The "Upper Midwest Tillage Guide" is a regional resource for crop producers and advisers interested in reducing tillage, but who may not feel comfortable choosing the best options for a specific operation. The 40-page guide lays out the benefits of various equipment types and tillage options in four chapters that may be read consecutively or individually. A collaboration between the University of Minnesota Extension and North Dakota State University, the guide's authors are Jodi DeJong-Hughes, U of M Extension; and Aaron Daigh, NDSU soil scientist.
