Russell Ranch Field Day 2010

The 2010 Field Day at Russell Ranch Sustainable Agriculture Facility took place on Tuesday, June 22.

Tim Hartz Presentation

This year, the day began with remarks from ASI Director Tom Tomich, who provided an overview of Russell Ranch and ASI.

Next up was a field tour, where Cooperative Extension specialists, UC Davis faculty, post-docs and graduate students presented results from their current research projects.

The day wrapped up with the grower panel – a discussion on the pros and cons of drip tape, with participation from farmers John Meek (JH Meek and Sons), Rick Martinez (Davis), and Scott Park (Park Farming Organics).

For a run-down on the grower panel, read this blog post.
