Cornbelt Cow-Calf Conference
Iowa Beef Center
The Cornbelt Cow-Calf Conference is one of the longest running and most successful conferences of its type in the Midwest. For over forty years, the conference has provided an opportunity for producers, researchers, and over 70 industry representatives to come together to explore current topics and issues. This concentrated one-day conference focuses on management and production practices that contribute to making the cow-calf business profitable and competitive on a long-term basis.

Abstract

In 2006, the Iowa DNR identified 336 impaired water bodies in Iowa. The majority of these impairments are associated with elevated nutrient, sediment, or bacterial loads in streams and lakes. Poorly managed grazing of beef cattle in riparian areas may contribute to a reduction in quality of Midwest surface waters. However, research has shown that management practices that alter the timing, frequency, duration, and timing of grazing can reduce the impact of cattle on water sources.
