C Factors for No-Till and Reduced-Till Corn

ABSTRACT CROPPING and management (C) values for use in the Universal Soil Loss Equation were derived by crop stage and annual periods for no-till corn grown for silage or grain, and for reduced-till corn grown for grain. The low C-values as compared to those for conventional-till corn for silage and grain reflected the soil erosion control benefits of no-till and reduced-till corn. The C-values measured for all treatments were much lower than those previously accepted.
