An overview of Nitrogen fertilization practices in France.
Résumé
INTRODUCTION
Nitrogen (N) fertilisation is a key element to ensure crop yield and thus food security. Amongst numerous other factors, the amount of N applied in fields is driven by the type of culture and soil, as well as by economics and temporal factors. However, this fertilisation is also a source of multiple environmental impacts (soil acidification, water eutrophication, global warming and air quality depletion). In order to
mitigate the impacts, politics are developed at large scale, usually national, whereas the impacts happen at a finer scale. Besides, the range of products available for famers is always wider. Detailed information on the N fertilisation is thus crucial to develop mathematical models to evaluate yields and/or environmental impacts. This study is aiming at presenting on overview of the organic and mineral N fertilisation in France for the crop years 2005-06 and 2010-11. A focus is carried on the latter as the available information is more precise
