N. Sokolovsky» popup.description2 The object of research is the optimization of mineral nutrition of agricultural crops through the development and implementation of adaptive systems of fertilizers. The purpose of research is to develop adaptive systems for regulating the trophic regime of typical chernozem of Left-Bank Forest-Steppe High to increase the productivity of agrocenoses, taking into account changes in soil fertility that occur in the long and short term. Research methods - field, laboratory, mathematical and statistical. The teoretical results - the dynamics of fertility indicators of typical chernozem under the influence of different levels of long-term anthropogenic load is determined and the influence of these changes on the productivity of agrocenoses is established; the direction of changes in the fertility indicators of typical chernozem for short-term anthropogenic load and their influence on the productivity of agrocenoses are determined; quantitative and qualitative changes in fertility indicators of typical chernozem in the conditions of aftereffect of fertilizers are established; theoretical bases of adaptive direction in application of agrochemicals are developed. The practical results - adaptive directions of trophic regime regulation of typical chernozem have been developed. Novelty - development of adaptive approaches to fertilizer systems based on new knowledge about the evolutionary changes of soil indicators depending on the intensity and duration of fertilizer and methodological approaches to adjusting the trophic regime of the soil. Effectiveness of implementation - reduction of mineral fertilizers in the main application or transition only to their sowing application, depending on the level of soil security, formed by the use of fertilizers and their aftermath, without losing the productivity of crops. The economic effect is to increase the efficiency of agrochemicals by 10-15% and the profitability of crop products by 15 - 20%. Scope - agriculture.
