“…However, < 20 mg kg −1 of soil mineral N increase in the 0–15 cm layer due to fertilization frequently led to negligible N 2 O emission (Tables 3 and 4). Similar results were reported in other studies (Vermoesen et al , 1996). Therefore, it is reasonable to conclude that soil mineral N from planting to silking was not a limiting factor to N 2 O emission when N was applied before planting or sidedress at the V6–V8 stage.…”

Nitrogen fertilization is considered as an important source of atmospheric N 2 O emission. A seven site-year on-farm field experiment was conducted at Ottawa and Guelph, ON and Saint-Valentin, QC, Canada to characterize the affect of the amount and timing of N fertilizer on N 2 O emission in corn (Zea mays L.) production. Using the static chamber method, gas samples were collected for 28-days after preplant and 28-days after sidedress fertilization at the seven site-year, resulting in 14 monitoring periods. For both methods of fertilization, peak N 2 O flux and cumulative emission increased with the amount of N applied, with rates ranging from 30 to 900 lg N m À2 h À1 . Depending on N amount and time of application, cumulative emission varied from 0.05 to 2.42 kg N ha À1 , equivalent to 0.03% to 1.45% of the N fertilizer applied. Differences in N 2 O emission peaks among fertilizer treatments were clearly separated in 13 out of 14 monitoring periods. Total N 2 O emissions may have been underestimated compared with annual monitoring in 10 out of the 49 cases because the monitoring period ended before N 2 O efflux returned to the baseline level. The flux of N 2 O was negligible when soil mineral N in the 0-15 cm layer was o20 mg N kg À1 . While rainfall stimulated emission, soil temperature 415 1C was likely the driving force responsible for the higher levels of N 2 O found for sidedress than preplant application methods. However, caution must be taken when interpreting these later results as preplant fertilization may have continuously stimulated N 2 O emissions after the 28-days monitoring period, especially in situations where N 2 O effluxes have not fallen back to their baseline levels. Increasing fertilizer rates from 90 to 150 kg N ha À1 resulted in slight increases in yields, but doubled cumulative N 2 O emissions.

“…Soil acidity is supposed to be an important factor promoting N-losses from forest soils influenced by atmospheric nitrogen deposition (Li et al, 2000 andVenterea et al, 2003). Soils with a pH of 7-8 are supposed to produce higher amounts of N 2 (Simek and Cooper, 2002) but revealed an order of magnitude higher N 2 O emissions than soils with a pH between 4 and 6 (Vermoesen et al, 1996). A soil pH of 6.7-7.1 measured at our limestone site restricts self-decomposition of HNO 2 and might, therefore, be responsible for low NO fluxes (Van Cleemput and Samater, 1996).…”

Abstract. We measured nitrogen oxides (N2O and NOx), dinitrogen (N2) and carbon dioxide (CO2) emissions from a spruce-fir-beech forest soil in the North Tyrolean limestone Alps in Austria. The site received 12.1 kg nitrogen via wet and dry deposition. Fluxes of nitric oxide (NO) were measured by an automatic dynamic chamber system on an hourly basis over a two year period. Daily N2O emissions were obtained by a semi-automatic gas measuring system. In order to cover spatial variability biweekly manual measurements of N2O and CO2 emissions were carried out, additionally. For acquiring information on the effects of soil and meteorological conditions and of N-deposition on N-emissions we chose the autoregression procedure (time-series analysis) as our means of investigation. Hence, we could exclude the data's autocorrelation in the course of the time. We found that soil temperature, soil moisture and wet N-deposition followed by air temperature and precipitation were the most powerful influencing parameters effecting N-emissions. With these variables up to 89% of observed temporal variations of N-emissions could be explained. During the two-year investigation period between 2.5 and 3.5% of deposited N was reemitted in form of N2O whereas only 0.2% were emitted as NO. At our mountain forest site the main end-product of microbial activity processes was N2 and trace gases (N2O and NO) were only of minor importance.

“…ORDER REPRINTS may be due to predominant accumulation of NH 1 4 coupled with a low nitrification (16) as supported by Vermoesen et al (18). Under aerobic conditions, some initial nitrate reductions also indicated an impact of some denitrification to N 2 O peak from anaerobic microenvironments.…”
