Kathleen Draper was recently in Oz to talk about her work with biochar. She was a guest speaker at the Mullumbimby bio-charfest (some reports on the fest from their facebook page). She has worked extensively with biochar in vineyards… a link to an online presentation on this work is here.
ABC interview with … “Kathleen Draper is director of the Finger Lakes Biochar in the US and is working with small-scale biochar producers to develop closed-loop biochar systems”
She also has some really interesting ideas to share on more exotic uses of biochar which are being covered in the Biochar Journal.
