At present, the management of the organic status of agricultural soils and their fertility is based on "routine" soil analysis associated with the humic balance. The information collected allows farmers to manage mainly the mineral fertilization of their soil. While farmers have many expectations to improve the management and services provided by soils, the evaluation of the microbiological state of soils in relation to the organic status is still at an embryonic stage.

With this in mind, the CASDAR Microbioterre project aims to integrate microbiological analyses into routine soil analyses performed by laboratories in order to improve the management and services provided by agricultural soils.

This project is led by ARVALIS, in partnership with the Institut Polytechnique UniLaSalle, AUREA AgroSciences, the Chambre d'Agriculture de Bretagne, INRAE, ITAB and Terres Inovia.

The results of this work have made it possible to identify the most robust indicators, to reference them and to better understand the impact of agricultural practices on biological activity. In the long term, the use of soil microbiology indicators in addition to routine soil analysis will improve diagnosis and advice for the management of cultivation practices that restore carbon to the soil and have a positive impact on soil biological activity.
