I was going to suggest that you test the iron levels in your drinking
water (assuming you drinks from the tap, and not bottled H2O). Any
LSF will carry Iron tests. This may help you know just how much iron
you have comming from the pipes...

That's the reason fertilizers contain "chelated" iron. It's iron in a
form easily utilized by plants.

Will the "non-chelated" skew the Fe test results?

I didn't realize that there was a difference between the 2 irons.
Thanks Chuck.
