Episode #83: John Warmerdam
05/09/23 • 82 min
John Warmerdam is a third-generation stone fruit grower in the San Joaquin Valley of California. His grandfather came to the area from Holland in 1911 and started a small farming operation that John’s father, John N. Warmerdam, eventually took over. Today John and his dad farm over 350 acres of peaches, plums, nectarines, kiwi, and almonds. The Warmerdams also have one of the largest cherry-growing operations in the southern San Joaquin Valley and have been innovators in the fruit packing industry for 45 years. In this episode, they discuss:
- Cultural management practices for stone fruit
- Transitions in his farming systems
- Mite management
- Driving factors for considering regenerative management
- Pruning and thinning management
- Future water usage issues
- Generational shifts in farming
Additional Resources: Concepts for Understanding Fruit Trees by Theodore DeJong

Episode #82: Dr. Erin Silva
Dr. Erin Silva is an Associate Professor and State Extension Specialist in Organic and Sustainable Cropping Systems in the Department of Plant Pathology as well as the Director for the Center for Integrated Agricultural Systems in the College of Agricultural and Life Sciences at UW-Madison.
After completing a Ph.D. in Horticulture at Washington State University, Dr. Silva obtained a faculty position at New Mexico State University. During her tenure at NMSU, Dr. Silva taught courses on organic vegetable production, including an experiential learning course integrating the campus working student organic Community Supported Agriculture (CSA) farm. Dr. Silva initiated several organic research projects at NMSU, including work on a cover crop-based reduced tillage approach for organic vegetable crops and breeding vegetables for organic production systems.
These research themes continued as Dr. Silva moved into the first organically focused research position at the UW-Madison College of Agricultural and Life Sciences in 2006. Through her work at UW-Madison, she has developed an internationally recognized program that improves the management of organic production systems and increases the profitability and sustainability for organic producers and rural communities.
In this episode, Dr. Silva and John discuss the following:
