Monitoring soil microbial activity

Promoted by Stéphane Bazot from UMR 8079, Laboratory Ecology, Systematics and Evolution of Paris-sud University, a team led by Gaëlle Vincent came to OPTMix in March and mid-June for two campaigns to monitor soil microbial activity. Soil samples were taken for structural analyzes of the communities of bacteria, archaea and fungi. To complete, soil respiration measurements were coupled for the campaign in June to characterize this part of the carbon cycle as a function of stand density.

At the same time, the Irstea team associated with Sébastien Gogo, from ISTO Orléans, measured soil respiration with large chamber in mixed stands like last year. In addition to the inter-annual variation, the measurements will allow inter-device comparison.
