The French Law for the Recovery of Biodiversity, Nature and Landscapes has set a target of reducing the net loss of biodiversity to zero. This biodiversity action plan aims to put this goal into action. One of his aims is to improve our knowledge of soil biodiversity and to develop agricultural and forestry practices that allow it to be conserved restored and developed. This plan can build on several initiatives that were launched since the early 2000's between the French soil science sphere and the French state to improve knowledge on soil biodiversity and to develop indicators relevant for soil quality monitoring and land use decision The implementation in soil monitoring and participatory observatory networks allowed to gain experience on numerous soil types, land uses and agricultural practices and to establish the first reference values e.g. for microbiological characteristics at national scale. The standardisation of protocols, the industrialisation of soil biological analyses, the emergence of advisory services offer based on soil bioindicators allow these tools to be mobilised by the greatest number of soil managers.
