Soil Total Carbon and Nitrogen — GLBRC Scale-up Experiment

Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use

Total carbon and nitrogen content of surface and deep core samples from fields of the GLBRC Scale-up Experiment. A dried subsample is ground and analyzed for carbon and nitrogen content, reported as a percentage.

This datatable is part of the Soil Properties — KBS GLBRC Scale-up Experiment dataset.

Soil properties of fields at Lux Arbor Reserve (L1-L3) and Marshall Farm (M1-M4) planted to corn (L1, M1), switchgrass (L2, M3), and restored prairie (L3, M2) in 2010 after a 2009 no-till soybean crop in all fields to convert tilled corn-soybean-wheat rotations (AGR) at Lux Arbor and fields in the Conservation Reserve Program (CRP) at Marshall Farm to no-till bioenergy crops. One field at Marshall Farm (M4) remained as CRP brome grass to serve as a reference. Each field has 10 sampling stations (S1-S10) around which most soil sampling occurs.
