Welcome to the online Manure Applicator Certification (MAC) Program.

The MAC program is a mandatory program based on state law that requires all commercial manure applicators and confinement site manure applicators with more than 500 animal units in confinement to be certified to handle, transport, or land-apply manure. Passing an examination or attending annual training can attain certification. Please keep in mind that education can only be used during the year it is taken, for instance, you cannot use education taken in 2022 to renew a certification in 2023.

Once you have completed the course requirements, you will be instructed on how to pay for certification and how to print off your certification.

Iowa State University Extension and Outreach works in cooperation with the Iowa Department of Natural Resources to provide the required training.
