N. Sokolovski" popup.description2 The object of the study is the assessment of the balance of the main nutrients when using various factors (fertilizers, soil, crop rotation) on chernozems of various subtypes of the Forest-Steppe in organic production. The purpose of the research is to evaluate of the balance of essential nutrients in chernozem soils, taking into account their ecological and genetic suitability for organic production as a basis for managing the nutrient cycle. Methods of research - field, laboratory, comparative calculation, statistical generalization and systematization of the data. Theoretical results - the regularities of the influence of various factors (fertilizers, soil, crop rotation) on the dynamics of the content of the main nutrients in the Forest-Steppe chernozems under organic production conditions have been established, which have confirmed the leading role of crop rotation and the balance of the fertilizer system in the ratio of nutrients in ensuring their non-deficit balance; the balance of the main nutrients in chernozem soils was estimated taking into account their ecological and genetic suitability for organic production. Practical results - the balance of the main nutrients in the field rotation of the Forest-Steppe is calculated for various fertilizer systems in organic production and it is proved that the use of a balanced fertilizer system, which combines the application of organic fertilizers and plant residues of all crop rotation crops, contributes to the accumulation of nutrients in the soil and ensures their non-deficit balance. Novelty - for the first time, it was proposed to evaluate the balance of the main nutrient elements in chernozem soils, taking into account their ecological and genetic suitability for organic production, as the basis for managing the nutrient cycle. The effectiveness of implementation - increasing the efficiency of fertilizer systems by adjusting the composition of crop rotation, optimizing the doses of fertilizers and biological products and saving fuels and lubricants up to 800 UAH/ha. Sphere of use - agriculture.
