Technical Abstract: Changes in soil respiration due to rising atmospheric CO2 have large implications for land-atmosphere carbon balance and consequently the greenhouse effect. Here we report results from prairie exposed to a gradient of CO2 spanning from preindustrial (250ppm) levels to levels expected mid-century (500ppm). The experiment consists of an array of prairie plots housed in two plastic-covered tunnels. Three soil types are represented throughout the CO2 gradient: Austin (mollisol), Bastrop (vertisol), and Houston (alfisol). The experiment has completed its second year of CO2 treatment.
