Iron Deficiency

Symptoms:
Iron-deficient plants are yellow and stunted, with the symptoms expressed on the young leaves first. Affected leaves have interveinal chlorosis, with the leaf lamina at first appearing to be a "healthy" yellow.

Control:
Conduct soil and/or foliar nutrient analysis to confirm that the problem is nutritional. Follow recommended practices for fertility using a balanced fertilizer. High pH soils often induce iron deficiency by holding iron in an insoluble form. Powdered sulfur applications may be used on limited areas to lower pH. A number of chelated iron compounds are available for spray application.
