In a study conducted in 2012–2023, the influence of biologization techniques and basic tillage on the fertility of leached chernozem and the yield of sugar beet root crops in a fallow crop rotation was studied. The potential fertility of leached chernozem ensured the yield of sugar beet root crops against the background of plowing 391 kg/ha, free-fall loosening by 25–27 cm – 392 kg/ha, surface treatment by 12–14 cm – 354 kg/ha. Replacing the employed steam with the sideral one in the specialized beet crop rotation provided an increase in the yield of sugar beet root crops on average against the background of plowing by 28 c/ha, free–fall loosening by 25–27 cm – by 12 c/ha, surface treatment by 12–14 cm – by 21 c/ha. Biologization techniques against the background of applying various doses of mineral fertilizers against the background of dump plowing increased the yield of sugar beet root crops by 10–33% by 25–27 cm, free loosening by 25–27 cm – by 8–19%, surface treatment by 12–14 cm – by 6–22%.
