Abstract

Carbon (C) and nitrogen (N) cycles are tightly linked since N is an important limiting resource for plant growth. Increased industrial activity, transport, and fertilization have and will increase N availability. However, the fate of N is not always clear, and neither how this affects C uptake in different ecosystem
types and climate zones. Enhanced nitrogen availability can lead to increased growth, but above a certain level the system can become N-saturated, with decreased growth response and increased
leaching of nitrogen to the groundwater. To study N induced growth versus N delivery to the groundwater, we ran the global vegetation model LPJ
-GUESS. Next, we analyzed site observations of carbon and nitrogen indices from different global datasets to study how well the model predicts the N
induced changes.
