agronomic soil chemistry (deep core) — 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Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use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 (to 1 m) and surface (typically 0-25 cm) soil samples are taken periodically and sent to an analytical laboratory for fertilizer/liming recommendations and analyzed for pH, lime index, phosphorus, potassium, calcium, magnesium, cation exchange capacity and, depending on laboratory, organic matter.
From 2012-2022, samples were analyzed by either the Michigan State University Soil and Plant Nutrient Laboratory or the University of Wisconsin Soils Laboratory, which included organic matter in their analyses.
This datatable is part of the Data for Delipa et.al dataset.
