Farmers in Nebraska and the Dakotas brought the U.S. closer to becoming a biofuel economy, planting huge tracts of land for the first time
with switchgrass — a native North American perennial grass (Panicum virgatum) that often grows on the borders of cropland naturally — and proving that it can deliver more than five times more energy than it takes to grow it.
«What we saw
with switchgrass is that you're actually storing carbon in the soil,» he said.
Plastic containers, each filled with about 5.5 pounds of soil, were planted
with switchgrass (Panicum virgatum) seeds.
«
With switchgrass, for example, frequently you can not harvest the first year's crop because it takes a long time for the root system to establish,» says study author Philip Benfey, a professor of biology at Duke University and director of Duke's Institute for Genome Sciences and Policy Center for Systems Biology.

It seems Ma Nature has got a beef
with biofuels and has tossed a wrench into the biofuel industry in the form a virus that impacts the feedstocks —
switchgrass in particular.
The next generation of bioenergy technology aims to replace current feedstocks such as corn, sorghum, sugarcane, rapeseed, soy, and oil palm
with dedicated cellulosic crops (Kszos et al. 2000; Heaton et al. 2008b), such as woody tree species and the grasses
switchgrass (Panacum vergatum) and miscanthus (Miscanthus x giganteus)(Lewandowski et al. 2000).
Though the current substitution rate is negligible, a rapid expansion is possible
with the use of wood residues (urban wood, pallets, and secondary manufacturing products) and dedicated feedstock supply systems (DFSS) such as willow, poplar, and
switchgrass.
