This page provides links to the Sonoma County Vineyard Water Conservation Demonstration Project. The project is being conducted by the Sonoma County Water Agency. Mark Greenspan is coordinating the project for the agency. The demonstration site is at Hoot Owl Creek Vineyards / Alexander Valley Vineyards and will be showcasing various irrigation strategies side-by-side, as well as a low-volume approach to vineyard cooling during high heat events. All data collected in this project will be made available, including vineyard plant moisture status, soil moisture of 6 irrigation practices, a soil moisture wetting profile, measured by soil moisture devices, and weather data. The irrigation and cooling systems will be automated and irrigation and cooling events will be visible.
The Final Report for the 2009 demonstratino project is now available, demonstrating quite substantial water savings in irrigation and cooling! Please note that the results of this demonstration project represent one season's practice at one particular site. Nevertheless, the concepts discussed may be applied to any vineyard in this region and to many other regions as well.
