Improving environmental performances of organic spreading technologies through the use of life cycle assessment
Résumé
Life Cycle Assessment (LCA) is generally used to assess environmental performances of a product or a system. Some agricultural LCA were carried out to assess environmental performances of fertilisation processes, but they barely take into account the direct contributions of agricultural machinery. In this paper, we develop the three step method used to assess the environmental impacts of organic spreading using the LCA approach in order to ecodesign organic spreaders (building technological indicators, establishing a link between these indicators and nitrogenous emissions, and assessing fuel consumption of tractors during all the spreading processes). We achieve a LCA study for 45 spreading scenarios and compare environmental performances of spreading machines according to the main LCA environmental impacts. LCA results mainly show that pedoclimatic conditions have an influence on the environmental impacts of spreading scenarios especially for acidification, eutrophication, and global warming and that environmental impacts present significant differences between spreading machines.
