Predicting in situ soil N2O emission using NOE algorithm and soil database

2005

This paper presents a new algorithm, Nitrous Oxide Emission (NOE) for simulating the emission of the greenhouse gas N2O from agricultural soils. N2O fluxes are calculated as the result of production through denitrification and nitrification and reduction through the last step of denitrification. Actual denitrification and nitrification rates are calculated from biological parameters and soil water-filled pore space, temperature and mineral nitrogen contents. New suggestions in NOE consisted in introducing (1) biological site-specific parameters of soil N2O reduction and (2) reduction of the N2O produced through nitrification to N2 through denitrification. This paper includes a database of 6…

Contribution de l'agriculture à l'effet de serre. Importance de l'azote et interactions avec l'ozone

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, due mainly to the variability in environmental conditions. However, the figure of the relationship between agriculture and greenhouse effect is more complex. First a significant fraction of emitted N2O does not occur where N has been applied, but is due to indirect emissions in wetlands or forest where N is transferred by natural pathways. This implies the need to make an assessment at larger scale than the field where N is applied. Many oth…

Principes de fonctionnement de la symbiose fixatrice de l’azote : impacts agronomiques et environnementaux.

2017

National audience; Par leur capacité à s’associer avec des bactéries du sol fixant l’azote atmosphérique, les légumineuses ont la particularité de pouvoir être cultivées sans utiliser d’engrais azotés, et d’être une source d’azote pour d’autres cultures. Elles ont ainsi un rôle particulier dans la gestion des flux d’azote au sein des systèmes de culture, et dans les bilans environnementaux qui en découlent. Dans ce texte, nous décrivons le processus de fixation symbiotique de N2 au cours de la culture, en considérant sa réponse à la disponibilité en nitrate, et aux autres facteurs environnementaux et facteurs génétiques. Puis, nous explicitons la façon dont la minéralisation des résidus de …
