Agronomic Yield- GLBRC scaleup
Agronomic yield from the KBS GLBRC Scale-up fields at Lux Arbor Reserve and the Marshall Farm. Treatments were first applied in 2010; all fields were planted with soy in 2009. Stover was first harvested in 2015 and previously was not removed from M1 or L1.
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.
