Foliar applications of nitrogen have a number of advantages, says Dr. Lailiang Cheng, a Cornell ­University scientist. Combined with tissue analysis, foliar application lets growers respond in a more precise and immediate way than using soil application. Nitrogen can easily be spoon fed to trees in small doses along with their spray program. “Early foliar nitrogen spray is beneficial for fruit set and early fruit growth when leaf analysis the previous years shows less than 2.2 percent leaf nitrogen,” he said.  “Foliar nitrogen sprays can extend the effective pollination period and promote cell division.  The spray concentration has to be […]
