With requests arriving to list fully commercial products, ABE probably needs to upgrade its policy on product endorsement. Well, we do not currently have a policy so I’d be keen to hear any views. This list was developed for the benefit of local biochar enthusiasts who are unwilling or unable to produce their own biochar for their gardening / horticulture / farming experiments. We would also like to see a growing and healthy market and fully commercial biochar production and application industries in NZ.
Biochar made from twigs of acacia melanoxylon trees (Tssmanian blackwood) and some from arundo donax (giant reed). Not crushed. Stored in drums or plastic rubbish bags. I have neither time nor expertise to do more than very crude trials of including it in compost, but would be pleased to meet with locals interested in doing further work and advancing the movement.
