Fair Play, California is located in the Sierra Foothills at an elevation of 2,000 to 2,800 feet. Although wine grape production has flourished in the region, Fair Play has a limited water supply. No irrigation district delivers water, and no one is certain how much groundwater there actually is. As a result, the vineyard managers in Fair Play are looking for a way to increase the efficiency of their water applications. They would like to gather data on the following:
- How, where, and when the grapevines extract water from the soil
- What the root distribution of the grapevines is
- Whether the use of water depends on the slope
- How much water cover crops use
- How effective drip irrigation is
- From what depths the grapevines extract water late in the season
With the help of a Western SARE Farmer/Rancher research grant, these California vintners are working to answer these questions.
To begin the experiment, they will set up soil moisture probe sites. A group of Fair Play vintners have committed to using a soil moisture monitoring service, which will measure soil moisture at each foot. Using this service, they will collect data throughout the season and then apply this data to answer the questions listed above. For part of the experiment, they will backhoe trenches along the grapevines and collect root distribution data. The results of this experiment will be shared with other vintners through winery and grape growers associations. Through this experiment, the vintners of Fair Play hope to conserve their limited water resources and make their vineyards more sustainable.
