| Abstract | Gross nitrification is an important turnover rate in the soil nitrogen cycle and one of the main sources of nitrous oxide (N2O) from soils. We measured gross nitrification and N2O-emissions in soil cores from three different treated fields (mineral (N) fertilizer, farmyard manure and control) with Barometric Process Separation (BaPS) weekly over a period of one year (2004). Black earth soil samples (5-10 cm depth) were collected at Bad Lauchstädt, Germany. Gross nitrification shows a strong seasonal dynamics at the tree field sites and 58 to 79% of the observed variation could be explained with soil moisture and soil temperature. N2O-emissions ranged from 0 to 0.3725 µg N h-1 kg-1 dried soil showing a high temporal variability. Mean emission rates are 0.062, 0.028 and 0.005 µg N h-1 kg-1 dried soil for manure fertilizer, mineral fertilizer and control, respectively. The N2O-emissions can not be explained by the assumption of a "hole in the pipe" as postulated by Firestone and Davidson (1989), neither when soil temperature nor soil moisture were taken into account. |
