Create a free account and enter basic operation information to check eligibility. Indigo provides a carbon calculator to estimate earning potential by location and practice change before enrolling. Enrollment is digital, and growers can review the terms and conditions of the Carbon contract during the enrollment process.

Carbon by Indigo Support

Carbon by Indigo pays farmers for carbon sequestered through practice changes on cropland, rather than&#x2004;a lump sum or single payment for practice change. The standard program returns 75% of the weighted carbon credit purchase price directly to the farmer, and farmers always take home 75% or more of the carbon credit average sale amount.


Credits are issued by the Climate Action Reserve (CAR), an independent third-party registry, which confirms their eligibility for sale. Indigo describes the program as the largest registry-approved agricultural soil carbon program in the market, with more than 2 million credits issued to date.

There are eight criteria your operation needs to meet to be eligible for the Carbon by Indigo program:

1. Location — fields must be located in an eligible state. The program is available across all 48 continental US states.
2. Land use — at this time, only cropland is eligible. Indigo states it aims to expand to other land use types, such as pastureland, in the future.
3. Crops — you must grow a currently supported crop on the fields you would like to contract, and have exclusively planted eligible crops on those fields in the last five years (excluding crops grown as covers). Eligible crops: alfalfa, barley, dry beans or peas, canola, corn, cotton, flax, millet, oats, peanuts, rye, sorghum or milo, soybeans, sugar beets, sunflowers, triticale, wheat.
4. Practice change — you must make a practice change on your farm. Eligible practices include planting cover crops, reducing tillage, diversifying crop rotation, and improving nitrogen timing. Cover crops are the best way to maximize payment.
5. Other programs — fields currently enrolled in other carbon credit programs are not eligible. Fields under some conservation agreements may also be ineligible: fields in CRP are ineligible, but fields utilizing EQIP or CSP are eligible.
6. Tenure — fields must have been used in agricultural production for at least the past ten years.
7. Uncommon situations — a few scenarios may make a field ineligible, including clearing native ecosystems, farming on histosols, reclaiming mining land, and adding tile drains during the Carbon contract period.
8. Record keeping — you are required to submit detailed field records, which may include planting dates, fertilizer type, and application method, depending on your operation.

Indigo also states the program is open to farmers who grow any of 18 types of crops on at least 150 acres, enrolling at least one field.

A contract to sell an environmental outcome the operation produces - sequestered carbon, a water-quality credit, a habitat credit - to a buyer, rather than receiving an award. Payment is typically per unit (per acre or per ton CO2e) over a multi-year term and contingent on verification, so records using this instrument carry the payment.* and contract.* fields rather than award.min/award.max. Covers both credit-generating programs, where credits are sold to outside buyers, and supply-chain insetting programs, where a company the operation already sells to pays for the practice.

Payments are based on performance — the number of verified carbon credits generated on enrolled land and sold to a third-party buyer.

All payments under Carbon by Indigo are subject to multi-year vesting and are contingent on continued long-term maintenance of regenerative agricultural practices and soil carbon levels. Indigo's disclosure states payments are "paid on a five-year schedule."

All carbon credits generated are subject to a buffer pool holdback of up to 20% of credits generated, required by third-party crediting to protect against reversals; participants will not receive payments for the holdback.

Indigo states that even if farmers choose to discontinue carbon farming with Indigo, they will never be asked to pay back money they have been paid.

Growers participate through Indigo's sustainable sourcing programs; see the program page to engage.

Indigo Ag — General

Source by Indigo operates sustainable sourcing initiatives focused on emissions reductions, helping design water programs (from understanding water usage in crop cultivation to implementing water conservation programs) and running low-CI feedstock programs with farmers to generate revenue from clean fuel markets (Scope 3 sourcing).



Growers/farmers are the primary participants in Source by Indigo programs.

Alternative Energy

The program enables farmers to participate and maintain profitability through meaningful incentives for sustainable practices — farmers can earn a premium for their efforts when implementing strategies to reduce their inputs and footprint.

Start with the pre-enrollment form at truterraag.com/enroll, or work through a local Truterra network provider (typically the local ag retailer or co-op). Eligibility is evaluated through the Truterra MyPortal platform; data collection covers the current crop year plus four historical years, and a small portion of enrolled farmers may be selected for soil sampling or verification.

The 2025 cycle enrolled June 26 to September 2, 2025 (or until the 400,000-acre cap), with data collection due September 18, 2025 and filing due January 21, 2026. A 2026 cycle had not been published as of August 2026.

Questions: support@truterraag.com or a local Truterra network provider.

Truterra Support

The Truterra Registered Carbon Program with Indigo pays farmers a share of registry-certified carbon credit sales for adopting new regenerative practices. Truterra, Land O'Lakes' farmer-driven sustainability company, runs the program jointly with Indigo Ag under a strategic&#x2004;collaboration announced in November 2024 — farmers get Truterra's hands-on, retailer-network support while generating credits through Indigo's registry-certified carbon project.


Farmers receive 55% of the project-level average credit selling price on the credits their fields generate, and Truterra may make an advance payment — estimated at $20 per metric ton — after credit issuance and before credit sale completes.


The program runs on annual enrollment cycles with a per-cycle acreage cap (the 2025 cycle capped at 400,000 acres). Truterra reports its carbon programs have paid over $21 million to farmers to date.

From the 2025 program cycle (the most recent published):

- Geography: 32 states — AL, AR, DE, FL, GA, IA, ID, IL, IN, KS, KY, LA, MD, MI, MO, MN, MS, NC, ND, NE, NY, OH, OK, OR, PA, SC, SD, TN, TX, VA, WA, WI. County-level restrictions may apply where a practice is already common.
- Field size: 1-acre minimum per field.
- Eligible crops: barley, canola, corn, cotton, dry beans or peas, flax, hemp, millet, oats, peanuts, rye, grain sorghum or milo, soybeans, sugar beets, sunflowers, triticale, and wheat. Baseline history must include only eligible crops, alfalfa, or up to 2 years of fallow.
- Practice change required in the enrollment crop year, on an eligible crop. Core practices (at least one): cover crop usage, strip/no-till, or adding a legume species to an existing cover crop mix. In counties where a core practice is already common, a supplementary practice is also required: longer-duration cover crops, a new cash crop in rotation, or nitrogen enhancement.
- Practice changes are rotation-based: adopting a practice on a new crop type may qualify even if the practice was used on the field with a different crop before.

How payment works. The farmer's total payment is 55% of the project-level average credit selling price on the credits their fields generate, determined after the project's credits are sold (weighted average). Truterra may make an advance payment, estimated at $20 per metric ton, after credit issuance and before sale completes — discretionary and not guaranteed; the final payment is then the remainder. Payments for the 2025 cycle are anticipated in 2027-2028, depending on credit issuance and sale timing.

Contract term. An annual carbon offer plus a 5-year practice-maintenance and data-reporting period following the contracted year (for the 2025 cycle: 2026-2030).

Stacking. Disclosure of publicly funded conservation program participation is required for verification, and responses are unlikely to affect eligibility. Fields may not be enrolled in another privately funded or incompatible program during the contracting period.
