“…Previous studies demonstrated that nitrification was less inhibited in the soils with higher clay and silt content, where DMPP may have been absorbed [40]. The main reason for this discrepancy is the higher pH and lower SOM in the tested soil [38,43]. The sharp increase in NH 3 volatilization was clearly observed in the early days after the application of N fertilizer and NIs during the incubation period in three soils, which could be due to higher NH 4 + [44].…”

“…Aside from soil pH, soil organic matter (SOM) and soil texture have also been recognized as the main factors influencing the effectiveness and the persistence of NIs [29,37]. The adsorption of SOM on NIs reduces its mobility, volatility, bioactivity, and thus their effectiveness, but increases the persistence of NIs due to the sorption of NIs by the SOM [38,39]. NH 4 + -N contents were kept higher in the acid soil during the entire period of incubation than in the two other soils, since the content of SOM in the acid soil (52.25 g kg −1 ) was higher than those in the two other tested soils (32.65 g kg −1 ; 30.12 g kg −1 ), which increased the persistence of NIs.…”

The application of nitrification inhibitors (NIs) is considered to be an efficient way to delay nitrification, but the effect of NIs combinations on soil nitrification and ammonia (NH3) volatilization are not clear in soils with different pH values. In this study, we explored the effect of nitrapyrin (CP) and its combinations with 3, 4-dimethylepyrazole phosphate (DMPP), dicyandiamide (DCD) on the transformation of nitrogen, potential nitrification rate (PNR), and ammonia (NH3) volatilization in a 120-day incubation experiment with three different pH values of black soil. Treatments included no fertilizer (Control), ammonium sulfate (AS), AS+CP (CP), AS+CP+DMPP (CP+DMPP), and AS+CP+DCD (CP+DCD). The application of NIs significantly decreased NO3−-N contents and potential nitrification rate (p < 0.05), while significantly increased NH4+-N contents (p < 0.05), especially CP+DCD and CP+DMPP were the most effective in the neutral and alkaline soils, respectively. In the acid soil, CP significantly increased total NH3 volatilization by 31%, while CP+DCD significantly reduced by 28% compared with AS. However, no significant difference was found in NH3 volatilization with and without NIs treatments (p > 0.05) in the neutral and alkaline soils. In conclusion, the combined nitrification inhibitors had the better efficiency in all three tested soils. CP+DCD and CP+DMPP are the most effective in inhibiting soil nitrification in the clay soils with higher pH value and lower organic matter, while CP+DCD had the potential in mitigating environment pollution by reducing N loss of NH3 volatilization in the loam soil with lower pH value and higher organic matter. It provided a theoretical basis for the application of high efficiency fertilizer in different soils. Further studies under field conditions are required to assess the effects of these nitrification inhibitors.

“…would influence their availability and effectiveness (Zhang et al, 2020;Cui et al, 2021). Furthermore, SOM could be used by soil microorganisms as energy, carbon (C), and N source, which improve microbial bioactivity, leading to accelerated biodegradation of NIs (Fisk et al, 2015).…”

Nitrification inhibitor (NI) is often claimed to be efficient in mitigating nitrogen (N) losses from agricultural production systems by slowing down nitrification. Increasing evidence suggests that ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB) have the genetic potential to produce nitrous oxide (N2O) and perform the first step of nitrification, but their contribution to N2O and nitrification remains unclear. Furthermore, both AOA and AOB are probably targets for NIs, but a quantitative synthesis is lacking to identify the “indicator microbe” as the best predictor of NI efficiency under different environmental conditions. In this present study, a meta-analysis to assess the response characteristics of AOB and AOA to NI application was conducted and the relationship between NI efficiency and the AOA and AOB amoA genes response under different conditions was evaluated. The dataset consisted of 48 papers (214 observations). This study showed that NIs on average reduced 58.1% of N2O emissions and increased 71.4% of soil NH4+ concentrations, respectively. When 3, 4-dimethylpyrazole phosphate (DMPP) was applied with both organic and inorganic fertilizers in alkaline medium soils, it had higher efficacy of decreasing N2O emissions than in acidic soils. The abundance of AOB amoA genes was dramatically reduced by about 50% with NI application in most soil types. Decrease in N2O emissions with NI addition was significantly correlated with AOB changes (R2 = 0.135, n = 110, P < 0.01) rather than changes in AOA, and there was an obvious correlation between the changes in NH4+ concentration and AOB amoA gene abundance after NI application (R2 = 0.037, n = 136, P = 0.014). The results indicated the principal role of AOB in nitrification, furthermore, AOB would be the best predictor of NI efficiency.

“…[17][18][19] Nowadays, the research in this eld is still focused on the following aspects: (1) the comparative analysis of the application effect of nitrapyrin in different soil types and (2) the adsorption characteristics of nitrapyrin on soil with different organic matter contents. For example, Yan et al 20 compared and analyzed the nitrication inhibition effect of nitrapyrin on sandy and clay soils with different organic matter contents, and the overall performance was found to be better on sandy soil than on clay soil; Zhang et al 21 found that the maximum adsorption capacity and adsorption constant of nitrapyrin on black soil before and aer organic matter removal showed a signicant quadratic function correlation. Zhang et al 22 found that the adsorption kinetics of nitrapyrin on black soil, chernozem and planosol could be tted using the quasi-second-order kinetic equation with a lower active energy of adsorption.…”
