Modeling Sediment Deposition Behind Corn Residue
ABSTRACT Asimulation model was developed to predict the amount of sediment deposited behind corn residue in row middle areas. Data generated in a rainfall simulator field study were used for model validation. Observed soil erosion rates compared favorably with ero-sion rates predicted by the model. The results generated by the simulation model indicate that, although dif-ferences in soils can change crop residues' effect on soil losses, more influence is exerted by differences in slope steepness. As slope steepness increases, crop residues are less effective in controlling soil erosion.
