The Siemer-STAR Producer Reward Payment Program (PRPP) will open in June, and new Siemer Milling Company (SMC) customers are welcome to apply! With an $10,000 cap per farmer and a $75,000 cap overall, this program is expected to be reached very quickly, so make sure to submit all paperwork ASAP!
The Siemer Milling Company Producer Rewards Payment Program uses the STAR Rating to compensate farmers for improved or outstanding (5-STAR) STAR Rating, thereby recognizing a range of conservation efforts rather than requiring specific practices. This flexibility allows farmers to choose the conservation approaches that best fit their operation while still being rewarded for their commitment to soil health and sustainability. This program will be offered from 2025-2027 with guaranteed backing.

SMC customers’ corn, soybean, and wheat fields are eligible to participate. If you have sold wheat to SMC in the past five years (including this year), you must also submit a SMC Grower Agreement AND use the STAR Tool to get a STAR Rating on the fields listed in the Grower Agreement. STAR provides each field a confidential rating of 1 to 5 STARs. Until 400 acre cap is reached, producers receive payment for:
Step 1: Get a STAR rating for each field at www.startool.ag
Step 2: Contact your SMC representative to receive and complete a Grower Agreement with all fields listed for consideration.

June 1st: Enrollment opens.
August 31st: Grower Agreements and
STAR Rating completion due.
October 1st: STAR Verification begins.
October 16th: Approved growers are notified of payment
December 15th: STAR Verification ends; payments are finalized by Siemer
1. Siemer customers' corn, soybean and wheat fields are eligible to participate (must have been a Siemer Milling Company customer (delivered wheat) within the last 5 years or in 2026). There is a 400 acres/grower/year cap.
2. Prioritization (if needed) will be first come, first served, using the date the signed Grower Agreement is received.
3. STAR encourages stack ability of payment programs to fully cover producers' cost of practice implementation. Other private carbon market programs may have restrictions that prohibit additional producer payments for fields that are enrolled. Producers should check the rules of any other program they are participating in before committing to this program. Fields enrolled in publicly eligible programs, like USDA- or state-based conservation programs, are eligible.
4. A small subset of STAR fields is randomly selected each year for verification and quality control. Verification will occur in late 2025. If a field that is participating in this program is randomly selected, the grower will be notified by a STAR representative.
5. No backsliding: In subsequent years of STAR’s Producer Reward Payment Program, fields will not be eligible for a payment if they were previously rewarded for a certain STAR Rating Improvement. For example, in the image below, Field A received a payment for achieving an improvement from 2 to 3 STARs; this same field would NOT be eligible to receive a payment if the field went back down to a 2-STAR rating and went back up to a 3-STAR rating. It would only be eligible for another incentive payment when it achieved a 4-STAR rating, or the flat payment for a 5-STAR rating.
