Relevance of different soil fauna and microflora groups in the monitoring of soil biodiversity: RMQS-Biodiv, a french Pilote area experience

affiche, résumé; Soil biota play essential roles in delivering key ecosystem goods and services, and are both directly and indirectly responsible for acting in many important functions (nutrient release, soil structure maintain, contribution to water storage). It is thus essential to characterize both the species diversity and the biological functions. In order to monitor soil biodiversity (species and function) in relation to land use (mainly agricultural practices) and pedoclimatic parameters, a French program « RMQS-biodiv » was developed at a wide regional scale (Brittany). An important national research collaboration (12 research teams) supported the program, that undertook the study o…

Impact de pratiques culturales sur les caractéristiques du sol

National audience; Plusieurs caractéristiques d'un sol ont été évaluées dans une parcelle expérimentale du Ctifl, suite à l'apport d'amendements organiques ou une biodésinfection (culture de radis fourrager, broyage et enfouissement, roulage, bâchage avec film plastique puis semis de carottes). Les résultats de la première année montrent que la biodésinfection a un impact marqué sur les communautés de microbes et de nématodes des sols, et que cette pratique réduit significativement la sensibilité des sols à la fonte de semis due à R. solani.

Soil health through soil disease suppression: Which strategy from descriptors to indicators?

International audience; Soil is a component of primary importance in crop production, even if it is often neglected, or only regarded as a physical support for the growth of plants. However, with the increasing societal concerns for the sustainability of agriculture, soil must be considered as a living system. Its quality results from the multiple interactions among physicochemical and biological components, notably the microbial communities, primordial for soil function. Crops are threatened by soil-borne diseases. These are often difficult to control, because of the “hidden” status of the pathogens and also because of the absence, noxiousness or lack of efficacy of chemical treatments. In…
