RE: miccorhizae

Steve

I note that you are dealing with two researchers--one east coast, one west.
One of the 'facts' that I have picked up in my readings is that the
micorhizae of the west are different species from those in the east. So
introducing purchased micorhizae that were harvested in the west into soil
in the east is not a particularly useful thing. 

What has anyone read on this?

The focus is on mycorrhizae, and in response I offered
a 20-page resource list that quickly connects you to
key resources including scientific literature and databases.

You can get that by connecting with ATTRA and
making a request.   

Here are two prominent mycorrhizal researchers:

Dr. Robert Linderman in Corvallis, OR.  He is the chief USDA
scientists for mycorrhizae.  He has published dozen of scientific
papers and given talks all over the world.  He is also down to
earth and practical.  

Dr. David Douds in Pennsylvania is the other mycorrhizal scientist that
I'm communicating with because Douds is looking into mass propagation
of mycorrhizae on the farm. It is done in a trough constructed
from geotextile weed barrier and stakes.  It is filled with
50% compost and 50% vermiculite.  Bahia grass roots
are inoculated with commecial VAM, and when the roots
proliferate through the nursery mix, the mycorrizal grows
into the whole medium.  You have just turned the nursery mix
into mycorrhizal inoculum that can be taken to the field
in wheel barrow quantities and amend to vegetable planting
beds.  Research on field inoculation of peppers with mycorrhizae
showed a 20-30% yield increase.

The NewFarm.org has featured David Douds in a
couple of articles.

Best wishes,
