Dry Matter Yield — GLBRC Marginal Land Experiment
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.
