“…In the current investigation, from 33.6 to 56.1 kg N per ha or about 110 to 180 g N per tree was applied 4 times during the growing season (650 g tree À1 season À1 ). In other intensively Nfertilized systems like corn (Qian et al 1997, McSwiney and Robertson 2005, Venterea et al 2005, Mosier et al 2006, Almaraz et al 2009, Lee et al 2009, Adviento-Borbe et al 2010, Halvorson et al 2010 and references therein, Halvorson and Del Grosso 2011) and wheat (see Majumdar et al 2002, Webb et al 2004, Grandy et al 2006, Chirinda et al 2010 the maximum N 2 O emissions observed were in a comparable range. The net fluxes we observed were also in a similar range for instantaneous emissions recently reported for N-intensive vegetable crops , Sánchez-Martín et al 2008).…”

Abstract. Nitrogen fertilizer applied to soil is the primary source of the greenhouse gas (GHG) nitrous oxide (N 2 O). The assessment of N 2 O emissions, or net fluxes of the GHG methane (CH 4 ), are lacking for upland, arid agricultural ecosystems worldwide. In California, where rates of application for nitrogen (N) can exceed 300 kg per hectare for N-intensive fruit and nut crops (.2 million acres), liquid N fertilizers applied through microirrigation systems (fertigation) represent the predominant method of N fertilization. Little information is available for how these concentrated and spatially discrete N solution applications influence N 2 O emissions and net CH 4 fluxes (the sum of methanogenic and methanotrophic activity). In this study we examined soil N 2 O-N emissions and net CH 4 fluxes for drip and stationary microsprinklers, two of the most widely used fertigation emitters, in an almond orchard where 235.5 kg N/ha were applied during the season of measurement (2009)(2010). We accomplished this by modeling the spatial patterns of N 2 O and CH 4 at the scale of meters and centimeters using simple mathematical approaches. For two applications of 33.6 kg/ha and three applications of 56.1 kg/ha targeted to the phenologic stages with highest tree N demand, the spatial patterns of N 2 O fluxes were similar to the emitter water distribution pattern and independent of temperature and fertilizer N form applied. Net CH 4 fluxes were extremely low and there was no discernible spatial pattern, but areas kept dry (driveways between tree rows) generally consumed CH 4 while it was produced in the microirrigation wet-up area. The N 2 O-N emissions for fertigation events at the scale of days, and over a season, were significantly higher from the drip irrigated orchard (1.6 6 0.7 kg N 2 O-N ha À1 yr À1) than a microsprinkler irrigated orchard (0.6 6 0.3 kg N 2 O-N ha À1 yr À1 ). N 2 O emissions and net CH 4 fluxes were only significantly correlated with soil water filled pore space and not with mineral-N. The correlation was much better for N 2 O emissions. Our results greatly improve our ability to scale N 2 O production to the orchard level, and provide growers with a tool for lowering almond orchard carbon and nitrogen footprints.

“…The application of DCD and DMPP together with NH + 4 -based fertilizers, cow urine or cattle slurry has demonstrated efficiency in reducing the N losses in forms of nitrous oxide (N 2 O) emission and NO − 3 leaching while increasing the yield and use efficiency of fertilizer N in croplands and grasslands (Weiske et al, 2001;Majumdar et al, 2002;Zaman et al, 2009;Cui et al, 2011;Di and Cameron, 2012;Moir et al, 2012;Pfab et al, 2012). Compared with DCD, a comparable or even better inhibition effect on N 2 O emission and NO − 3 leaching can be achieved with approximately 1/25 to 1/2 of the application rate for DMPP (Weiske et al, 2001;Belastegui-Macadam et al, 2003;Di and Cameron, 2012).…”

“…There are a variety of new management practices and technologies that can promote N use efficiency and alleviate environmental pollution. One of the mitigation technologies that has proved to be highly effective in reducing fertilizer N losses and increasing N use efficiency and yield in a few cropping systems is the application of nitrification inhibitors (Majumdar et al, 2002;Zaman et al, 2009;Cui et al, 2011;Moir et al, 2012).…”

The application of nitrification inhibitors together with ammonium-based fertilizers is proposed as a potent method to decrease nitrous oxide (N₂O) emission while promoting crop yield and nitrogen use efficiency in fertilized agricultural fields. To evaluate the effects of nitrification inhibitors, we conducted year-round measurements of N₂O fluxes, yield, aboveground biomass, plant carbon and nitrogen contents, soil inorganic nitrogen and dissolved organic carbon contents and the main environmental factors for urea (U), urea + dicyandiamide (DCD) and urea + 3,4-dimethylpyrazol phosphate (DMPP) treatments in a wheat–maize rotation field. The cumulative N₂O emissions were calculated to be 4.49 ± 0.21, 2.93 ± 0.06 and 2.78 ± 0.16 kg N ha⁻¹ yr⁻¹ for the U, DCD and DMPP treatments, respectively. Therefore, the DCD and DMPP treatments significantly decreased the annual emissions by 35% and 38%, respectively (p < 0.01). The variations of soil temperature, moisture and inorganic nitrogen content regulated the seasonal fluctuation of N₂O emissions. When the emissions presented clearly temporal variations, high-frequency measurements or optimized sampling schedule for intermittent measurements would likely provide more accurate estimations of annual cumulative emission and treatment effect. The application of nitrification inhibitors significantly increased the soil inorganic nitrogen content (p < 0.01); shifted the main soil inorganic nitrogen form from nitrate to ammonium; and tended to increase the dissolved organic carbon content, crop yield, aboveground biomass and nitrogen uptake by aboveground plant. The results demonstrate the roles the nitrification inhibitors play in enhancing yield and nitrogen use efficiency and reducing N₂O emission from the wheat–maize cropping system

“…It has been well in the nitrification process (Kelliher et al, 2008). DCD has been shown to effectively reduce N 2 O emissions from pasture (Zaman et al, 2008;Cameron et al, 2014;Robinson et al, 2014), grassland (Di and Cameron, 2003;Di et al, 2010), paddy fields (Kumar et al, 2000;Li et al, 2009) and upland soil (Majumdar et al, 2002;Vallejo et al, 2005;Meijide et al, 2007). Both NO and N 2 O are important byproducts of nitrification; however, only few studies (Vallejo et al, 2005;Meijide et al, 2007) have investigated the reduction effect of DCD for both N 2 O and NO from agricultural fields.…”
