“…For example, in China soil acidification driven by the GN is at least 10–100 times greater than acid deposition (Guo et al, 2010). The acidity induced via GN is neutralized through accelerating calcium carbonate dissolution (Elrys et al, 2020; Sanderman, 2012). Dissolution of calcium carbonate via this anthropogenic acidity source leads to CO 2 efflux (Zamanian et al, 2018).…”

“…For example, GHN is a major pathway of N 2 O production at low soil pH and high organic C availability (Wrage et al, 2001), while GAN is the main pathway to total N 2 O production in intensively managed calcareous soils with a low soil organic C content (Wan et al, 2009). Furthermore, studies reported that calcium carbonate dissolution by H + ions released as a result of the nitrification process in the absence of root respiration and relatively reduced microbial activity is a factor of carbon dioxide (CO 2 ) emissions (Elrys et al, 2020; Raza et al, 2021). Inhibition of nitrification by inhibitors such as dicyandiamide released less H + ions, reducing CO 2 emissions (Elrys et al, 2020; Raza et al, 2021).…”

Soil gross nitrification (GN) is a critical process in the global nitrogen (N) cycle that results in the formation of nitrate through microbial oxidation of ammonium or organic N, and can both increase N availability to plants and nitrous oxide emissions. Soil GN is thought to be mainly controlled by soil characteristics and the climate, but a comprehensive analysis taking into account the climate, soil characteristics, including microbial characteristics, and their interactions to better understand the direct and indirect controlling factors of GN rates globally is lacking. Using a global meta‐analysis based on 901 observations from 330 15N‐labeled studies, we show that GN differs significantly among ecosystem types, with the highest rates found in croplands, in association with higher pH which stimulates nitrifying bacteria activities. Autotrophic and heterotrophic nitrifications contribute 63% and 37%, respectively, to global GN. Soil GN increases significantly with soil total N, microbial biomass, and soil pH, but decreases significantly with soil carbon (C) to N ratio (C:N). Structural equation modeling suggested that GN is mainly controlled by C:N and soil total N. Microbial biomass and pH are also important factors controlling GN and their effects are similar. Precipitation and temperature affect GN by altering C:N and/or soil total N. Soil total N and temperature drive heterotrophic nitrification, whereas C:N and pH drive autotrophic nitrification. Moreover, GN is positively related to nitrous oxide and carbon dioxide emissions. This synthesis suggests that changes in soil C:N, soil total N, microbial population size, and/or soil pH due to anthropogenic activities may influence GN, which will affect nitrate accumulation and gaseous emissions of soils under global climate and land‐use changes.

“…Results of a 3-year field study showed that application of DCD decreased CO 2 emissions by 7% (Weiske et al, 2001). Another study reported that DCD minimizes CO 2 emission from acidic soils (Elrys et al, 2020). Similarly, Raza et al (2021) also stated that DCD significantly decreased CO 2 emissions from calcareous soils.…”

Controlled-release nitrogen fertilizers (CRF) are widely used in agricultural production to reduce conventional fertilization-induced agricultural greenhouse gas emissions. However, the long-term effects and associated mechanisms remain unclear. Therefore, this study investigated variations in agricultural greenhouse gas emissions at different growth stages under treatments of zeolite with CRF based on a 5-year field experiment. Results showed that both annual and yearly cumulative N O and CO emissions were significantly reduced across all the three treatments relative to control. The treatment of nitrification inhibitor-controlled release N fertilizer with zeolite (T4) performed the best, followed by CRF (T3). Both the peak N O and CO emissions occurred at the lotus stage. The crop nitrogen content of control was reduced by 12.5%, while the nitrogen content of other treatments was reduced by 5.90% to 11.4%. The T4 treatment delayed the oxidation of NH and reduced CO emissions. The N O and CO emission reductions significantly descended and then the decrement narrowed with the planting years increasing. Therefore, using blended controlled-release N fertilizer with zeolite to reduce chemical N application is a practically and environmentally friendly approach for greenhouse gases emissions reduction in the lettuce rotation system.

“…It has been well documented that nitrapyrin suppressed soil nitrification rates through deactivating soil ammonia monooxygenase (AMO, EC 1.14.99.39), inhibiting the abundances, diversities, and community structures of both ammonia-oxidizing archaea (AOA) and bacteria (AOB). NIs 3,4-dimethylpyrazole phosphate (DMPP) and dicyandiamide (DCD) exerted significant effects on suppressing soil carbon decomposition and decreasing soil carbon dioxide (CO 2 ) emissions. − Raza et al noted that DCD addition effectively minimized CO 2 emissions from a calcareous soil, while Weiske et al found that a consecutive 3 year application of DMPP and DCD significantly reduced CO 2 release by 7 and 28%, respectively, from a clayey loam soil. Similarly, Maris et al reported that the cumulative CO 2 emission from an olive orchard was significantly decreased by DMPP application.…”

Application of nitrification inhibitors (NIs) has been widely used to inhibit nitrification and reduce N2O emissions. However, the impacts of NI addition on soil carbon transformation and carbon-degrading microbial communities have not been well explored. Here, a microcosm experiment was carried out, and four treatments were designed: (i) unfertilized control, (ii) urea alone, (iii) urea plus cattle manure, and (iv) urea plus cattle manure with nitrapyrin. The influence of nitrapyrin on soil CO2 emissions, carbon-degrading extracellular enzyme activities, and the abundance and diversity of the cbhI community was investigated. Compared to the treatment of urea plus cattle manure, nitrapyrin significantly decreased cumulative CO2 emissions by 51.8%. Moreover, cbhI community gene copies and their α-diversities (P < 0.05) were also significantly reduced by nitrapyrin application. A partial least squares path model showed that CO2 emission was positively associated with cbhI community α-diversity but negatively associated with nitrapyrin addition. We conclude that the mitigation of soil CO2 emissions by nitrapyrin can be ascribed to its effects on decreasing of cellulose-degrading gene community diversity. Our findings provide new insights into the side-effects of nitrapyrin on abating CO2 emission.
