Greetings researchers, in your opinion or experience, what is "the purest" feedstock for biochar production in terms of CNHO to the exclusion of other elements? For example, bone has extra Ca, while maize has P, Fe, etc., etc.
Thanks,

Very interesting question Steven. That way , using indicator plants could be many that can serve as an enruched feedstock for biochar but it remains to seen , to what an extent , such extra nutrients are recovered through final product biochar after anerobic pyrolysis...

As to me there is no as such purest organic feedstock for biochar, but biomass organic feedstock is the best and biochar is defined nowadays on the basis of having biomass feedstock. One of the quest in the present day research is to find biomass feedstock which gives a better yield and improves soil properties.
Biochar has a long history of production and use as soil amendment (several thousand years). Traditionally woody feed-stocks produce higher char yields.

Any sort of matter originated from plants. Hard wood gives better yield of biochar due to high C content.
Hi Jeff, as I mentioned in the explanation, the one with the highest CNOH levels to the exclusion of all other elements.
Thanks,
