Agronomic Soil Chemistry - KBS Scaleup sites

Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use

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 Scaleup Soil Properties dataset. Soil properties measured on the GLBRC scaleup sites
