Impacts of Beef Cattle–Grazing Systems on Cattle Distribution and Streambank Erosion
Many of Iowa’s surface waters contain high sediment and phosphorus(P) concentrations. It is recognized that overgrazing along pasture streams may result in soil erosion and manure deposition that contribute to P loading of pasture streams. Little research has evaluated the effects of grazing management on sediment and P loading of pasture streams in the Midwest, but grazing management is still generally considered to limit sediment and P loading of pasture streams. The objective of this study was to measure the effects of beef cattle– grazing systems on the spatial and temporal distribution patterns of cattle, the resulting impacts on selected pasture characteristics, and streambank erosion from pasture streams.
