“…While this was probably true for UAN without nitrapyrin, a slower nitrification rate with nitrapyrin application was probably due more to the fact that nitrapyrin application reduced the initial population of nitrifiers (as evidenced by the significant lag time at Haubstadt in 2011) and/or slowed nitrifier recovery rather than to whether the absolute quantity of N was sufficient or not. In similar experiments, Carneiro et al (2010) and O’Callaghan et al (2010) found that DCD reduced the nitrification rate because it decreased the NH 4 + –oxidizing microbial population and activity without disrupting their composition and not necessarily because of soil N concentration changes.…”

Simultaneous application of nitrification inhibitors and fertilizer N has the potential to delay nitrification processes and reduce atmospheric N loss through N 2 O emissions. A 2-yr study was conducted to assess the effects of newly available water-soluble nitrapyrin (Instinct) [2-chloro-6-(trichloromethyl)pyridine] on the nitrification kinetics and N 2 O emissions from urea-NH 4 NO 3 (UAN) band applied to somewhat poorly drained and moderately well-drained silt loam soils in Indiana. The UAN fertilizer, with or without nitrapyrin, was injected post-emergence between corn (Zea mays L.) rows that were 76 cm apart. Soil samples were taken at various increments from the band centers at 1-to 2-wk intervals for up to 14 wk and analyzed for NH 4and NO 3 -N concentrations. Nitrification rates were determined using appropriate kinetic models. Greenhouse gas samples were collected weekly for 7 to 10 wk and biweekly thereafter for an additional 2 to 4 wk. Our results showed that UAN nitrification followed first-order kinetics, with significantly greater nitrification rate constants without nitrapyrin. On average, UAN half-life was about 15 d without nitrapyrin and 25 d when coapplied with nitrapyrin. Nitrapyrin reduced N 2 O emissions by up to 44% from sidedress-applied UAN, even though emission quantities varied by location and year due to differences in soil moisture, temperature, and precipitation. These latter variables plus soil NH 4 -N concentrations, in various combinations, accounted for 40 to 50% of the total variability associated with N 2 O emissions. These results can help inform UAN management decisions with regard to use of N stabilizers with UAN in the midwestern United States.

The use of nitrification inhibitors (NI) is a technique which is able to improve N fertilizer use efficiency, to reduce nitrate leaching and to decrease the emission of the climate-relevant gas N 2 O simultaneously, particularly in moderately fertilized agricultural systems adapted to plant N demand. The ammonia monooxygenase (AMO) is the first enzyme which is involved in the oxidation of NH þ 4 to NO À 3 in soils. The inhibition of the AMO by NIs directly decreases the nitrification rate and it reduces the NO À 3 concentration which serves as substrate for denitrification. Hence, the two main pathways of N 2 O production in soils are blocked or their source strength is at least decreased. Although it has been shown that archaea are also able to oxidize NH 3 , results from literature suggest that the enzymatic activity of NH 3 oxidizing bacteria is the most important target for NIs because it was much stronger affected. The application of NIs to reduce N 2 O emissions is most effective under conditions in which the NI remains close to the N-fertilizer. This is the case when the NI was sprayed on mineral-N fertilizer granules or thoroughly mixed with liquid fertilizers. Most serious problems of spatial separation of NI and substrate emerge on pasture soils, where N 2 O hotspots occur under urine and to a lesser extent under manure patches. From the few studies on the effect of different NI quantities it seems that the amount of NI necessary to reduce N 2 O emissions is below the recommendations for NI amounts in practice. NIs can improve the fertilizer value of liquid manure. For instance, the addition of NIs to slurry can increase N uptake and yield of crops when NO À 3 -N leaching losses are reduced. It has clearly been demonstrated that NIs added to cattle slurry are very effective in reducing N 2 O as well as NO emissions after surface application and injection of slurry into grassland soils. In flooded rice systems NIs can reduce CH 4 emission significantly, whereas the effect on CO 2 emission is varying. On the other hand, as an effect of the delay of nitrification by NIs, NH 3 emission might increase when N fertilizers are not incorporated into the soil. As compared to other measures NIs have a high potential to reduce N 2 O emissions from agricultural soils. Further, no other measure has so consistently been proofed according its efficiency to reduce N 2 O emissions. From the published data [Akiyama et al. (2010) and more recent data from the years 2010-2013; 140 data sets in total] a reduction potential of approx. 35% seems realistic; however, further measurements in different management systems, particularly in regions with intense frost/thaw cycles seem necessary to confirm this reduction potential. These measurements generally should cover a whole annual cycle.

“…In 2014, nontreated UAN amounts (Table 5) needed to be increased to 147 kg N ha -1 (8%) and 151 kg N ha -1 (11%) in order to obtain yields similar to pronitridine at 9.4 L ha -1 and nitrapyrin, respectively (Figure 1). The increase in the yield may be due reduced gaseous N loss in the presence of the nitrification inhibitors (Bronson et al, 1992;Zaman et al, 2009;Chen et al, 2010;Halvorson et al, 2010;Carneiro et al, 2010;Khalil, 2011;Di & Cameron, 2012;Burzaco et al, 2013;Omonode & Vyn 2013). This could be because spring conditions generally were wet (Table 3), gaseous N losses in claypan soils as high as 30% have been reported (Wilkison et al, 2000), and summer conditions were favorable for high yields.…”

“…In a recent meta-analysis of enhanced efficiency fertilizers for corn management systems, nitrapyrin or NBPT plus DCD combined with UAN showed no significant effect (P = 0.84) on corn yield data (Cook et al, 2015). However, nitrapyrin and DCD have reduced N 2 O emissions 20 to 90% (Chen et al, 2010;Di & Cameron, 2012;Halvorson et al, 2010;Carneiro et al, 2010;Khalil, 2011;Burzaco et al, 2013;Omonode & Vyn, 2013), which can enhance the efficiency of a UAN application.…”

Nitrification inhibitors have been used to enhance the efficiency of nitrogen fertilizers. This research evaluated the effectiveness of nontreated urea ammonium nitrate (UAN) at 0, 67, 135, 202, and 270 kg N ha -1 as well as UAN treated with nitrification inhibitors (pronitridine at 9.4 and 18.8 L ha -1 or nitrapyrin at 0.5 kg a.i. ha -1 ) to enhance N uptake and increase yield of corn (Zea mays L.). The study took place from 2012-2014 in upstate Missouri on a claypan soil. During the experiments, environmental conditions (high, medium, and low yielding years) affected corn response to pronitridine and nitrapyrin. In general, UAN plus pronitridine at 9.4 L ha -1 had similar effects on corn compared pronitridine at a higher (18.7 L ha -1 ) rate. During a high-yielding year (2014), in order to produce yields equivalent to 67 kg N ha -1 plus pronitridine at 9.4 L ha -1 or nitrapyrin, UAN needed to be increased 14 to 19%. Similarly, the amount of nontreated UAN needed to be increased 8 to 11% for yields to be equivalent to UAN at 135 kg N ha -1 plus pronitridine at 9.4 L ha -1 or nitrapyrin. Grain N removal and agronomic efficiency was highest with pronitridine at 9.4 L ha -1 and nitrapyrin combined with 67 and 135 kg N ha -1 , respectively. This research indicates that pronitridine was as effective as nitrapyrin when added to a pre-emergence application of UAN placed between the rows in a dribble band.
