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.
For example, at high concentrations, calcium or magnesium ions may replace the chelated metal ion. Fe-EDTA - This iron chelate is stable at pH below 6.0. Above pH of 6.5, nearly 50% of the iron is unavailable. Therefore this chelate is ineffective in alkaline soils. This chelate also has high affinity to calcium, so it is advised not to use it in calcium-rich soils or water.
