Final report of a project which exposed native tallgrass prairie to twice-ambient atmospheric CO{sub 2}. Improved water use efficiency increased biomass production and increased soil organic matter. Twice ambient CO{sub 2} decreased canopy evapotranspiration by 22%, but, maintained an increased net carbon sequestration
