Soil respiration is the primary path by which CO2fixed by land plants returns to the atmosphere. Estimated at approximately 75 × 1015gC/yr, this large natural flux is likely to increase due changes in the Earth's condition. The objective of this paper is to provide a brief scientific review for policymakers who are concerned that changes in soil respiration may contribute to the rise in CO2in Earth's atmosphere. Rising concentrations of CO2in the atmosphere will increase the flux of CO2from… 
Soil CO2 dynamics, acidification, and chemical weathering in a temperate forest with experimental CO2 enrichment
Soils constitute a major component of the global carbon cycle that will be affected by anthropogenic additions of CO2 to the atmosphere. As part of the Duke Forest Free‐Air CO2 Enrichment (FACE)
The temperature response of soil microbial efficiency and its feedback to climate
Soils are the largest repository of organic carbon in the terrestrial biosphere. Nevertheless, relatively little is known about the factors controlling the efficiency with which microbial communities
Advances in the Temperature Sensitivity of Soil Respiration and Carbon Balance
Global warming has led to a positive feedback loop between global carbon cycle and climate system, which will help answer regional climate change and global carbon balance. The sensitivity of soil
Soil Organic Carbon Stocks and Soil Respiration in Tropical Secondary Forests in Southern Mexico
The soil CO2 efflux is recognized as one of the largest fluxes in the global carbon cycle, and small changes in the magnitude of soil respiration could have a large consequence on the concentration
Soil Carbon Stock and CO2 Flux in Different Ecosystems of North-East India
Soil carbon stock and soil CO2 flux are the major components of carbon budget and carbon cycle in the different terrestrial ecosystems of the world. Soils are the largest carbon reservoirs of the
Prospects of Soil Organic Carbon Sequestration: Implications for Nepal's Mountain Agriculture
Agricultural land is one of the major sources of carbon dioxide (CO 2 ) emission, which results in an increase of the CO 2 concentration in the atmosphere. The conversion of biomass rich land like

Warming increases soil respiration in a carbon-rich soil without changing microbial respiratory potential
Abstract. Increases in global temperatures due to climate change threaten to tip the balance between carbon (C) fluxes, liberating large amounts of C from soils. Evidence of warming-induced increases

Roots exert a strong influence on the temperature sensitivityof soil respiration
The temperature sensitivity of soil respiration will largely determine the effects of a warmer world on net carbon flux from soils to the atmosphere. CO2 flux from soils to the atmosphere is
Evidence from chronosequence studies for a low carbon-storage potential of soils
OVER most of the Earth's land surface, the amount of carbon stored in soil organic matter exceeds by a factor of two or three the amount stored in living vegetation. This pool of soil carbon is large
Carbon Fluxes in Plant-Soil Systems at Elevated Atmospheric CO2 Levels.
TLDR
In this paper the major controls of carbon translocation via roots into the soil as well as the subsequent microbial turnover of root-derived carbon are reviewed and possible consequences of an increased CO2 level in the atmosphere on these processes are discussed.
The global carbon dioxide flux in soil respiration and its relationship to vegetation and climate
We review measured rates of soil respiration from terrestrial and wetland ecosystems to define the annual global CO 2 flux from soils, to identify uncertainties in the global flux estimate, and to

The concentration of carbon dioxide (CO2) in the Earth's atmosphere is rising rapidly, with the potential to alter many ecosystem processes. Elevated CO2 often stimulates photosynthesis, creating the
Comparison of carbon dynamics in tropical and temperate soils using radiocarbon measurements
The magnitude and timing of the response of the soil carbon reservoir to changes in land use or climate is a large source of uncertainty in global carbon cycle models. One method of assessing soil
