Can you give me some resources for crop rotations in Wisconsin?

Thank you for contacting ATTRA for information on crop rotation. The following resources should be helpful to you. First of all, here is a good website from UW Extension on rotations prior to 1940 (pre-herbicide era). The article contrasts the historical rotation with the more typical rotation of corn and soybeans used today. http://corn.agronomy.wisc.edu/Library/L001.aspxAlso, we just received a new book in our office titled Crop Rotation on Organic Farms: A Planning Manual Here is a link to the site to order. http://www.sare.org/publications/croprotation.htm. This book is most applicable to the northeast part of the US, but Wisconsin would have a similar enough climate that it would be applicable.North Dakota State has a good link on designing rotation in North Dakota. The far eastern part of the state would be the region most similar to yours and would probably work as well. http://www.ag.ndsu.edu/pubs/plantsci/crops/eb48-3.htm. Another one from NDSU is located here: http://www.ag.ndsu.edu/pubs/plantsci/crops/eb48-1.htm Also, here is a link on rotations from an excerpt of Managing Soils for Better Crops http://www.sare.org/publications/bsbc/chap11.htm
