Unfertilized/Fertilized Yield Experiment — 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Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use

Subplots were established on the perennial crops to examine fertilization’s effects on yield. Treatments G5, G6, G7, G8, and G9 are fertilized, so the subplot was unfertilized; G10 does not receive fertilizer, so the G10 subplot was fertilized.

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.
