LEWIS, Iowa – Stressed pastures and high grain markets continue to limit forage productivity and land access for cattlemen. Many producers have turned toward integrating cover crops as an alternative to extend the grazing season, and some have even begun utilizing warm season annual forages to fill some voids during the summer slump. 
Iowa State University Extension and Outreach and the Armstrong Memorial Research and Demonstration Farm will host a field day featuring ongoing forage research with summer annuals. The event will take place Tuesday evening, July 12, at the Wallace Learning Center on the research farm near Lewis.
The field day will start with a classroom session featuring swath grazing of warm season annuals as a winter feeding strategy. Head researcher Garland Dahlke of the Iowa Beef Center will discuss forage quality and utilization, and the challenges and successes of using pearl millet, forage sorghum and sorghum sudangrass for swath grazing in Iowa.
Attendees will have the opportunity to view summer annual test plots at the farm including German millet, pearl millet, sorghum sudangrass, sudangrass and teff. Warm season species selection, farm usage and application, forage nutrient value and anti-quality issues also are on the agenda.
Registration and a light meal begin at 5:30 p.m., and the program runs from 6-8 p.m. Other presenters are ISU Extension and Outreach Field Agronomist Aaron Sauegling and Beef Specialist Erika Lundy-Woolfolk. See more details on the field day flyer.
The field day is free thanks to grants from the North Central Extension Risk Management Education Center and the Southern Iowa Forage and Livestock Committee. To ensure adequate meal count, preregister by July 8 by calling the ISU Extension and Outreach Cass County office at 712-243-1132.
