If anyone has made or used biochar or terra prita i would like to  
know what your experience was.

Also there is an online conference which someone might be interested  
at this link. http://www.bioeconomyconference.org/  The two speckers  
i'm interested in are shown below.

Plenary Session Speakers

James E. Lovelock, Ph.D.
Dr. Lovelock is one of the world’s most renowned thinkers on global  
environmental science. He has called upon farmers to convert  
agricultural residues to biochar for incorporation into the soil as  
the only solution to global climate change.

Johannes Lehmann, Ph.D.
Dr. Lehmann is associate professor of soil fertility management and  
soil biogeochemistry at Cornell University and co-author of Biochar  
for Environmental Management: Science and Technology. He will discuss  
the combined benefit of biochar for carbon sequestration and improved  
soil fertility.
