Plant Total Carbon and Nitrogen — GLBRC Scale-up Experiment
Total carbon and nitrogen content of plants of the GLBRC Scale-up Experiment. Dried and ground subsamples of peak biomass samples are analyzed and include: 1) corn stems and grain at each sampling station in fields L1 and M1; 2) switchgrass, an aggregate of additional species, and surface litter, combined across stations, in fields L2 and M3; and 3) separate analysis of the top 3 species by weight, an aggregate of the remaining species, and surface litter, combined across stations, in fields L3, M2, and M4. Subsamples from soybean harvest in 2009 and occasional post-harvest residue collections are also included.
This datatable is part of the GLBRC Scale-up Experiment Cropping Systems dataset.
This dataset contains data on plant communities in 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) remains as CRP brome grass to serve as a reference. Each field has 10 sampling stations (S1-S10) around which most sampling occurs.
