RCD staff can evaluate and improve the precision of your irrigation protocols in the vineyard.
Efficient, targeted irrigation benefits both your bottom line and the quality of your fruit, ensuring vines get the right amount of water at the right time. Here are the benefits of irrigation efficiency:
The Napa County Resource Conservation District (RCD) received grant funding to assist growers with low- to no-cost services that improve vineyard irrigation efficiency and scheduling. These include a comprehensive “Irrigation Toolbox” and the “Mobile Irrigation Lab” (a core component of the Toolbox).
Any grower can request the Mobile Irrigation Lab. The Lab provides rapid evaluation of irrigation efficiency and uniformity throughout the vineyard. It identifies ways to improve water use and irrigation system performance, which improves vine health. The evaluations focus on Distribution Uniformity (DU) – how evenly the irrigation system is delivering water throughout the vineyard block.
The assessments require the grower to run a normal irrigation set on a standard irrigation area where the grower has some concern or wants to gain additional information for that vineyard. Each grower will commit to participating in the evaluation (2-4 hours), which is considered the “cost share” component.
