Iron vs Chelated Iron

Don't know how much this applies to Hydroponic gardening seeing as it would be applied to potted plants, but I couldn't find another forum that seemed more suitable to my question.

I was wondering what the difference is between using Chelated Iron vs. regular Iron supplements for potted plants?

Thanks

I have read that iron sulphate (regular iron) isn't very stable at high pH levels.

A Chelate is simply an organic molecule that wraps itself around a metal ion and prevents it's precipitation, increasing it's solubility.
This can be an advantage in hydroponics, but probably not necessary in soil.
Daniel has much more on this at: scienceinhydroponics.com,
But his site has become tricky to navigate.
