CARBON FARMING OVERVIEW
Marin RCD’s Carbon Farming Program
In our Carbon Farming Program, the Marin RCD provides farmers and ranchers with financial and technical assistance for the planning, design, and implementation of carbon beneficial practices.
Since 2008, Marin RCD has been directly involved in carbon sequestration research, planning, and implementation as a partner in the Marin Carbon Project. The Marin Carbon Project – a partnership of local agricultural, conservation, and County organizations – seeks to assist landowners and land managers in serving as stewards of soil health and undertaking carbon farming in a manner that can improve on-farm productivity and viability, enhance ecosystem functions, and stop and reverse climate change.
As of 2020, Marin RCD and partners in the Marin Carbon Project have completed 19 Carbon Farm Plans. Presently, Marin RCD is writing one new plan and has a waitlist of 68 producers interested in receiving one! Contact us if you would like to be added to our list.

On December 2020, the Marin Board of Supervisors adopted an updated Climate Action Plan that outlines how the County will mitigate and adapt to climate change and sets targets and measures for 2030. As noted on page 46 of the plan: “the agricultural sector can reduce emissions from production, sequester carbon and build soil carbon stocks, and play a role in cross-sectoral efforts to enhance the ecological benefits to natural lands.”
All to say, Carbon Farming is and can be part of the solution to meeting our local climate adaptation and mitigation goals! Read more here.
What is Carbon Farming?
Plants “breathe” in atmospheric carbon and convert it into sugar so they can grow, through the process of photosynthesis. Plants transport some carbon, in sugar form, to their roots to trade fungi for minerals or to store for a later time when the need food. When the carbon gets to the soil, it interacts with the soil ecosystem and a variety of things can happen. Depending on how the plant and soil is managed (or not), the carbon can remain in the soil for long-periods of time in a stable state—that is, become sequestered within the soil. The phrase ‘carbon farming’ means implementing farming practices that capture and hold carbon in vegetation and soils and/or reduce greenhouse gas emissions. Carbon farming includes simple to technologically-advanced practices – like not tilling the soil, planting a cover crop, prescribed grazing, to installing an anaerobic methane digester. Carbon Farming practices can also lead to improvements in soil health, water holding capacity, crop and forage productivity, water conservation, on-farm habitat, biodiversity, and climate resiliency.

Soil Organic Carbon
The cycling of the element, carbon, is fundamental to life on earth. One main phase of the carbon cycle is when carbon is stored in soil. ‘Soil organic carbon’ (SOC) – the amount of carbon stored in the soil – is a component of soil organic matter and is the basis of soil fertility. SOC releases nutrients for plant growth, promotes the structure, biological and physical health of soil, and is a buffer against harmful substances. A 1% increase in soil organic matter – a majority of which is carbon – will hold 20,000 gallons more water per acre!
What is Carbon Farm Planning?
Carbon Farm Planning combines traditional whole-farm planning and natural resource assessment with up-to-date climate science to identify practices that a land steward can implement to increase carbon sequestration and reduce greenhouse gas emissions on the farm. Marin RCD and our partners work with land stewards to create site-specific Carbon Farm Plans that prescribe applicable NRCS Conservation Practices. Climate benefits of implementing the proposed practices are then quantified using GHG planning and modeling tools including COMET Planner and COMET Farm.
Once completed, Carbon Farm Plans can serve as a foundation from which Marin RCD and our partners can work with a land steward to provide financial and technical assistance for the design and implementation phases. Carbon Farm Plans may also be living documents that are updated as land-bases change hands, a producer’s goals shift, or practices are implemented and new opportunities arise.
Carbon Farm Plan templates are available for rangelands, vineyards, orchards and forests on the carbon farming webpages of the North Bay RCDs, linked below:

Frequently Asked Questions (FAQ’s):
Are Marin RCD and Marin Carbon Project the same thing?
- No. Marin RCD is only one of the many partners that make up the collective known as the Marin Carbon Project. Other partners in the collective include: Carbon Cycle Institute, Marin Agricultural Land Trust, Marin County, Marin County Agricultural Commissioner, Marin Organic (past member), Marin UC Cooperative Extension, University of California at Berkeley, Silver Labs, USDA Natural Resources Conservation Service (NRCS), and John Wick of Nicasio Native Grass Ranch. Marin Carbon Project does not have any staff. Visit the Marin Carbon Project website to learn more.
How can I get on your waitlist if I am interested in receiving a Carbon Farm Plan?
- Please fill out our contact form, send an email to firstname.lastname@example.org, or call us at 415-663-1170. Note: to be eligible to work with Marin RCD to receive a Carbon Farm Plan, your land must be in Marin County and must be in agricultural production.
How are farms selected to receive a Carbon Farm Plan from Marin RCD?
- When Marin RCD is awarded funding to write carbon farm plans, either past ranking lists are consulted, or Marin RCD will run a new solicitation round. If running a new round, all agriculturally zoned parcels in Marin County will be sent a solicitation notice asking if they want to apply to receive a Carbon Farm Plan. Those on the Carbon Farm Plan waitlist will also be notified by email or other means.
- Interested farms will be visited by a Technical Advisory Committee who will rank the farm against a selection criteria. Among other things, the selection criteria scores for the potential GHG sequestration potential of the farm, co-benefits including wildlife habitat and hydrologic improvements, and the landowner’s commitment to the planning and implementation process.
- The highest ranking farms will be selected to receive a Carbon Farm Plan.

What about the North Coast Soil Health Hub?
The North Coast Soil Health Hub is an agricultural network comprised of 7 Resource Conservation Districts – Gold Ridge, Humboldt, Lake, Marin, Mendocino, Napa, and Sonoma – as well as producers and partners in the region. In order to increase farm resiliency and steward the land for future generations, the Soil Hub works to identify the co-benefits of improved soil health in soils and agriculture specific to the North Coast. The Soil Hub aims to further the understanding of unique opportunities and challenges of soils in the region, and advance soil health practices and carbon farm planning through providing education and technical assistance to producers, sharing resources among RCDs, and harnessing collective fundraising power.
The Soil Hub was founded in 2017 and spent its first four years serving the vineyard community in Mendocino, Napa, and Sonoma Counties and partnering with wine grape growers, industry representatives, scientists, and agricultural professionals. The Soil Hub has established demonstration sites to model implementation of soil health practices, conducted field trials, assisted producers with soil health assessments, developed custom Carbon Farm Plans for producers, and hosted an annual Soil Symposium.
Now, the Soil Hub is leveraging its successes working with wine grape growers and expanding its network to encompass other production systems including range, dairy, orchards, and row crops. In addition to serving new land uses, the Soil Hub is expanding geographically to include Humboldt, Lake, and Marin Counties. The Soil Hub believes more can be accomplished when working together, and aims to meet the needs of producers in the region and support the incorporation of agriculture into local policy and planning initiatives.
Through a grant from the National Association of Conservation Districts, Marin RCD hosts the Regional Coordinator for the North Coast Soil Health Hub. Stay tuned to find out what is next at the Soil Hub, and feel free to reach out to Emilie Winfield at email@example.com with any questions.
Various funding programs can provide cost-share, incentive, or full funding for conservation and carbon farming projects in Marin.
At times, Marin RCD is awarded private or public funds to administer for the design and implementation of Carbon Farm Plan practices on private working lands in Marin County. If you have questions about current funding opportunities through Marin RCD, we recommend that you call us at 415-663-1170, email us at firstname.lastname@example.org, or fill out the form below.
