The NZ Society of Soil Science has advised that they would be interested in receiving participation from the biochar community in their next annual conference. Details here: http://www.nzsssconference.co.nz/
“The conference welcomes participants with all soil-related interests. If there are a sufficient number of abstracts related to biochar we would try to put them together in one session. You are welcome to send information related to the NZSSS conference to your contacts and encourage them to participate.”
And to keep up to date on other national events, the OrganicNZ event calender may be of interest (but I note they have not got NZSSS conference listed yet). Note the Organic Sector Forum at Taupo in June. It would be great to get a few biochar events on their calender.
