“…These are considered to be effective in reducing the masking effects of soil temperature and water conditions on N 2 O and CO 2 production, enabling the effects of other soil factors to be determined (Gödde and Conrad 2000). The reason for the largest N 2 O production in orchard soils might be the high initial mineral N levels according to chronic fertilizer application in the fields, which is considered a key factor influencing N 2 O emissions (Robertson et al 2000;Mathieu et al 2006). Land use types may directly alter soil properties, especially the biological properties (Merino et al 2004), and thus indirectly affect GHG emission (Ishizuka et al 2002).…”

Land-use type and nitrogen (N) addition strongly affect nitrous oxide (N 2 O) and carbon dioxide (CO 2 ) production, but the impacts of their interaction and the controlling factors remain unclear. The aim of this study was to evaluate the effect of both factors simultaneously on N 2 O and CO 2 production and associated soil chemical and biological properties. Surface soils (0-10 cm) from three adjacent lands (apple orchard, grassland and deciduous forest) in central Japan were selected and incubated aerobically for 12 weeks with addition of 0, 30 or 150 kg N ha. Land-use type had a significant (p < 0.001) impact on the cumulative N 2 O and CO 2 production. Soils from the apple orchard had higher N 2 O and CO 2 production potentials than those from the grassland and forest soils. Soil net N mineralization rate had a positive correlation with both soil N 2 O and CO 2 production rates. Furthermore, the N 2 O production rate was positively correlated with the CO 2 production rate. In the soils with no N addition, the dominant soil properties influencing N 2 O production were found to be the ammonium-N content and the ratio of soil microbial biomass carbon to nitrogen (MBC/MBN), while those for CO 2 production were the content of nitrate-N and soluble organic carbon. N 2 O production increased with the increase in added N doses for the three land-use types and depended on the status of the initial soil available N. The effect of N addition on CO 2 production varied with land use type; with the increase of N addition doses, it decreased for the apple orchard and forest soils but increased for the grassland soils. This difference might be due to the differences in microbial flora as indicated by the MBC/MBN ratio. Soil N mineralization was the major process controlling N 2 O and CO 2 production in the examined soils under aerobic incubation conditions.

“…It was assumed that the chemical and biological reactions that cause N 2 O emissions take place in a small soil area; large plots would not bring additional benefit because of the high spatial variability of N 2 O emissions in soils (Mathieu et al, 2006). The experiment followed a complete randomized design with four replications, resulting in 20 plots and 20 chambers.…”

Enhanced-Efficiency Fertilizers in Nitrous Oxide Emissions from Urea Applied to Sugarcane

The environmental benefits of producing biofuels from sugarcane have been questioned due to greenhouse gas emissions during the biomass production stage, especially nitrous oxide (N 2 O) associated with nitrogen (N) fertilization. The objective of this work was to evaluate the use of nitrification inhibitors (NIs) dicyandiamide (DCD) and 3,4 dimethylpyrazole phosphate (DMPP) and a controlled-release fertilizer (CRF) to reduce N 2 O emissions from urea, applied at a rate of 120 kg ha -1 of N. Two field experiments in ratoon cycle sugarcane were performed in Brazil. The treatments were (i) no N (control), (ii) urea, (iii) urea+DCD, (iv) urea+DMPP, and (v) CRF. Measurements of N 2 O fluxes were performed using static chambers with four replications. The measurements were conducted three times per week during the first 3 mo and biweekly afterward for a total of 217 and 382 d in the first and second seasons, respectively. The cumulative N 2 O-N emissions in the first ratoon cycle were 1098 g ha -1 in the control treatment and 1924 g ha -1 with urea (0.7% of the total N applied). Addition of NIs to urea reduced N 2 O emissions by more than 90%, which did not differ from those of the plots without N. The CRF treatment showed N 2 O emissions no different from those of urea. The results were similar in the second ratoon: the treatment with urea showed N 2 O emissions of 0.75% of N applied N. Application of NIs resulted in a strong reduction in N 2 O emissions, but CRF increased emissions compared with urea. We therefore conclude that both NIs can be options for mitigation of greenhouse gas emission in sugarcane used for bioenergy.

“…Although the final product of denitrification is the benign atmospheric gas N 2 , this process is not always completed and variable amounts of N 2 O, a potent greenhouse gas (GHG), can be produced. Physical, chemical and biological factors influence the reduction of N 2 O to N 2 (Weier et al, 1993) including soil moisture content (Davidson, 1991;Ruser et al, 2006), pH (Simek and Cooper, 2002;Cuhel et al, 2010), temperature (Bailey, 1976;Keeney et al, 1979), C supply (Parkin, 1987;Mathieu et al, 2006), soil redox conditions (Firestone and Tiedje, 1979;Tiedje, 1988) and management (Frolking et al, 1998;Liu et al, 2007).…”

The effect of cattle slurry in combination with nitrate and the nitrification inhibitor dicyandiamide on in situ nitrous oxide and dinitrogen emissions

Abstract.A field study was conducted to determine the effect of the nitrification inhibitor dicyandiamide (DCD) on N 2 O and N 2 emissions after cattle slurry (CS) application in the presence of nitrate (NO 3 ) fertiliser on seven different occasions (between March 2009 and March 2011). N 2 O emissions from CS in the presence of NO 3 fertiliser were very high (0.4-8.7 % of applied N) over a 20-day period, under mild moist conditions. Emissions were significantly larger from the CS treatment compared to an NH + 4 -N source, supplying the same rate of N as in the slurry. This study supports the view that organic fertilisers should not be applied at the same time as nitrate-based fertilisers, as significant increases in N 2 O emissions occur. The average N 2 O mole fraction (N 2 O/(N 2 O + N 2 )) over all seven application dates was 0.34 for CSNO 3 compared to 0.24 for the NH 4 ClNO 3 treatment, indicating the dominance of N 2 emissions.The rate of nitrification in CSNO 3 was slower than in NH 4 ClNO 3 , and DCD was found to be an effective nitrification inhibitor in both treatments. However, as N 2 O emissions were found to be predominantly associated with the NO 3 pool, the effect of DCD in lowering N 2 O emissions is limited in the presence of a NO 3 fertiliser. To obtain the maximum cost-benefit of DCD in lowering N 2 O emissions, under mild moist conditions, it should not be applied to a nitrate containing fertiliser (e.g. ammonium nitrate or calcium ammonium nitrate), and therefore the application of DCD should be restricted to ammonium-based organic or synthetic fertilisers.
