New Insights into the Use of Rhizobia to Mitigate Soil N2O Emissions

Agriculture is a major anthropogenic source of the greenhouse gas N2O, which also involved in stratospheric ozone depletion. While use rhizobial inoculants has already been reported as an emerging option for mitigating soil N2O emissions, this study presents situ abatement 70% emission using strain nosZ+ G49 vs. nosZ− USDA138 association with soybean. Therefore, we consider that choice inoculant leguminous crop should take into account capacity strains to reduce nitrous oxide addition their N fixation capacity. This clearly suggests mitigation could be considered not only soybean but different crops, emphasis currently placed on lupin because potential its LL200 strain. The clear demonstration reduction clover symbiotic opportunities might occur grassland.
