: The Commercial Manure Applicator training re-show video will be shown the 2nd Thursday of each month. Pre-registration is required, the showing will be cancelled if there are no registrations by 4:00 pm the prior day. ISU Extension will charge a $10 fee to applicators who choose to view the certification materials on a non-scheduled re-show day at the county office. This fee will not apply to workshops or scheduled re-show days. Due to scheduling conflicts, many ISU Extenstion offices will no longer accept walk-in appointments to watch these videos.
