The effectiveness of two chelated zinc compounds in correcting zinc deficiencies was studied. Soil and foliar treatments were made to study possible residual zinc carry-over from one season to the next. Foliar treatments at various rates were applied to raise plant tissue zinc levels above deficiency levels. It was found that none of the treatments studied resulted in any substantial carry-over of zinc to the following year. All of the foliar zinc treatments resulted in an increase in leaf zinc content in all of the varieties of fruit studied. The level of zinc in the treated trees increased in proportion to the amount of actual zinc applied. All zinc treated trees remained above critical zinc deficiency levels during the season treated as opposed to the untreated trees.
