“…The effects of soil moisture on biological, physical and chemical processes mediating NO emissions have been proposed in previous studies (Bollmann and Conrad, 1998;Davidson, 1993;Davidson and Schimel, 1995). Similar results of NO flux and soil temperature relations have also been observed in other studies (Hutchinson and Brams, 1992;Maljanen et al, 2007;Meixner et al, 1997;Yang and Meixner, 1997;Yu et al, 2008). This is because the dominance of soil microbial processes in the production of NO anticipates a marked influence of soil temperature on NO emission rates.…”

“…A variable number of individual chambers (e.g. to assess the spatial heterogeneity of a site, as done manually by Williams and Davidson, 1993;Maljanen et al, 2007), flexible controlling, variable operating parameters, variable number and type of analysers provide a high flexibility of the system and allow its application for numerous scientific investigations. During field experiments the system proved to be very robust and easy to maintain.…”

An automated dynamic chamber system for surface exchange measurement of non-reactive and reactive trace gases of grassland ecosystems

Abstract. We present an automated dynamic chamber system which is optimised for continuous unattended flux measurements of multiple non-reactive and reactive trace gases on grassland ecosystems. Main design features of our system are (a) highly transparent chamber walls consisting of chemically inert material, (b) individual purging flow units for each chamber, and (c) a movable lid for automated opening and closing of the chamber. The purging flow rate was chosen high enough to keep the mean residence time of the chamber air below one minute. This guarantees a proven efficient mixing of the chamber volume and a fast equilibration after lid closing. The dynamic chamber system is able to measure emission as well as deposition fluxes of trace gases. For the latter case, the modification of the turbulent transport by the chamber (compared to undisturbed ambient conditions) is quantitatively described by a bulk resistance concept.Beside a detailed description of the design and functioning of the system, results of field applications at two grassland sites are presented. In the first experiment, fluxes of five trace gases (CO 2 , H 2 O, NO, NO 2 , O 3 ) were measured simultaneously on small grassland plots.It showed that the dynamic chamber system is able to detect the characteristic diurnal cycles with a sufficient temporal resolution. The results also demonstrated the importance of considering the chemical source/sink in the chamber due to gas phase reactions for the reactive compounds of the NO-NO 2 -O 3 triad. In a second field experiment, Correspondence to: L. Pape (llehmann@mpch-mainz.mpg.de) chamber flux measurements of CO 2 and methanol were compared to simultaneous independent eddy covariance flux measurements on the field scale. The fluxes obtained with the two methods showed a very good agreement indicating a minimal disturbance of the chambers on the physiological activity of the enclosed vegetation.

“…Although NO is generated by denitrification process, nitrification is the most important source of NO, especially under aerobic conditions (Maljanen et al, 2007;Medinets et al, 2015). Regarding N 2 O emissions, nitrification and/or denitrification are (depending on the WFPS) the main processes leading to N 2 O losses, even though nitrifier denitrification can be also a relevant source of this gas, especially under certain soil conditions (Bateman & Baggs, 2005;Kool et al, 2011).…”

The application of organic and mineral fertilisers to soil can result in increased gaseous emissions to the atmosphere such as nitric oxide (NO) and nitrous oxide (N 2 O) gases. The aim of this study was to evaluate under laboratory conditions the effects on mineral N dynamics and NO and N 2 O emissions of application to soil of cattle slurry derived liquid fraction (LF) obtained by screw press and mineral fertiliser (MF), both treated with or without the nitrification inhibitor 3,4-dimethylpyrazole phosphate (DMPP). An aerobic laboratory incubation was performed over 93 days with a Dystric Cambisol amended with mechanically separated LF or mineral fertiliser ammonium sulphate only or combined with DMPP. Two additional treatments were included: soil only and soil amended with DMPP. Nitrogen immobilisation was the dominant process with MF amendment, whereas N mineralisation has been observed with LF. The application of LF reduced significantly NO emissions by 80% relative to mineral but no differences were observed with N 2 O emissions. The addition of DMPP to MF induced a decrease of 18 and 29% in NO and N 2 O emissions whereas DMPP combined with LF reduced (numerically but not statistically) these emissions in 20 and 10%, respectively. Results obtained in our study suggest that N (NO + N 2 O) losses can be mitigated by adding DMPP to mineral fertilisers or replacing mineral fertiliser by LF.Additional key words: carbon dioxide; DMPP; N emissions; N mineralisation; solid-liquid separation.
