Summary After a step increase in the atmospheric partial pressure of CO 2 (pCO 2 ), the availability of mineral N may be insufficient to meet the plant's increased demand for N. Over time, however, the ecosystem may adapt to the new conditions, and a new equilibrium may be established in the fluxes of C and N. This would result in a higher dry mass (DM) yield response of the plants to elevated pCO 2 . The effect of elevated at...
