Annual Implementation Reports (AIRs) documenting nutrient applications for Calendar Year 2025 are due to the Nutrient Management Program by March 1, 2026​. Farmers have two reporting options: 
  1. Farmers who want to submit their 2025 AIRs electronically should visit the Maryland OneSt​op Portal​​. Farmers new to Maryland OneStop will need to register for an account. Returning farmers should log in using the email and password you used to set up the account.​
  2. Farmers who want to submit paper reports may download either the standard AIR or the CAFO reporting form to their devices before completing.
