Sheez guys you really can't be left alone for a few days can you LMAO
@NaturalFarmer to me it sounds like you're totally misunderstanding what Ingham is saying regarding nutrients in the soil.
You can read up on the principle when Teaming with Fungi comes out - based on a interview I heard, I believe Lowenfels will explain this, perhaps more clearly, with regard to phosphorus and mycorrhizae, in his new book.
Where do you think the minerals in your comfrey came from? I mean, like, originally?
And how did they get out of that hard block of molten lava into a furry plant?
