Summary: This study investigated the effects of different fertilizers on N2O emissions and productivity in sugarcane crops. The results showed that a nitrification inhibitor coated urea significantly reduced N2O emissions compared to conventional urea, while a blend of polymer coated urea and conventional urea had no significant effect on N2O emissions.

Summary: The study aimed to investigate the combined effects of organic manure and nitrification inhibitor on nitrogen transformation, nitrous oxide emissions, and gene abundance of ammonia oxidizers in acidic and alkaline soils. The results demonstrated that the addition of nitrapyrin along with organic amendment effectively reduced N2O emissions and improved N recovery and utilization in both types of soils. Nitrapyrin significantly inhibited the gene abundance of ammonia-oxidizing bacteria in alkaline soil and inhibited the growth of ammonia-oxidizing archaea in acidic soil.

Summary: Based on an analysis of the current situation of nitrogen fertiliser application, it is suggested that improving the nitrogen utilisation efficiency of crops is an important means of promoting the sustainable development of agriculture and realising the zero increase in chemical fertiliser application. This can be achieved through the release of biological nitrification inhibitors (BNIs), which significantly improve crop yield, increase nitrogen utilisation rate, and reduce greenhouse gas emissions.

Summary: Nitrogen addition to croplands greatly increases global emissions of the potent greenhouse gas nitrous oxide (N2O). The relative contributions of different ammonia oxidizer guilds to N2O production in agricultural soils are still poorly understood. This study found that comammox Nitrospira play only a minor role in N2O emissions in a heavily fertilized alkaline arable soil.

Summary: The study quantified the effects of DCD on nine nitrogen availability metrics in two soils, revealing that the reduction efficiencies for NO3--associated production variables decreased linearly with temperature, while inhibition of NO2- and NO gas production was less sensitive to temperature.

Summary: The study found that nitrification inhibitors significantly reduce N2O emissions and improve water quality and soil health by enhancing total microbial activity and reducing environmental stress on the microbes. While these inhibitors can reduce nitrogen loss, they have minimal impact on pasture biomass yields.

Summary: Nitrogen fertilization is the main source of nitrous oxide (N2O) emissions in agricultural soils, but the reasons for the varied response of N2O emissions to N fertilizer are not clear. This study investigated the effects of ammonium-based fertilizers and nitrification inhibitors on N2O emissions in upland agricultural soils in northern China. The results showed that the variations in N2O emissions were strongly correlated with soil nitrite dynamics, and that alkaline soils had higher ammonia oxidation potential and higher N2O emissions.

Summary: This study examines the impact of different agricultural management strategies on climate change. The results indicate that the use of digestate fertilizer in quinoa cultivation leads to higher greenhouse gas emissions, while yield and biomass production do not significantly differ with increasing nutrient application.

Summary: This study quantifies the production and consumption pathways of N2O in soil using labelled substrate-N, showing the impact of different water filled pore space on N-transformation processes and emissions. The research highlights the importance of heterotrophic nitrification and denitrification in the N2O emissions, demonstrating the complex relationship between water filled pore space and nitrogen transformations.

Summary: Syringic acid (SA) is an effective biological nitrification inhibitor with significant inhibition on Nitrosomonas strains. The inhibitory effect of SA on nitrification and N2O emissions varies in different soils and is correlated with soil pH and clay percentage. SA addition greatly reduces N2O emissions and inhibits the abundance of ammonia-oxidizing archaea and ammonia-oxidizing bacteria in paddy and red soils.

Summary: The addition of urease inhibitor NBPT to urea fertilizers can reduce ammonia emissions, while nitrification inhibitors may lead to an increase in ammonia emission. Factors such as dose and date of application, method of application, type of soil and pH, as well as atmospheric conditions, also have an impact on ammonia emissions.

Summary: The meta-analysis in this study showed that nitrification inhibitors significantly reduced N2O emissions and increased soil NH4+ concentrations, especially when 3,4-dimethylpyrazole phosphate (DMPP) was used in alkaline soils. AOB played a major role in nitrification and could serve as the best predictor of NI efficiency.

Summary: Nitrification inhibitors have shown effectiveness in reducing soil nitrous oxide and nitric oxide emissions from nitrogen-fertilized croplands, but their impact is limited during the spring thaw period, resulting in overall neutral effects for the whole year.

Summary: The study highlights that rainfall and irrigation can lead to large pulses of N2O emissions from intensively managed pastures, emphasizing the need to determine the magnitude and sources of N2O under such conditions. Different pathways of N2O production respond differently to wetting, with denitrification being the main pathway even at low water-filled pore space levels. Heterotrophic nitrification plays a significant role in N2O emissions, especially as wetting increases.
