Biochar Feedstock Origin Research


Harry Groot
 

Has there been research published looking at a comparison of biochars based on specific feedstock origin?

A question challenging the value of biochar produced from bark and slash as opposed to roundwood was raised during interviews with forest managers in MN.  The practice of making biochar seems to be rather agnostic for woody biomasses, but it made me wonder how the characteristics changed if the feedstock was exclusively one source or another--in this case, bark or slash as opposed to whitewood.

Thanks for your help,
