The aim of this research was to determine the soil erosion rates in cropland of west central Illinois Spoon River Valley) using a magnetic tracer (fly ash) and radio-cesium (cesium-137). The fly ash and cesium-137 accumulation on a stable cropland/hayland summit was determined using a spiral transect. This reference site was used as a baseline and then compared with the fly ash and cesium-137 levels in adjacent cropland landscape positions to estimate loss from erosion. The amount and rate of erosion predicted for each cropland landscape position using the fly ash and cesium-137 methods were determine for the 1910 to 1960, 1960 to 2009 and for the entire 100-year time periods. It is showed that the highest predicted cropland erosion rates were on the backslope; The erosion rates were above the tolerable soil loss rate for Hickory soils; The erosion rates are higher for the 50 years after 1960 than before due to continued use of moldboard plowing and more intensive corn–soybean rotation
