| At the experimental station Viehhausen, 30 km north of Munich in southern Germany, N2O, CO2 and CH4 fluxes between soil and atmosphere were measured to investigate the influence of site-related factors and cultivation-technique on the emissions of these greenhouse gases. Clover-grass as well as several wheat cropping systems (with and without biogas slurry) were analyzed under the conditions of organic farming. This paper shows the results of the vegetation period of 2009. The N2O emissions from the wheat fields were higher than those from clover-grass fields. Ploughing-in of the legume-grass biomass resulted in releasing distinctive N2O emissions. For CH4 fluxes the arable soils were a net sink, especially in cropping systems with winter wheat. |
