A soil biodiversity survey coupled with the national soil quality monitoring network?

International audience; Despite its importance for human activities, soil biodiversity remains largely unknown and threatened. Aware of the need for large-scale monitoring, we studied the feasibility to add a soil biodiversity survey (RMBS-Biodiversity) to the already existing French soil quality monitoring network (RMQS). We worked with soil biodiversity experts to couple RMBS-Biodiversity with RMQS i.e. to choose soil taxons and functions, the methodologies and the sampling design. According to the experts, the sampling design of RMQS fits with a soil biodiversitysurvey. We propose sampling protocols for i) bacteria and fungi, ii) protists, iii) nematodes, iv) mesofauna (particularly spri…

Global data on earthworm abundance, biomass, diversity and corresponding environmental properties

Earthworms are an important soil taxon as ecosystem engineers, providing a variety of crucial ecosystem functions and services. Little is known about their diversity and distribution at large spatial scales, despite the availability of considerable amounts of local-scale data. Earthworm diversity data, obtained from the primary literature or provided directly by authors, were collated with information on site locations, including coordinates, habitat cover, and soil properties. Datasets were required, at a minimum, to include abundance or biomass of earthworms at a site. Where possible, site-level species lists were included, as well as the abundance and biomass of individual species and ec…

How to add a biodiversity survey to an already existing national pedologic survey? Case study of the french soil quality monitoring network

International audience; Despite its importance for human activities, soil biodiversity remains largely unknown. This gap of knowledge is a strong limit for studies including it such as in the agricultural field. Particularly, in France, no large-scale monitoring of soil biodiversity exist for the moment except for microorganisms (bacteria and fungi). Aware to this need, with the support of OFB, we studied the feasibility to add a soil biodiversity survey (RMQS-Biodiversity) to the already existing French soil quality monitoring network (RMQS). It is a systemic monitoring based on a 16*16 km grid where the sampling is done on a plot at the center of the mesh, which could belong to different …

Effets de l’apport de composts sur la biodiversité des sols

National audience; Les sols remplissent des services écosystémiques indispensables à la vie humaine parmi lesquels celui d’approvisionnement en aliments et de régulation, par le stockage, la transformation et le transfert, de l’eau et des éléments tels que le carbone, l’azote, etc.. La matière organique est un élément déterminant du maintien de ces services de par son incidence sur la structure physique des sols, leurs caractéristiques chimiques et leur activité biologique. De fait, si le retour au sol de la matière organique issue du compostage des déchets et des produits résiduaires organiques est une pratique ancestrale, son intérêt ressurgit aujourd’hui face aux défis démographiques, al…
