             abstract = "Sustainable bioenergy production depends upon the efficiency with 
                         which crops use available water to produce biomass and store 
                         carbon belowground. Therefore, water use efficiency (WUE; 
                         productivity vs. annual evapotranspiration, ET) is a key metric of 
                         bioenergy crop performance. We evaluate WUE of three potential 
                         perennial grass bioenergy crops, Miscanthusxgiganteus 
                         (miscanthus), Panicum virgatum (switchgrass), and an assemblage of 
                         prairie species (28 species), and Zea mays-Glycine max rotation, 
                         during the establishment phase in Illinois. Ecosystem WUE (EWUE; 
                         net ecosystem productivity vs. ET) was highest in miscanthus, 
                         reaching a maximum value of 12.80.3kgha(-1)mm(-1) in the third 
                         year, followed by switchgrass (7.50.3kgha(-1)mm(-1)) and prairie 
                         (3.90.3kgha(-1)mm(-1)); the row crop was the lowest. Besides EWUE, 
                         harvest-WUE (HWUE, harvested biomass vs. ET) and net biome 
                         productivity-WUE (BWUE, calculated as net ecosystem production - 
                         harvest vs. ET) were also estimated for all crops and years. After 
                         three years of establishment, HWUE and BWUE were highest in 
                         miscanthus (9.02 and 3.8 +/- 2.9kgha(-1)mm(-1), respectively) 
                         providing a net benefit to the carbon balance, while the row crops 
                         had a negative carbon balance and a negative BWUE. BWUE for 
                         maize/soybean indicate that this ecosystem would deplete the soil 
                         carbon stocks while using the water resources. Switchgrass had the 
                         second highest BWUE, while prairie was almost neutral indicating 
                         that long-term carbon sequestration for this agro-ecosystem would 
                         be sensitive to harvest timing with an early harvest removing more 
                         biomass, and thus carbon, from the field.",
