Whole plant carbon and nitrogen

GLBRC130:Whole plant carbon and nitrogen

In 2017 at the GLBRC BCSE plots, above- and belowground plant biomass were sampled at maturity near- and post-machine harvest time, respectively. All samples were collected from all treatments (G1-G10), Blocks 2 through 4. The overarching goal of this project is to determine any differences on above- and belowground biomass production between annual and perennial crops dedicated to bioenergy production after ten years of establishment.


GLBRC130-001 Root Carbon and Nitrogen
Total Carbon and Nitrogen values from the Root Harvest Campaign. The samples from some plots and depths did not have enough material to complete the grinding - pulverization - CN packing procedure.
GLBRC130-002 Above ground Plant Carbon and Nitrogen from the root excavation project
GLBRC130-003 Root biomass
Root biomass sampled with deep coring and pit excavations. Samples were taken on top of, and between plants and as part of the soil excavation. The deep core samples were taken within the perimeter of the pit. In this data table the biomass from the core samples has already been added to the pit biomass.
GLBRC130-004 Aboveground biomass at the time of root sampling
Aboveground biomass was sampled at the same time the root samples were taken. In the G1, G2, G3, and G4 plots, we sampled one plant and assumed that the area that it represents is 45.5 cm^2.
