- U.S. Nitrogen Management Protocol Version 2.1 (December 3, 2021)
- U.S. Nitrogen Management Protocol Summary of Changes from V2.0 to V2.1
The U.S. Nitrogen Management Protocol underwent a technical update to Version 2.1. The revision clarifies guidance to project ownership, credit stacking, baseline guidance and terminology for nitrogen use efficiency. The update also adds some flexibility for project development and verification such as an option for a 24-month initial reporting period and moving from field-level sampling to field-manager sampling for verification.
- U.S. Nitrogen Management Protocol Version 2.0 (October 17, 2018)
- U.S. Nitrogen Management Protocol Summary of Changes from V1.1 to V2.0
With the generous support of the U.S. Department of Agriculture, Natural Resources Conservation Service, under the Conservation Innovation Grant program, the Reserve revised and expanded the U.S. Nitrogen Management Protocol (NMP). The revised protocol includes a standardized quantification methodology that incorporates additional regions, crops, and nitrogen management practices; updated project, aggregate, and ownership structures; modified benchmarks for the performance standard test; and several other revisions to enhance usability. For a comprehensive list of all revisions, see the Summary of Changes above. Version 2.0 of the protocol was adopted by the Reserve Board of Directors on October 17, 2018.

Nitrogen Management Survey
In late 2016, the Reserve issued a Nitrogen Management Stakeholder Survey to gather feedback and recommendations from stakeholders involved in the development and/or implementation of the NMP and/or other agricultural offset protocols and methodologies on the future expansion of the protocol. The results of the survey are summarized in the memo below.
- Nitrogen Management Survey Results Memo (March 7, 2017)
On March 15, 2017, the Reserve held a webinar to go over the results of this survey, the biggest takeaways, and next steps for the protocol revision as discussed in the memo. Meeting materials are available below.
Proposed Protocol Expansion
In January 2013, the Packard Foundation awarded grant funding to the Reserve in order to explore the potential for an expansion of the U.S. Nitrogen Management Protocol. The undertaking had the two-part goal of building out and formalizing the new data submittal and assessment process, and taking a pre-selected, high-quality data set through the process. As a case study, the Reserve worked closely with Ardell Halvorson and Steve Del Grosso at Colorado State University to evaluate their study (Halvorson et al., 2013) on N2O emissions from fertilizer management on irrigated corn in Colorado against the Minimum Data Standard. The assessment of the Colorado data set was very positive overall, meeting or exceeding most criteria in the Minimum Data Standard. However, the Reserve determined that it could not use the Colorado data set to move forward with an expansion at this time, as it failed to meet Reserve criteria in one critical area: replication of the study in other study sites (i.e. other sites within the county, state, region). See the resources below for more information:
- U.S. Nitrogen Management Protocol Version 1.1 (January 17, 2013)
- Summary of Changes from Version 1.0 to Version 1.1
The U.S. Nitrogen Management Protocol underwent a technical update to Version 1.1. The revision expands protocol applicability to tile drained fields in the North Central Region, allows for projects to be implemented on land designated as highly erodible land (HEL) with USDA conservation plans in place, and incorporates a number of technical revisions to improve clarity.

- U.S. Nitrogen Management Protocol Summary
The Reserve began scoping agriculture protocols in October 2010 and began actively developing the U.S. Nitrogen Management Protocol in April 2011. The technical workgroup met from April 2011 to April 2012 to refine the draft protocol. A public workshop was held in May 2012 to discuss the draft protocol which was available for public comment through April and May 2012. The final protocol was approved by the Reserve Board on June 27, 2012.
The Reserve hosted a public workshop on May 9, 2012 in Sacramento, CA, to provide a venue for feedback on the draft U.S. Nitrogen Management Protocol. Workshop materials and meeting video are available below.
The Reserve worked closely with a multi-stakeholder workgroup to develop the U.S. Nitrogen Management Protocol. The workgroup included industry representatives, federal agency personnel, environmental organizations, verifiers and expert consultants. The workgroup included representatives from:

U.S. Nitrogen Management Protocol Version 1.0 Workgroup Draft (July 27, 2011)
- The Reserve together with the Nicholas Institute of Duke University assembled a group of leading scientific experts to form a Science Advisory Committee (SAC). The purpose of the SAC was to help the Reserve interpret and apply the best available science into the U.S. Nitrogen Management Protocol. Committee membership was by invitation from the Reserve and the Nicholas Institute and was based on scientific expertise, knowledge of GHG offset protocol development issues, and explicit interest in translating research into GHG mitigation policy applications for agriculture.
The Reserve held an all-day workshop for the SAC on September 7, 2011 and the summary report is available below.
SAC Meeting Summary (November 22, 2011)
- The Reserve formed a Credit Stacking Subcommittee to help inform policies to evaluate project sites where multiple ecosystem service credits or payments may be available. This subcommittee was made up of workgroup members and invited experts.
