In long-term stationary experiments on fruit-bearing bushy apple trees of the Bogatyr’ variety in the conditions of leached chernozem the authors analyzed the chemical composition (the content of nitrogen, phosphorus, potassium, calcium, magnesium, amino acids, sugars, anthocyanins, chalcones, pectins) in fruits against the background of application of foliar nutrition by mineral fertilizers and humic preparation of new generation, obtained on the basis of peat. It was shown, that after nutrition the content of main nutrient elements in fruits is increasing.

Keywords: apple-tree, chemical compound of fruits, fertilizers, foliar nutrition, stimulators.
