LTAR baseline soil test results
This datatable is part of the Agronomic Soil Test Results dataset. Soil samples are taken annually (usually in the Fall) for fertilizer recommendations and analyzed by the Michigan State University Soils Laboratory. The soil samples are taken from the annual treatments T1 though T4 and T6.
