AMES – Iowa State University Extension is hosting a manure management and runoff control demonstration field day from 10:30 a.m. to noon, on Monday at the Bob Ziegmann farm located near Wall Lake.

This field day will feature a system designed to keep manure runoff out of the road ditch and distribute it in a crop field instead.

The Ziegmann feedlot is at 3740 B Ave., Wall Lake. To get to the feedlot from Wall Lake, go south five miles on M64 and then 2.5 miles west on B Avenue.

Recent compliance enforcement from the Department of Natural Resources and Environmental Protection Agency has put the focus on runoff from small- to medium-sized feedlots.

“Small- and medium-sized open feedlots can potentially discharge significant amounts of nutrients to streams,” said Shawn Shouse, agricultural engineer specialist with Iowa State University Extension. “The nutrients can cause water quality problems in streams and present a loss of valuable fertilizer nutrients for the farm.”
