Subject: soil carbon sequestration, the case for woody soil ammendments
To: "[log in to unmask]" <[log in to unmask]>

Dear Amir,

I am member of a French internet forum that is dedicated to the use of
ramial wood chips as a soil amendment in agriculture, in French: Bois Rameal
Fragmenté (BRF).

This technique was firstly introduced by a Canadian forestry scientist
Lemieux, who did a lot of experiments and analysis especially concerning
its properties, notably its tannin and lignin molecules, to decompose into
more stable humus than heavy material does.

Especially in the frame of the discussion of carbon farming, this has the
potential to be a game changer. Basically you can build up soil humus 10x
faster with woody material than you can do with non woody plants.

Now before everybody says "fresh wood on an agricultural field, no way!",
in all experiments, and since more than 10 years there has been a lot in
France, Belgium and a lot of African countries there were no major problems
with nitrogen and certainly not with acidification.

A research promotion paper that explains it quite well, in French, is
attached, from a former student of Lemieux, a belgium guy Benoit Noel.

(page 24)

English articles of Lemieux have become scarce on internet...

So I attach a lecture of him from my own library....... some interesting
theoretical insights for all of us I think , and and the same time very
practical!
