Abstract

Magnesium sulfate, applied as foliar sprays at 0.2% Mg, was more effective than THIS Mg in correcting Mg deficiency of Beautiful Arcade seedlings grown in solution culture in the greenhouse. The foliar sprays of THIS Mg chelate (4% Mg) were applied at a dilution of 1:200 (0.02% Mg). Conductivity measurements suggest that absorption of Mg from THIS Mg will occur above 65% RH compared to the level of 80% RH required for absorption from magnesium sulfate.Key words: Apple, magnesium deficiency, foliar spray, Mg chelate, Mg sulfate, THIS Mg
