“…At the class level, the main enriched OTU in the rhizospheric soil was Agaricomycetes after RF. Most Agaricomycetes species are saprotrophic species and play key roles in the decomposition of organic matter, such as wood and plant litter (Hibbett, 2007; Wang J. et al, 2018; Wang M.M. et al, 2018), which might explain the high relative abundance of Agaricomycetes in RF.…”

Rice-frog cultivation is a traditional farming system in China and has been reintroduced as an agricultural practice in China in recent years. The microbial community in paddy rhizospheric soils has attracted much attention because many microorganisms participate in functional processes in soils. In this study, Illumina MiSeq sequencing-based techniques were used to investigate soil microbial communities and functional gene patterns across samples obtained by conventional rice cultivation (CR) and rice-frog cultivation (RF). The results showed that RF significantly affected the microbial community composition and richness, which indicated that the rhizospheric microorganisms responded to the introduction of tiger frogs into the paddy fields. Operational taxonomic units (OTUs) from Sandaracinaceae , Anaerolineaceae , Candidatus Nitrososphaera, Candidatus Nitrosotalea, Candidatus Nitrosoarchaeum and some unclassified OTUs from Euryarchaeota and Agaricomycetes were significantly enriched by RF. The abiotic parameters soil organic carbon (SOC), nitrate nitrogen (NO 3 − -N), and available phosphorus (AP) changed under RF treatment and played essential roles in establishing the soil bacterial, archaeal, and fungal compositions. Correlations between environmental factors and microbial communities were described using network analysis. SOC was strongly correlated with Anaerolineaceae , Methanosaeta , and Scutellinia . NO 3 − -N showed strong positive correlations with Opitutus , Geobacter , and Methanosaeta. NH 4 + -N was strongly positively associated with Sideroxydans , and TN was strongly positively correlated with Candidatus Nitrotoga. Compared to conventional CR, RF greatly enriched specific microbial taxa. These taxa may be involved in the decomposition of complex organic matter and the transformation of soil nutrients, thus promoting plant growth by improving nutrient cycling. The unique patterns of microbial taxonomic and functional composition in soil profiles suggested functional redundancy in these paddy soils. RF could significantly affect the bacterial, archaeal, and fungal communities though changing SOC and AP levels.

“…1a). This could have been caused by a shift in plant phenology, including plant-derived labile nutrients, litter, and root exudates (Wang et al 2018;Zubek et al 2016). Typically, plants produced new roots and stimulated an increased AMF mycelial network that extended into the soil for nutrient uptake during the growing season (Bohrer et al 2004;Johnson et al 2010).…”

Arbuscular mycorrhizal fungi abundance was sensitive to nitrogen addition but diversity was sensitive to phosphorus addition in karst ecosystems

Determining the effects of nitrogen (N) and phosphorus (P) application on arbuscular mycorrhizal fungi (AMF) communities is important for predicting AMF responses to nutrient deposition. The AMF parameters and soil properties were monitored in karst grassland after 2 years of N and P addition. Then, AMF abundance, diversity, and community composition significantly differed between seasons. AMF abundance was higher in July (summer) than in December (winter), whereas richness and Chao1 estimator values showed the opposite results. The numbers of the genera Funneliformis and Sclerocystis were significantly more abundant in December, but the proportions of Scutellospora, Redeckera, and Diversispora were significantly higher in July. N and NP treatments significantly increased AMF abundance; richness and Chao1 values in the P treatment were significantly higher than those of the control in July. AMF community composition changed substantially between December and July but did not respond to fertilization. AMF abundance was significantly correlated with total N (TN), while AMF richness was also significantly correlated with available P (AP) and pH. pH and nitrate N (NO 3 −-N) strongly affected AMF community composition. These results suggested that P became more limiting with N fertilization, AMF investment increased access to more P, and richness was lower when certain AMF taxa (Diversisporales) increased in abundance during the growing season and under more P-limiting conditions. These results also suggested that N and P addition have specifically different effects on AMF abundance and diversity, and consequently potential effect on long-term vegetation composition and productivity.

“…Additionally, at more local scales, plant species identity (Hannula, Ma, Pérez-Jaramillo, Pineda, & Bezemer, 2020) and agricultural practices (Bender, Wagg, & van der Heijden, 2016;Frąc et al, 2018;Oehl, Laczko, Oberholzer, Jansa, & Egli, 2017;Rillig et al, 2016) have been identified as important factors affecting fungi. More specifically, studies have shown that soil tillage (Schmidt, Mitchell, & Scow, 2019;Sharma-Poudyal, Schlatter, Yin, Hulbert, & Paulitz, 2017;Sommermann et al, 2018), fertilizer regime (Qin et al, 2015;Wang, Rhodes, Huang, & Shen, 2018;Zhu et al, 2016), cover crops (Benitez, Taheri, & Lehman, 2016;Detheridge et al, 2016), selection of crop species and rotation (Sommermann et al, 2018) and organic amendments (Lourenço, Suleiman, Pijl, Cantarella, & Kuramae, 2020;Qin et al, 2015) change the composition of soil fungal communities. However, it is likely that these effects are at least partially dependent on local conditions, including soil type, climatic conditions and soil abiotic factors (Tedersoo et al, 2014).…”

Cropping practices have a great potential to improve soil quality through changes in soil biota. Yet the effects of these soil-improving cropping systems on soil fungal communities are not well known. Here, we analysed soil fungal communities using standardized measurements in 12 long-term experiments and 20 agricultural treatments across Europe. We were interested in whether the same practices (i.e., tillage, fertilization, organic amendments and cover crops) applied across different sites have predictable and repeatable effects on soil fungal communities and guilds. The fungal communities were very variable across sites located in different soil types and climatic regions. The arbuscular mycorrhizal fungi (AMF) were the fungal guild with most unique species in individual sites, whereas plant pathogenic fungi were most shared between the sites. The fungal communities responded to the cropping practices differently in different sites and only fertilization showed a consistent effect on AMF and plant pathogenic fungi, whereas the responses to tillage, cover crops and organic amendments were site, soil and crop-species specific. We further show that the crop yield is negatively affected by cropping practices aimed at improving soil health. Yet, we show that these practices have the potential to change the fungal communities and that change in plant pathogenic fungi and
