The problem with using terrestrial biomass residues to combat CO2 accumulation
is that there is a limited supply that is available for human use without doing
environmental damage. These consist mainly of crop residues from high yielding
agriculture and managed forests. There are competing use
Ron and other biochar folks,
My impression is that most of the biochar research is focused on use in the
developing world where there is an emphasis on improving soil quality,
particularly of low carbon soils. Carbon sequestration is an important side
effect, but the primary motivation is to i
Geo list, Andrew, David, Marty etal?
The third international biochar conference in 4 years, sponsored by IBI
(www.biochar-international.org) ended today in Rio de Janeiro. In the next
several days, 50 of us will be on the Amazon near Manaus - looking at the
several-thousand year old Terra Pret
Regardless of the debate about carbon efficiencies, there are of course
further dimensions to the issue of crop waste.
The waste contains a wide variety of chemicals, including macro and
micronutrients for plants, which have the capacity to affect yield and
nutritional value of crops in subsequent
I agree with David that whether to bury or to burn depends on details like
whether you can burn the biomass AND bury its CO2, and whether you are looking
at methane or coal as the alternate fuel for generating electricity.
A big problem is that we have too few pilot plants measuring actual perf
Marty,
Thanks for this gracious response.
Sometimes, not often, I miss being back in physics.
Cheers,
