Patrick,

Thank you for your question! The best resource to use while researching the different types of soil found in Michigan is the USDA Natural Resources Conservation Service or NRCS. Specifically, you will want to review their Web Soil Survey tool found here:

For a more concise resource, you may review the information produced by MSU at the following web page:
