COMMENTS (1, 4, 5, 6, 7, 63, 105, 200, 650, 651, 652) 63 This is a zinc sensitive crop. Fertilizer should contain sufficient zinc to supply 5 lbs zinc per acre. (When soil test zinc is not excessive) 200 Recommended fertilizer rate is for 1 acre. When smaller area is fertilized, reduce fertilizer amount applied accordingly, banded near the drip line for young trees and broadcast for older trees. For 20 year-old or older trees, apply 6 to 8 lbs nitrogen per tree or 100 lbs nitrogen per acre broadcast in February. For younger trees, apply 0.5 lbs nitrogen per year of tree age. Additional nitrogen (10 to 25 lbs nitrogen per acre) may be applied in late May, rate depending on nut set and leaching rain. Excessive growth and no crop usually indicate too much nitrogen has been applied. Reduce nitrogen amount if new terminal limb growth exceeds 12-18 inches per year. To insure that adequate nutrient elements have been applied, soil test and collect leaf tissue in late July for analysis, using the results for formulating the fertilizer recommendation the following year. 651 The soil test boron is low, however, this is not a boron sensitive crop, therefore no boron is recommended.
