This study was conducted in a corn field of a research farm in Franklin County, central Ohio. Some sites within the field have experienced water-induced soil erosion following heavy rainstorms. Physical characteristics of the soil were compared between eroded (ER) and un-eroded sites (UN). Compared with ER, the soil in UN had lower penetration resistance, bulk density and sand content, and higher shear strength, hydraulic conductivity, intrinsic permeability, and contents of soil organic carbon, total nitrogen, clay, silt, and very fine sand. The erodibility factor (K) was lower in UN than in ER. Hence, it is suggested the ER sites within the corn field agroecosystem are more susceptible to accelerated erosion as compared with UN sites
