He talks about what the earliest zero till adopters were told, why he never believed a field needed fifteen management zones, and his long-held argument that carbon dioxide is agriculture's most overlooked plant nutrient. He is candid that the concepts he became known for explaining were the ones he had to boil down to understand himself. Henry died in 2024 at eighty three. The episode stands as a full record of how one of the Prairies' most trusted soil voices actually reasoned.\n"}
