“…The increasing anthropogenic N deposition affects N balance in terrestrial ecosystems (Kugler et al, 2008;Jiang et al, 2010;Li et al, 2012), and accordingly, the production and emission of N 2 O were inevitably influenced by the variations in the availability of ammonium and nitrate in the soil (Weier et al, 1993;Rafique et al, 2011).…”

A B S T R A C TThe Chinese steppe is undergoing a drastic increase in nitrogen (N) deposition, and the precipitation in this region is predicted to increase. However, the response of soil N 2 O emissions to the coupling changes of precipitation and N deposition in grassland ecosystem has been seldom discussed. A manipulative field experiment was conducted to investigate the individual and interactive effects of precipitation increase and N deposition on soil

“…The exchange of NH 3 between the land surface and the atmosphere has long been a key uncertainty in quantifying atmospheric budgets and nitrogen deposition (e.g., Eriksson, 1968;Söderlund and Svensson, 1976;Fowler et al, 1989;Langford et al, 1992;Sutton et al, 1993cSutton et al, , 1994Hertel et al, 2006;Kugler et al, 2008). Biosphere-atmosphere exchange of NH 3 is complicated by the existence of bi-directional fluxes for a wide range of land surfaces: the net flux at any time represents the combination of several opposing component fluxes, with leaf surfaces, leaf intercellular matrix, leaf litter and the soil surface (e.g., Denmead et al, 1978;Sutton et al, 1995aSutton et al, , b, 2000bSutton et al, , 2001aHarper et al, 1996;Wyers and Erisman, 1998;Nemitz et al, 2000aNemitz et al, , 2004aMassad et al, 2008).…”

Abstract.A major international experiment on ammonia (NH 3 ) biosphere-atmosphere exchange was conducted over intensively managed grassland at Braunschweig, Germany. The experimental strategy was developed to allow an integrated analysis of different features of NH 3 exchange including: a) quantification of nearby emissions and advection ef- The prior analysis established the spatial and temporal design of the experiment, allowing significant synergy between these objectives. The measurements were made at 7 measurement locations, thereby quantifying horizontal and vertical profiles, and covered three phases: a) tall grass canopy prior to cutting (7 days), b) short grass after cutting (7 days) and c) re-growing sward following fertilization with ammonium nitrate (10 days). The sequential management treatments allowed comparison of sources-sinks, advection and aerosol interactions under a wide range of NH 3 fluxes.Published by Copernicus Publications on behalf of the European Geosciences Union. This paper describes the experimental strategy and reports the grassland management history, soils, environmental conditions and air chemistry during the experiment, finally summarizing how the results are coordinated in the accompanying series of papers.

“…Measured and calculated wet and dry fluxes of different N forms can be seen in Table 4. The wet N depositions as nitrate and ammonium were lower (3.6 kg N ha −1 ) than was measured earlier at a grassland site with similar characteristics (K‐Puszta, 20 km from Bugac; 4.7 kg N ha −1 during regular years; Kugler et al , 2008). Precipitation amounts for August to December 2006 and January to July 2007 were 133 and 221 mm, respectively, amounting to a sum of 354 mm year −1 for the 12‐month measurement period, against the average yearly precipitation of 553 mm year −1 .…”

In Hungary, the N balances for forests (Horváth et al , 2006) and for lake and grassland (Kugler et al , 2008) were established on the basis of field measurements. In the work of Kugler et al (2008), the soil flux of nitrous oxide was estimated for semi‐arid grassland, while the soil‐atmosphere exchange of N 2 , NH 3 and NO was neglected, given the lack of measurements.…”

The aim of this work is to estimate the net N balance (deposition – emission) between the atmosphere and a semi‐arid, semi‐natural grassland (Bugac station, Central Hungary, CarboEurope IP, NitroEurope IP level 3 site). Dry deposition of N compounds has been determined by the inferential method, based on continuous monitoring of NO2 gas and daily 24‐hour concentration measurements of HNO3 vapour, NH3 gas, and NH4+ and NO3− particles, using dry deposition velocities from the literature, measured above surfaces with the same characteristics as Bugac station. The bi‐directional flux of NH3 within the atmosphere and the canopy (excluding soil emission) has also been estimated by the inferential method. Wet deposition of nitrate and ammonium ions was calculated on the basis of daily precipitation sampling and concentration measurements of nitrate and ammonium ions. To estimate the soil‐atmosphere exchange of different gaseous N forms (N2, NO, N2O, NH3), the DNDC model was used as validated by the chamber measurements of NO and N2O soil emission fluxes. Soil emissions of NO and N2O have been determined by dynamic and static soil chamber methods, respectively. The measurement and modelling activity covers a complete year. Using the measured and modelled data, the calculated N balance at Bugac station between August 2006 and July 2007 is estimated at −8.8 kg N ha−1 year−1 (deposition) as a sum of the deposition and emission terms (−10.4 and 1.6 kg N ha−1 year−1, respectively). Due to the warm and dry weather during the examined period, wet fluxes were substantially lower than usual, which may also have altered the regular yearly course of dry deposition and emission.
