How do you see bio char or terra preta technology fitting in with soil carbon opportunity?
Do you think that the closest sphere of concern that soil cabon opp. has that is commonly known would be carbon credits?
Any ideas on how soil carbon opportunity can be made friendly to the masses?

Soils represent the largest carbon "sink" that people can most easily manage, thus I see the technology has great potential as a carbon offset.

Carbon Credits would be one way to move the technlogy mainstream. I don't think many people are aware of the potential of biochar. let alone what it is, thus if it could be part of that exchange, more people would learn and look into it.

I'm not sure I understand that question. Never thought of "friendly" biochar... But if you mean how could more people learn it's potential, I think doing more research studies showing it's benefits and measuring the carbon stored in soils, measuring how and which toxins it could possibly adsorb reducing pollution in streams/aquifers, discovering which applications are most beneficial (in greenhouse farming? in compost blankets? buried in what type of soil?) how much energy could be produced... and including this information in educational seminars to farmers/homeowners, etc., could be beneficial. It's not a widely known topic or technology. Without lots of research behind it it looks more "faddish" even though it has far greater potential than many technologies promoted now.

I'm new to this. I am participating to learn more on the value of carbon sequestration. That said, my opinion about carbon credit or any type of pollution credit is that it exonerates the polluter instead of causing them to stop polluting. At the same time, education should lead to good stewardship that improves soil fertility vs. having to be paid to do it. Good management is its own reward. If it can make a difference, why aren't we doing it? Obviously there are other constraits which must be addressed. Economic incentives are artificial. Only when it makes sense and becomes heartfelt are people's actions sustainable.
