“…These findings suggested that MI increased bacterial community richness and diversity during composting, consistent with previous studies [57]. A previous study by Jiang et al [58] showed that the taxonomic richness of the nirS gene was eight times higher than that of the amoA gene during composting of pig manure and sawdust using N fertilizer synergists. AmoA and nirS genes play critical roles in nitrification and denitrification, which are closely linked to N transformation and NH 3 and N 2 O emissions in the composting process [19].…”

The large-scale generation of vegetable waste in China has become a significant environmental concern. The traditional method of composting results in high nitrogen losses during the process and in the final product. To address this issue and shorten the composting period, this study investigated the effects of bamboo vinegar (BV) and a microbial inoculant (MI) on the physical and chemical properties of the compost and bacterial community composition during the composting process. The results revealed that the addition of BV and BV + MI decreased the time required to reach thermophilic temperatures and conserved nitrogen in the final product. Furthermore, it was found that the dominant nitrifying and denitrifying bacteria, as identified through 16S rDNA analysis, belonged to Nitrosomonas and Proteobacteria, respectively. BV and BV + MI reduced NH3 and N2O emissions, which suggested that BV is a beneficial composting agent that preserves nitrogen during the composting process.

“…Despite debates on NH 3 emissions, nitrification inhibitors are proven to reduce N 2 O and N 2 emissions, effectively offsetting overall nitrogen loss. Research indicates that when nitrification inhibitors are combined with urease inhibitors [103] or solid particles like natural zeolites [104], phosphate rocks such as struvite crystals [102], phosphogypsum [105], etc., they can effectively reduce both NH 3 and N 2 O emissions during composting.…”

Nitrification inhibitors are essential in agricultural and environmental production practices. They play a crucial role in promoting agricultural and environmental sustainability by enhancing nitrogen use efficiency, boosting crop yields, and mitigating the adverse environmental effects of nitrogen losses. This bibliometric analysis covers the period from 2004 to 2023, offering a detailed examination of the development of nitrification inhibitor research. The study demonstrates a consistent growth in research publications, indicating sustained interest and dedication to advancing the field. It identifies key contributors, such as institutions and researchers, and underscores the significance of their work through citation analysis. Keyword co-occurrence analysis reveals four distinct clusters focusing on enhancing crop yields, understanding microbial community dynamics, exploring grazing pasture applications, and addressing environmental impact mitigation. The cutting-edge area of keyword burst detection research has transitioned from fundamental research to comprehensive nitrogen management practices. This analysis provides insights into the current research landscape of nitrification inhibitors and proposes future research directions, underscoring the critical role of this field in tackling global agricultural and environmental challenges.

“…Yang et al [ 24 ] and Yuan et al [ 82 ] conducted similar studies on the combined effect of DCD and other phosphorus compounds. Jiang et al [ 121 ] reported that a “dicyandiamide + thiophosphoric triamide” treatment significantly mitigated the emissions of N 2 O and NH 3 by 63.9% and 26.3%, respectively. The phosphorus additive and DCD caused stronger accumulation of nitrogen in the form of ammonium nitrogen, and the combined treatments exhibited a higher NH 4 + content.…”

Composting is a promising technology for treating organic solid waste. However, greenhouse gases (methane and nitrous oxide) and odor emissions (ammonia, hydrogen sulfide, etc.) during composting are practically unavoidable, leading to severe environmental problems and poor final compost products. The optimization of composting conditions and the application of additives have been considered to mitigate these problems, but a comprehensive analysis of the influence of these methods on gaseous emissions during composting is lacking. Thus, this review summarizes the influence of composting conditions and different additives on gaseous emissions, and the cost of each measure is approximately evaluated. Aerobic conditions can be achieved by appropriate process conditions, so the contents of CH4 and N2O can subsequently be effectively reduced. Physical additives are effective regulators to control anaerobic gaseous emissions, having a large specific surface area and great adsorption performance. Chemical additives significantly reduce gaseous emissions, but their side effects on compost application must be eliminated. The auxiliary effect of microbial agents is not absolute, but is closely related to the dosage and environmental conditions of compost. Compound additives can reduce gaseous emissions more efficiently than single additives. However, further study is required to assess the economic viability of additives to promote their large-scale utilization during composting.
