Soil Test data — 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Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use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 samples are taken annually (usually in the Fall) for fertilizer recommendations and analyzed by the Michigan State University Soils Laboratory. The soil samples are taken from the annual treatments T1 through T4. The sample protocols are available from the soil test lab.
This datatable is part of the MCSE Model input data dataset.
Consolidated dataset for the ARDEN crop modeling effort. This pulls together several useful data tables into one dataset. Further information can be found at https://agmip.github.io/ARDN/
