Interesting point. I grow stuff on land that's been mostly undisturbed for 50 years. I tried mychorizal fungus a bit when I started, and then I decided that if it had worked, the stuff must still be in the soil and would "infect" whatever else I put there. I didn't do a good controlled test, but I certainly didn't notice any difference when I started or stopped using it.

Ever seen what they do to the soil to "develop" a subdivision?

Mychorrizal inoculations are worth it. I was skeptical until I did a side-by-side comparison on several rows of potatoes. Pretty impressive results.

Maybe in lightly disturbed soil, there would be no diff. But where the bulldozers have wreaked havoc, some help is noticed.

When I was in hort school the research on mychorizal relationships was still
pretty fresh and I was enthralled to the point of reading a lot of it in
their library just out of curiosity. It was amazing to think that all the
trees in the forest are connected by these fungus which makes the whole
forest seem to be one organism.

When the products came out touting the benefit of applications of these
organisms I assumed that it was just typical marketing BS. The research I
read indicated that these fungus aren't very species specific beyond trees
not having relationships with the same species as prairie plants. The
conclusion was that anywhere trees grow there are already plenty of M.
fungus in the soil, tree compatible, unless it is in a strictly prairie
environment or where strip mining has been practiced. In these sites a few
shovels full of forest soil would accomplish any needed inoculation.

Is there any reason to think anything different?
