abstract = {Under elevated atmospheric CO(2) concentrations, soil
carbon (C) inputs are typically enhanced, suggesting larger
soil C sequestration potential. However, soil C losses also
increase and progressive nitrogen (N) limitation to plant
growth may reduce the CO(2) effect on soil C inputs with
time. We compiled a data set from 131 manipulation
experiments, and used meta-analysis to test the hypotheses
that: (1) elevated atmospheric CO(2) stimulates soil C
inputs more than C losses, resulting in increasing soil C
stocks; and (2) that these responses are modulated by N. Our
results confirm that elevated CO(2) induces a C allocation
shift towards below-ground biomass compartments. However,
the increased soil C inputs were offset by increased
heterotrophic respiration (Rh), such that soil C content was
not affected by elevated CO(2). Soil N concentration
strongly interacted with CO(2) fumigation: the effect of
elevated CO(2) on fine root biomass and -production and on
microbial activity increased with increasing soil N
concentration, while the effect on soil C content decreased
with increasing soil N concentration. These results suggest
that both plant growth and microbial activity responses to
elevated CO(2) are modulated by N availability, and that it
is essential to account for soil N concentration in C
cycling analyses.},
