Peak Biomass — 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Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use

Peak above-ground biomass of plant communities in fields at Lux Arbor Reserve and Marshall Farm. Plants are hand-harvested within a quadrat and sorted to species; the residual dead plant material left on the soil surface after hand-harvest is collected and saved as “surface litter”. Peak biomass measurements are used as estimates of above-ground net primary production (ANPP); for machine harvested yields, see http://data.sustainability.glbrc.org/datatables/267. Note that 1) peak biomass sampling was discontinued after the 2016 growing season and 2) samples may also be analyzed for total carbon and nitrogen and archived.

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.
