“…This has been receiving considerable concern. However, NO is another important N loss species from forest soils (Butterbach-Bahl et al 2002;Hall and Matson 1999;Horváth et al 2006;Pilegaard et al 2006;Venterea et al 2003), and in some cases, the NO emission rate is even larger than N 2 O emission rate in N-deposited and N-fertilized forest sites (Butterbach-Bahl et al 2002;Pilegaard et al 2006;Venterea et al 2003). As summarized in Table 3, NO emission rates from European coniferous forests are highly correlated with N deposition, with the highest average annual emission rate up to 81.7 μg NO-N m −2 h −1 (Pilegaard et al 2006).…”

“…However, as shown in Tables 1 and 2, there is a lack of data or useful indexes (e.g., N application/deposited rates) to indicate how much N added or deposited to forest ecosystems will induce a shifted change in the amounts and rates of microbial N immobilization as well as a shifted response of other soil N processes. Background rates of atmospheric N deposition in the study site were referred to the data of Fluckiger and Braun (1998) c No background rates of atmospheric N deposition were available to calculate R The ratio of N losses as N 2 O and NO (estimated emission rates of N 2 O and NO) to N deposited and added (the rates of N deposition and fertilization application) was calculated based on the method used by Horváth et al (2006) 2.2 N mineralization…”

Purpose Understanding how process-specific nitrogen (N) transformations in natural forest soils are modified by N deposition and fertilization is critically important to gain mechanistic insights on the links between global N deposition and N enrichment and loss in forest soils. Materials and methods Here we identify the general characteristics and the main mechanisms of N deposition-and fertilization-induced modifications in multiple N transformations, including N immobilization, N mineralization, nitrification (autotrophic nitrification and heterotrophic nitrification), and denitrification, in forest soils by literature survey. Results and discussion Overall, N status, soil C/N ratios, C availability, and soil pH are key factors separately and/or interactively affecting the effects of N deposition and fertilization on forest soil N transformations. In the N-limited stage, N deposition and fertilization can act as a stimulator of N mineralization by removing microbial N limitation and reducing the C/N ratios of the substrate being decomposed. In the Nunlimited stage, N added to forest ecosystems can retard N mineralization, which may primarily be a result of decreased microbial activity due to soil acidification and low C availability. The changes in N mineralization may drive a corresponding change in N immobilization, autotrophic nitrification, and denitrification. Despite the fact that ammonia-oxidizing archaea (AOA) has a higher affinity than ammonia-oxidizers (AOB) for low-concentration ammonia (NH 3 ), low NH 3 availability may still limit the rate of ammonia oxidation (autotrophic nitrification) in acidic forest soils even in the case of high NH 4 + input. Heterotrophic nitrification, however, may be favored if soil C/N ratios and pH decrease with N deposition and fertilization. The responses of denitrification and N 2 O emission to N deposition and fertilization in forests may be nonlinear, with a trend of stimulation in the short term but a decline over time, partly because soil pH has a contrast effect on denitrification capacity and N 2 O emission. Conclusions There are various effects of N deposition and fertilization on forest soil N transformations; thus, their responses to N deposition are still not well characterized and understood. N deposition-and fertilization-induced modifications in soil N transformations have important implications for N enrichment, N loss, and soil acidification in forest ecosystems. In the future, more research is required to investigate on dissimilatory nitrate reduction to ammonium (DNRA) process and link microbial community characteristics and functions of microbial extracellular enzymes with these rate processes in forest soils to narrow the uncertainty in evaluating and predicting ecosystem responses to global N deposition.

“…In a moist tropical forest in the Amazon during a rainfall-exclusion experiment lower annual N 2 O emissions were registered in four out of five treatment years and then recovered during the first year after the drought treatment stopped (Davidson et al 2008). In contrast, in 2003 higher annual N 2 O fluxes were observed in a grassland in the South East of Ireland (Hyde et al 2006), in forests in Austria (Kitzler et al 2006) and Hungary (Horváth et al 2006;L. Horváth, personal communication).…”

To better understand the effects of increased N input and dry periods on soil nitrous oxide (N 2 O) emission, we examined a unique data-set of weather, soil microclimate, N input, and N 2 O emissions (using the eddy covariance method), measured at a fertilized grassland over the period 2003-2008. We found that the N 2 O emission (11.5 kg N ha -1 year -1 ), the ratio of N 2 O emission to N input (3.4), and the duration of elevated N 2 O flux (57 days) in 2003 were about two times greater than those of the following years. 2003 had the highest annual N input (343 kg N ha -1 year -1 ) which exceeded the agronomical requirements for Irish grasslands (up to 306 kg ha -1 year -1 ). In the summer of 2003, the site had a significantly higher soil temperature, lower WFPS and lowest rainfall of all years. Large N 2 O emission events followed rainfall after a long dry period in the summer of 2003, attributed to dominant nitrification processes. Furthermore, in the non summer periods, when temperature was lower and WFPS was higher and when there were prior N applications, lower N 2 O emissions occurred and were attributed to dominant denitrification processes. Throughout the study period, the N input and soil dryness related factors (duration of WFPS under 50%, summer average WFPS, and low rainfall) showed exponential relationships with N 2 O emission and the ratio of N 2 O emission to N input. Based on these findings, we infer that the observed anomalously high N 2 O emission in 2003 may have been caused by the combined effects of excess N input above the plant uptake rate, elevated soil temperature, and N 2 O flux bursts that followed the rewetting of dry soil after an unusually long dry summer period. These results suggest that high N input above plant uptake rate and extended dry periods may cause abnormal increases in N 2 O emissions.

“…Soil emission of NO has been determined by the dynamic chamber method as described in Horváth et al (2006). The installation of the chambers, the sampling protocol and the concentration measurement by Horiba APNA/APOA 350 instruments were described earlier in Machon et al (2010).…”

“…As the rate of sedimentation (deposition by gravitation) is proportional to the size the ammonium has lower deposition velocity rate than nitrate, in accordance with the deposition velocities recommended by Borrell et al (1997) and Gallagher et al (2002) for nitrate and ammonium ions, respectively (Table 2). 1 300 301 302 303 304 305 306 307 308 309 310 311 312 Soil N 2 O flux was measured by weekly samplings during non-freezing periods (between 2006 and 2010) using 8 parallel static soil chambers (A=0.25 m 2 ; h=5 cm) (Christensen et al 1996;Clayton et al 1994;Horváth et al 2006).
