To explore the microbial mechanisms driving the dynamic decoupling between SOC accumulation and stability, we conducted a 98-day decomposition experiment using acidic red soil and high C:N ratio Italian ryegrass crop residues. Crop residue decomposition significantly increased SOC contents by 14.76–41.33%. The contents of SOC, microbial biomass carbon, and easily oxidized organic carbon, as well as the related enzyme activities, initially increased before decreasing as decomposition progressed, peaking around 28 or 42 days. Concurrently, SOC chemical stability initially decreased, then stabilized, as indicated by the dynamics of the Alkyl C/O-alkyl C ratio and hydrophobicity. The early-stage SOC accumulation was closely associated with the rapid proliferation of specific r-strategy taxa and the increased relative abundances of glycoside hydrolase genes. Subsequently, the recovery of SOC stability coincides with a shift toward K-strategy microorganisms and increased relative abundances of auxiliary active genes. This highlights a microbial-mediated dynamic decoupling between SOC content and stability, driven by the succession of microbial CAZymes gene profiles. The shift in microbial life-history strategies (from r-strategy microorganisms to K-strategy microorganisms) and their associated enzymatic machinery could collectively facilitate the efficient utilization of root-derived carbon. Our findings reveal the microbial-mediated dynamic decoupling between SOC accumulation and stability during crop residue decomposition, which advances our understanding of how residue inputs contribute to soil carbon sequestration.</div></div>","PeriodicalId":34479,"journal":{"name":"Resources Environment and Sustainability","volume":"26 ","pages":"Article 100361"},"PeriodicalIF":9.2,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148539659","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study first analyzed the spatiotemporal patterns of cropland reclamation and ecological loss in China from 1990 to 2024, then employed the XGBoost-SHAP model to identify their underlying drivers. It also used the MaxEnt model to assess cropland suitability and the substitution potential of cropland restoration for reclamation, and quantified effects on grain production and ecosystem services via GAEZ-PCA-RF and InVEST models. Results showed cropland reclamation and ecological loss accounted for 26.25% and 22.46% of the base-period cropland area, respectively, with net reclamation concentrated in Northwest and Northeast China, and the two processes had opposing drivers. Ecologically lost cropland had 1.14 times higher suitability than reclaimed cropland, with the former's suitability rising and the latter's falling. Notably, 50.12% (25.95 Mha) of planned new reclamation could be substituted by cropland restoration, mainly in the Middle and Lower reaches of the Yangtze River drainage basin and South China (90.11%). This substitution would boost national grain production by 3.07% (23.26 Mt, 74.87% from Southern China) and raise the integrated ecosystem service index by 0.65%.

Specifically, it is unclear how DOC quality links bottom-up resource supply with top-down predatory control to regulate MNC accumulation. Here, we leveraged a natural temperature gradient across Mollisol regions of Northeast China to generate a diverse range of DOC profiles and microbial communities. We found that increasing mean annual temperature (MAT) significantly reduced DOC, soil organic carbon (SOC), and both bacterial and fungal necromass carbon (BNC and FNC). The BNC and FNC contents increased with DOC, particularly with humic- and protein-like fractions. The qPCR analysis revealed that the abundances of lower-trophic groups (bacteria and fungi) were positively correlated with these DOC components, while higher-trophic groups (protists and nematodes) showed a negative correlation. These shifts simplified and destabilized micro-food webs by increasing intra-trophic associations and decreasing cross-trophic associations, ultimately contributing to BNC and FNC accumulation. Collectively, this study proposes a conceptual framework where higher DOC content, particularly humic- and protein-like fractions, stimulates lower-trophic growth, reduces cross-trophic interactions, and enhances MNC formation. By integrating resource heterogeneity with multi-trophic associations, this study provides a mechanistic explanation for how soil food webs regulate carbon stabilization, suggesting that strategic management of DOC quality and trophic network structure can enhance soil carbon sequestration under sustainable management.</div></div>","PeriodicalId":34479,"journal":{"name":"Resources Environment and Sustainability","volume":"26 ","pages":"Article 100360"},"PeriodicalIF":9.2,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148539738","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our previous work confirmed that the plant-growth-promoting rhizobacterium <em>Bacillus velezensis</em> HR6-1 alleviates salt stress in substrate-cultivated tomatoes, whereas the underlying regulatory mechanism of HR6-1 in soil-cultivated systems remains unclear, limiting its practical application in saline soil. Here, multi-omics approaches were used to unravel the regulatory mechanism of HR6-1-mediated salt tolerance in soil-cultivated tomatoes. Physiochemically, HR6-1 could ameliorate the properties of saline rhizosphere soil by reducing soil pH and electrical conductivity, conserving available nutrients and improving soil enzyme activities, thereby alleviating salt stress at the root interface. Meanwhile, HR6-1 improved root physiological performance under salt stress by boosting antioxidant capacity, mitigating membrane damage, maintaining Na⁺/K⁺ homeostasis, and increasing the accumulation of nitrogen, phosphorus, lignin and melatonin. Transcriptomic and metabolomic analyses further revealed that HR6-1 modulated several core salt-tolerance pathways, including lignin and melatonin biosynthesis, auxin/gibberellin signalling and antioxidant defense, accompanied by the upregulation of key genes for ion transport and stress response. Moreover, HR6-1 reshaped rhizosphere microbial community by modulating tomato root exudates (adenine, sucrose, and amino acids) to recruit beneficial microbial taxa such as <em>Pseudomonas</em> and <em>Nocardiopsis</em>) under salt stress. Genomic, transcriptomic and in vitro functional assays further validated the growth-promoting and salt-adaptive capacities of HR6-1 under high-salt stress. This study systematically clarifies the multi-level regulatory mechanisms of HR6-1 in enhancing tomato salt tolerance and provides a promising biological strategy for sustainable tomato cultivation in saline soil, with further field validation required.</div></div>","PeriodicalId":34479,"journal":{"name":"Resources Environment and Sustainability","volume":"26 ","pages":"Article 100356"},"PeriodicalIF":9.2,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148539739","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
