Soil Test Lab Analyses - Agronomic — GLBRC Biodiversity Experiment
Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use
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.
