Some of the biofuel plants such as jatropha and switchgrass grow nicely on marginal land which is not adequate for food production. It might be possible to produce a lot of biofuel while taking over no existing agricultural land. Switchgrass is a feedstock for ethanol. I don't know if ethanol could be blended into jet fuel. Switchgrass is a very promising plant as it greatly improves the land on which it grows and sequesters a significant amount of carbon. Approximately 80% of its mass is below ground in its extensive root system.
