Cellulosic feedstock projects are beginning to scale in size and frequency. An example of this is the 1,000 acre switchgrass plot in Oklahoma, now in its second year. The project is led by the Ardmore-based Noble Foundation, and strands are reaching 3 ft in height.
Unlike corn, switchgrass doesn’t need to be replanted each year. It also takes less tractor-fuel and fertilizer to produce, can be grown on marginal land and doesn’t require as much water.
