Zinc sulfate, sugar alcohol zinc sprays improve apple quality

(American Society for Horticultural Science) Researchers calculated the response of apple fruit quality to sprays of zinc sulfate and sugar alcohol zinc to determine whether continuing to supply zinc to trees could increase the fruit quality of "Fuji" and "Gala" apples. Results showed that, although the apple trees showed no zinc deficiency symptoms and the leaf zinc nutrition was at a low level, continuing zinc sprays throughout the growing cycle was necessary to increase fruit quality.
