Biodiversité microbienne des sols : du territoire national aux agriculteurs My speech will focus on the development of a biogeographical approach to study the spatial distribution of soil microbial community in terms of abundance and diversity on the scale of France. We have reached this goal by the application of molecular tools based on soil DNA extraction and characterization on the 2200 soils of the French national monitoring network. This approach enabled us to draw the biogeographical patterns of molecular microbial biomass as well as bacterial community richness and evenness on the scale of France. By this way we have identified and rank the several ecological processes involved in community assembly as well as the different environmental drivers. In addition, we have also revisited the concept of taxa area relationship for microorganisms at this scale. The set of microbial data obtained from the RQMS survey enabled us to build up the first reference system of soil microbiology on a broad scale. My speech will end with the demonstration that these molecular microbial tools can be operational to diagnose soil quality in an agricultural network of 250 farms distributed across France.
Lionel RANJARD is a research scientist from INRA department “Environment and Agronomy” in the UMR “Agroécologie” INRA Dijon. He takes its position in November 2001 after a PhD in microbial ecology at university Claude Bernard (Lyon1, France) and a post-doctoral position in bacterial genetic.
He is the coordinator of numerous scientific programs dealing with microbial biogeography at different spatial scales (from plots to French territory ECOMIC-RMQS project). More recently he has managed scientific programs with the goal to develop an operational set of bio indicators to diagnose agricultural soil quality and evaluate the impact of farming practices (AgrInnov project).
