Re: Mycorrhizae
You can also get some of these benefits directly from compost or "brewing" an aerated compost "tea" with compost. There are many claims out there, though many are not backed up by studies, etc. (though some are). A compost with a lot of brown material will usually have more fungi which is generally considered more suitable for trees, shrubs, etc. for reasons I don't honestly remember.
