Extra-root addition of studied microelements (Mn, Zn, B) and their complexes increased the accumulation of magnesium in leaves on 0,02 (Mn)...0,10% (Mn+Zn+B), in fruit the accumulation of calcium increased on 0,09 (Mn)...0,63% (Mn+Zn+B). The soil addition of microfertilizers and their combinations promoted reduction of copper, zinc and manganese accumulation both in leaves and fruits, at increasing the leaves magnesium content on 0,06 (B1,5)...0,16%(Zn3+B1,5). The extra-root fertilization of fruit trees with three studied elements affects more significantly the leaves mineral composition optimization
