Utilisation des symbiotes des légumineuses pour réduire les émissions de N2O

Symbiotes légumineuses et N2O : Les rhizobia symbiotes de certaines légumineuses sont capables de réduire le gaz à effet de serre N2O en N2
Utilisation des symbiotes des légumineuses pour réduire le puissant gaz à effet de serre, N2O

Les sols, et ainsi les activités agricoles, sont la principale source de N2O, puissant gaz à effet de serre. Les émissions de N2O par les sols sont la résultante du fonctionnement de mécanismes microbiens conduisant à la production de ce gaz (nitrification et premières étapes de la chaîne de dénitrification) et du mécanisme microbien de consommation de ce gaz (dernière étape de la chaîne de dénitrification). Une possibilité pour réduire les émissions de N2O par les sols est d’y amplifier la fonction de réduction de N2O en N2, en créant des puits de N2O. Au cours d’expérimentations en serre sur du sol cultivé avec du soja inoculé par différents micro-organismes naturels symbiotiques du soja, nous avons transformé un système émetteur de N2O en un système consommateur de ce gaz. Des travaux complémentaires de modélisation ont montré l'intérêt environnemental qu’il y aurait à développer des cultures de légumineuses inoculées avec des Rhizobia d'intérêt, puits de N2O.
