Soil Total Carbon and Nitrogen — GLBRC Marginal Land 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Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use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 deep core soil samples (1 meter deep core split in 4 depths) from the Marginal Land Experiment.
This datatable is part of the Soil Properties — Marginal Land Experiment dataset.
This dataset contains soil data for the GLBRC Marginal Land Experiment (MLE) originally established in 2013 at north, central and south sites in Wisconsin and Michigan. The experiment consists of six different biofuel cropping systems (a.k.a. treatments; G5-G10; including switchgrass, miscanthus, native grasses, hybrid poplar, early successional, and restored prairie, respectively) plus an historical vegetation control (G11), replicated in each of 4 blocks (R1-R4) at each site. Split-plot treatments were initiated in 2014-2016 to examine the effect of nitrogen fertilization [plus_n (+N) vs control (0N)] on all cropping systems.
