[Stoves] Fwd: Biochar is making its way into the oceans, apparently

[Frank Shields]

Hi Paul,

 

After a wild fire a group for trail repairing I was involved with was first
allowed to enter. It was tough going as we walked we would fall through a
hole where the roots burned underground and still smoldering a couple weeks
after the fire had been put out. I think this is where the biochar is made.
Also; in the lab testing biochar the char dust will go through the finest of
filter papers to need be later cleaned before introduction to lab
instruments. Travel with water? Perhaps or just disappear into the soil
structure. 

 

Regards

 

Frank

 

Thanks

Most of the charcoal in nature is from wild fires and combustion of biomass
in general. When charcoal forms it is typically deposited in the soil.“ From
a chemical perspective, no one really thought it dissolves, but it does,”
Jaffé says. “It doesn’t accumulate like we had for a long time believed.
Rather, it is transported into wetlands and rivers, eventually making its
way to the oceans.”

If biomass is burned, and if afterwards the charcoal from this burning
remains on the surface of the ground, how is it supposed to accumulate in
the soil? How is charcoal "typically deposited in the soil" from a wild
fire? Wildfires do not till the soil and mix in char in a uniform manner. 

If biochar is properly mixed into the top soil through human activity, this
is an entirely different matter. It seems likely that it would be washed
away in a large rainfall event only if the top soil in which it were
incorporated were washed away.

Thanks.

Dear Friends of Biochar

 

This will probably be of interest. I am posting here because of the biochar
enthusiasm and because I am not subscribed to any biochar lists. 

 

Regards

“
According to the authors, the results imply that greater consideration
must be given to carbon sequestration techniques (the process of capture and
long-term storage of atmospheric carbon dioxide). Biochar addition to soils
is one such technique. Biochar technology is based on vegetation-derived
charcoal that is added to agricultural soils as a means to store carbon.

 

Although promising in storing carbon, Jaffé points out that as more people
implement biochar technology, they must take into consideration the
potential dissolution of the charcoal to ensure these techniques are
actually environmentally friendly.

 

Jaffé and Dittmar agree that there are still many unknowns when it comes to
the environmental fate of charcoal, and both plan to move on to the next
phase of the research. They have proven where the charcoal goes. Next, they
want to answer how this happens and what the environmental consequences are.

The better scientists can understand the processes and the environmental
factors controlling it, the better the chance of developing strategies for
carbon sequestration and help mitigate climate change.”
