Iowa State University (ISU) Extension and Outreach is hosting a manure management and runoff control demonstration on Aug. 26, from 1:00-3:00 p.m. at the ISU Armstrong Research Farm located near Lewis, IA. The demonstration will review low-cost options for managing water and manure runoff from small- to medium-sized beef and dairy feedlot operations.

The demonstration will look at a vegetated treatment area and illustrate how pumping effluent into cropland is a low-cost handling option for feedlot runoff. According to Kris Kohl, ISU Extension field agricultural engineer, "Pumping effluent onto cropland is not a common practice in Iowa, but by doing so we can reduce the potential for nutrients to reach the stream and the effluent can provide nutrients and water to a growing crop."

In addition to the manure control options, the field day will include information on manure production and nutrient content of feedlot manure, how to sample manure for nutrient analysis, stockpiling regulations, a review of manure control practices, and an update on rules for medium-sized operations.

The ISU Armstrong Research Farm is located at 53020 Hitchcock Ave., Lewis, IA, 11 miles east of Oakland or 11 miles west of Atlantic on Hwy 6, then half mile south on 525th Street (M53) and half-mile east on Hitchcock Ave. Contact Kohl at 712-732-5056 for more information.
