Show overview
Regenerative Agriculture Podcast has been publishing since 2018, and across the 8 years since has built a catalogue of 226 episodes. That works out to roughly 230 hours of audio in total. Releases follow a fortnightly cadence, with the show now in its 24th season.
Episodes typically run an hour to ninety minutes — most land between 50 min and 1h 14m — though episode length varies meaningfully from one episode to the next. None of the episodes are flagged explicit by the publisher. It is catalogued as a EN-language Science show.
The show is actively publishing — the most recent episode landed 1 weeks ago, with 27 episodes already out so far this year. The busiest year was 2024, with 56 episodes published. Published by AEA Marketing.
From the publisher
This is a show for professional growers and agronomists who want to learn about the science and principles of regenerative agriculture systems to increase quality, yield, and profitability.

S8 Ep 9Podcast Extra: Adjusting Nitrogen Management with John Kempf and MSHC
In this webinar for the Minnesota Soil Health Coalition, John Kempf discusses a paradigm shift in nitrogen management . John outlines how moving away from high-electrolyte "chemistry" fertilizers toward biological nutrition can build crop resilience and significantly reduce input costs . By understanding how different forms of nitrogen, such as ammonium and urea versus nitrate, impact plant physiology and water requirements, growers can navigate a transition to a system where soil biology provides the majority of the crop's nutritional needs . In this webinar, John discusses: High-yielding crops historically receive about 80% of their nitrogen as ammonium and 20% as nitrate . Plants and soil biology interact with specific nitrogen forms like amino acids rather than generic N . Nitrate requires three molecules of water for conversion, increasing a plant's total water requirement . Foliar urea can be four to seven times more efficient than soil-applied nitrogen Replacing the first 25 pounds of nitrogen with 25 pounds of sulfur can deliver an equivalent yield responses Managing nitrogen with carbon and molybdenum reduces leaching and supports biological fixation Additional Resources To learn more about the Minnesota Soil Health Coalition, please visit: https://www.mnsoilhealth.org/ To learn more about AEA's approach to Nitrogen Management, please visit: https://advancingecoag.com/article/regenerative-nitrogen/ About John Kempf John Kempf is the founder of Advancing Eco Agriculture (AEA).

S8 Ep 8Episode 175: Wild-Range Metabolomics and Nutrient Density with Glenn Elzinga
Glenn Elzinga is a seasoned rancher who has spent 34 years managing Alderspring Ranch in the wild, high-country landscapes of Idaho. Growing up on conventional farms that relied heavily on chemicals and formulaic business models, Glenn's career shifted dramatically after a "clobber over the head" moment forced him to innovate to survive. Today, he and his family manage 47,000 acres of wilderness rangeland, where they have pioneered "inheritance grazing" by living with their cattle 24-7 on horseback to coexist with wolves and maximize plant diversity. By collaborating with researchers like Dr. Stephan van Vliet, he has provided empirical evidence that grazing cattle on diverse wild ranges produces beef with significantly higher anti-inflammatory and antioxidant compounds compared to feedlot alternatives. His work emphasizes the "nutritional wisdom" of animals and the importance of vertical enterprise stacking to create a profitable, multi-generational future for regenerative agriculture. In this episode, John and Glenn discuss: The shift from formulaic commodity agriculture to the "Wild West" of the regenerative space. How maintaining human presence on the ground allows ranchers to coexist with predators like wolves. The results of metabolomics research comparing wild-range beef to feedlot beef. The concept of nutritional wisdom and how cattle self-select plants for preventative medicine. Why handling cattle with a focus on their left-eye perception reduces stress and improves performance. Moving from horizontal expansion to vertical stacking to bring the next generation into agriculture.
