Growing peas, winter wheat, corn for grain and sunflower was profitable, and soybeans - unprofitable. The highest economic efficiency indicators were obtained from sunflower crops under an organo-mineral fertilizer system with the use of biological products: conditional net profit - 41945 UAH/ha with a profitability of 131.3%. On average for 2021–2025, the highest productivity in terms of grain units (5.86 t/ha) and digestible protein yield (0.77 t/ha) was when using microbial preparations under the organo-mineral fertilization system of grain-steam-till crop rotation. The higher yield of feed units (7.47 t/ha) was under the constant cultivation of corn for grain against the background of the mineral fertilization system using biological preparations. The highest economic indicators were provided by the 5-field grain-steam-till crop rotation with soybean saturation up to 20% (without mineral fertilizers, using microbial preparations for seed treatment): conditional net profit - 29428 UAH/ha with a profitability of 148.6%. At the same time, soybean cultivation in monoculture (saturation 100%) was unprofitable. The crop rotation factor and fertilization systems over the past 10 years have not significantly affected the humus content in the soil (4.07–4.60% - "high") on the transition to another soil group ("high" or "very high"), according to DSTU 4362:2004.
