“…At the phylum level, soil AOB community composition was significantly affected by irrigation methods, while soil AOA community changes were less affected. This may be due to the fact that the ecological niche of soil AOA is smaller than that of AOB, that is, it occupies a narrower range of resources and space in the soil, while soil AOB has a wider ecological niche and can survive under different conditions such as temperature, pH and N elements ( Guo et al, 2023 ). Compared with FP, DI, and MF significantly changed the community structure and abundance of AOM in soil.…”

Ammonia oxidation is the rate-limiting step in nitrification and the key step in the nitrogen (N) cycle. Most soil nutrients and biological indicators are extremely sensitive to irrigation systems, from the perspective of improving soil fertility and soil ecological environment, the evaluation of different irrigation systems and suitability of selection, promote crop production and soil quality, study the influence of the soil microenvironment contribute to accurate evaluation of irrigation farmland soil health. Based on the amoA gene, the abundance and community diversity of ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB) and their responses to soil physicochemical factors and enzyme activities were studied in semi-arid areas of Northeast China. The study consisted of three irrigation systems: flood irrigation (FP), shallow buried drip irrigation (DI), and mulched drip irrigation (MF). The results showed that DI and MF significantly increased the contents of alkaline hydrolyzed nitrogen (AN), nitrate nitrogen (NO3–-N), soil moisture, and the activities of ammonia monooxygenase (AMO) and hydroxylamine oxidase (HAO). Compared with FP, DI significantly increased the abundance of soil AOA and AOB, while MF significantly increased the abundance of soil AOB. Irrigation systems significantly affected the community composition of ammonia-oxidizing microorganisms (AOM). Also, AN and soil moisture had the greatest influence on the community composition of AOA and AOB, respectively. The AOB community had better stability and stress resistance. Moreover, the symbiotic network of AOB in the three irrigation systems was more complex than that of AOA. Compared with FP, the AOA community under treatment DI had higher complexity and stability, maintaining the versatility and sustainability of the ecosystem, while the AOB community under treatment MF had higher transfer efficiency in terms of matter and energy. In conclusion, DI and MF were more conducive to the propagation of soil AOM in the semi-arid area of Northeast China, which can provide a scientific basis for rational irrigation and N regulation from the perspective of microbiology.

“…Moreover, the study demonstrated that SWI significantly impacted the abundance of soil nitrification genes ( amoC ), showing a pattern of initially decreasing and then increasing abundance with the increase in irrigation salinity. However, Guo et al (2023) suggested that soil salinity decreased the abundance of the nitrifying gene amoC . The difference may be related to the diverse soil properties.…”

“…A similar phenomenon emerges in N cycle analysis ( Tang et al, 2012 ; Cui et al, 2016 ). It was found that elevated soil salinity markedly suppresses the prevalence of denitrification and nitrification genes ( Li et al, 2012 ; Wang et al, 2018 ), while some studies showed SWI could increase the abundance of denitrification genes ( Guo et al, 2023 ). The soil microbial genes involved in C and N cycles are abundant, and their response to salt is intricate.…”

“… Yang et al (2023) indicated that soil salinity significantly reduced soil C cycling-related microbial diversity. Guo et al (2023) suggested that SWI significantly reduced the abundances of Proteobacteria and Acidobacteria , while simultaneously boosting the abundances of Gemmatimonadetes , Actinobacteria , and Chloroflexi. Previous findings suggested that the varied responses of distinct soil C and N cycle microbial taxa to salt stress ( Zhang et al, 2023 ).…”

Saline water irrigation (SWI) plays an important role in alleviating water resource shortages. At the same time, the salt input of irrigation water affects soil microorganisms which participate in various ecological processes of terrestrial ecosystems. However, the responses of soil microbial functional potential to long-term SWI remains unclear. Therefore, Metagenomics method was utilized in cotton fields under long-term SWI to reveal the microbial functional profiles associated with soil carbon and nitrogen cycles. Results indicated that SWI impacted the microbial functional profiles of soil carbon and nitrogen cycles in the cotton fields significantly. Especially, irrigation water salinity inhibited the relative abundances of sacC and vanB, which are soil carbon degradation genes. SWI also affected the functional gene abundance of nitrogen degradation, dissimilatory nitrate reduction, and nitrification. Moreover, SWI significantly increased the abundance of Candidatus_Cloacimonetes in both carbon and nitrogen cycles. In the discussion, we used person analysis found that soil salinity, pH, and ammonium nitrogen were important factors affecting the abundance of functional genes and microbial taxa. Overall, this study indicated that long-term SWI significantly influenced specific microbial functional genes and taxa abundance, which may lead to predictable outcomes for soil carbon and nitrogen cycling, and is of great importance in exploring the impact of SWI on soil environments.

Soil physical and chemical properties are important indicators to measure soil quality, and soil microorganisms can sensitively reflect changes in the soil environment. The impact of raising chickens under the forest on the soil environment under the forest can be fed back through the changes in both. However, previous studies on the effects of chicken breeding in Masson pine forests on soil physical and chemical properties and the diversity of soil microbial communities are rare. Thus, the design of this study was centered on the chicken coop, within 50 m, and every 10 m is a sample point. A five-point sampling method was used to study the impact of chicken flock activities on soil physical and chemical properties and microbial communities at different distances. The results showed that soil pH and nutrient content presented a decreasing trend with increasing distance, with significant differences among groups. Soil bulk density, water content and organic carbon content had opposite trends. The diversity of the soil microbial community showed a decreasing trend with increasing distance, in which bacterial diversity was higher than fungal diversity; Proteobacteria, Acidobacteria and Actinobacteria were the dominant bacteria; and Arthropoda and Ascomycota were the dominant phyla. This study shows that raising chickens under the forest has improved the forest environment, and a certain frequency of chicken activity or breeding density may be the key factor affecting the forest environment. When applying and promoting raising chickens under the forest, we should pay attention to the appropriate breeding density.
