Agronomic Soil Chemistry — Main Cropping System Experiment (MCSE)
Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use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 chemistry of surface (0-25 cm) samples collected annually for MCSE Treatments 1-4 and 6 (since 1992), on a near annual basis for Treatments 5, 7 and 8, and less frequently for the unmanaged sites (TCF, TDF and TCF).
This datatable is part of the Agronomic Soil Chemistry dataset.
Soil samples are typically collected in the fall and sent to an analytical laboratory for nutrient analysis and for fertilizer and liming recommendations for the following spring. Analyses include pH, cation exchange capacity, lime index, phosphorus, potassium, calcium, magnesium, zinc, sulfur, and boron.
