Chemical analyses of soils taken from Michigan Extensive sites of the GLBRC Biofuel Biodiversity Study and analyzed by the Michigan State University Soils Laboratory.

This datatable is part of the Michigan GLBRC Extensive Sites dataset. The Great Lakes Bioenergy Research Center’s (GLBRC) Extensive Sites are farm-scale fields located on working farms. Fields of corn, switchgrass, and restored prairie are represented at each of 10 locations in 13 counties in Michigan.
