The U.S. Soil Enrichment Protocol (SEP) provides guidance on how to quantify, monitor, report, and verify agricultural practices that enhance carbon storage in soils. The primary GHG benefit targeted is the accrual of additional carbon in agricultural soils, with hopes to incentivize GHG emission reductions from other sources, such as N2O from fertilizer use.

Project Registration Documents
| Document | Description | Required Phase | Privilege |
|---|---|---|---|
| Soil Enrichment Project Submittal Form | A proposal from a Project Developer to undertake a soil enrichment project. | Project Submittal | Public |
| Field Enrollment Form | A project developer uses this form to list enrolled fields in the project. | Project Submittal | Public |
| Project Area Map | Map that shows the general physical boundary of the project area. This is not the same as the georeferenced project boundary map (private) required during verification. | Project Submittal | Public |
| Soil Enrichment Project Implementation Agreement (PIA) | This template is for informational purposes only. The Reserve will send the Project Developer an Information Request Form during the verification review to collect the necessary information for completing the PIA. Once the project is close to registration, the PIA will be sent to the Project Owner for execution.
The PIA is a legal agreement between the Reserve and a Project Developer setting forth: (i) the Project Developer’s obligation (and the obligation of its successors and assigns) to comply with the U.S. Soil Enrichment Protocol, and (ii) the rights and remedies of the Reserve in the event of any failure of the Project Developer to comply with its obligations. The PIA is not recorded on the deed to the property. |
Verification | Public |
| Monitoring Plan and Report Template | This document is intended as a template to assist project developers in organizing project data, summarizing key aspects of a project, and to help facilitate verification. It is created at the beginning of a project, and updated over time as conditions change. It can also be used as an annual Monitoring Report for stating the project’s estimated annual emission reductions, attesting that the project is carrying out the intended project activities, and confirming that no reversals have occurred on the project area. | Verification | Public |
