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Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use

Corn stover (dried stalks and leaves remaining after grain harvest) and cover crop yields, expressed as dry matter, for BCSE annual treatments (G1-G4, depending on year). Note that from 2008-2014, stover was harvested by mowing and chopping directly into a forage wagon and that from 2015 onward, it is mowed, windrowed, and baled.

Also included is the biomass of hand-collected samples of residual corn stover—the stover biomass that remains on the ground after stover harvest—for the period 2008-2014 when harvest resulted in an even distribution of stover on the ground. The change to windrowing in 2015 resulted in an uneven distribution of stover on the ground and requires a different sampling approach; these data are located in datatable GLBRC143-002.

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.
