“…The RDA demonstrated that the abundance of Pseudomonas was in direct proportion with the NH 4 + -N in both the dry toilet samples and septic tank effluents, which was related to the fact that nitrogen was required for bacterial growth, with particularly high nutritional needs during the growth of Proteobacteria (Zoppini et al 2010 ). Liu et al ( 2016 ) also stated that increased NH 4 + -N deposition enriched Proteobacteria, which was consistent with our finding. This was attributed to NH 4 + -N being a direct utilization form for most bacteria, including Proteobacteria (Zhou et al 2018a , b ).…”

Recent studies on the microbial community composition of human excrement after rural household toilet treatment are unclear regarding the effects and risks of using recycled products as fertilizers in agriculture. In this study, we used Illumina high-throughput sequencing to investigate the microbial community structure of the excrement from 50 Chinese rural household toilets on a spatial scale, and we evaluated the impact of select geochemical factors on the bacterial and fungal communities in the human excrement. Multivariate analysis showed that there was a significant spatial differentiation of the human excrement in microbial communities after all toilet treatments. Twenty dry toilet samples and thirty septic tank samples had similar bacterial (Firmicutes, Proteobacteria, Actinobacteria, and Bacteroidetes) and fungal phyla (Ascomycota and Basidiomycota), differing only in the proportions of the microorganisms. For both dry toilet samples and septic tank samples, the pH and ammonium nitrogen were found to be the major driving forces affecting the changes in bacterial community structures ( p <0.05), while there was no correlation found for the fungal community with environmental factors in China ( p >0.05), except in the northern regions, where the total phosphorus was found to be significantly correlated with the fungal community ( p <0.05). Network analysis confirmed that NH 4 + -N had the most significant impact on the content of pathogens. Certain pathogens were still detected after toilet treatment, such as Streptococcus , Bacteroides , Aspergillus , and Chrysosporium , and the proportion of potential pathogenic bacteria in dry toilets was higher than that in septic tanks, suggesting that septic tanks were better than dry toilets in treating human excrement. These results provide an ecological perspective for understanding the large-scale geographic distribution of household excrement microbial communities in rural areas and for improving human excrement treatment technologies and avoiding the risks of agricultural applications.

“…The relationship between the NH 4 + -N concentration and the bacterial community composition was previously observed (Zeng et al 2016 ). The study of Liu et al ( 2016 ) also found that the relative abundance of the Acidobacteria phyla was sensitive to the soil NH 4 + -N concentration.…”

“…This implied that the dependence of fungal diversity on nitrogen deposition was related to a threshold value of nitrogen concentration, beyond which higher nitrogen concentration would suppress fungal diversity. This might be because nitrogen deposition would increase soil nutrients, facilitating fungal growth, but only at concentrations within a certain range, which is in agreement with Liu et al (2016). Exceeding the threshold concentration, high-level nitrogen would change the availability of soil nutrients, facilitate the growth of certain microbial species (e.g., those preferentially utilizing plant debris) while suppressing other microbial species, and thus make the microbial community diversity decrease.…”

In order to understand the effects of nitrogen deposition on soil fungal diversity, a study was conducted with a Deyeuxia augustifolia wetland in the Sanjiang Plain, China, using an experimental setup simulating nitrogen deposition at different loads over a five-year period. Three conditions were investigated: N1 (no artificial deposits, control), N2 with low-level nitrogen deposition (4 g N·hm -2 a -1) and N3 with high-level nitrogen deposition (8 g N·hm -2 a -1). At the end of the experiment the soil physiochemical characteristics were determined and high-throughput sequencing was employed to monitor the soil fungal diversity. The addition of exogenous nitrogen to the soils changed the physicochemical properties of the soils and affected the fungal community composition and the relative abundance of species: low doses increased the diversity while high doses reduced the fungal diversity. In each of the three types of nitrogen-amended soils, the most predominant phyla were Ascomycota followed by Basidiomycota. The abundance of Basidiomycota decreased with nitrogen deposition, while Ascomycota changed in the opposite direction. A heatmap tree based on ITS rDNA sequences illustrated how different fungal communities responded differently to nitrogen deposition. The findings in the present study provide fundamental data and theoretical insights that can be employed to predict the effects of atmospheric nitrogen deposition on wetland soil fungi and wetland ecosystems in Sanjiang Plain.

“…Moreover, investigating the effects of C. oleifera cultivation on soil resources could facilitate the sustainable development of the C. oleifera industry, particularly if the selected varieties have desirable economic characteristics and delay the associated decline in soil fertility. Changes in soil quality would affect the growth, reproduction, and activity of soil microorganisms, alter the structure and function of soil microbial communities, and influence the transformation of substances and the availability of nutrients in the soil (Bahnmann et al., 2018; Liu, Dong, Sun, & Jiao, 2016). Additionally, previous studies have reported that root exudates shape the rhizosphere microbial community structure.…”

Camellia oleifera Abel. is an important woody oil plant that could solve the disparity between the supply and demand of edible oil in China. Although numerous excellent clones have been developed and introduced to enhance production, the interactions between high yield clones and soil ecosystem sustainability remains poorly understood. The high‐yielding period of a C. oleifera plant is approximately 100 yr; therefore, appropriate clone selection is crucial. We evaluated the differences between four major clones based on soil nutrient and microbial community structure, following cultivation for 10 yr to infer the influence of clone selection on soil sustainable utilization. The results showed significant differences in soil nutrient status and rhizosphere microorganism populations among clones. The bacterial communities in the XL1 plots had the highest species richness. According to the results, clone XL1 was found to be suitable for sustainable cultivation considering the high organic matter concentration and microbial diversity in the soil where it was cultivated. Although clone XL210 exhibited high yields and good economic benefits, it had a risk of inadequate production capacity in later periods, meaning that fertilization rates would have to be increased, and some annual plants with rich rhizosphere flora would need to be integrated in the farms to enhance microbial diversity in the soil to decelerate soil fertility decline.
