Abstract

The composition contains iron EDDHA and for iron EDDHMA in an agriculturally-acceptable organic solvent, preferably ethylene glycol. The composition is used in treating iron deficiency in soils and can have an iron content of up to 40 or 50 g dm.sup.-3. The composition may also contain considerable amounts of water yet still to be stable at room temperature, the aqueous composition having a significantly reduced viscosity relative to the water-free composition. The iron chelate need not be dry when incorporated into the composition. It may also be synthesized in situ in the solvent of the composition.
