Abstract: Difficulties in controlling the supply of iron to citrus trees when grown in soil led the authors to use of nutrient solutions for this study. Twenty-four nucellar navel orange trees were grown for eleven years in individual tanks of nutrient solutions, out of doors. Eight of them were maintained at high-iron levels by regular additions of iron sulfate to the nutrient solutions. The remaining trees became iron deficient at various rates. Analyses of standard leaves, picked in the early fall season, provided a measure of the changing level of iron nutrition for each tree from year to year.
