I've heard the same thing as Mike with Fe products causing early abscision. Some companies who do it regularly only do it in the fall.
Have you tried the vert mulch with a strong acid? I know a few people in S/E WI who still do it, one calls it "Root Beer Floats" because of the way the soil foams when you poor sulferic acid into the holes.
From what I've been told, you do it out where there are mostly fine fibrous roots. The Fe and Mn will be released and fine roots will colonize the area untill it buffers down again.
Arbotech has low enough pH to it that I've often wondered about making a fert that is very low, such as a humic acid, in a soil injection.
