To theoretically substantiate modern systems of basic tillage in crop rotations of the left-bank Forest-Steppe with efficient use of crop by-products.

As a result of the conducted research, baseline information has been obtained regarding the dynamics of soil fertility indicators depending on minimized soil tillage systems in crop rotation.
It has been determined that the maximum grain yield of winter wheat – 5.6 t/ha, spring barley – 4.61 t/ha, corn – 8.95 t/ha, and soybean – 3.92 t/ha was achieved using the ridge tillage system.
Thus, it was established that, on average across the crop rotation, the content of easily hydrolyzable nitrogen compounds in the soil layer of 0–20 cm was at the same level across different soil tillage systems (181.0-182.0 mg/kg of soil for easily hydrolyzable nitrogen compounds (average content)). At the same time, in the soil layer of 20–40 cm, lower nitrogen content levels were observed under the Mini-till and No-till systems by 7.7–7.9%.
The results of the research indicated that in the 0–20 cm soil layer, the content of mobile phosphorus compounds in the classical tillage system was 151.3 mg/kg of soil (high supply), and it was higher by 1.4-2.9% under Mini-till and No-till systems. In contrast, in the 20–40 cm soil layer, it decreased under the Mini-till and No-till systems by 6.8–7.2%.
The content of exchangeable potassium compounds in the 0-20 cm soil layer under zero tillage was 180.5 mg/kg of soil (high), which exceeded the corresponding indicator in the classical tillage system by 4.4%. Meanwhile, in the 20–40 cm soil layer, the classical tillage system showed potassium levels (160.0 mg/kg of soil) that were 5.6-7.2% higher compared to the Mini-till and No-till systems.
