The only experience I've had with the iron issue is with trees. Back home in
Colorado, the soil just robs the iron from them, especially maples. They
turn in late July sometimes. We used injectables at the base roots. I am
meeting with our local extension rep from Purdue Ag Dept next week. I'll
pick his brain for you and get back to you. Sorry for the late reply...3
kids, two jobs, danged tractor problems, pumpkins and a very dear wife that
I think can't wait until winter!

The pH of the soil is 7.8-8.0 depending on where I take my samples from.
The option of reducing my pH is not an option...to much buffering to make a
difference, but local microenvironments can be changed for a short period of
time. The high pH and cold soils early in the season will cause iron
chlorosis. I did have a tissue sample taken this season and it was
confirmed iron. The soil test is high in iron, but apparently it is plant
unavailable during that time frame due to the cool season. What foliar iron
products have people used to alleviate the visual symptoms?

I did not read every portion but I have to assume you have not done a foliar
analysis at a lab? Without this, you really cannot determine what is going
on. Get that done and I think the light bulb will go off. When I did my
foliar, I came upon issues that nobody knew about and ever dealt with here
in the desert of AZ. It was truly enlightening.
Really, don't assume anything and get the test.
Good luck!!!!!!
