GLBRC Sustainability Data Catalog

Agronomic Soil Chemistry - KBS Scaleup sites

Soil samples are taken annually (usually in the Fall) 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 GLBRC soil properties dataset. Soil measurements from GLBRC experiments.
