“…Similar like fungal diversity in tea soils [38], Ascomycota, Basidiomycota and Zygomycota were the most dominant fungal phyla in different nitrogen addition soil samples, indicating the three phyla may play important roles in promoting nitrogen uptake that not depending on plant species. The abundance of Ascomycota and Basidiomycota were higher in N1 than N0 and N2, which was similar like Mueller et al (2012) study, Ascomycota and Basidiomycota were increased at intermediate levels of nitrogen addition, but declined at higher levels [39], indicating the abundance of Ascomycota and Basidiomycota may be influenced by nitrogen concentration.…”

Welsh onion (Allium fistulosum L.) constitutes an important plant species cultivated in China due the benefits and applications in different areas. Moreover, nitrogen is an essential nutrient during the growth and development of plant. Here, we present the effects of nitrogen on soil microbiome in welsh onion plants. We used High-throughput sequencing analysis to determine the diversity and abundances of microbes associated to soil rhizosphere in welsh onion under the influence of nitrogen application. Nitrogen application significantly influenced in the diversity of fungal community. The relative abundance of Orbiliomycetes increased with the nitrogen concentration. Nitrogen application did not affect the diversity of bacterial community, whereas the relative abundance of Acidobacteria_Gp2, Verrucomicrobiae and Sphingobacteriia decreased with the nitrogen condition. In this work, we introduced evidences of the effect of nitrogen fertilization on microbial community in welsh onion rhizosphere, and the change of microbial community may interfere the growth and development of welsh onion.

“…The increased fungal diversity at both sites may be ascribed to the following : i) the added N increased soil nutrient availability, modifying the range of ecological niches and favoring the survival, growth and reproduction of fungi [40]; ii) N addtion enhanced the plant net primary productivity of the tropical forest [41,42], leading to more plant-derived resources for soil fungal growth; iii) the rate of N addition (100 kg N ha -1 yr -1 ) likely caused an intermediate disturbance, and led to many vacant ecological niches that facilitate fungal colonization, according to the intermediate disturbance hypothesis [43]; iv) the adaptation of soil fungal diversity to acidic environments, as their internal pH regulatory mechanism to maintain a relatively neutral pH in their cells [44], and thus the acidic soil induced by N addition would result in acidophilic or acid-tolerant fungi in the studied forest. However, some previous studies found that soil fungal diversity was decreased or not significantly affected by N addition [45][46][47]. The discrepancies in these findings are not entirely surprising given that variations in the ecosystem types, background N deposition, soil layers, duration of treatment, and N addition rate [26,48,49].…”

Background: Soil fungi play critical roles in ecosystem processes and are sensitive to global changes. Elevated atmospheric nitrogen (N) deposition has been well documented to impact on fungal diversity and community composition, but how fungal community assembly respond to short- and long-term simulative N deposition remains poorly understood. Here, we carried out two field experiments to investigate the soil fungal community variations and assembly processes under short- (2 years) versus long-term (13 years) exogenous nitrogen addition (100 kg N ha-1 yr-1) in a N-rich tropical forest of China. Results: We observed that short-term N addition significantly increased fungal taxonomic and phylogenetic α-diversity, and shifted fungal community composition with significant increases in the relative abundance of Ascomycota and saprotrophic fungi, and decreases in the relative abundance of Basidiomycota and ectomycorrhizal (EcM) fungi. However, unremarkable effects were found under long-term N addition. The variations of fungal α-diversity, community composition, the relative abundance of major phyla, genera and functional guilds were mainly correlated with soil pH and the concentrations of NO3--N, and these correlations were much stronger under short- than long-term N addition. The results of null, neutral community models and the 39 normalized stochasticity ratio (NST) index consistently revealed that stochastic processes played predominant roles in the assembly of soil fungal community under N addition in the tropical forest, and that the relative contributions of stochastic processes were higher at short-term site. Furthermore, both short- and long-term N addition slightly loosened the co-occurrence networks of the fungal community. Conclusions: These findings highlighted that the responses of fungal community structure to N addition were duration-dependent, i.e., the fungal community was sensitive to the short-term N addition but become acclimatized to long-term N enrichment.

“…Nitrogen fertilizers are extensively used in tea plantations to improve the yield and increase the amino acid content of the tea leaves (Watanabe 1995 ). This increased nitrogen fertilization leads to alteration of soil chemical composition, pH decrease, reduction of soil fungal diversity, and change of the fungal composition in tea plantations (Yang et al 2019 ). Only a few studies have been conducted to understand the effect of different agriculture managements and fertilizer usage patterns on the microbial diversity in the tea plantations.…”

Background The soil quality and health of the tea plantations are dependent on agriculture management practices, and long-term chemical fertilizer use is implicated in soil decline. Hence, several sustainable practices are used to improve and maintain the soil quality. Here, in this study, changes in soil properties, enzymatic activity, and dysbiosis in bacterial community composition were compared using three agricultural management practices, namely conventional (CA), sustainable (SA), and transformational agriculture (TA) in the tea plantation during 2016 and 2017 period. Soil samples at two-months intervals were collected and analyzed. Results The results of the enzyme activities revealed that acid phosphatase, arylsulfatase, β-glucosidase, and urease activities differed considerably among the soils representing the three management practices. Combining the redundancy and multiple regression analysis, the change in the arylsulfatase activity was explained by soil pH as a significant predictor in the SA soils. The soil bacterial community was predominated by the phyla Proteobacteria, Acidobacteria, Actinobacteria, Chloroflexi, and Bacteroidetes in the soil throughout the sampling period. Higher Alpha diversity scores indicated increased bacterial abundance and diversity in the SA soils. A significant relationship between bacterial richness indices (SOBS, Chao and ACE) and soil pH, K and, P was observed in the SA soils. The diversity indices namely Shannon and Simpson also showed variations, suggesting the shift in the diversity of less abundant and more common species. Furthermore, the agricultural management practices, soil pH fluctuation, and the extractable elements had a greater influence on bacterial structure than that of temporal change. Conclusions Based on the cross-over analysis of the bacterial composition, enzymatic activity, and soil properties, the relationship between bacterial composition and biologically-driven ecological processes can be identified as indicators of sustainability for the tea plantation.
