Contribution de l’agriculture à l’effet de serre
Oléagineux, Corps gras, Lipides, 2008 Agriculture contributes to almost 20% of greenhouse gas emissions in France, and the same applies for most EU countries. This is due to a large extent to N2O emission after N fertilizer application, but the emissions are very variable in space and time ...
