Journal ArticleDOI
Separating root and soil microbial contributions to soil respiration: A review of methods and observations
TL;DR: In this article, three primary methods have been used to distinguish hetero- versus autotrophic soil respiration including integration of components contributing to in situ forest soil CO2 efflux (i.e., litter, roots, soil), comparison of soils with and without root exclusion, and application of stable or radioactive isotope methods.
Journal ArticleDOI
Soil respiration and the global carbon cycle
TL;DR: In this paper, the authors provide a brief review for policymakers who are concerned that changes in soil respiration may contribute to the rise in CO2 in Earth's atmosphere, while simultaneously leaving a greater store of carbon in the soil.
Journal ArticleDOI
Net primary production of a forest ecosystem with experimental CO2 enrichment

TL;DR: The response of this young, rapidly growing forest to carbon dioxide may represent the upper limit for forest carbon sequestration.
Journal ArticleDOI
Soil CO2 dynamics, acidification, and chemical weathering in a temperate forest with experimental CO2 enrichment
TL;DR: In this paper, the authors examined how forest growth at elevated (+200 ppmv) atmospheric CO2 concentration affects CO2 dynamics in the soil and found that increased soil CO2 under FACE accelerated the rates of soil acidification and mineral weathering.
Journal ArticleDOI
Separation of root respiration from total soil respiration using carbon-13 labeling during Free-Air Carbon dioxide Enrichment (FACE)
TL;DR: In this article, the root and rhizosphere contribution to soil respiration was analyzed using a stable carbon isotope tracer, and it was found that the root contribution was correlated with the distribution of fine roots in the soil.
