This paper shows that the benefits for net carbon uptake by the biosphere arising from nitrogen fertilisation are offset by the emissions of nitrous oxide that result (Zaehle S, Ciais P, Friend A D and Prieur V (2011). Carbon benefits of anthropogenic reactive nitrogen offset by nitrous oxide emissions, Nature Geoscience)., doi:10.1038/ngeo1207).
