Soil Chemistry from Deep and Surface Soil Cores- Marginal Sites — GLBRC Marginal Land 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Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use
Deep core soil samples and surface samples are taken occasionally for fertilizer recommendations and analyzed for pH, lime index, phosphorus, potassium, calcium, magnesium, cation exchange capacity and organic matter.
KBS samples are analyzed by the Michigan State University Soil and Plant Nutrient Laboratory.
This datatable is part of the Marginal Land Experiment dataset.
