Carbon cycling in soil
www.frontiersinecology.org © The Ecological Society of America S contain a huge and dynamic pool of carbon (C), that is a critical regulator of the global carbon budget. As the repository for more than three-fourths of the earth’s terrestrial C, soils store 4.5 times the amount of C contained in vegetation (Lal 2004). Small changes in the processes governing soil C cycling have the potential to...
متن کاملDecadally cycling soil carbon is more sensitive to warming than faster-cycling soil carbon.
The response of soil organic carbon (SOC) pools to globally rising surface temperature crucially determines the feedback between climate change and the global carbon cycle. However, there is a lack of studies investigating the temperature sensitivity of decomposition for decadally cycling SOC which is the main component of total soil carbon stock and the most relevant to global change. We tackl...
متن کاملPlant diversity increases soil microbial activity and soil carbon storage.
Plant diversity strongly influences ecosystem functions and services, such as soil carbon storage. However, the mechanisms underlying the positive plant diversity effects on soil carbon storage are poorly understood. We explored this relationship using long-term data from a grassland biodiversity experiment (The Jena Experiment) and radiocarbon ((14)C) modelling. Here we show that higher plant ...
متن کاملMicrobial control over carbon cycling in soil
A major thrust of terrestrial microbial ecology is focused on understanding when and how the composition of the microbial community affects the functioning of biogeochemical processes at the ecosystem scale (meters-to-kilometers and days-to-years). While research has demonstrated these linkages for physiologically and phylogenetically "narrow" processes such as trace gas emissions and nitrifica...
