Keywords: nitrogen nutrition, potassium nutrition, mathematical models of standards, optimal values, arable soils, sustainable management, diagnostic accuracy, phosphate nutrition. The object of research is the main soils of Ukraine, improved theoretical foundations of information and methodological support of systems for sustainable management of nitrogen, phosphorus and potassium nutrition of plants. The purpose of the research is development of theoretical bases of exact information and methodical maintenance of system of sustainable management of nitrogen, phosphorus and potassium food of agricultural crops. Research methods are field experiments, statistical analysis of the obtained data, analysis, generalization and systematization of literary and stock materials, statistical processing of materials of an automated information database. The report contains the results of the developed theoretical justification of the mathematical formalization and interpretation of the assessment of the nitrogen, phosphate and potassium state of the main soils of Ukraine. Mathematical models have been developed for extrapolation and interpolation of data on the content of mobile nitrogen, phosphorus and potassium compounds in arable soils under the influence of natural or anthropogenic factors. Methods for improving the quality of measurements of soil supply with plant macronutrients have been proposed. Theoretical principles of measures to increase the availability of macronutrients to plants have been improved. Promising ways of increasing the availability of phosphorus, potassium and nitrogen from soil and fertilizers to plants have been proposed. Regularities of quasi-stationary functioning of soil trophic systems under conditions of changes in external factors have been established. Product Description popup.authors Yevheniia Y.
