Darek Trowbridge, Owner, Old World Winery & Soil Carbon Management Company

In 2012 Darek started making a Regenerative Composted Mulch for use in his Biodynamic and Regenerative farming and to help revive 120 year old vines that his great Grandfather once tended. From that success he has brought this material to 6 other ranches that are now farmed by Darek regeneratively. In addition, Darek grows food crops and eggs on a small market garden using the Regenerative Composted Mulch. This has provided sustenance for many customers, friends and family and acts like a demonstration project for visitors to see how to grow crops without (soil organic matter destroying) tillage using Darek’s soil amendment.

We believe that there are a number of groups and organizations throughout the County that would be interested in hosting speakers on topics relevant to the LTF and the Zero Waste Sonoma. This could include organizations and groups providing speakers but also having their own topics of interest that they would like to know more about. Examples might include:

  • Lion’s Club
  • Rotary Clubs
  • Democratic Club
  • Local businesses associations
  • Chambers of Commerce
  • Young professional groups
  • Committee for Change (Windsor High School students)
  • HOAs
  • School groups

Do you have an idea for a speaker you think should be added to this list?

Please mark whether this is a new suggestion or update to an existing speaker/organization listed above.
