[Gasification] Cool Planets and biochar

We have a gentleman in our village who has a biochar business. Pore size in
the biochar is apparently important though I have not pried into why this is
so. My suspicion is that it has something to do with the uptake and
"holding" of minerals so that fertilizers can be absorbed. As the water
partial pressure reduces as the soil dries out, the pores slowly give up
their water and the minerals at the same time. At least, I think that this
is the case. I once worked on a polymer plant where this polymer could
absorb something like 5x its own weight in water when immersed (read when it
is raining and the soil is sodden). It then gives up the water as the soil
dries out. A wonderful product for arid regions.
What my friend does differently from Cool Planet is that they add
mycorrhizae to the biochar. This kick starts the improvement in soil health
tremendously. If you go and research what mycorrhizae do, you will see that
they improve the delivery of minerals and water to plant roots. A
mycorrhizae count will tell the agronomist the state of the soil's health.

It was nice to hear from you and a nice surprise.
My Web Page is www.fluidynenz.250x.com The latest File is the "Shasta
Gasifier and Charmaker" of my visit at the end of January.
Tom Miles the Consultancy I work with in Oregon is www.trmiles.com
Tom owns these Specialist Group Forums and they are linked to his other
gasification at bioenergylists.org
You can also search out Terra Preta which Tom also runs a Forum for, so
plenty to research.
I will also send a couple of Papers I received last week on biochars, but
remember why I said about the differing production methods affecting
outcomes, because few researchers have any real appreciation regarding the
differences between char groups.
This article below was sent only this week to me, and what they say about
the benefits are basically true. Read the comments after the article as it
offers some interesting other uses for charcoal.
Hope this is of interest,
