External organic matters for climate mitigation and soil health

EOM4SOIL aims at proposing best management practices of external organic matter (EOM) pre-processing and application on soil to contribute to climate change mitigation and improve soil health. Representative farming systems in Europe (arable crops and vineyards) are selected, taking into account the diversity of pedoclimatic conditions. The net budget of soil C storage and greenhouse gas emission including the pre-process step and field application, is assessed as well as the multiple effects of EOM application on soils including contaminants are quantified. Innovative pre-processing are recommended to improve C budget and soil health. The best management practices are defined from scenarios of use assessed with a multicriteria simulation tool, parameterized from long-term experiments.
