Nectarines

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.

220  Apply fertilizer 6 weeks before anticipated bloom.  Adjust nitrogen fertilizer to obtain annual terminal twig growth of 12 to 18 inches, normally obtained by applying 40 to 80 lbs nitrogen per acre depending on age and vigor of trees.  Split nitrogen applications with second nitrogen application applied after fruit set.  If trees indicate nutrient element supplies have been exhausted when harvest complete, sidedress 10 to 15 lbs nitrogen per acre using calcium nitrate (15.5-0-0). 

221  This is a zinc sensitive crop.  To correct or prevent zinc deficiency, foliar apply chelated zinc as label directs or dissolve 3 ounces zinc sulfate per 100 gallons of water as a foliar spray three times at 3-week intervals.  If a fungicide containing zinc is used, additional zinc not required.  (When soil test zinc is not excessive)

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.

651  The soil test boron is low, however, this is not a boron sensitive crop, therefore no boron is recommended.  (When soil test boron is low)

224  This is a boron sensitive crop.  For peach orchards, apply 0.5 lb boron per acre in the fertilizer every 2 to 4 years or as an annual foliar application of 0.2 lbs boron per acre.
