Intensive farming has caused soil degradation, including the loss of humus, soil structure breakdown, compaction, and a decrease in both potential and effective fertility. Therefore, research into farming systems is highly relevant. In this regard, the purpose of this study is to scientifically substantiate, develop, and implement an ecologically friendly modern farming system under Ukrainian conditions. The primary methods used to determine the effectiveness of various farming systems and ensure the accuracy and reliability of experimental data were field, laboratory, and statistical methods. The study substantiated that an industrial farming system with the input of approximately 12.0 tonnes per hectare of crop rotation area of organic matter (8.0 tonnes per hectare of manure and 4.0 tonnes per hectare of plant residues) produces about 0.81 tonnes per hectare of humus, although 1.33 tonnes per hectare of it is mineralised, leading to a negative humus balance in the soil. The output of grain units in this system is 8.21 tonnes per hectare, feed units - 9.63, and digestible protein - 0.86 tonnes per hectare, with stability at 91.2% and profitability at 88.0%. The organic farming system, which includes the use of 24 tonnes per hectare of organic fertilisers and biological products to control weeds, diseases, and pests in agrocenoses, does not ensure a positive humus balance in the soil (-0.14 tonnes per hectare) and has significantly lower productivity. The no-till system, which involves the application of 12 tonnes per hectare of organic fertilisers in the form of root and stubble residues, by-products of crop production, and mineral fertilisers during sowing and foliar feeding, ensures a positive humus balance (+0.12 tonnes per hectare) but has productivity levels comparable to the organic system. The ecological system provides stable, economically viable, and resource-adequate productivity of arable land, enhances the quality indicators of products, and preserves and restores soil fertility. It increased the output of grain units by 8.9%, feed units by 7.2%, and digestible protein by 8.1%, ensuring high stability at 94.1% and an increase in production profitability by 8.5% compared to the control. The materials in this study are of practical value for agricultural enterprises of various ownership forms and will serve as technological guidelines for the implementation of modern, ecologically safe, economically and energetically justified agricultural production.
