Cover Crop and Fieldprint Calculator Subpilot

If you are enrolled in the Cover Crop & Fieldprint Calculator Subpilot, use the steps below to stay on track with program requirements. Additional resources are available at the link below.

By September 30, 2026

Create your Fieldprint Calculator account. Create an account using the same name and email address used on your Alliance application and opt into the Alliance project. You do not need to complete your full Fieldprint Calculator report yet. Additional instructions and a webinar will be provided later.

Beginning October 1, 2026

Upload an updated 2027 FSA Subsidiary Print to your dashboard. The federal fiscal year begins October 1, and an updated Subsidiary Print will be required before your final payment can be issued.

The program provides $150 per enrolled acre, paid in two installments of 50% each.

When You Plant Your Cover Crop

Plant your cover crop by the deadline for your region:

• Mountain: October 27
• Piedmont: November 1
• Coastal Plain: November 17

Keep a record of what you actually plant, even if it differs from what you originally proposed in your application. You will need this information later, including your cover crop species or mix, seeding rate, planting date and method, and relevant cash-crop information.

Multi-species cover crop mixes are encouraged but are not required for most participants. If you are already receiving support for cover crops through another program, additional requirements may apply.

If your farm, tract, or field numbers change, contact the Alliance as soon as possible. Changes may affect your enrolled acreage, agreement, or payment.

Before Spring Field Operations

All enrolled producers will complete biomass sampling in the spring. Sampling should generally take place one to two days before you terminate the cover crop, plant green, or begin termination through grazing.

If someone other than you manages or performs field operations, make sure they know biomass sampling must happen before spraying, planting, grazing, or other activities that could affect the cover crop.

Grazing is permitted as long as at least four inches of cover remain. Cover crops may not be harvested for seed, hay, or haylage.

By the End of May 2027

To complete the program and receive your second payment, you will need to complete the remaining program requirements, including:

• Cover Crop Practice Worksheet
• Fieldprint Calculator report
• Biomass sampling
• Required exit surveys

Additional instructions, webinars, and reminders will be provided throughout the program.

Click below to review the practice requirements and access the worksheet. The completed self-verified worksheet serves as documentation that the practice was implemented and is required to receive your final payment.

As part of the Cover Crop and Fieldprint Calculator Subpilot, enrolled producers will participate in cover crop biomass sampling to support research conducted by the Virginia Tech Agronomy Team.

Producers will be asked to:

• Collect cover crop biomass samples from their enrolled fields following the provided sampling protocol.
• Record the GPS location where each biomass sample is collected.
• Record the wet weight of each sample and mail the samples for laboratory analysis.
• Complete sampling before the cover crop is terminated or otherwise disturbed. If planting green, sampling should occur at planting. If grazing is used for termination, sampling must occur before grazing begins.
• Complete the required program surveys and provide the management information requested through the Practice Worksheet and Fieldprint Calculator.

Biomass samples will be analyzed for information such as nutrient content, carbon-to-nitrogen ratio, and fresh and dry matter yield. The results will help support the Alliance’s agronomy research and provide additional information about cover crop performance. See the Biomass Sampling Protocol tab for more information.

Additional research opportunities may be offered to producers during or after the program. Participation in research activities outside of the requirements listed above will be voluntary.

Click below for step-by-step instructions on collecting and submitting your cover crop biomass samples, including the equipment you’ll need, when and how to collect your samples, and how to prepare and submit them for analysis.

Email or text message is the preferred method of contact. Please include your name, if you are enrolled in the subpilot, and briefly describe your question or issue. This allows us to quickly understand the situation and determine how best to help. If needed, we will call you as soon as we are available.

What is the Fieldprint Calculator?

The Field to Market® Fieldprint Calculator is an online tool developed by Field to Market that uses information about your fields and management practices to evaluate environmental outcomes associated with crop production. As part of this subpilot, you will use the Calculator to enter information about your enrolled fields and generate a Fieldprint report.

Is the Fieldprint Calculator required?

Yes. Completing the Fieldprint Calculator is a requirement of the Cover Crop and Fieldprint Calculator Subpilot. You will need to create an account, enter the required field and management information, opt into the Alliance project, and submit your completed Fieldprint report.

When should I create my account?

Create your Fieldprint Calculator account as soon as possible using the same name and email address you used for your Alliance application. You can create your account and opt into the Alliance project now; you do not need to complete all of your field data immediately.

Additional guidance will be provided to help you complete the remaining data entry.

What information will I need?

The Fieldprint Calculator requires detailed information about your enrolled fields and farming practices. This includes field preparation, planting, crop management, harvest, cover crop planting and termination, and the approximate dates these activities occurred.

You will need to provide information for at least one full crop rotation. For example, your field history might include:

2024: Corn → Cover Crop
2025: Soybeans → Cover Crop
2026: Corn → Cover Crop
2027: Soybeans

Because the Calculator asks about your actual field management, keeping good records throughout the program will make completing your report easier.

What if I don't know the exact dates of past field operations?

Use the most accurate information available from your farm records. The goal is to provide a complete picture of how the enrolled field has been managed. Additional guidance will be provided as you begin entering your historical field information.

Why is the Alliance requiring the Fieldprint Calculator?

The information collected through the Fieldprint Calculator helps the Alliance meet program reporting requirements and supports research conducted by the Virginia Tech Agronomy Team.

The Calculator also provides you with field-level metrics related to areas such as greenhouse gas emissions, energy use, water use, soil and land management, nutrient and fertilizer management, and crop protection inputs.

Will I receive a report?

Yes. The information you enter is used to generate a Fieldprint analysis for your field. You will be required to save and submit your completed Fieldprint report to the Alliance as part of your program requirements.

Where can I get help?

You do not have to figure out the Fieldprint Calculator on your own. Step-by-step resources, webinars, and technical assistance will be available throughout the program. We recommend gathering your field records before beginning detailed data entry and following the Alliance instructions provided for setting up your fields and completing your report.

How much will I be paid?

The Cover Crop and Fieldprint Calculator Subpilot provides $150 per enrolled acre, for up to 120 acres.

Payments are issued in two installments of 50% each over the course of the program.

What is required to receive my first payment?

Before your first payment can be issued, you must have a signed Producer Agreement and meet all applicable program eligibility requirements.

Because the new federal fiscal year begins October 1, you will also need to provide the Alliance with an updated 2027 FSA Subsidiary Print. Instructions for submitting your updated document will be provided by the Alliance.

What is required to receive my final payment?

Your final 50% payment will be issued after you have completed the remaining program requirements, including:

• Implementing your enrolled cover crop practice
• Completing and submitting your Practice Worksheet
• Completing the required cover crop biomass sampling
• Completing your Fieldprint Calculator requirements
• Completing the required exit survey

All program requirements must be completed before your final payment can be processed.

When do I need to plant my cover crop?

Planting deadlines are based on the location of your enrolled fields:

Mountain Region: October 27, 2026
Piedmont Region: November 1, 2026
Coastal Plain Region: November 17, 2026

Your cover crop must be planted by the applicable deadline for your region.

When can I terminate my cover crop?

Your cover crop may be terminated before planting your following crop, but no more than two weeks before planting.

If you plan to plant green, you may terminate the cover crop after planting the following crop.

Remember that your required biomass sampling must be completed at the appropriate time before the cover crop is terminated or otherwise disturbed.

When does the program end?

Producer Agreements for this subpilot end May 31, 2027. Required program materials and activities must be completed in time for the Alliance to verify your requirements and process your final payment.

What if something changes with my enrolled fields?

Contact the Alliance as soon as possible if there are changes to your farm, tract, field numbers, ownership, or other enrollment information. Changes may affect your Producer Agreement or payment and may require an amendment before your payment can be processed.

$150 Per Acre

Producers enrolled in the Cover Crop and Fieldprint Calculator Subpilot are eligible to receive $150 per acre, for a maximum of 120 acres. This enhanced payment recognizes both the implementation of a winter cover crop and the additional time required to provide detailed farm management information through the Field to Market Fieldprint® Calculator.

Valuable Operational Insights

Participating producers will receive estimated sustainability metrics for their operation, including greenhouse gas emissions, energy and water use, soil and nutrient management, and other conservation outcomes. These insights can help you better understand the impact of your management practices and identify opportunities for continuous improvement.

Producers may also have opportunities to learn how this information can support future marketing efforts, participate in educational webinars, and explore emerging market opportunities with industry partners.

The Cover Crop Subpilot is open to eligible producers in all Virginia counties who plan to establish or enhance a winter cover crop during Fall 2026. Applications will be open from July 6 - August 3.

While all eligible applications are encouraged, preference may be given to:

• New producers enrolling in the Alliance
• Producers planting legume cover crops that may help offset nitrogen fertilizer needs for the following cash crop
• Producers planting multi-species cover crop mixes that include a legume
• Producers managing multiple fields with different cover crop species or mixes, allowing for comparisons of cover crop performance across production systems.

Applications are open July 6 through August 3, 2026. No applications will be accepted after August 3. Complete applications will be submitted for selection on Friday, August 7. If an application does not include the required information and documents by August 7, it will not be considered.

All contracts will conclude on May 31, 2027.

Producers who have previously participated in the Alliance may be eligible to apply if they:

• Have completed no more than one previous Alliance contract
  • If you've completed only one previous Alliance contract, you're still eligible to apply for the Cover Crop and Fieldprint Calculator Subpilot. This also applies if you participated in the voluntary COMET-Farm contract. Although COMET-Farm has its own agreement, it is considered part of your original Alliance participation and does not count as a second contract.

Alliance producers previously enrolled in cover crops may also be eligible to enroll again if they enhance their cover crop system by either:

• Adding a species from a different functional group to their existing cover crop mix; or
• Planting a cover crop mixture that includes at least three species.

The program supports both new cover crop adoption and improvements to existing cover crop systems.

Practice Implementation

• Producers may enroll up to 120 acres of winter cover crops;
• Cover crops may consist of grasses, legumes, brassicas, forbs, or multi-species mixtures

Biomass Sampling Protocol

Participating producers will collect one cover crop biomass sample from each enrolled field shortly before cover crop termination or cash crop planting. The process includes clipping and weighing aboveground biomass from a designated sampling area, recording the sample location with GPS coordinates, measuring average cover crop height, and taking two photographs of the stand. A small subsample will be submitted for laboratory analysis to measure nutrient content and cover crop performance. Detailed instructions, sampling protocols, and required materials will be provided before sampling begins, and the Alliance research team will be available to answer questions throughout the process.

Cover Crop Planting Dates
Planting dates are based off where the farm is located.

Mountain: October 27, 2026
Piedmont: Nov 1, 2026
Coastal Plain: Nov 17, 2026

Termination Date

What to Expect After Selection

If you are selected to participate, a few next steps will appear in your dashboard to help you get started. These steps are designed to guide you through enrollment and set you up for success in the program.

First Steps

• CPA-52 Environmental Evaluation (No Action Required)
  • A CPA-52 Environmental Evaluation is required for each enrolled practice. The Alliance team will complete and submit this on your behalf. Once approved, it will be uploaded to your dashboard.

These steps must be completed before your Producer Agreement and additional tasks become available.

Next Steps

Once the above items are complete, you will be able to access the following:

Producer Agreement

• Accept or decline your enrollment offer
• Review your responsibilities for implementing practices and reporting data
• Your contract begins once the agreement is signed
• Please review carefully — agreements cannot be changed after signing
• If updates are needed (such as changes to practices or FSA information), you will need to contact the Alliance team for assistance

Practice Worksheet

• This worksheet will become available after your agreement is signed
• You may begin working on it at any time

Soil Biomass Sample

• Collect and submit your required soil or biomass sample following the instructions provided in your dashboard.

Program Surveys

As part of the program, you will also be asked to complete a few short surveys. These help improve the program and demonstrate its impact:

• Program Experience Survey
• Virginia Tech Exit Survey (administered by the Department of Agricultural and Applied Economics)
• USDA Marketing Commodities Survey
• Practice Exit Survey

If you have questions at any point, the Alliance team is here to help.

Yes.

If a cover crop has been implemented in the past, on the fields you plan to enroll you must:

• Add an additional species to the cover crop mixture that is implemented during the time of this contract, and that additional species must differ in functional group from the original species used.
• Cover crops are typically grouped by plant type as grasses, legumes, crucifers, and forbs. If the previous species/mixture contained only grass-type species, you must add a legume, crucifer, or forb-type species to fulfill the requirement.
• If the previous cover crop contained a mixture of 3 or more species and all 3 species are from different functional groups, no additional species will be required. However, the composition of the cover crop mixture may be adjusted as long as it complies with the NRCS standards and specifications.

The subpilot includes a research component designed to improve understanding of how winter cover crops perform under a variety of real-world farming conditions across Virginia. Information collected through the program will help researchers evaluate conservation outcomes and develop recommendations that benefit producers.

The research is led by Mark Reiter and Joseph Haymaker with the Eastern Shore Agricultural Research and Extension Center and Ryan Stewart with the School of Plant and Environmental Sciences at Virginia Tech. Their research focuses on cover crop management, soil health, nutrient use efficiency, and on-farm conservation practices. Producer participation will help strengthen research conducted under Virginia growing conditions and support science-based recommendations that improve the productivity, profitability, and sustainability of Virginia agriculture.

As part of the program, participating producers will be asked to provide operational information, including:

• Cover crop management details and field information.
• GPS coordinates for locations where cover crop biomass samples are collected.
• Cover crop biomass sample results and related laboratory reports, if applicable.
• Sustainability metrics generated through the Field to Market Fieldprint® Calculator.

Some additional research opportunities may be available outside of the required contract activities. These are completely voluntary and may include sharing corn tissue sample results, yield monitor data, nitrogen management information, or participating in on-farm nitrogen rate trials.

Researchers will provide clear instructions and protocols for any required sampling activities before they begin. Producers will not be asked to complete unexpected research requirements after enrolling in the program.

The Field to Market® Fieldprint Calculator is an online sustainability assessment tool that allows producers to enter information about their farming operation and receive insights related to soil management, nutrient use, water use, energy use, greenhouse gas emissions, and other sustainability indicators. Producers enrolled in the program will be required to create an account and enter farm management information into the platform.

The information collected through the Fieldprint Calculator and other program activities helps satisfy program reporting requirements, supports Virginia Tech research efforts, and provides participating producers with valuable information about their operation.

As part of participation, producers will enter information about their farming operation into the Fieldprint Calculator, including field management activities and approximate dates for a minimum of one full crop rotation.

Information entered may include:

• Field preparation and tillage activities
• Planting dates and crop information
• Fertility and nutrient management practices
• Pest and weed management activities
• Harvest operations
• Cover crop planting and termination

For example, a producer may provide information for a crop rotation such as:

• 2024: Corn followed by a cover crop
• 2025: Soybeans followed by a cover crop
• 2026: Corn followed by a cover crop
• 2027: Soybeans

Additional resources, training materials, and technical assistance will be provided to help producers complete the Fieldprint Calculator requirements.

Soil & Water Conservation Districts will be accepting applications for the Virginia Agricultural Cost-Share (VACS) Program during the same time period as this opportunity. Producers who are not selected for the Alliance program may still have an opportunity to apply for VACS.

Please note that the same acres cannot receive funding through both the Alliance program and VACS for the same practice. Producers enrolled in the Alliance may still enroll additional acreage in VACS, provided the acres are not already enrolled in the Alliance program.

VACS requirements and payment rates may differ depending on the cover crop practice being implemented.

All payments will be issued by Virginia Tech.
