Hugh McLaughlin has done much good work on characterizing biochar over the years. He most recently set out to come up with the simplest tests possible that accurately reflect biochar's relevant functions, e.g. enhance soil productivity.
Attached are three well-written papers on Hugh's proposed "Baseline Biochar Metrics":
1) The "Perspective" paper, explaining why these are so needed and welcomed by the biochar community.
2) The actual Metrics themselves.
3) A very lucid spreadsheet "Comparison of European Biochar Certificate Version 4. 8 and IBI Biochar Standards Version 2.0 and Baseline Biochar Metrics Ver IX"
The California Biochar Association welcomes any comments.
