One of the ways to assess the availability of soil nutrients is the methods of plant and soil diagnostics of plant nutrition. The article presents a brief review of the works and the most significant aspects of the methods of plant and soil diagnostics of plant nutrition: tissue diagnostics, leaf analysis, apiary analysis, express method. The main goal of soil and plant diagnostics is achieved by predicting the response and, to a greater extent, the consequential reflection of the effect of fertilizers on vegetable crops, depending on the zonality of soils. When studying the dynamics of morphological, biometric and chemical parameters of plants during the growing season, a more complete understanding of their need for nutrients is formed. Such information can serve as a basis for the development of measures for the directed impact of nutrition on crop formation. The necessity of using these methods in combination is substantiated, because in such a case these methods provide a more in-depth understanding of plant nutrient availability. Soil analyzes for the content of mobile forms of elements in them indicate their reserves, and by analyzing plant samples, we can judge the rate of entry of nutrients into plants, their need in certain phases of crop development. Given that the biological characteristics of plants leave their mark on the ability of the roots to use certain elements, a system of soil and plant nutrition diagnostics for vegetable crops should be developed. Thus, thanks to diagnostic methods, it becomes possible to predict the effect of nutrition on vegetable crops and to model the growth of the domestic food base.
