•Extra stored soil carbon was lost again seven years after FACE termination.•Increased soil carbon during FACE stimulated the decomposition of old soil carbon.•Large transfer of nitrogen from deeper soil layers upon increasing plant demand.•Soil carbon and nitrogen pools in this ecosystem are highly...
