Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use

Soil samples taken for fertilizer recommendations. Samples are collected from the LTER Main Site, treatments 1-4 and 6 and analyzed for pH, CEC, phosphorous and potassium.

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.
