I love the cloche idea. What else can be used for a cloche?

This has nothing to do with the experiment (which sounds like a great one) but my dad always used to stick a rusty nail in the root wad of a transplant, said they like the iron. Anybody heard of this?
I have. Some plants require more iron to thrive, such as roses and apple trees.

I think a really active organic soil with plenty of humates (especially fulvic acid) could make the iron oxide available to the plants.
Sure, but since iron is a very common element in soil, humic acids would have plenty of iron to chelate even without the rusty nail. The rusty nail to me represents an unnecessary hazard that can send you out to get a tetanus shot without helping the plant. Any iron deficiencies I have seen in plants has been caused by soil issues other than physical lack of iron. It is the bioavailability that is relevant.
