Commercial Fertilizer Dealers

​​​​​​​New - changes for the 2025-2026 Fertilizer License renewal and tonnage reporting term!

Online licensing and tonnage reporting - New this year, existing license holders can apply online for your annual Wisconsin Fertilizer license, report annual fertilizer tonnage, apply for product permits, and pay fees. Current license holders can follow these instructions​ for applying for a license on MyDATCP v3. ​​​Credentials for logging in were emailed to current license holders with their expiration notice.

Annual Fertilizer Tonnage Report and the fertilizer tonnage fees:
  • The Agrichemical Cleanup Program (ACCP) surcharge of $0.05/ton of fertilizer is due for fertilizer distributed in Wisconsin from July 1, 2024 to June 30, 2025, in addition to the $0.62/ton tonnage fee. This results in a new overall tonnage fee due of $0.67/ton or a minimum of $29, whichever is greater.

  • For each licensed location, a separate tonnage report is required. Previously, a business with multiple Wisconsin locations was able to submit a single tonnage report for all facilities. This practice will no longer be available. The connection between your new license and location specific tonnage report can be found in the List of Commercial Fertilizer and Soil or Plant Additives Dealers spreadsheet linked under the "Resources" sidebar.

License numbers changed to a six-​digit number (e.g. 654321). This replaces the previous 30-012345-012345 format. The new number, and the previous number it corresponds with, can be found in the List of Commercial Fertilizer and Soil or Plant Additives Dealers spreadsheet linked under the "Resources" sidebar.

Non-Agricultural and Special-Use Fertilizer Permits

If you distribute low-analysis fertilizers, you will need either a non-agricultural or special-use permit. Low-analysis fertilizers have less than 24 percent N-P-K. These permits remain in effect until you change the product's label or formulation. The permit fee is $25/permit, a one-time charge.

  • Non-agricultural fertilizers are used on gardens, lawns, golf courses, greenhouses and nurseries and other non-farm uses, and for research.

  • Special-use fertilizers are for product labeled for remedying nutrient deficiencies unique to certain crops or local areas.

  • You may also need a soil or plant additive license and permit​ if the fertilizer product also include substances that claim to improve plant growth, crop yield or quality, or soil properties.
