The French Soil Quality Monitoring Network assesses the evolution of French soil properties, thanks to a monitoring of more than 2000 sites every 15 years, supplemented by a survey of land management practices on the sampled plots. These survey data need to be completed in order to better understand the effect of land management practices on soil properties. The ALAMOD project aims to complete the survey data in order to assess the impacts of management practices on soil quality. The datasets produced during the project will then be shared with national research communities in order to estimate carbon stock evolution in soil and biomass.
