This YouTube episode (Episode 100 of the Regenerative Agriculture Podcast) is a recorded interview in which guest/interviewer James Johnson flips roles to interview host John Kempf. John recounts his background growing up on a family fruit-and-vegetable farm in northeast Ohio (snow-belt south of Lake Erie), the production challenges in the early 2000s (three consecutive poor years culminating in 2004), and a pivotal field comparison in 2004 where soil with prior pesticide exposure showed ~80% powdery mildew while adjacent, previously dairy-rotated soil showed none. He describes how that experience motivated study of plant immune systems, soil biology, and the founding of Advancing Eco Agriculture in 2006. The episode also notes a roughly one-year sabbatical and that the recording was made on January 18, 2024.
