Confinement site manure applicators must become certified by October 1, 1999, under a new law passed by the Iowa Legislature. As a result, Iowa State University Extension is offering certification workshops in most counties. By attending a workshop and paying a certification fee to the Department of Natural Resources (DNR), manure applicators will become certified. The other option instead of attending a workshop is to pass a written exam. During the 2-hour workshop, which must be attended for the full length of time, applicators will learn what they need to know to become certified by the DNR
