Abstract: Field experiments of chelated-or Epsom salt-Mg sprays in 1981 and 1982 on ‘Delicious’ (Red King and Starking strains) and ‘McIntosh’ apple trees ( Malus domestica Borkh.) indicated that a minimum of 2 x 2.8 kg Mg/ha, foliar-applied, was necessary to increase leaf-Mg concentration to desired 0.26% levels in ‘McIntosh’. Thus, label-recommended application rates for chelated Mg (2 x 0.56 kg Mg/ha) were too low. ‘McIntosh’ extension growth was increased by adequate foliar-Mg applications, although leaf Ca was reduced in 1 year by the foliar-Mg treatments.
