It was good timing then for the website! Check these sections out especially…
This is a nifty set of pamphlets the NRCS put together…
University of Wisconsin did these, here’s a link to all sections which are formulated for the Midwest, especially Wisconsin/Michigan along the lakeshore. You should be able to download all the info. They changed it slightly in the 2 years since I initially found it – but all the info should be there.
