In a chelated micronutrient mix I use, it lists EDTA chelated Iron at 5% and DTPA Chleated Iron at 2%.

In laymans terms, what does this mean?

Can I assume that it has 7% usuable iron?


It also lists EDTA ethylene diamine tetra-acetate at 42% and DTPA diethylene triamine pentaacetate at 13%. What does this mean to me?

... or more specifically.. what SHOULD it mean to me?
