Autumn,
Regarding research, Sir Albert Howard in the early part of last century
(and others) found Mycorrhiza (M~) to be essential to the health of many
plants, and that species-specific M~ is required for some.
So its not that one M~ fits all!
Obviously, if the required M~ for the trees you are planting is already
present, there is no need to add it. If it isn't, I consider it to be
imperative!
Further, if its there or its been added and the crop is not performing
well, I would be looking at other possibilities ( espescially in the
soil: organic matter, soil food web, etc) -
Just my take on it, I'm no expert.
