Gardening with Biochar FAQ (Wiki)
Philip Small, May 21, 2008

Welcome to a Gardening with Biochar FAQ!
... a work in progress...

When gardeners add biochar to garden soil, we are, in effect attempting to follow in the footsteps of the originators of Terra Preta. Because we don't know exactly how that process worked, nor how we can best adapt it outside its area of origin, we are left to discover much of this by experimenting with our own gardens and comparing observations within our own communities.

Dear friends: terra preta is fascinating in part because it involves so many disciplines. My viewpoint is that of a fuel scientist/chemical engineer.

My laboratory produces well-characterized charcoals for a wide variety of research endeavors, including carbon fuel cell studies, metallurgical charcoal applications, activated carbon production, and terra preta research (with my colleagues Dr. Goro Uehara, Dr. Jonathan Deenik, and Tai McClellan in the University of Hawaii
