[Terrapreta] Carbon emissions show sharp rise

[Robert Klein]

Hi all

Without question converting forest waste into charcoal and then grinding it to a fine mesh and then drilling it into the soil is a difficult and labor intensive process and certainly was not the way the originators of the process did it.  Their only method was to work with a crop in place that lent itself to the biochar process and can be used today with almost no more tools than the Amazon Indians had.

What this debate is doing is locating more reasons for never using wood charcoal even with modern tools.  That type of charcoal has an immediate value today and cannot be replaced for years.

I remind everyone that the judicious use of corn stalks as described in my postings back in June is capable of putting in excess of one ton of biochar into an acre of soil anywhere that it is possible to produce a crop of corn.  Modernizing this method to work in the industrial farm setting is a  challenge.  Using the method I described can be used today in Africa and anywhere that strong backs are available.

All my posts are available on my Blog at http://globalwarming-arclein.blogspot.com

Most were done in June and July.  I am prepared to volunteer my services to help implement the protocol.

my regards

arclein

Dear list members,

I like Frank's 2 cents worth's observation and Sean's response. Leave
 the
forests to perform their natural function, it is doing it quite well.
 Using
annual growing biomass as the material for biochar production is most
logical. To have more annually produced biomass one could consider the
agroforestry system as an additional source of feedstock for biochar
production. Tree species used need regular trimming and the trimmings
 are
mainly small size material that is in my experience easily made into
biochar. The small size also takes less effort in pulverizing the char.
 .
The end product is unlike the charcoal that is used for fuel and in
 some
countries illegal to produce. The use of more mature or larger wood
 requires
more energy throughout the process as well.

In my part of the world a person would be considered foolish to grind
 up 
charcoal and stick it in the soil.
It is considered too valuable for that and I don't think the Terrapreta
concept would be acceptable, even if people were paid for it. This is
 not
just a technological issue. If there are difficulties convincing  the
'advanced' people of 'civilized' society, try and tell the people in
 the
least developed countries what is happening and what they should do.

Hurry up and show results. Seeing might help believing. Coca Cola has
reached all parts of the world. I hope Terrapreta is accepted faster!
 Maybe
we can get the corporations convinced that saving the planet is a sound
economic policy? I might make quite a difference.
