Did you read this part?
Mycorrhizal fungi live in the soil on the surface of or within plant roots.
On the surface of the soil is news to me, I wonder what microbeman will say.
And after reading this paper I wonder if in no till horticulture if we should add more carbon, or if the peat and leaf mold are plenty....scrappy
I think they mean this....
"... on the surface of or within plant roots."
Surface of roots.... not the soil. Yeah?
