Nutritional status of stone fruit orchards in the Swan Hill district, Victoria

Abstract

Diagnostic leaf analysis was used to assess the nutritional status of 22 stone fruit orchards in the horticultural areas near Swan Hill, Victoria. Leaf sampling was continued over the three years 1973, 1974 and 1975 and included apricot, plum, nectarine, cherry and peach trees. Low N and Fe were common to most varieties, very low Zn levels were widespread, Mg tended to be high and low P was characteristic of nectarines and peaches.
