Dry Matter Yield — GLBRC Scale-up 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Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use

Dry matter yields from machine harvest of fields at Lux Arbor Reserve and the Marshall Farm. Note that 1) corn and soybean grain are reported as dry weight (not at standard moisture content); 2) all yields are reported in megagrams dry matter per hectare; and 3) removal of corn stover from fields began with the 2015 harvest.

This datatable is part of the Cropping Systems — GLBRC Scale-up Experiment dataset. Data on plant communities in fields at Lux Arbor Reserve (L1-L3) and Marshall Farm (M1-M4) planted to corn (L1, M1), switchgrass (L2, M3), and restored prairie (L3, M2) in 2010 after a 2009 no-till soybean crop in all fields to convert tilled corn-soybean-wheat rotations (AGR) at Lux Arbor and fields in the Conservation Reserve Program (CRP) at Marshall Farm to no-till bioenergy crops. One field at Marshall Farm (M4) remains as CRP brome grass to serve as a reference.
