Episode 162: Increasing Pecan Yields up to 6x While Eliminating Herbicides with Troy Swift
Troy Swift started farming at age 42, and has achieved incredible results using regenerative practices in his Texas pecan grove: increasing yields in certain varieties by up to 6X, while cutting nitrogen inputs by 97%, reducing insecticides, and eliminating herbicides. Troy is a first-generation farmer from Central Texas who transitioned to pecan farming after a career in the composite jet engine industry. With a data-driven mindset from his manufacturing background, he now manages 126 acres of hybrid and native pecans along the San Marcos River and serves as president of the Texas Pecan Growers Association. Troy’s 27 years of growing experience shape his innovative approach to regenerative agriculture. Since 2019, Troy has embraced regenerative practices: eliminating mowing and herbicides, and using wood chips and Johnson-Su bioreactors to boost soil health. His orchard serves as a research hub for institutions like the Noble Research Institute, providing data on soil, nut nutrition, and economics. Troy’s work inspires farmers and bridges the gap between academia and agriculture. In this episode, John and Troy discuss: Troy’s transition from the composite jet engine industry to becoming a first-generation pecan farmer Shifting to regenerative practices, including eliminating mowing Reducing nitrogen inputs from 80-100 pounds per acre to just 2.4 pounds Using bats for pest control and their impact on reducing insecticide use in pecan orchards The importance of data-driven farming, with insights from soil and leaf analyses showing increased nutrient availability Troy’s leadership in fostering collaboration between farmers and academia to advance regenerative agriculture research Additional Resources To learn more about Troy and to purchase Swift River Pecans, please visit: https://www.swiftriverpecans.com/ About John Kempf John Kempf is the founder of Advancing Eco Agriculture (AEA).

Episode 161: Increasing Corn Yields with Fewer Inputs with Jake Ewing
Jake Ewing farms 1,300 acres of corn in Western Illinois, a relatively small operation compared to neighboring farms. Jake’s farm has been shaped by the need to compete in a region dominated by large-scale commodity crop production, forcing him to rethink traditional approaches to corn farming, and developing a focus on innovative, cost-effective practices. Jake’s journey toward regenerative agriculture began with the purchase of a high-clearance sprayer, initially intended for conventional applications. This led to experiments with foliar fertilizers and reductions in herbicides and fungicides. His focus on soil health and plant nutrition has boosted yields to 275-285 bushels per acre, surpassing county averages while lowering costs. In this episode, John and Jake discuss: Reducing nitrogen applications to 160 pounds per acre, with only 100 pounds soil-applied, using foliar urea for efficiency. Foliar applications of manganese, copper, and cobalt to improve plant health and delay senescence, increasing yields. How foliar sprays in the evening with larger droplets enhance nutrient absorption by keeping solutions liquid longer. Eliminating insecticides and cutting fungicide use to a half-rate single pass, aiming for total elimination. How adequate manganese, copper, and zinc levels in sap tests reduce disease pressure, minimizing fungicide needs. About John Kempf John Kempf is the founder of Advancing Eco Agriculture (AEA).

Episode 159: Preserving Family Farms Through Effective Communication with Vance Crowe
Vance Crowe believes that the key to preserving multi-generational farms is for farmers to communicate better, especially within their own families. As founder of Legacy Interviews, podcast host, and keynote speaker, Vance knows a thing or two about communication. Vance developed strong communication skills early on, shaped by a competitive family environment on an Illinois farm. Vance has worked as a deckhand, in the Peace Corps in Africa, and for five years as Monsanto’s Director of Millennial Engagement. He now runs Legacy Interviews, which preserves family histories, and is recognized for his articulate communication style. In this episode, Vance and John discuss: Vance’s path from Illinois to Monsanto and Legacy Interviews Farmers’ need to communicate family values and knowledge Society’s disconnect from agriculture and farmers’ marketing potential AI’s role in enhancing human contributions in agriculture Preserving generational wisdom through storytelling The value of direct communication and constructive disagreement Additional Resources To learn more about the Vance and his work, please visit: https://www.vancecrowe.com/ About John Kempf John Kempf is the founder of Advancing Eco Agriculture (AEA).

Podcast Extra: Field Talks with John Kempf and Cole Neese
Join AEA founder John Kempf for Field Talks, a series of in-the-field conversations. This episode features Cole Neese, a corn and soybean grower in Indiana. Together, they explore real-time agronomic insights, crop progress, challenges, and success stories from the growing season. In this episode, John and Cole Neese, a farmer from West Central Indiana, discuss: Excessive Rainfall Challenges: Cole faced persistent wet conditions, saturating soils and delaying corn and soybean emergence. Success with Accelerate on Soybeans: Applying Accelerate at R2 increased soybean pod counts by 50-80%, though drought later limited yields. BioCoat Gold in Stressed Conditions: BioCoat Gold significantly improved corn performance in a late-planted, highly stressed field with low yields, likely due to enhanced mycorrhizae activity. Improved Soybean Pod Integrity: Regenerative soybeans showed stronger pods, resisting shattering during harvest, likely due to enhanced cobalt and copper levels.
