Water level such as moistened condition hastened the CO2-C evolution during decomposition of organic residues. Carbon dioxide emission results were statistically significant at all the studied durations except at 7th and 49th day. Higher carbon dioxide emission was observed in moistened condition than i...
For instance, >80% of global carbon dioxide (CO2) emissions come from natural energy and resource consumption, which contributes >85% of all particulate matter (PMx) and nearly all sulphur dioxide (SO2) and nitrogen oxide (NOx) emissions (IEA, 2022; IPCC, 2014). Unlike the representativeness...
Methyl bromide is an excellent fumigant but has been banned because it has high potential for depleting the ozone layer which leads to many environmental and human health hazard issues. In this connection, effectiveness of carbon dioxide (CO2, 99.9%) was studied as an alternative to methyl bromid...
However, trees can lower levels of the so-called “greenhouse gas(mainly carbon dioxide)” and evaporate (使……蒸发) water into the atmosphere(大气)to increase cloudiness. Clouds can reflect solar radiation (太阳辐射) so therewill be 1 5heat on earth.Trees absorb rainfall and allow the ...
The carbon cycle includes important fluxes of methane (CH4) and carbon dioxide (CO2) between the ecosystem and the atmosphere. The fluxes may acquire either positive (release) or negative values (consumption). We calculated these fluxes based on short-campaign in situ chamber measurements from four...

Furthermore, in the studied soils, the highest amount of cumulative mineralized carbon was measured at natural soil salinity levels (i.e., low salinity 0.84–1.1 dS/m) and the lowest amount of cumulative mineralized carbon was measured in high salinity treatments. In all three soils, the ...
The Permian–Triassic mass extinction is characterized by a massive injection of carbon dioxide associated with Siberian Traps volcanism, pronounced global warming and ocean acidification. However, in the absence of high-resolution records of atmospheric CO2 (pCO2), detailed changes in the carbon cycle...
