It was at this meeting that Arthur Wallace of UCLA and Harry Kroll of Geigy met on a brain-storming session aimed at dreaming up the structure of a stable iron chelate.
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.
