Iron in higher plants: Storage and metabolic role: Journal ...
Plants store iron for future use as ferritin which is ferric phosphate coated with protein. The protein coat apparently prevents iron toxicity or use of stored iron by pathogens. Iron is found in both heme‐proteins (cytochromes, catalase, etc.) and non‐heme proteins (ferridoxins, nitrite reductase, etc.).

Understanding and Applying Chelated Fertilizers ...
Plants typically utilize iron as ferrous iron (Fe 2+). Ferrous iron can be readily oxidized to the plantunavailable ferric form (Fe 3+) when soil pH is greater than (Morgan and Lahav 2007). Iron deficiency often occurs if soil pH is greater than Chelated iron can prevent this conversion from Fe 2+ to Fe 3+.
