Soil organic carbon (SOC) is a key soil component. SOC stores large amounts of carbon and it also affects water fl uxes as well as the availability of nutrients. Soil water fl uxes are impacted by SOC directly due to its effect upon soil hydraulic parameters. Also many indirect effects ...

BEIJING, Nov. 23 (Xinhua) -- A group of Chinese researchers issued a data map of the soil organic carbon (SOC) content for global black soil regions, shedding light on the quantification of agro-ecosystems and global food security, according to the recent issue of the journal Remote Sensing...
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
We found that the compression index was independent of SOC, but the void ratio at any given effective stress was highly correlated with organic carbon content. By comparison with uniaxial compression data, the apparent influence of SOC on the compression index is likely to be due to its effect...
1) Soil organic carbon 土壤总有机碳1. The organic carbon accumulation capability of two typical tidal wetlands in Dongtan of Chongming Island was compared by analyzing on differences of soil organic carbon content and vegetation input,and the main reason of those differences was studied by ...
and soil carbon content (a-b-c). A negative (i.e. stabilizing) feedback loop links atmospheric CO2, vegetation productivity, and root–microbe associations (d-e-f), which affect and are influenced by soil carbon content (j).Dashed arrowsrepresent uncertain feedbacks involving changes in water...
