RCD staff can evaluate and improve the precision of your irrigation protocols in the vineyard.

Save Water, Save Money, Maximize Quality

The best irrigation schedule has a triple bottom line: efficient use of water, sensible use of labor and maximum quality of fruit.

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:

  1. Maximize grape quality
  2. Optimize grape yields
  3. Minimize operational costs and improve labor efficiency
  4. Reduce disease risks to your crop

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).

The Irrigation Toolbox

The full-scale Irrigation Toolbox is a new service that will be offered to five growers to help them with consultation, tools and technologies to holistically evaluate and improve irrigation volume and timing.

This is for growers who want to upgrade their overall irrigation system. We’re seeking vineyards with irrigation issues and growers who want assistance with scheduling and haven’t yet pursued precision irrigation. This could be soil analysis, implementing both mainstream and cutting-edge technologies and/or addressing water quality issues.

The Irrigation Toolbox is customized and RCD staff will work with each grower for two full irrigation seasons to help with ongoing monitoring and use of the equipment. The RCD will release a request for applications in April. Please note there is a cost-share component.

The Mobile Irrigation Lab

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.

The grower always gets something out of the evaluation. DU evaluations often aren’t on the top of the vineyard manager’s to do list, and can be overlooked. But if the DU rating is low, the field isn’t being irrigated uniformly, usually due to low-pressure or clogged emitters. We often identify quick adjustments like filter cleaning or injecting a drip cleaner a few times a year to break down and dissolve blockages.

Schembre has worked with small growers and large vineyard management companies to develop custom protocols. This includes Renteria Vineyard Management, which manages several Napa Green Land sites. The evaluation can be particularly helpful for those managing multiple vineyards over broad areas.

Working closely with the Napa RCD and developing custom drip uniformity protocols has enabled Renteria Vineyard Management to accurately and efficiently irrigate specifically designed precision farming zones with confidence. With these capabilities, we’ve increased yields and quality.

One of the main resistances to phasing out glyphosate is increased labor and equipment costs. However, the costs of herbicides and fertilizers have risen dramatically, so increased labor demands can be offset by reduced supply chain purchases. 

In addition, leaders like Grgich Hills Estate have shown that regenerative organic farming can be cost-effective. According to an analysis by Brotemarkle Davis & Co. LLP accounting firm, the average annual per acre cost of vineyard management in the Napa Valley is $14,800, with $3,800 in depreciation. At Grgich, they spend $11,000 per acre, with only $1,300 in depreciation due to the longer life of their vineyards. 

Learn from regional leaders about the practical costs, benefits, and ROI of herbicide-free, organic, and regenerative vineyard management.

Join us for a special roundtable workshop with award-winning journalist Elin McCoy, global wine critic for Bloomberg News and US editor for the podcast The Wine Conversation, with listeners in 95 countries. 

Elin will sit down with a small group of Napa Green members (max 25 guests) and share her insights on the types of stories and pitches most likely to engage the media. In particular, she’ll focus on stories related to sustainable winegrowing, climate action, and social equity. 

Elin will speak and answer questions for about an hour. Then we’ll break into small groups to develop a story pitch, and come back together to present and get Elin’s feedback and input. This is a rare opportunity to get ideas and inspiration from a leading wine journalist. Register at the link in our profile.

One of the most critical agricultural concerns with our changing climate, and more frequent & intense weather extremes, is precipitation and water availability. The good news is opportunities abound to optimize irrigation efficiency, and implement regenerative practices that improve soil health, water infiltration, and retention. 

Join us for The Future of Water, with highlights including a keynote from Peter Gleick, one of the world’s leading water experts, and Mimi Casteel, not only a viticulturist and winemaker, but also a forest ecologist with a vision for water resiliency.

Join us for The Future of Water Workshop, to explore our water future, with highlights including a keynote from Peter Gleick, one of the world’s leading water experts (all guests will receive a copy of Peter’s most recent book, The Three Ages of Water) and Mimi Casteel, not only a viticulturist and winemaker, but also a forest ecologist with a vision for water resiliency.

Wine grape quality is closely tied to the right amount of water, at the right time. One of the most critical agricultural concerns with our changing climate, and more frequent & intense weather extremes, is precipitation and water availability. We’ve swung from historic drought to atmospheric rivers. Our community has huge swaths of unmanaged, unhealthy forests full of non-natives and overrun by firs, amplifying fire risk and undermining one of the most critical systems for groundwater recharge.

The good news is opportunities abound to optimize irrigation efficiency, and implement regenerative practices that improve soil health, water infiltration, and retention. A watershed coalition has also formed in Napa County to pilot and model creek & forest restoration for localized water resiliency and climate cooling. 

Come learn more on Thursday, May 23rd at 9:00am at @silveroakcellars.
