Influence of microbial diversity on soil organic carbon dynamics highlighted by a 13C-labelling technique
2012
Soil organic matter (SOM) represents the main pool of carbon within the biosphere, estimated at roughly twice that in atmospheric CO2. In agrosystems, organic amendments are common to maintain soil C stocks. However, recent studies have revealed that these practices can lead to a priming effect, corresponding to enhanced release of CO2 into the atmosphere, due to over-mineralisation of soil organic carbon. Therefore, appropriate decisions regarding organic input management require better understanding of the biogeochemical cycles related to SOM dynamics. As soil microorganisms are major actors in SOM turnover, their diversity is likely to influence SOM dynamics. In this context, the relatio…
Soil carbon, multiple benefits
2014
Made available in DSpace on 2018-12-11T17:24:47Z (GMT). No. of bitstreams: 0 Previous issue date: 2015-01-01 In March 2013, 40 leading experts from across the world gathered at a workshop, hosted by the European Commission, Directorate General Joint Research Centre, Italy, to discuss the multiple benefits of soil carbon as part of a Rapid Assessment Process (RAP) project commissioned by Scientific Committee on Problems of the Environment (SCOPE). This collaboration led to the publication of the SCOPE Series Volume 71 Soil Carbon: Science, Management and Policy for Multiple Benefits; which brings together the essential scientific evidence and policy opportunities regarding the global importa…
