Tailgate | Holistic Soil Health

Building healthy soils is key to resilient vineyards—but how do you measure success, and which practices truly move the needle?

Join us for an in-field discussion exploring soil health from multiple angles, starting with three presentations:

• Jenny Garley (Bio SI) will share insights on using sap sugar levels as a practical indicator of plant and soil health, highlighting how increased microbial activity (especially fungi) can boost photosynthesis and overall vineyard performance.
   
• Dr. Stewart Wilson (Cal Poly) will provide a soil science perspective, grounding the conversation in the latest research and field applications.
   
• Mike Costello (Oakville Bluegrass) will outline current funding and grant opportunities available to growers, with a focus on cover crops and soil-building practices.

We’ll then transition to a grower panel led by host Bob Tillman, sharing real-world experience implementing regenerative practices. Panel participants:

• John Howell, Booker Wines 

• Jordan Lonborg, Coastal Vineyard Care Associates

• Bob Tillman, Alta Colina 

• Steve Vierra, Derby Wine Estates 

Come ready to dig into practical tools, emerging insights, and peer-driven strategies for improving soil health in your vineyard!
