Soils store two or three times more carbon than exists in the atmosphere as CO2, and it is thought that the temperature sensitivity of decomposing organic matter in soil partly determines how much carbon will be transferred to the atmosphere as a result of global warming1. Giardina and Ryan2 ...
and it is thought that the temperature sensitivity of decomposing organic matter in soil partly determines how much carbon will be transferred to the atmosphere as a result of global warming1. Giardina and Ryan2have questioned whether turnover times of soil carbon depend on temperature, however, o...

Alpine grassland soils on Qinghai-Tibet Plateau store approximately 33.5 Pg of organic carbon (C) at 0–0.75 m depth and play an important role in the
Soils contain a stock of carbon that is about twice as large as that in the atmosphere and about three times that in vegetation. Small losses from this large pool could have significant impacts on future atmospheric carbon dioxide concentrations, so the response of soils to global warming is of...
摘要: Aims Climate warming has been hypothesized to influence dynamics of soil organic carbon (SOC), especially labile SOC due to its rapid response to changes in temperature and carbon (C) supply. In this...关键词: Soil organic carbon (SOC Experimental warming Labile organic carbon C3–C4 ...
(e.g.,;Salzer et al., 2009;Körner, 2012;Silva et al., 2016). Other examples include temperate regions across western North America, where the net effect of warming and elevated CO2has resulted in enhanced tree growth andevapotranspiration, outpacing decreases instomatal conductancefrom elevated...
摘要: Increasing the soil organic carbon (SOC) content in croplands can not only improve the soil fertility, but also mitigate climate warming. To evaluate the extent of soil organic carbon density (SOCD) a关键词:Carbon density DNDC model Topsoil Croplands China Soil organic carbon ...
