Ways of Making Terra Preta: Biochar Activation

I am linking in this article by Hans-Peter Schmidt on his ithaka website. Hans-Peter is a leader on biochar in Europe and he writes well on a range of biochar application subjects. I plan to link into more of his articles where they may overlap with biochar applications in NZ agriculture.

This article is not about biochar production but using a range of methods to ‘activate’ or ‘charge’ the biochar prior to soil application. Designer biochars.Capture - char closeup

Biochar is not a fertilizer, but rather a nutrient carrier and a habitat for microorganisms. First of all, biochar needs to be charged to become biologically active in order to efficiently utilize its soil-enhancing properties. There are numerous methods of activating and producing substrates similar to terra preta aside from mixing biochar with compost. …”
