Dry Matter Yield — GLBRC Marginal Land 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Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use
Agronomic yields from machine harvest of the Marginal Land Experiment at sites in Michigan and Wisconsin. Yield data is given for 6 treatments (switchgrass, miscanthus, native grasses, early succession, restored prairie and historical vegetation) on the 6 Marginal Land Experiment sites (Wisconsin South – Oregon site was retired after 2018 growing season). Note that the historical vegetation (G11) treatment is not machine harvested; agronomic yield is estimated by hand harvesting. Yield data are given as dry matter expressed as Mg/ha.
G11 was hand harvested at 3 stations per split plot from 2015-2017 and at 2 stations per split plot beginning in 2018. The average harvest per split plot is given here. Raw data is available on request.
