    Episode 177: Leveraging Native Biology and No-Till Strategies with Bob Tillman

    04/16/2026 | 1h
    Bob Tillman is a former electronics professional who launched Alta Colina Vineyard & Winery in 2003 on the steep, mountainous terrain of Paso Robles, California . Managing thirty-two acres of grapes, he has spent two decades transitioning from conventional methods to a biological approach centered on the natural resilience of his native ecosystem.
    He eliminated tillage in 2006 and moved away from synthetic inputs to rely on native ground cover and biological cycling . By utilizing total nutrition testing, he identifies vast mineral reserves already present in his soil and focuses on microbial health to make those nutrients available to the vines

    In this episode, John and Bob discuss:

    Tranisitiong to a completely no-till system after observing that native grasses were more effective and resilient than planted cover crops .

    How nutrition testing revealed that the soil contains enough potassium for over six hundred years and enough iron for millions of years of production .

    Utilizing AEA and sap analysis to identify specific micronutrient deficiencies and adjust nutrition throughout the growing season through foliar applications.

    Applying AEA products like CalGuard and Rebound Boron helps address seasonal trending deficiencies in calcium and boron levels .

    How the vineyard uses compost extracts and teas to inject biological activity directly into the soil through the irrigation system .

    High-density native plant populations providing ground cover that supports deep-rooted vines while maintaining high soil organic matter .

    Episode 176: Vertical Integration for Regenerative Farmers with David Stelzer

    04/09/2026 | 1h 12 mins.
    David Stelzer is the founder of Azure Standard, a company born from a 1970s family health crisis that inspired a switch to organic farming. When a major processor dropped their organic grain for conventional wheat in the 1980s, David began delivering his own crops directly to co-ops in a pickup truck. This grew into a massive independent distribution network that now manages roughly 12,000 SKUs, connecting growers directly to consumers.
    In the field of regenerative agriculture, David focuses on vertical integration to bypass the expensive and often unethical mainstream middleman. By managing the farming, processing, and distribution in-house, he is able to pay farmers higher premiums while keeping food affordable for families. On his 5,000-acre farm, he proves that regenerative systems can match conventional yields while producing nutritionally superior food.
    In this episode, John and David discuss:
    David's childhood recovery from a life-threatening respiratory illness after his parents transitioned the family to a whole-food, organic diet.

    The decision to stop using mercury-treated seeds after realizing the chemical was intended for a disease that didn't exist in their region.

    How the loss of a major organic grain contract forced David to start his own distribution route, which eventually grew into Azure Standard.

    The vertical integration model that removes middlemen and brokers to pay farmers more while keeping consumer prices competitive.

    David's observation that their 5,000-acre organic farm maintains yields comparable to conventional neighbors without long-term losses.

    The astronomical demand for domestic organic and regenerative products, including frozen fruits and legumes, which currently outpaces US supply.

    Podcast Extra: Adjusting Nitrogen Management with John Kempf and MSHC

    04/02/2026 | 1h
    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

    Episode 175: Wild-Range Metabolomics and Nutrient Density with Glenn Elzinga

    03/26/2026 | 1h 41 mins.
    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.

    Episode 174: Scaling Regenerative Practices from Micro-Farms to Row Crops with Briana Bosch

    03/19/2026 | 1h 16 mins.
    Briana Bosch is the founder of Blossom and Branch, where she manages a two-acre flower micro-farm in Denver and a 180-acre family grain farm in Minnesota. With a background in journalism and a master's in marketing, she has become a prominent voice in the regenerative movement by focusing on scaling soil health concepts for both small-scale market gardens and large-scale commodity operations. 
    Last year marked a significant milestone in her transition of the family's century-old Minnesota farm, as she implemented intensive regenerative practices for the first time, including the total elimination of herbicides and fungicides on her experimental acreage. 

    In this episode, John and Briana discuss: 

    The role of authenticity and maintaining the "true voice" to build lasting trust


    Her transition from using plastic mulch and netting to implementing living ground covers and high-carbon mulches like wood chips


    How flower production can net a higher profit per acre than almost any other crop, including marijuana, when focused on local markets


    The benefits of 60-inch corn rows for facilitating intercropping and cover crop growth within the constraints of a short northern growing season


    Seed inoculation as the most effective "low-hanging fruit" for jump-starting soil biology and reducing synthetic fertilizer needs


    The psychological and cultural barriers, such as "groupthink" and defensiveness, that often prevent farmers from adopting new practices
