The accurate estimation of nitrogen (N) and carbon (C) emissions from manures is vital to reduce environmental pressures agriculture. Existing models methods that calculate gaseous often overlook the variations between manures. Consequently, commonly accepted emission factors for ammonia (NH3), methane (CH4), nitrous oxide (N2O), dioxide (CO2) lack precision. We hypothesized variation in slurry manure properties significantly affects N C emissions. conducted a comprehensive mesocosm study with 50 different dairy slurries under controlled conditions. primary objective was understand relation composition used gas monitoring statistical analyses reveal relationship Both cattle direct NH3 CH4 these varied strongly. Multiple linear regression showed pH total ammoniacal content (TAN) were main controlling slurry, while inherent dictated after soil application. pH, contents TAN, organic N, dry matter related N2O injected into soil, water input showing significant effects surface results this indicate as inventories, farm management tools, can be improved by incorporation other readily accessible information, such TAN content, C/N ratio content. Moreover insights measured, creates room reduction practice.

Biofertilizers have immense potential for enhancing agricultural productivity. However, there is still a need clarification regarding the specific mechanisms through which these biofertilizers improve soil properties and stimulate plant growth. In this research, bacterial agent was utilized to enhance growth investigate microbial modulation mechanism of nutrient turnover using metagenomic technology. The results demonstrated significant increase in fast-acting nitrogen (by 46.7%) phosphorus 88.6%) upon application agent. This finding suggests that stimulated microbes contribute enhanced transformation, ultimately leading improved Furthermore, had notable impact on accumulation key genes involved cycling. Notably, it nitrification (amo, hao, nar), while denitrification (nir nor) showed slight decrease. indicates ammonium oxidation may be primary pathway increasing soils. Additionally, influenced composition functional structure community. Moreover, metagenome-assembled genomes (MAGs) obtained from communities exhibited complementary metabolic processes, suggesting mutual exchange. These MAGs contained widely distributed highly abundant encoding promotion (PGP) traits. findings emphasize how can vegetation by availability regulating hormone production. effect further introducing inoculated agents. conclusion, study provides novel insights into underlying beneficial effects availability, cycling, presence PGP traits highlight practices. important implications sustainability productivity, with positive societal environmental impacts.

Abstract Increasing nitrogen (N) input has been recognized as one of the important factors influencing methane (CH4) uptake and nitrous oxide (N2O) emission in arid semiarid grasslands. Numerous studies have examined spatiotemporal variations CH4 N2O fluxes various ecosystems; however, variation interplay between with increasing N not yet well understood. This study explored relationship a grassland Inner Mongolia, northern China, under gradient 12-year additions. We found synergistic at low-N levels, where are positively correlated. Conversely, an antagonistic interaction emerged negative correlation observed high-N which was evidenced by 33.62% decrease 264.91% increase emission. Further independent analysis, covering least five addition levels across ecosystems confirmed general pattern: three four cases showed levels. Given deposition future, dynamics critical for understanding impact external on net greenhouse gas consequent global climate change.
