Short summary
The article describes the implementation of the nitrogen cycle in the land surface model ISBA (Interaction-Soil-Biosphere-Atmosphere). The model is evaluated using Free Air CO2 Enrichment experiments. A comparison with a multi-model analysis shows that the nitrogen model version performs better than the carbon-only version, notably a reduced sensitivity to elevated CO2, and smaller C stocks. We also present a detailed analysis of the simulated N dynamics in the soil.
