A recent study concluded that 50 million U.S. acres of cropland and pasture could be used for the production of perennial grasses, such as switchgrass, for biofuel feedstock. Economically viable production of a perennial grass monoculture from which substantial quantities of biomass are removed annually is expected to require nitrogen fertilizer.
