl from 32% to 42%. The results of experimental studies of the influence of a digital system for automatic control and management of garlic planting indicate the prospects of conducting research in this direction, which is confirmed by an increase in the quality indicators of the planting machine by 15% in comparison with the closing organ in the form of a skid-shaped harrow.
