“…In the present study, the N 2 O emission was lower in BC than in BB, BD, and CK. A previous study reported that seasonal total N 2 O emissions decreased to a greater extent in response to cattle manure-derived organic fertilizer than to chemical fertilizer (Geng et al 2021), indicating the different effects of fertilizer types on N 2 O emission.…”

Agroforestry systems are widely applied in China and have both economic and ecological benefits. However, relatively few prior studies have investigated the relative ecological benefits of various agroforestry systems. In the present study, the static chamber method, qPCR, and high throughput sequencing were used to establish the differences in greenhouse gases (GHGs) fluxes and explore the bacterial and fungal populations affecting GHGs fluxes under different agroforestry systems, including pure Moso bamboo forest (CK), bamboo+Bletilla striata (BB), bamboo+Dictyophora indusiata (BD), and bamboo+chickens (BC). The highest cumulative CH4 uptake and N2O emission in spring occurred in BB while the highest cumulative CO2 emission and GWP in spring occurred in BC. The Methylomirabilaceae were the key methanotrophs influencing the comparative differences in NO3--associated CH4 uptake among the various agroforestry systems. N2O emission was associated with pH, and nitrifiers such as the ammonia-oxidizing archaea (AOA) and bacteria (AOB) (Nitrospiraceae and Nitrosomonadaceae) rather than denitrifiers may be the key microbes affecting N2O emission in different agroforestry systems. The bacteria Actinobacteriota and Fibrobacteres and the fungi Ascomycetes and Basidiomycota were the primary microbial taxa influencing CO2 emission. The lignin-decomposing Basidiomycota played more important roles in CO2 emission than the cellulose-decomposing fungi and bacteria under the various agroforestry systems. CO2 emission was positively correlated with NO3- in the bacterial community and was negatively correlated with NO3- in the fungal community, implying two C decomposition mechanisms caused by denitrification dominated in bacteria and those caused by microbial nitrogen mining dominated in fungi. The foregoing results suggested that bamboo+B. striata had comparatively higher ecological benefits as it is associated with low GWP and external C fixation. The present study provided valuable information for screening bamboo-based agroforestry systems with high ecological benefits. It also elucidated the microbial mechanism explaining the observed differences in GHGs fluxes between the various agroforestry systems.

“…For reducing the N 2 O emission, several practical methods have been developed and deployed, such as (i) keeping soils in aerobic conditions by optimum irrigation-drainage management, and avoidance of soil compaction by animals or traffic 2 , (ii) using slow release fertilizers 128 , urease inhibitor 129 , or nitrification inhibitor 130 , (iii) incorporating (bio-)organic fertilizers 131 and biochars 132 in soilplant systems, and (iv) sowing legume crops in the fallow period between crop cycles 133 . In particular, the green practice of using inhibitors has been greatly advocated by numerous studies.…”

The use of nitrogen fertilizers in agriculture produces significant quantities of nitrogenous gases including ammonia, nitric oxide, and nitrous oxide. Through better farmland management practices, the emission of nitrogenous gases can be reduced while realizing clean water environment and climate-smart agriculture. In this article, we first provided an overview of the international movements on reducing nitrogenous gas emissions from farmlands. Then, we summarized the effect of agricultural management practices on nitrogen use efficiency for various crops, and evaluated their effect on nitrogenous gas emissions. The results indicated the importance of implementing site-specific sustainable management practices to enhance nitrogen use efficiency, and thus mitigate nitrogenous gas emissions. We also addressed the impact of agricultural activities on cropland nitrogen cycles, and highlighted the need to perform systematic trade-off evaluations with a well-defined scope to maximize environmental benefits and maintain ecosystem services. Lastly, we proposed three priority directions by moving toward a low-emission agriculture.

According to the requirements of different fertilizers for early-maturing and late-maturing broccoli, this study aimed to establish the models of formula fertilization to apply them in the recommendation of fertilization by the aid of soil testing performed in main broccoli-producing areas. In this paper, based on the effective functions of for nitrogen- (N), phosphorous- (P), and potassium (K)-balanced fertilizers for broccoli of two different mature types, the models of formula fertilization were established. The recommend formula fertilization was accomplished in 12 different plots in the same broccoli-producing areas. The analysis of N, P, and K fertilizer contributions to broccoli yield indicated that the application rate of N, P, and K fertilizers for early-maturing variety was higher than that for late-maturing variety, when the yield contribution rate of N, P, and K fertilizers reached the extreme value. The contribution of K fertilization to the yield even had a significantly negative effect with the continuous increase of K fertilizer application for the late-maturing broccoli variety. The results showed that the different optimal combinations of applying N, P, and K fertilizers could be recommended, according to the different genotypes and soil nutrient levels.
