Hello Hugh -|
Thanks for sending the images of root growth and your
thoughts. I guess they didn't make it on the BD-Now
archives, so I've copied your "text" below.
I'm fascinated by the simple observation method that you present.
Roots and rhizosheres and associated microorganisms are topics
that I've spent years looking into and thinking about.
I'm not sure if you suggest those rooting patterns are
VAM-derived hyphae radiating outwards, or maybe
you suggest that VAM-colonized roots are stimulated
to *proliferate*, in the zone that you describe.
Regardless, my ears are pricked up and will keep
thinking and learning. I've got tremendous respect
for the BD farming experience you and others bring to
The following online book from Australia is superb.

Especially see Section 3. on VAM, and the following
Section 3. ARBUSCULAR MYCORRHIZAS
"The network of hyphae in the soil is only connected to roots
by the entry points that initiate (VAM) mycorrhizal associations,
as hyphae do not grow out of living roots."
Also see Section 4. on Ectomycorrhizas.
Section 4. ECTOMYCORRHIZAS
I'm still open to your observation-based method,
but wondering how it jives with the vasicular arbuscular
mycorrhizal knowledge base.
Interestingly, Walter Goldstein's research on BD
influence on rooting patterns might be relevant to
There are definitely differences in rooting patterns
based on organic matter, soil biology, and humic
