I’ve had a dialogue going with Oxford Biochar since early last year about expanding their project into NZ and SEA. They have had quite a few of these inquires and are keen to collaborate but have been hampered by a lack of resources. We plan to re-engage on the subject soon. I hope we can pull together a NZ version of this work. This could be as simple as local gardeners signing up to the UK site or a collaboration on a new local project. We need to sort out NZ biochar supply issues but that will be an exciting challenge for aspiring local producers.
The biomass used for biochar, its preparation, biochar production methods and process conditions, along with pre-application processing, create numerous variables even before you get your biochar in the garden. These variables could be reduced to some extent by providing the same biochar to all participants… but then we would only be testing one biochar.
I like the idea of opening the project up to all potential biochars with data gathered on their production. Maybe project funding could be sort to test each char as a science collaboration.
