In two nested global change experiments, nitrogen (N) and soil moisture jointly constrained the response of biomass production to elevated CO2 over the long term. When both water and N were limited, elevated CO2 did not affect plant biomass. When neither resource was limited, elevated CO2 caused an increase in plant biomass.
