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.

As a reminder:
A Confinement Site Manure Applicator is "a person, other than a commercial manure service or commercial manure service representative, who applies manure on land if the manure originates from a manure storage structure". A confinement site is "a site where there is located a manure storage structure which is part of a confinement feeding operation, other than a small animal feeding operation". A confinement feeding operation mean "an animal feeding operation in which animals are confined to areas which are totally roofed". Confinement site applicators applying manure from a small feeding operation (SAFO) are exempt from being certified.
Confinement Site Applicators are required by law to pass an examination or attend two (2) hours of annual training. Your license is good for three (3) years, but you will need to attend training each year (if renewed using annual training). Your license will expire on December 31st of your third year. If you mess training in your three-year license, you will need to take a make-up exam at a DNR Field Office.- Teacher: Melissa McEnany
