  • Episode 177: Leveraging Native Biology and No-Till Strategies with Bob Tillman
    Apr 16 2026
    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
    Apr 9 2026

    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
    Apr 2 2026
    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).
