Technical Abstract: Patterns of soil erosion vary across the landscape especially for agricultural areas where different management strategies are use to minimize water, wind, and tillage erosion that tend to redistribute soils. This study used fallout Cs-137 to determine rates and patterns of soil redistribution on 19 first order research watersheds at the USDA ARS North Appalachian Experimental Watershed (NAEW) at Coshocton, Ohio. These small watersheds have been managed and monitored since 1935. Management practices include conventional tillage, no-tillage, managed pasture, natural meadows, and combinations of these management practices. Soil erosion rates differed significantly between management practices with natural meadows having the lowest soil erosion rates followed by pastures, no-tillage and conventional tillage. These studies show the impact of soil redistribution patterns within small watersheds between management practices, and aid in understanding soil erosion patterns and identifying sources of sediment related to management practices.
