There is considerable uncertainty about how rates of soil carbon (C) and nitrogen (N) cycling
will change as CO2 accumulates in the Earth's atmosphere. We summarized data from 47 …

Elevated atmospheric CO2 has the potential to increase the production and alter the
chemistry of organic substrates entering soil from plant production, the magnitude of which is …

Direct effects of increased above‐ground CO2 concentration on soil microbial processes are
unlikely, due to the high pCO2 of the soil atmosphere in most terrestrial ecosystems …

Elevated CO2 increases root growth and fine (diam.[les] 2 mm) root growth across a range of
species and experimental conditions. However, there is no clear evidence that elevated …

Atmospheric CO 2 concentrations can influence ecosystem carbon storage through net
primary production (NPP), soil carbon storage, or both. In assessing the potential for carbon …

Monoliths of two contrasting vegetation types, a species-rich grassland on a brown earth soil
over limestone and a species-poor community on a peaty gley, were transferred to …

It is uncertain whether elevated atmospheric CO 2 will increase C storage in terrestrial
ecosystems without concomitant increases in plant access to N. Elevated CO 2 may alter …

Experimental evidence from a diverse set of forested ecosystems indicates that CO2
enrichment may lead to deeper rooting distributions. While the causes of greater root …

We tested a conceptual model describing the influence of elevated atmospheric CO 2 on
plant production, soil microorganisms, and the cycling of C and N in the plant-soil system …

Rising atmospheric CO2 and temperatures are probably altering ecosystem carbon cycling,
causing both positive and negative feedbacks to climate. Below‐ground processes play a …
