Both the MDA and Minnesota Pollution Control Agency (MPCA) have roles in regulating land application of biosolids (PDF | MPCA) and industrial byproducts (PDF | MPCA). MPCA performs all the permitting and site approval (when applicable) for land application of these materials. The MDA registers products comprised of these materials to be sold in the state of Minnesota. These processes are separate, and both may be required for products sold in Minnesota to be compliant with state laws.
Land application of biosolids (MPCA) is a common practice in Minnesota. Biosolids are a nutrient-rich component of municipal wastewater treatment commonly used as a soil amendment. During wastewater treatment liquids are separated from solids. The solids portion of wastewater treatment are then further biologically or chemically treated to produce a semisolid known as biosolids. When biosolids are applied to the land at appropriate rates, they provide a nutrient addition and improved soil structure.
An industrial byproduct (MPCA), also known as an IBP, is a byproduct of an industrial, commercial, mining, or agricultural operation. IBPs from food, beverage, and agricultural operations such as vegetable, dairy, and meat processing wastes typically contain nutrients that make them good candidates for land application.

Labels Must Include the Following
- The Brand Name of the fertilizer.
- The fertilizer Grade, which is the percentage of Total Nitrogen (N), Available Phosphate (P2O5) and Soluble Potash (K2O) and expressed in the same percentage, order and form as in the guaranteed analysis statement. For example: 10-10-10.
- The Guaranteed Analysis statement in the following format:
Nutrient Percentage Total Nitrogen (N) % Ammoniacal Nitrogen % Urea Nitrogen % Water Insoluble Nitrogen % (Other recognized and determinable forms of N)
Note: The forms of N, when listed, must add up to the
Total Nitrogen (N) guarantee *% Available Phosphate (P2O5) % Soluble Potash (K2O) %
When other plant nutrients in addition to Nitrogen (N), Phosphate (P2O5) or Potash (K2O) are guaranteed, they must be listed in columnar form immediately below the primary nutrient guarantees and be in the order and minimum percentages listed below:
| Primary nutrient | Minimum percentage |
|---|---|
|

If the percentage of any plant nutrient is zero, the plant nutrient must be omitted from the guaranteed analysis statement.
* The nitrogen breakdown statement is only required when slow release or organic nitrogen properties are claimed or guaranteed.
- A Derivative Statement must be placed immediately below the guaranteed analysis statement. Sources of plant nutrients shall be listed by their common or usual English name for the ingredient. But In addition, non-plant food materials used to blend a fertilizer may not be listed in the derivative statement. This includes but is not limited to lime fillers.
- The Name and Address of the Guarantor.
- A Net Weight statement expressed in ounces, pounds, or tons avoirdupois.
- A Directions for Use Statement must be listed on all specialty fertilizer product labels. This may be expressed as the amount (lbs) of fertilizer recommended to be applied per unit area (1,000 sq. ft.) or the area the entire contents of the container will cover.
These specifications represent the minimum information that must be placed on a specialty fertilizer product label. If additional information is provided on the label, further labeling requirements may be enforced. Therefore, you should consult with us for a label review prior to final printing. In addition, we recommend that you review Minnesota Rules, 1510.0410 to 1510.0422 on the Fertilizer Labeling before printing a label.
Sale, distribution, or use of existing stock of XtendiMax®, Engenia®, and Tavium® is no longer allowed. However, the EPA issued an order. on February 14, 2024 (revised on March 12, 2024), that allows existing stocks of these products to be distributed solely for the purpose of returning them to the registrants or for proper disposal, with no end date. Individuals and entities, including end users possessing these stocks (excluding the registrants), are allowed to return them to the registrants or dispose of them in accordance with all applicable federal, state, and local waste disposal regulations.
If you have OTT dicamba products (i.e., XtendiMax®, Engenia®, and Tavium®) that need to be disposed of, check with your dealer, co-operative, or ag retailer to see if they will take back products. If they will not, please use the MDA's Waste Pesticide Collection Program. For larger volumes (over 300 pounds), call the MDA’s Jane Boerboom at 612-214-6843.
OTT dicamba was used to control broadleaf weeds, particularly those resistant to glyphosate and other herbicides, in DT soybeans in Minnesota. The loss of this tool emphasizes the need for diversified weed management, including a combination of preemergence residual and postemergence herbicides with multiple sites-of-action to reduce resistance development and broaden weed control. While not specific to Minnesota, the University Extension crop and pest management guides below provide valuable information on various weed control options. Always consult the MDA's registered product search tool to verify that any pesticide products you plan to use is registered in Minnesota. Always read and follow label instructions carefully before using any pesticide. The Label Is The Law!
