Biorenewable energy: new opportunities for grassland agriculture

摘要：

Biofuels represent a significant challenge and opportunity for grassland agriculture.Producing liquid fuels from cellulosic biomass affords a number of potential environmental benefits.Biofuels result in lower greenhouse gas emissions than fuels derived from petroleum.Growing perennial biomass crops reduces soil erosion and sequesters more carbon than annual crops grown for grain or biomass.Low energy density of biomass will require high yield density to lower transportation costs.Corn and sorghum are crops that have high near‐term potential as annual biomass crops.Switchgrass and Miscanthus are perennial species that have been broadly evaluated as potential biomass crops, but will benefit from further development for widespread use.New crops and cropping systems developed specifically for bioenergy production will be necessary to meet biofuel production targets.Bioenergy crops should be developed that use inputs efficiently, have high and stable productivity, have positive environment impact, and are compatible with existing cropping systems.
