Bagged Fertilizer Labels

​​​​​​​Bagged fertilizers distributed in Wisconsin must be conspicuously labeled with this information:

  • Brand or product name

  • N-P-K grade

  • Guaranteed analysis

  • Net weight

  • Name and address of the licensed manufacturer/distributor

If bagged fertilizers contain secondary or micronutrients, they must be listed as part of the product name or brand name, not as part of the N-P-K grade. For example, if the product contains 5 percent zinc, you cannot list the grade as 9-23-30-5Zn. Instead, you can include it in the product name: 9-23-30 with 5% zinc. Or you can list it in the brand name: Supe​​rGro Supreme 9-23-30 with 5% Zinc. ​
