Pre-Conference Tour

The conference started off with a tour at California Polytechnic State University, San Luis Obispo (Cal Poly SLO), the afternoon of October 26, 2021. During the tour, attendees had the opportunity to learn about ongoing research and activities at Cal Poly’s Strawberry Center and Organic Farm. Attendees also had the chance to see Cal Poly’s new Justin and J. Lohr Center for Wine and Viticulture with a newly established bio-digester system.
