Summary: Crop residues can significantly affect soil emissions of N2O and other trace gases, with factors such as residue properties, N content, and C/N ratio influencing the emissions. Incorporation of residues into soil leads to sharp initial emissions, which quickly return to background levels within days.

Summary: The study demonstrated that N2O production rates increased significantly with the addition of NH4NO3 in both forest and agricultural soils, although the increase was lower in forest soil. The δN-15(bulk) of N2O produced in forest soil became progressively enriched with more NH4NO3, while becoming more depleted in agricultural soil. Additionally, the N2O site preference (SP) values increased with NH4NO3 in both soils, suggesting a change in N2O contributions.

Summary: Soil nitrous oxide (N2O) is a potent greenhouse gas that is strongly stimulated by rising temperature. The temperature sensitivity of N2O emissions varies among soils with different textures and may be influenced by the abundance of denitrifiers and the content of organic nitrogen and nitrate.

Summary: Soil erosion affects 20% of croplands worldwide, but the understanding of the effect of soil erosion on N2O emissions is limited. Previous studies have neglected the small-scale differences in soil properties induced by erosion, which may have an impact on N2O emission. Our investigations aimed to explore the indications that the erosion state itself strongly influences N2O emission.

Summary: Paddy fields are significant sources of N2O emissions due to frequent fluctuations in soil water content. The contribution of N2O uptake to the reduction in net N2O emission varies with water content and is influenced by physicochemical factors and microbial regulatory mechanisms. However, the specific impact of these factors on N2O uptake in paddy soil remains largely unknown.

Summary: This study found that the end water content of soil was more important than drought severity in determining N2O emissions after rewetting dry soil. Additionally, nitrification was likely the main pathway for N2O production in soil with 90% water-holding capacity after rewetting.

Summary: In a wheat-mungbean-rice rotation system, nitrous oxide emissions were higher in strip tillage compared to conventional tillage, with the nitrogen fertilizer rate also affecting emissions. However, strip tillage could improve soil aggregation and balance nitrogen and crop yield despite the increased emissions.

Summary: Understanding the niche segregation of AOA and AOB in ammonia oxidation and N2O production under different pH and temperature conditions is crucial for predicting N2O dynamics. Results showed that AOA and AOB occupied different niches for PAO, with soil temperature being a major determinant. N2O fluxes were higher in acidic conditions and lower in alkaline conditions, with a significant positive correlation between PAO and N2O fluxes.

Summary: Soil acidification globally impacts soil nitrogen transformation, but its effects on net N mineralization, nitrification, and N2O emissions remain unclear. This study found that soil acidification significantly reduced net N mineralization, net nitrification, and N2O emissions, with the strongest effects observed in soils with pH 5.5. The decrease in net nitrification was attributed to limited N availability and reduced abundance of nitrifying microbes, while the decrease in N2O emissions resulted from suppressed nitrification and denitrification processes and limited N availability. These findings enhance our understanding of soil acidification's effects on N cycling and provide guidance for sustainable N management and N2O mitigation in acid soils.

Summary: Nitrous oxide (N2O) is an important greenhouse gas, and it is mainly emitted and absorbed by soils. This study investigated the effects of soil pH on N2O emission and uptake. The results showed that low soil pH inhibits the nosZ genes involved in N2O consumption, while N2O uptake is not affected. Furthermore, there is evidence of N2O absorption at the soil-atmosphere interface.

Summary: The study revealed that heavy rainfall in the middle of the growing season can increase soil N2O emissions and reduce soil total N content, while heavy rainfall later in the season does not have the same effects. Timing of heavy rainfall events during the plant growing season strongly influences their impacts on soil N fluxes and pools.

Summary: Climate extremes, such as droughts and floods, have intensified and become more frequent due to climate change. This study examines the relationship between stable nitrogen isotopic composition in tree rings and climate extremes and bushfires, in the context of nitrogen cycling in forest ecosystems. The findings suggest that tree ring delta N-15 has the potential to quantify the intensity and frequency of climate extremes and bushfires, but further research is needed to confirm this in different forest ecosystems.
