Does the bag of iron have recommendations for an application rate?

It did not but i did just search this down and i believe it's the same.

I called the company that makes the product. The gentleman I spoke to said one quarter pound of iron per 1000 square feet..........seems reasonable.

Bulkiest chelated iron I found on Amazon was 5 pound. I didn't read the fine print.

Unless you have high pH soil, why not go with Iron sulphate? Much, much cheaper and easier to find.

Last year my soil test showed a PH of 7.5.

I found the iron at a local company that makes it's own brand of fertilizer and they agreed to let me buy just the iron. I have however had two conflicting bits of info on this iron. The guy at the place I'm buying it from called it "Chelated" but the guy at the point of origin said it's not Chelated but works just fine.

I found a better breakdown of what is in it MSDS sheet http://msdsdigital.com/f-227-g-granular-fertilizer-micronutrient-msds

I have a very hard time in Canada finding many of the products you guys down south can just stop into home depot and get.

Yeah too bad you can't get milorganite. Its iron acts like chelated iron. Unfortunately, i believe they've scaled back the iron to 2.5%, down from 4%. I have the same pH. I can tell you non chelated iron does have an effect but not as much or last as long as you might think.

If i add it to my 4 yearly apps of fertilizer it should do the job i would hope.

When I was dropping iron sulfate heptahydrate (20% Fe), I was doing 1lb/1000k sq ft per application, around 3 times a year. Just for reference.

Also, I like soybean meal a lot. But 20lb/1000k.... be prepared for what smells like really bad BO.

I would apply the iron separately. Trying to mix it in with the organic fertilizer to apply them together is very likely to create uneven coverage.
