Figure conceptuelle Azodyn

Les modèles AZODYN (il existe un AZODYN-blé, AZODYN-colza, AZODYN-pois, AZODYN-intercrop (pour une association blé-pois), et nous sommes en train de fabriquer un AZODYN-orge) visent à simuler le fonctionnement d’une culture (de blé, pois, colza, association blé-pois), y compris en cas de stress biotiques, en vue d’être utilisés comme outil de raisonnement de techniques culturales (notamment fertilisation azotée, choix variétal et dates de semis) ou de prédiction de la production (quantitative et qualitative), en fonction des techniques culturales appliquées et du climat. Ils sont conçus sur le principe de production de biomasse (Monteith) et élaboration du rendement (via l’élaboration des deux composantes, nombre de grains/m2 et poids moyen d’un grain) et de la qualité des grains. Ils incluent des variables de sortie caractérisant des impacts environnementaux de la production. Leurs variables d’entrée sont d’accès aisé en parcelles agricoles.

Mots clés : modèle dynamique, azote, rayonnement, température, eau, variété
