Leading With Purpose: California Walnut Board and Commission Kicks Off Virtual Sustainability Series
The California Walnut Board and Commission are taking focused, meaningful steps to support the long-term success of California’s walnut industry. One of its latest efforts: launching the new Virtual Sustainability Series to provide practical, science-based solutions for growers, handlers, and processors across the state.
The series debuted on May 14, 2025 with a session focused on Soil Health. From nutrient management to cover cropping, the session delivered actionable insights that growers can apply regardless of where they are in their sustainability journey. This is part of the Board and Commission’s broader commitment to ensure that no member of the industry is left behind as the industry advances toward a more resilient, sustainable future.
More Than a Webinar Series
The Virtual Sustainability Series is part of a coordinated, long-term strategy to invest in the education, tools, and support systems walnut producers need to adapt and thrive. It aligns with the Board and Commission’s broader sustainability framework, organized around four priority areas:
Sustainable Pest Management/IPM
Soil Health
Water Management
Greenhouse Gas Emissions and Carbon Sequestration

Session 1 Recap: Soil Health
The first session emphasized the essential role of biological processes and adaptive practices in modern walnut production.
Deac Jones of Andaman Ag presented on biological nutrient management, underscoring the importance of supporting soil microbiology to strengthen plant health. Rather than relying solely on chemical inputs, he emphasized working with natural systems, such as fungi and mycorrhizae, to build plant resilience and productivity.
“Farming is more about biology than chemistry. We must farm in ways that allow nature to work with us.” — Deac Jones
Tom Johnson from Project Apis m. focused on cover cropping in walnut orchards, describing soil health as a living system that depends on consistency over time. He detailed how cover crops contribute to water infiltration, nutrient cycling, and natural pest suppression—and why sustained practice is critical for long-term benefits.
“You can skip one season, but not two. Soil health takes consistency to pay off.” — Tom Johnson
Collective Leadership, Industry-Driven Impact
The California Walnut Board and Commission’s leadership is clear, not just in launching this series, but in creating the structure and space for meaningful learning and industry advancement. Through these efforts, they are providing the foundation for a stronger, more sustainable walnut industry that supports both current and future generations of farmers.
Measure to Improve is honored to help facilitate this series. But the vision, direction, and outcomes belong to the Board, the Commission, and the broader walnut industry as they work to advance practical sustainability while preserving the environment.
The next session, focused on Water Management, is scheduled for June 25 at 1:00 p.m. To request access to the webinar recording or learn more about upcoming sessions, contact the California Walnut Board at resources@walnuts.org
