Native grasses build soil fertility

This news is very important to the food vs. fuel debate. A new study lends support to the idea that native grasses can improve the soil while providing biomass for biofuel production at the same time. Soils currently too exhausted for food production could be restored while providing biofuel feedstocks. With a long-term rotation, these soild could then be returned to food production. This would end the food vs fuel debate, and in fact would mean more biofuel production equals more food in the long run.
