Soil Chemistry from Deep Cores- GLBRC Intensive Site
Deep core soil samples 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 and University of Wisconsin Soils Laboratory .
This datatable is part of the GLBRC Deep Core Soil Surveys dataset. The GLBRC periodically (presently every 5 years) collects and analyzes deep soil cores for the GLBR Intensive Sites and the GLBRC Scale-up sites. Soil is sampled to a depth of one meter, and analyzed at various depths for bulk density, texture, moisture, and carbon and nitrogen content. Soil horizons are also identified.
