The ECODEFI project aims to evaluate environmental effects of organic product spreading according to several ways of application. The objective is to improve the global spreading process. The evaluation of the environmental impacts generated by organic product spreading is obtained from Life Cycle Assessment (LCA). LCA uses industrial and agronomical databases but the LCA agricultural machinery database is not well adapted to French spreading machines. The task consists in defining relevant indicators specifically for spreaders of solid and liquid organic product and in measuring performances of commercial spreaders. The indicators are spreading parameters(regularity of the distribution, working width, respect of the application rate, edge spreading), soil impact(compaction, area, and wheel pressure), performance (energy consumption, capacity, and efficiency), and human adaptability (handbook, setting, safety). The representation by radar shows each indicator before and after improvement on the machine.
