Stover and Residual Stover Biomass and Cover Crop Yield — 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Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use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 residual corn stover (remaining biomass after machine harvest of stover) dry matter yield are given here for KBS and Arlington GLBRC Biofuel Cropping System Experiment treatments G1-G4. Microplots were established to determine the efficacy of the stover harvesting machinery.
Cover crops were added to treatments G2-G4 in 2013. Cover crop yield is also given in the data table.
Starting in 2015 stover residue was windrowed and is reported in https://data.sustainability.glbrc.org/datatables/718
This datatable is part of the GLBRC Agronomic Yields dataset. This data set contains information about agronomic yields for the GLBRC Biofuel Cropping System Experiment, the Stover Removal Experiment and the Unfertilized/fertilized Experiment at Kellogg Biological Station and Arlington and also for the GLBRC Scale-up experiment and Switchgrass N-rate experiments at KBS. Perennial treatments include herbaceous perennials- switchgrass, miscanthus, grass mix, old field and prairie (G5,G6, G7, G9 and G10) and poplar trees (G8) . Annual treatments include continuous corn (G1), and during 2008-2011 corn-soybean–canola rotations (G2-G4). In 2012 ,G2-G4 treatments no longer planted canola and added cover crops to a corn-soy rotation. Agronomic yields are measured during normal crop harvest by machine harvesters appropriate to each crop as described in the GLBRC Agronomic Protocol.
