Perennial biomass from grasslands managed for conservation of soil and biodiversity can be harvested for bioenergy. Until now, the quantity and quality of harvestable biomass from conservation grasslands in Minnesota, USA, was not known, and the factors that affect bioenergy potential from these systems have not been identified. We measured biomass yield,(More)
Various local factors influence the decision of when to harvest grassland biomass for renewable energy including climate, plant composition, and phenological stage. However, research on biomass yield and quality related to a wide range of harvest timing from multiple environments and years is lacking. Our objective was to determine the effect of harvest(More)
Native prairie plants can be managed to provide biomass for cellulosic ethanol production; however, there is inadequate information in northern latitudes regarding the effects of fertilizers on biomass and ethanol yields. We evaluated biomass yield, land ethanol yield (theoretical ethanol production per unit area), and nutrient harvest in grasslands managed(More)
Companion crops supply additional economic returns when used to establish perennial forage crops, and they should provide similar benefits when establishing native perennial grasslands for bioenergy. We evaluated the effect of cereal grains and native perennial companion crops on biomass yield of three different bioenergy crop types (switchgrass (Panicum(More)
