The Reserve is developing a Soil Enrichment Protocol (SEP) that will provide guidance on how to quantify, monitor, report, and verify agricultural practices that enhance carbon storage in soils. The primary GHG benefit targeted will be the accrual of additional carbon in agricultural soils, with hopes to incentivize GHG emission reductions from other sources, such as N2O from fertilizer use.
Protocol development is funded by Indigo Ag.
The most recent draft of the protocol is available for public review below. The protocol will be presented to the Reserve Board of Directors on September 30, 2020.
- Soil Enrichment Protocol Version 1.0 – Draft for Board Approval (September 16, 2020)
- Soil Enrichment Protocol Version 1.0 – Redline from August Draft to Board Draft (coming soon)

The Soil Enrichment Protocol is being developed through the Reserve’s multi-stakeholder workgroup process. The Reserve strives to create a well-balanced workgroup consisting of industry representatives, project developers, farmers, environmental NGOs, verification bodies, independent consultants, academia, and government bodies. Workgroup member organizations include:
|Alliance of Crop Soil and Environmental Science Societies||OpenTEAM, Wolfe’s Neck Center for Agriculture and the Environment|
|California Department of Food and Agriculture (CDFA)||Salk Institute|
|Colorado State University||SES, Inc.|
|Continuum Ag||Shell International Exploration and Production Inc.|
|C-Quest Capital||Sierra View Consulting|
|Delta Institute||The Nature Conservancy|
|Goodson Ranch LP||TREES Consulting LLC|
|Indigo Ag, Inc.||University of California, Berkeley|
|Lamont-Doherty Earth Observatory at Columbia University||Viresco Solutions Inc|
|NativeEnergy||Woods Hole Research Center|
|Natural Resources Conservation Service||World Resources Institute|
Interested stakeholders are welcome to participate in the process as “observers.” Observers may attend workgroup meetings in listen-only mode, comment on the draft protocol when it is released for public comment, and attend the public webinar held during the public comment period. Please email [email protected] if interested in participating as an observer.
Following a request for such information, the Reserve would like to provide the following tabled summary of existing relationships between workgroup members and Indigo Ag, who is funding this work.
|Jonathan Sanderman||Woods Hole Research Center||WHRC soil lab processed samples from some of Indigo’s research sites. Dr. Sanderman also consulted on experimental designs for Indigo’s research teams. Both activities were compensated.|
|Ken Newcombe||C-Quest Capital||Informal advisor to Indigo as it builds its carbon business.|
|Max DuBuisson||Indigo Ag, Inc.||Employee.|
|Mitchell Hora||Continuum Ag||Participant in Indigo Carbon, recent small cash prize in the Carbon Cup competition.|
|Robert Parkhurst||Sierra View Consulting||Paid for consulting services to Indigo on a topic unrelated to the SEP.|
|Tom Cannon||Goodson Ranch LP||Participant in the Indigo Research Partners program, no cash payments.|
Note: Remuneration from Indigo Ag to listed parties has totaled $90,000 (excluding remuneration of Indigo Ag employee Max DuBuisson).
