Fertilizer, Plant Amendment, Plant Biostimulant, and Soil Amendment Program


Fertilizer means any substance containing one or more recognized plant nutrients that is used for its plant nutrient content and that is designed for use or claimed to have value in promoting plant growth of health, except unprocessed animal or vegetable manures. The fertilizer program provides for the registration, inspection and analysis of all commercial fertilizer products sold in Vermont.

Soil Amendments, Plant Amendments and Plant Bio Stimulants

With the passage of S102/Act 41, soil amendments, plant amendments and plant bio stimulants need to be registered with the state of Vermont starting in December 2021. The registration fee is $85 per product. You can find more information here.


Fertilizer Sample Reports

The purpose of the inspection and analysis is to ensure that fertilizer users are receiving a product that meets the chemical guarantee specified by the labeling. The statutory authority for the program is found in 6 V.S.A. Chapter 28.

Penalties are assessed to manufacturers for products that are deficient in nitrogen, available phosphoric acid or phosphorous, and soluble potash or potassium content. The value of the penalty is based on the labeling guarantee percentage, the percent deficient and the total sample weight. If a product is consigned to a consumer then the penalty is paid to that person. If no person is identified, then the penalty is paid to the Agency. No penalties are assessed for trace mineral violations. Annual analysis summary reports are available through the Agency. 


Fertilizer Fees

Fertilizer manufacturers and dealers are required to register their commercial products with the Agency. The annual registration fee is $85 per product. The registration fees directly fund the sampling and analysis program. Fertilizer tonnage fees are also required. The fees are $.50 per ton for Agricultural products sold in Vermont and $30 per ton for non-agricultural products sold in Vermont, or a minimum of $150.


Fertilizer Labels

Per Vermont Statute, all fertilizer products sold in the state of Vermont must be registered with proper labeling. Please review our Fertilizer Product Label Registration Guidelines  to make sure your label is compliant.
