The capability of terrestrial ecosystems to sequester carbon (C) plays a critical role in regulating future climatic change yet depends on nitrogen (N) availability. To predict long-term ecosystem C storage, it is essential to examine whether soil N becomes progressively limiting as C and N are sequestered in long-lived plant biomass and soil organic matter. A critical parameter to indicate the long-term progressive N limitation (PNL) is net change in ecosystem N content in association with C…

Cumulative response of ecosystem carbon and nitrogen stocks to chronic CO2 exposure in a subtropical oak woodland

These findings challenge the treatment of terrestrial ecosystems responses to elevated CO2 in current biogeochemical models, where the effect of elevatedCO2 on ecosystem C balance is described as enhanced photosynthesis and plant growth with decomposition as a first-order response.

Effects of elevated CO 2 and N fertilization on plant and soil carbon pools of managed grasslands: a meta-analysis

Abstract. Elevated atmospheric CO2 levels and increasing nitrogen deposition both stimulate plant production in terrestrial ecosystems. Moreover, nitrogen deposition could alleviate an increasing

A scrub-oak woodland has maintained higher aboveground biomass accumulation after 11 years of atmospheric CO2 enrichment (ambient 1350lmolCO2mol � 1 ), despite the expectation of strong nitrogen (N)

Soil carbon and nitrogen cycling and storage throughout the soil profile in a sweetgum plantation after 11 years of CO 2-enrichment

Increased partitioning of carbon (C) to fine roots under elevated [CO2], especially deep in the soil profile, could alter soil C and nitrogen (N) cycling in forests. After more than 11 years of

Progressive N limitation of plant response to elevated CO2: a microbiological perspective

Examination of experimental results that examined elevated CO2 effects on microbial parameters shows that increased C inputs dominate the CO2 impact on microbes, microbial activities and their subsequent controls over ecosystem N dynamics, potentially enhancing microbial N acquisition and ecosystem N retention.

Nitrogen accumulation, rather than carbon: nitrogen stoichiometric variation, underlies carbon storage during forest succession

Forest ecosystems play an important role in regulating global temperatures through their capability to take up and store CO2 from the atmosphere, but the magnitude and sustainability of this carbon

Processes regulating progressive nitrogen limitation under elevated carbon dioxide: A meta-analysis

Abstract. The nitrogen (N) cycle has the potential to regulate climate change through its influence on carbon (C) sequestration. Although extensive research has explored whether or not progressive N

Soil [N] modulates soil C cycling in CO2-fumigated tree stands: a meta-analysis.

The 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.

Progressive Nitrogen Limitation of Ecosystem Responses to Rising Atmospheric Carbon Dioxide

Abstract A highly controversial issue in global biogeochemistry is the regulation of terrestrial carbon (C) sequestration by soil nitrogen (N) availability. This controversy translates into great

Elevated atmospheric CO2, fine roots and the response of soil microorganisms: a review and hypothesis

There are insufficient data to predict how microbial activity and rates of soil C and N cycling will change as the atmospheric CO 2 concentration continues to rise, and it is argued that current gaps in understanding of fine-root biology limit the ability to predict the response of soil microorganisms to rising atmosphericCO 2.

Soil nitrogen cycling under elevated CO2: A synthesis of forest face experiments

The extent to which greater net primary productivity (NPP) will be sustained as the atmospheric CO2 concentration increases will depend, in part, on the long-term supply of N for plant growth. Over a

Limited carbon storage in soil and litter of experimental forest plots under increased atmospheric CO2

A significant accumulation of carbon is reported in the litter layer of experimental forest plots after three years of growth at increased CO2 concentrations, suggesting that significant, long-term net carbon sequestration in forest soils is unlikely.

Plant diversity enhances ecosystem responses to elevated CO2 and nitrogen deposition

It is found that the enhanced biomass accumulation in response to elevated levels of CO2 or nitrogen, or their combination, is less in species-poor than inspecies-rich assemblages.

It is indicated that increased CO2 can alter the interaction between plants and microbes in favour of plant utilization of nitrogen, thereby slowing microbial decomposition and increasing ecosystem carbon accumulation.

Soil fertility limits carbon sequestration by forest ecosystems in a CO2-enriched atmosphere

Evidence is presented that estimates of increases in carbon sequestration of forests, which is expected to partially compensate for increasing CO2 in the atmosphere, are unduly optimistic and that fertility can restrain the response of woodcarbon sequestration to increased atmospheric CO2.
