DES MOINES, Iowa (AP) – Time is running out for people who handle certain manure in Iowa to get certified without paying a fee.

The state Department of Natural Resources says manure applicators could face a $12.50 fee if they don’t get the necessary certification by March 1.

Iowa State University Extension and Outreach works with DNR to offer free training sessions. There’s about 15 left for confinement site manure applicators. Applicators who handle mostly dry manure have four remaining sessions.

State law says people handling, transporting or applying manure from certain confinements must be certified. Applicators will need to watch a training video or take an exam if they can’t attend a session. Additional fees may apply.
