During plowing and surface treatment, a high level of correlations is established between mineral nitrogen, mobile phosphorus and exchangeable potassium (R>+0.70), and the use of nutrients (Р2О5 and К2О) is 1.2–1.4 times higher than that of mineral nitrogen. On average, during the vegetation period, the concentration of CO2 under plowing was 728 ppm, under plowless shallow tillage it was higher by 37 ppm, and under No-till systems it was higher by 15–25 ppm, which indicates the biological activity of the soil. In the conditions of 2025, the productivity of the 5-tip crop rotation in terms of yield of grain units was: for plowing 6.09-6.87 t/ha (plowing) and 6.2-6.68 t/ha (surface tillage), while for No-till the yield was lower by 2.14-2.70 t/ha. For the application of fertilizers, the net profit for plowing and surface treatment was 18.46–18.80 thousand hryvnias/ha, and for No-till it decreased by 1.23–1.26 times. The average profitability of production under plowing was 135.6%, while under surface cultivation it increased by 11.4%, and under No-till it decreased by 18.0–18.4%, relative to plowing and by 29.4–29.8%, relative to surface cultivation.
