Abstract: The research is devoted to diagnostics mineral nutrition of fruit crops, particularly apples and pears, based on related study of soil properties changes, as a result of fertilization and complex of criteria that characterise the quality of plants nutrition. The research was held on the basis of field experiments that studied systems of mineral nutrition of pears and apples, taking the features of soil conditions of the South of Ukraine, age periods, and technology of growth in the lands of Melitopol fruit growing research station named after M.F. Sidorenko of IH of NAAS into consideration. Schemes of the experiments reckon for the study, the effect of application of different doses, methods, and ratios of nitrogen, phosphorus, and potassium in orchards on 4 pear varieties (Vesilna, Pektoral, Izuminka Krimu, Conference) and 2 apple varieties (Idared and Florina). It has been determined that the level of nutrients accumulation in southern chernozem and intensity of their absorption by the trees depend on changes of contents of nutrients as a result of fertilization, and hydrothermal regime of the soil as well. It has been also proved that balanced mineral nutrition increases overall resistance of fruit trees against unfavourable factors.
