Right. Apparently there is what I guess might be called a "dead zone"  
where carbon does in fact sit in limbo due to lack of oxygen, at a  
level below typical agricultural activity. It is this area that has  
some people exited about the possibility of carbon sequestration.

It's a lovely idea and I wish it could be proved true. High-organic- 
content soil is good for many reasons: erosion resistance,  
microorganism health, drainage, oxygen pathways, and not least, plant  
food production. We who have been gardening this way for a long time  
know the benefits and wish that industrial agriculture would use it.  
Alas, even if agribusiness embraced the concept, I doubt that the  
condition can be optimized to the point of affecting global  
temperature control.
