Agricultural Burning

NVG’s Low-Smoke Agricultural Burning Program

Often there is no one right answer to any sustainable best practices question, but as responsible farmers, we pursue practices that complement and protect our unique environment and natural resources and work proactively to find sustainable solutions. NVG’s innovative technique is gaining momentum as a farmer designed and driven, sustainable, just, and economical alternative to traditional ag burning.

NVG's Vineyard Burning Task Force developed a 6-step approach to help preserve air quality by significantly reducing the amount of smoke generated in Napa County due to agricultural burns. The technique promotes:

Effective vine-pulling procedure
Proper vine drying times
Removal of excess dirt
Tarping to keep the center of the piles dry during rain events

The result is a virtually smoke-free burn—known as ‘NVG’s Low-Smoke Agricultural Burning Program’. Click on the English and Spanish brochures below for details. Hard copies are available to for members at the NVG office.

The Importance of Burning for Mitigating Pest & Disease Pressures

Burning is an essential practice with no known alternative when it comes to mitigating risks associated with pest and disease issues. Most invasive pests are vectored by moving vine material, including chipped and woody debris. In such instances, other alternative methods such as chipping and grinding cannot be implemented.

Serious economic repercussions can result from the spread of detrimental pests and diseases. Efforts recently taken to eradicate the European Grapevine Moth (EGVM) mandated federal and state permits, inspections, quarantine zones, and strict restrictions on movement of all grapevine plant material—at the cost of $115 million in public and private funds. The issue is as much about the pests and diseases we don’t know, as the ones we do. Future vineyard pests could pose a similar threat. As such, grapevine woody debris is best disposed of on-site and through disease eliminative processes such as burning. NVG's program could also be expanded to help mitigate risk associated with the loss of other crops grown in California.

NVG's Vineyard Burning Task Force

In November 2015, NVG convened a ‘Vineyard Burning Task Force’ to address concerns over the occurrences of smoky burns in Napa Valley. The Vineyard Burning Task Force is comprised of growers, leaders in local sustainable practices, and experts in fire science. A commitment was made to develop a 3-year plan to reduce smoke and preserve air quality in Napa Valley. Since 2018, NVG continues to expand its educational outreach providing seminars and resources to the ag community in both Spanish and English.

Task Force Work & Results

By educating the broader community on the low-smoke burning technique, we can:

Lessen the carbon footprint and negative health impacts that result from traditional smoky burns
Provide an environmentally friendly alternative technique for growers to mitigate serious pest and disease issues

Achievements include:

Development of new vine removal protocol and best practices brochure in English and Spanish
New, improved 'Open Burning Best Practices' white paper
Field days with live burn demonstrations
Annual ROOTSTOCK Symposium informational session
Partnering with Napa Sierra Club and Napa Climate NOW! to pursue future research opportunities
Representation and community education through public forums
Preventative outreach to high-risk sites--the NVG Task Force proactively reaches out to properties with high risk burn piles
Program listed on Napa County Agricultural Commissioner's website

No other agricultural region has instituted a program such as this one. However, we believe that at minimum additional cost, it could be implemented in other wine regions and for other orchard crops across California.

Thank you to the NVG Task Force!
