Abstract

While it is true that a significant, growing minority of Iowa farmers are successfully adopting low-input systems such as ridge till— and are profiting as a result—the vast majority of Iowa farmers continue to practice conventional, chemically intensive methods. Moreover, there exists a counter-trend in Corn Belt agriculture toward no-till systems. While notill systems conserve soil resources, they often require more fertilizer and herbicides.
