That was not the question,
Red Baron Farms, so I will state it so that it can be added to the growing list of question you are unable to answer:
Restatement of "Where does the 2012 results from Ken Miller of Mandan, North Dakota (No-Till Case Study, Miller Farm: Restoring Grazing Land with Cover Crops) fit in with this time line?"
Ken Miller of Mandan, North Dakota (
No-Till Case Study, Miller Farm: Restoring Grazing Land with Cover Crops) started using multi-species cover crops with grazing
several years before 2012. This
implies that he started using this technique before Gabe Brown's results were widely known.
Red Baron Farms: How Ken Miller learn of the
unpublished Gabe Brown results?
The Gabe Brown YouTube videos and couple of conference web pages seem to be since 2012.
ETA: They are almost neighbors - Mandan and Bismarck are 8.5 miles apart.
