Residual Stover Biomass — GLBRC Biofuel Cropping System 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Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use
Biomass of stover residue left on the ground after harvesting of corn stover in BCSE annual treatments (G1-G4, depending on year) from 2015 onward. Note that windrowing of stover began in 2015 and results in uneven distribution on the ground; samples are hand-collected within windrows (W) and between (B) windrows and weighed separately as within (SW) and between (SB) stover biomass. Data from 2008-2014, when harvest resulted in an even distribution of stover on the ground, are found in datatable GLBRC081-004.
This datatable is part of the Agronomic Yields dataset.
This dataset contains the yields from machine harvests for all treatments (G1-G10) of the GLBRC Biofuel Cropping System Experiment (BCSE). Yields are measured in each treatment replicate (R1-R5) during normal crop harvest by machine harvesters appropriate to each crop, as recorded in the KBS Aglog.
This dataset also includes yields from two different subplot studies on 1) stover removal vs stover non-removal and 2) plus nitrogen vs no nitrogen fertilization. See the BCSE – Sampling protocol for further description of subplot management and location.
