Chelated

Chelated is referred to in metals. For example chelated iron.

This word means a chemical compound in the form of a heterocyclic ring, containing a metal ion attached by bonds to at least two nonmetal ions.

This chemical process renders the metal absorbent and non-toxic to plants and most life on the planet.

The chelating agents vary - a common synthetic chelator is EDTA.


 * Quite often water conditioners contain a chelation agent to render any potential toxic metals in the tap water harmless and prevent metal poison disease.


 * Plant fertilisers like PMDD or commercial products contain chelated metals for good plant growth.
