Abstract. The potential for elevated nitrous oxide (N 2 O) losses is high in subtropical cereal cropping systems in northeast Australia, where the fertiliser nitrogen (N) input is one single application at or before planting. The use of urea coated with the nitrification inhibitor 3,4-dimethylpyrazole phosphate (DMPP) has been reported to substantially decrease N 2 O emissions and increase crop yields in humid, high-intensity rainfall environments. However, it is still uncertain whether this product is similarly effective in contrasting soil types in the cropping region of north-east Australia. In this study the grain yield response of sorghum (Sorghum bicolor L. Moench) to rates of fertiliser N applied as urea or urea coated with DMPP were compared in crops grown on a Vertisol and an Oxisol in southern Queensland. Seasonal N 2 O emissions were monitored on selected treatments for the duration of the cropping season and the early stages of a subsequent fallow period using a fully automated high-frequency greenhouse gas measuring system. On each soil the tested treatments included an unfertilised control (0 kg N ha -1 ) and two fertilised treatments chosen on the basis of delivering at least 90% of seasonal potential grain yield (160 and 120 kg N ha -1 on the Vertisol and Oxisol respectively) or at a common (suboptimal) rate at each site (80 kg N ha -1 ). During this study DMPP had a similar impact at both sites, clearly inhibiting nitrification for up to 8 weeks after fertiliser application. Despite the relatively dry seasonal conditions during most of the monitoring period, DMPP was effective in abating N 2 O emissions on both soils and on average reduced seasonal N 2 O emissions by 60% compared with conventional urea at fertiliser N rates equivalent to those producing 90% of site maximum grain yield. The significant abatement of N 2 O emissions observed with DMPP, however, did not translate into significant yield gains or improvements in agronomic efficiencies of fertiliser N use. These results may be due to the relatively dry growing season conditions before the bulk of crop N acquisition, which limited the exposure of fertiliser N to large losses due to leaching and denitrification.

“…The variation in N 2 O reduction caused by NIs is explained by the complex combination of factors that affect the action of such compounds in the soils and the drivers of N 2 O emission (e.g., soil pH, organic matter, porosity, temperature, and soil moisture) (Halvorson et al, 2014;Singh et al, 2008;Subbarao et al, 2006;Trenkel, 2010;Vargas et al, 2014;Weiske et al, 2001). For example, Singh et al (2008) showed 90% reduction in N 2 O emissions by the addition of DCD in urine to a soil with low organic carbon (3.4 g kg -1…”

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.

“…NIs are natural or synthetic compounds that inhibit the microbial oxidation of NH 4 + -N to NO 2 − -N, the first step of the nitrification process, and thus reducing nitrogen loss in the form of N 2 or N 2 O caused by denitrification (Yang et al 2013), in which NO 3 − -N and NO 2 − -N are the sources of nitrogen and nitrogen leaching (Yu et al 2007;Yu et al 2014). 3,4-Dimethylpyrazole phosphate (DMPP) is one of the most highly effective NIs (Weiske et al 2001;Zerulla et al 2001). Experiments have been conducted to investigate the effects of DMPP addition on nitrogen transformation (Yu et al 2007), plant productivity (Yu et al 2014), nitrogen transformation functional genes (Kleineidam et al 2011;Florio et al 2014), and chemical parameters (Barneze et al 2014) in soil.…”

However, there is still no information on the degradation of organics after DMPP addition.…”

Sludge composting is one of the most widely used treatments for sewage sludge resource utilization. Natural zeolite and nitrification inhibitor (NI) are widely used during composting and land application for nitrogen conservation, respectively. Three composting reactors (A-the control, B-natural zeolite addition, and C-3,4-dimethylpyrazole phosphate (DMPP) addition) were established to investigate the influence of NI and natural zeolite addition on organics degradation and nitrogen transformation during sludge composting conducted at the lab scale. The results showed that, in comparison with the control, natural zeolite addition accelerated organics degradation and the maturity of sludge compost was higher, while the DMPP addition slowed down the degradation of organic matters. Meanwhile, the nitrogen transformation functional genes including those responses for nitrification (amoA and nxrA) and denitrification (narG, nirS, nirK, and nosZ) were quantified through quantitative PCR (qPCR) to investigate the effects of natural zeolites and DMPP addition on nitrogen transformation. Although no significant difference in the abundance of nitrogen transformation functional genes was observed between treatments, addition of both natural zeolite and DMPP increases the final total nitrogen content by 48.6 % and 23.1 %, respectively. The ability of natural zeolite for nitrogen conservation was due to the absorption of NH 3 by compost, and nitrogen conservation by DMPP was achieved by the source reduction of denitrification. Besides, it was assumed that the addition of natural zeolite and DMPP may affect the activity of these genes instead of the abundance.
