Agronomic Soil Chemistry from Deep and Surface Soil Cores- Rainfall Exclusion Experiment at Marginal Land Sites (MLE)
Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use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, in the Wisconsin samples, organic matter.
KBS samples are analyzed by the Michigan State University Soil and Plant Nutrient Laboratory and University of Wisconsin Soils Laboratory .
This datatable is part of the MLE – Rainfall Exclusion Experiment dataset. This dataset contains data from Rainfall Exclusion Experiment at Marginal Land Sites. The purpose of the experiment is to learn the drought effects on switchgrass. Data in this dataset can also be found in the dataset of Marginal Land Experiment.
