Abstract
SummaryThe concentration of P in cv Bramley’s Seedling apple leaves was increased by phosphate sprays in four orchard experiments. The effects were shown in three different leaf positions and at two sampling times, but the differences decreased with time after early spraying, indicating redistribution within the tree. KH2 PO4 sprays sometimes, but not invariably, increased the leaf K concentration and reduced leaf Mg. Ca(H2 PO4)2 did not affect the concentration of any nutrients measured other than leaf P. Leaf Ca levels were supplemented by late season applications of CaCl2 but, in one experiment, this treatment decreased leaf K.
