Description: Das Projekt "Nitrosolair" wird vom Umweltbundesamt gefördert und von Ecole Polytechnique Federale de Lausanne (EPF), Institut d'Amenagement des Terres et des Eaux (IATE) durchgeführt. A N-balance is made by means of the 15 N technique and direct measurement of gaseous NO and NO losses. These experiments are carried out at a pilot plot at the agricultural research station Changins (Switzerland) which is sown with a rotation of six crops. Unconfined microplots, fertilized with N-annonium-nitrate are created at the plot. The course of labelled N is followed in the plants and the soil. The difference between in- and output - often attributed to gaseous N losses - is mainly due to nitrification and denitrification. To quantify these losses, NO and NO fluxes are measured directly by means of the cover method. (FRA)
