Studies were conducted to determine the effects of iron and zinc chelates on these deficiencies . Soil treatments, and foliar treatments with and without urea were used . It was found that in soil treatments at least one pound chelate per tree must be used to significantly increase the iron content of the leaves. The soil treatments did not re~lt in as high a concentration in the leaves early in the season, but they had a residual effect that lasted throughout the entire growing season. Foliar treatments with iron did not effect the foliage that developed after the final application was made . In the conditions of this experiment the application of iron and/or zinc chelates resulted in increased peach size, soluble solids and sugar content.
