Iron chelate. From Wikipedia, the free encyclopedia. Iron chelate, also known as chelated iron, is a soluble complex of iron, sodium and a chelating agent such as ethylenediaminetetraacetate (EDTA), EDDHA, or others, used to make the iron soluble in water and, for the purposes of agriculture, accessible to plants.ron chelate, commonly present as FeEDTA(Ferric Ethylenediaminetetraacetic Acid), is also used to control broadleaf weeds in lawns. There are a few weeds that are not damaged by FeEDTA and users will likely need a traditional herbicide to accomplish the task.
Applying chelated fertilizers is an easy and practical correction method to avoid this nutrient disorder. For example, the oxidized form of iron is ferric (Fe 3+), which is not bioavailable to plants and usually forms brown ferric hydroxide precipitation (Fe(OH) 3).Ferrous sulfate is often used as the iron source.n the soil, plant roots can release exudates that contain natural chelates. The nonprotein amino acid, mugineic acid, is one such natural chelate called phytosiderophore (phyto: plant; siderophore: iron carrier) produced by graminaceous (grassy) plants grown in low-iron stress conditions.
