On October 18 I attended the 4th annual Biochar Expo at the Master Gardeners’ Discovery Garden at River Forks Park in Roseburg, Oregon. The event is organized by Jim Long and his colleagues (MA Hansen and Gani Ruthellen and many more) of the Biochar Study Group of the Umpqua Bio-Alternatives Cooperative. This is always a fantastic biochar learning event with presentations on biochar science and practice, and demonstrations of new backyard and small farm biochar technology. This year I brought a pyramid kiln for sale, and Steve Renquist, the Oregon State University extension agent who manages the Discovery Garden bought it for the gardeners to use.
