S2:E8 – A Million Acres and 35 Million Pounds of Seed: The Story of Green Cover and the Economics of Cover Crops, with Keith Berns

Early regenerative pioneer Keith Berns, co-founder of Green Cover, recounts how multi-species cover crops transformed from niche experiment to a million-acre business. 

Green Cover is a cover-crop innovator and one of the country’s leading cover crop seed suppliers. In this conversation, we talk with Keith about:

• Science and Practice: He discusses the limits of single-variable academic research in inherently complex, multi-species systems, the specific cases where single-species cover crops still make sense, and strategies in areas of limited moisture where cultivation may be more challenging.
• Economic and Policy Factors: Keith breaks down the direct economic benefits of cover crops (including livestock integration, fertility gains, weed suppression, and improved water infiltration) that compound into long-term resilience as soil organic matter builds. He also explains how federal crop-insurance rules, particularly “Annual Production History,” continue to restrict both producer adoption and seed production.
• Signals of Demand: Keith talks about the indicators he’s watching to gauge future adoption, why incentive programs alone aren’t enough to drive meaningful growth, and how he’s managing the challenges of scaling in a maturing market.
• Data and Decision-Making: He highlights the largest data gap he sees in the industry—where empirical evidence still lags behind what farmers observe in the field—and shares what growers are managing day-to-day: economic pressures, agronomic trade-offs, and practical constraints like planting windows.

We hope you enjoy this grounded, data-aware conversation about the pivotal yet still-evolving role cover crops play in regenerative agriculture and soil health.
