While numerous soil physiochemical variables have been identified as key influencers of comammox <em>Nitrospira</em> distribution, the role of soil texture in shaping these communities remains largely uncertain. Here, we explored the diversity, community structure of comammox <em>Nitrospira</em>, and their driving factors, including soil texture in 237 rice-wheat rotation soils. The results indicated that soil pH and texture were the primary factors influencing the Shannon diversity and richness of comammox <em>Nitrospira</em>. Comammox <em>Nitrospira</em> Shannon diversity and richness were positively associated with soil pH and silt content, but negatively correlated with clay content, suggesting that finer-textured soils harbored lower comammox <em>Nitrospira</em> diversity. Additionally, silt content emerged as the second most influential factor, after pH, shaping comammox <em>Nitrospira</em> community structure. Clade A.2 was found as the predominant comammox <em>Nitrospira</em> clade in rice-wheat rotation soils, representing 59.3 % of the total sequences. Clade A.2 exhibited a positive correlation with sand and clay contents but a negative association with silt content. Conversely, Clades A.3 and B demonstrated the opposite pattern. Overall, our study underscores the critical role of soil texture as a mediator of comammox <em>Nitrospira</em> diversity and community structure, emphasizing the need to consider soil texture in investigations of comammox <em>Nitrospira</em>.</p></div>","PeriodicalId":12057,"journal":{"name":"European Journal of Soil Biology","volume":"122 ","pages":"Article 103661"},"PeriodicalIF":3.7,"publicationDate":"2024-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141954204","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results showed that soil erosion significantly reduced the MBC content but increased the microbial entropy of sloping croplands in black soil region (BS) (22 %, 43.6 %), purple soil region (PS) (25.5 %, 26.2 %) and red soil region (RS) (28.9 %, 21.9 %), but not in loess soil region (LS).

In this study, we carried out potting experiments with biochar and wood vinegar as saline soil amendments under rice cultivation conditions with four different treatments: without biochar or wood vinegar (CK), biochar (BC), wood vinegar (WV), and biochar + wood vinegar (BC + WV). The results showed that the addition of biochar and/or wood vinegar decreased the soil pH and electrical conductivity (EC), which led to an increase in the gene abundance of ammonia-oxidizing bacteria (AOB), thereby benefiting the advancement of the potential nitrification rate (PNR). WV and BC + WV significantly increased the gene abundance of <em>Nitrospira</em>. In addition, the addition of biochar and wood vinegar altered the community composition of ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB), while the NH₄⁺-N content was the key factor affecting the nitrifier communities. Compared to the CK group, biochar and/or wood vinegar significantly increased the relative abundance of <em>Nitrosospira</em> cluster 3 b in AOB and unknown affiliation in nitrite-oxidizing bacteria (NOB). Overall, the abundance and community composition of AOB contributed more to the PNR than those of AOA, while NOB played a pivotal role in the potential nitrite oxidation (PNO) rate in sodic saline soils. In conclusion, the addition of biochar with wood vinegar had positive effect on improving sodic saline soils by improving the physicochemical properties of the soils, increasing the abundance of nitrifier and changing the community structure of nitrifier.

Mycorrhization is a unique type of inter-root engineering that improves nitrogen acquisition efficiency by plant roots. We selected potted mulberry trees inoculated, two dominant arbuscular mycorrhizal fungi (AMF) with <em>Funneliformis mosseae</em> (Fm) and <em>Rhizophagus intraradices</em> (Ri), to clarify the effects of AMF on the root nitrogen content of mulberry trees. Meanwhile, the key factors of soil nitrogen changes caused by AMF were analyzed, based on the primary role of soil nitrogen as the source of root nitrogen. Simultaneously, the potential of AMF to promote the acquisition of different forms of nitrogen by mulberry roots was investigated. Our findings indicate that the inoculation of mulberry plants with Fm and Ri, improved plant height and increased nitrogen accumulation in the roots and shoots. Additionally, AMF regulates nitrogen transformation, significantly increasing soil nitrate nitrogen (NO₃⁻-N) and dissolved organic nitrogen (DON) levels. The results indicated that soil NH₄⁺-N, NO₃⁻-N, and DON contributed to the observed changes in root nitrogen accumulation. The largest contribution (22.0 %) to the overall effect size was made by NO₃⁻-N. AMF stimulated soil microbial activity and significantly increased soil glomalin-related soil protein (GRSP), enzyme activity, and soil microbial biomass (SMB). Urease activity and microbial biomass carbon (MBC) both increased exponentially by 118.7 % and 115.2 %, respectively. Higher GRSP, enzyme activity, and SMB were positively correlated with changes in soil nitrogen patterns, and GRSP had the most significant effect on changes in the soil nitrogen dynamics. Our study confirmed that inoculation with AMF not only regulates soil nitrogen dynamics but also diversifies plant nitrogen sources. This is achieved by increasing plant growth and enhancing soil microbial activity. Ultimately, this enhances plant root nitrogen nutrition. Therefore, AMF promote root nitrogen accumulation and enhance root nitrogen uptake through GRSP-regulated soil nitrogen, providing a theoretical basis for the management of rocky desertification.</p></div>","PeriodicalId":12057,"journal":{"name":"European Journal of Soil Biology","volume":"122 ","pages":"Article 103659"},"PeriodicalIF":3.7,"publicationDate":"2024-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141932226","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aiming to contribute to the scarce information on earthworm ecology in the region, the objectives of this work were 1) to characterize the earthworm communities in agriculture and natural ecosystems, and 2) to assess the relationship between land use and richness of native and exotic earthworm species. Related to the latter objective, we hypothesized that the difference in the number of exotic and native species depended on the degree of disturbance, and predicted that exotic species would dominate in more disturbed soils. We sampled organic and nonorganic agricultural fields including wheat in the rotations in the South and the North-West of Uruguay. Undisturbed sites, <em>i.e.</em> with no recent agriculture activity, close to each sampling plot served as controls. Analyses were conducted to elucidate whether other variables, besides disturbance and location, could be influencing earthworm community structure and composition. In both locations, exotic species dominated in control plots, i.e. less or non-disturbed land, and were associated to higher N, C and soil porosity. Moreover, in the North-West, natives would dominate in terms of richness in most agriculture plots. The mean body weight was larger in the South, where there were more exotic species, than in the North-West, where there were more native species.

We sampled earthworm communities from four different habitat types along a disturbance gradient: agricultural crop land, forest around crop fields (buffers), recently restored natural grassland, and forests from conservation areas. As most species living in Canada are considered exotic and because of the recent colonization of Canadian soils by mostly European species after the extinction of the native species due to the glaciation of North America during the Pleistocene, we hypothesized that the impact of agricultural practices will be similar to what is observed in Europe: for example, crop habitat showing lowest abundance, richness, and proportion of epigeic and anecic species, due to lesser soil organic matter content and higher soil disturbance. We also hypothesized that important soil variables would be associated with these habitat differences. For each habitat we sampled earthworms using a combination of two methods (quantitative + qualitative) at three replicate sites, for two years between May and July together with important environmental variables. We found lower density and diversity of earthworms in crop habitat and proportionally more epigeic species than expected. Contrary to our predictions, forest-buffer earthworm communities were more similar to crop than to forest habitats, and soil environmental variables could not explain the variations in the spatial distribution of earthworm communities. In fact, our results revealed a more homogeneous distribution of the species diversity across the habitat gradient at local scales in Southern Ontario. This was mainly associated with spatial factors, probably due to historical extinction-colonization events of earthworms in Canada and the high invasive potential of the species currently present.</p></div>","PeriodicalId":12057,"journal":{"name":"European Journal of Soil Biology","volume":"122 ","pages":"Article 103655"},"PeriodicalIF":3.7,"publicationDate":"2024-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141932141","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
