Abstract
Greenhouse and field studies with foliage sprays of 3 per cent ferrous sulfate solutions provided excellent correction of iron deficiencies in grain sorghum. Greatly increased yields also followed treatment in severely chlorotic areas. Although effective, the large amounts of ferrous or ferric sulfate required for soil applications proved economically impractical.
