Apples

210  Before establishing a new orchard, apply lime and phosphate to establish a sufficient or high soil test level that will last the life of the orchard.  For additional information contact your County Extension Agent. 

211  Apply 30 to 80 lbs nitrogen per acre depending on size and age of trees.  Adjust nitrogen rate to give desired fruit color and 12-18 inches of growth annually.  Nitrogen supplied as ammonium is preferentially absorbed over nitrates and competes with calcium for root uptake.  Calcium nitrate (15.5-0-0) can be used as a source of both calcium and nitrogen.  Mix 3 lbs calcium nitrate in 100 gallons of water and foliar apply at petal-fall, first cover and third cover.  Same rate should be used for two cover sprays that precede final harvest spray. 

212  This is a boron sensitive crop.  If borated fertilizer is not used to supply boron, dissolve 1 lb Solubor per 100 gallons of water foliar applied at petal fall and first cover.  (When soil test boron is not excessive)

213  This is a zinc sensitive crop.  To PREVENT zinc deficiency from occurring, foliar apply 0.15 lbs zinc per tree.  To CORRECT zinc deficiency which has been verified by a leaf analysis, foliar apply 0.3 lbs zinc per tree.  (When soil test zinc is not excessive) 

214  To convert acre recommendation to per plant rate, divide by 100.

226  To insure adequate nutrient elements being applied, soil test and plant analyze to serve as guides in altering fertilizer recommendations in the following year.

653  Soil test zinc is low, however, this is not a zinc sensitive crop, therefore no zinc is recommended.  (When soil test zinc is low)
