Nitrous oxide emissions are generally induced by fertiliser application. Emission strength varies with soil type, temperature and moisture and is substantially crop specific. There is a considerable difference between woody species and cereals. While the Intergovernmental Panel on Climate Change (IPCC) general N20 emission value is set to 1.25% of the nitrogen applied an average of 0.8 to 1.0% could be found from sandy soils.

Fig. 1.2), most of which escapes to the atmosphere (see Fig. 1.1 as well as Chapter 2 by Bange, this volume). Nitrous oxide acts as a greenhouse gas that is more than 200 times more potent than CO2 (Ramaswamy et ah, 2001). Therefore variations of this gas in the atmosphere can lead to changes in Earth s temperature and cHmate. Since the oceanic emission of N2O constitutes a substantial fraction to the total emission of N2O into the atmosphere, N2O provides for a direct potential link between the ocean nitrogen cycle and Earth s climate.
