Stephan, thanks! What I’ve seen is that the metals in biomass tend to get concentrated in the biochar fines during the pyrolysis process. Have you seen this effect? May suggest that fines are better f

Limited work on best biochars for rhizodeposits but animal manure and straw seem to work best Some work on aggregates adn biochar. Google scholar will help. But here is some Incorporation of Biochar C

Hi Stephen, Are there certain types of biochar that more-readily protect rhizodeposits and form aggregates? Pyrolysis vs gasification? Biomass type? Is there an analysis that can be done on the biocha

Jurgen, my understanding of biochar is that as it ages in the soil, it oxidizes. I can see how gaseous ozone would accelerate the process. Not familiar with any studies. Rick

Tom, Thanks this abstract. Wonder if putting wood char and bone char in hydrogen peroxide would achieve a similar oxidation outcome, as well as, just bone char in hydrogen peroxide......... my 2 cents
