Arbuscular mycorrhizal fungi (AMF) play a crucial role in regulating soil structure and hydrological processes, yet their responses to contrasting REE mining practices and their contribution to runoff regulation remain poorly constrained. In this study, we examined the responses of AMF community to heap leaching (HL), in situ leaching (IL), and ecological restoration (ER) in REE mining areas, and further quantified the effects of indigenous AMF communities on runoff generation under simulated rainfall. Heap leaching resulted in severe soil desertification, whereas in situ leaching primarily induced soil acidification that is assessed based on soil pH. Relative to original ores (OR), HL significantly reduced AMF abundance and diversity and caused pronounced shifts in community composition. Ecological restoration partially recovered AMF abundance, Chao 1 and observed species, but did not restore them to reference levels, while IL also induced marked alterations in AMF community structure. Variations in AMF communities across mining sites were mainly explained by soil clay content, nutrient availability, and precipitation. Rainfall simulation experiments suggest that inoculation with indigenous AMF communities significantly reduced runoff from degraded tailing sands partially by enhancing soil binding agents and promoting plant growth. These findings identify AMF as an important, yet often overlooked, biological regulator of runoff generation in REE mining landscapes, and suggest that re-establishing native AMF communities represents a viable nature-based strategy for mitigating erosion and improving the hydrological functioning of disturbed soils.</div></div>","PeriodicalId":12057,"journal":{"name":"European Journal of Soil Biology","volume":"129 ","pages":"Article 103836"},"PeriodicalIF":3.3,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148183921","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}

To address this gap, an 11-year field experiment was conducted in a subtropical <em>Abies georgei</em> var. <em>Smithii</em> forest to evaluate the effects of ammonium-nitrate additions at four levels (0, 5, 15, and 30 kg N ha⁻¹ yr⁻¹) on microbial-mediated soil carbon sequestration. Certain characteristics were measured, including plant-derived carbon inputs (litter and root biomass), the structure and function of microbial communities, carbon dioxide emissions, and multiple soil organic carbon fractions. The highest nitrogen addition (30 kg N ha⁻¹ yr⁻¹) increased the soil active carbon by 35% and chronic organic carbon by 91%, whereas the inert organic carbon remained largely unchanged. Correspondingly, soil carbon dioxide emissions decreased by 41%, accompanied by declines in bacterial abundance and in genes associated with the degradation of starch, hemicellulose, chitin, and aromatic compounds. Path analysis suggested that long-term nitrogen enrichment-induced soil acidification altered bacterial richness and carbon-degradation gene abundance, reduced soil carbon dioxide emissions, and ultimately enhanced active and chronic organic carbon storage. Plant-derived carbon inputs (litter and roots) had no appreciable influence on soil organic carbon. Thus, the increase in soil carbon storage under the highest nitrogen additions was primarily attributable to the slowed degradation of organic carbon rather than enhanced plant growth. These findings underscore the need for a mechanistic understanding of the distinct microbial controls on soil carbon turnover to accurately assess the stability and persistence of soil organic carbon in subtropical forests under prolonged nitrogen enrichment.</div></div>","PeriodicalId":12057,"journal":{"name":"European Journal of Soil Biology","volume":"129 ","pages":"Article 103837"},"PeriodicalIF":3.3,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148183922","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}

Previous research has assessed the potential mass of surface applied organic matter that can be assimilated by earthworms; however, particle size of material may limit the rate of bioturbation and influence earthworm function and behaviour. The aims of the present study were to investigate the preference and utilisation of wheat (<em>Triticum aestivum</em>) straw residues at different particle sizes by two common, temperate earthworm species, <em>Lumbricus terrestris</em> and <em>Aporrectodea caliginosa.</em> These were addressed within controlled laboratory experiments, where two different scales were tested: Expt 1; with 3 modal straw lengths, as determined from the field post-harvest (40, 20 and 1 cm); and Expt 2; micro particle sizes (1 cm and 1 mm). The effect of straw length on earthworm utilisation was tested by earthworm incubation experiments in plastic bags, where removal from the soil surface was measured over a period of 8 weeks in monocultures and mixed species treatments. Litter removal was investigated by mass depletion over time and depth of incorporation. Choice chambers were used to quantify straw selection and removal at micro particle size. Expt 1 showed straw removal (63 ± 6 %) was significantly higher with a <em>L. terrestris</em> monoculture and 1 cm length. The largest masses of straw were incorporated at 0–60 mm depth of soil. There was no evidence to support a facilitation effect of <em>L. terrestris</em> on <em>A. caliginosa</em>, and increased earthworm mortality was detected in mixed species treatments. The choice chambers of Expt 2 indicated a preference for 1 mm particle size by both earthworm species with a more rapid use by <em>L. terrestris</em> than <em>A. caliginosa</em>.

The impact of bio-organic fertilization on soil nutrient cycling, carbon emissions, and carbon-cycling microbial communities was analyzed. The highest multi-nutrient cycling index was observed in COF treatment. Compared to the CF treatment, the bio-organic fertilization treatments (OF, 35.9 %; COF, 12.1 %) significantly (<em>P&lt;</em>0.05) reduced soil CO₂ emissions. Bacterial diversity (Chao1 index and Shannon index) in the OF and COF treatments was significantly (<em>P&lt;</em>0.05) higher than in the CF treatment, whereas fungal diversity (Shannon index) showed the opposite trend. Bacterial diversity played a crucial role in regulating soil nutrient status, as bacterial co-occurrence network exhibited a highly significant positive correlation with the multinutrient cycling index. Bio-organic fertilizer enhanced the activity of genes related to multiple systems (<em>pccA</em>), rTCA cycle (<em>icd</em>), reductive acetyl-CoA pathway (<em>cooC</em>), and Calvin cycle (<em>cbbL/R</em>), thereby promoting the conversion of CO₂ into stable organic compounds. Furthermore, structural equation modeling confirmed that soil carbon fixation genes, bacterial diversity, and network stability were key factors influencing CO₂ emissions.
