Liming Licenses

• All agricultural liming materials manufactured or distributed in Michigan must be licensed with the Michigan Department of Agriculture & Rural Development (MDARD) by the manufacturer/distributor.
• A distributor is not required to obtain a license if they are selling liming materials of a manufacturer/distributor that is already licensed and the principle mailing address of the licensed manufacturer/distributor appears on the labeling.

A copy of the label or invoice statement must be submitted when applying for a liming license. The label/invoice must contain the following information:

• The net weight (volume if material not sold on a scale weight basis)
• Product name
• Name and address of manufacturer or distributor
• Minimum neutralizing value in terms of calcium carbonate
• Degree of fineness expressed as minimum percentage passing through an 8-mesh, 60-mesh, and 100-mesh screen

Note: Marl and refuse lime materials (sugar factory, paper mill, carbide, water treatment, mater softener, wood ash, etc.) do not need to state the degree of fineness on the label/invoice. Instead, the minimum neutralizing value may be identified as "X" lbs per cubic yard (expressed as calcium carbonate equivalent).

Any change in the ownership of a licensed firm will require an application and fee for a new license.

Companies with a change of name and/or address will need to send written notification to MDARD so records can be updated accordingly.
