However, the degree to which CH<ce:inf loc=\"post\">4</ce:inf> emission and its environmental controls change with such anthropogenic disturbances has been rarely assessed with direct empirical evidence. To quantify these disturbance effects, we utilized the eddy covariance (EC) approach to continuously measure net CH<ce:inf loc=\"post\">4</ce:inf> exchange from Jul. 2022 to Oct. 2023, covering both pre- and post-removal periods, in a disturbed coastal wetland of Southeast China experiencing an intensive cordgrass removal in late Oct. 2022. Our analyses, based on this unique EC dataset of high-frequency (30-min) time series CH<ce:inf loc=\"post\">4</ce:inf> fluxes, revealed that (a) the removal caused a pulse of CH<ce:inf loc=\"post\">4</ce:inf> emission peaking one month later up to 0.76 g CH<ce:inf loc=\"post\">4</ce:inf> m<ce:sup loc=\"post\">−2</ce:sup> d<ce:sup loc=\"post\">-1</ce:sup>, with the mean post-removal emission over ten times that of the pre-removal level (0.03 g CH<ce:inf loc=\"post\">4</ce:inf> m<ce:sup loc=\"post\">−2</ce:sup> d<ce:sup loc=\"post\">-1</ce:sup>); (b) the removal intensified the controls of tidal inundation and pumping on CH<ce:inf loc=\"post\">4</ce:inf> fluxes, showing much stronger pumping effects within two months following the disturbances; (c) the removal also enlarged the temperature sensitivity of CH<ce:inf loc=\"post\">4</ce:inf> emission, leading to larger daytime emission especially at afternoon hours; (d) the combination of enhanced tidal impacts and temperature dependence thus promoted the diel variability of CH<ce:inf loc=\"post\">4</ce:inf> fluxes during the post-removal period. These results suggest that coastal restoration via intensive cordgrass removals boosts both the magnitude and the diel variability of CH<ce:inf loc=\"post\">4</ce:inf> emission, highlighting the necessity of better understanding the climate impact of restoration activities. Future longer flux data with extended years are needed to further assess potential regime shift in soil CH<ce:inf loc=\"post\">4</ce:inf> biogeochemistry and long-term evolution of such unintended environmental costs of the restoration.","PeriodicalId":12511,"journal":{"name":"Geoderma","volume":"1 1","pages":""},"PeriodicalIF":6.1,"publicationDate":"2026-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146146752","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study explored the availability and transformation of P affected by APP1 (P species of P<ce:inf loc=\"post\">1</ce:inf>-P<ce:inf loc=\"post\">2</ce:inf>) and APP2 (P species of P<ce:inf loc=\"post\">1</ce:inf>-P<ce:inf loc=\"post\">7</ce:inf>) in two different soils, in comparison with conventional ammonium phosphates (APs). APP application increased Olsen-P by 10.7–24.8% in calcareous soil, but decreased it by 2.6–10.8% in acid soil relative to APs. In calcareous soil, APP significantly increased soluble-P, adsorbed-P, and Fe-associated P, as reflected by CaCl<ce:inf loc=\"post\">2</ce:inf>, NaHCO<ce:inf loc=\"post\">3</ce:inf>, and NaOH extractable Ps, while decreased more stable Ca-associated P and occluded P indicated by NH<ce:inf loc=\"post\">4</ce:inf>Ac and Na<ce:inf loc=\"post\">3</ce:inf>C<ce:inf loc=\"post\">6</ce:inf>H<ce:inf loc=\"post\">5</ce:inf>O<ce:inf loc=\"post\">7</ce:inf>-Na<ce:inf loc=\"post\">2</ce:inf>S<ce:inf loc=\"post\">2</ce:inf>O<ce:inf loc=\"post\">4</ce:inf>-NaOH extractable Ps. The changes in the composition of CaCO<ce:inf loc=\"post\">3</ce:inf> and Fe/Al oxides together with/without the reduced organic carbon loss mainly contributed to the decrease in P sorption/precipitation and the increase in P desorption/dissolution. In acid soil, APP significantly increased microbial biomass P, leading to reduced labile inorganic P and elevated labile organic P. Meanwhile, APP increased both oxalate-extractable and complex Fe/Al oxides, which affected P adsorption–desorption to a certain extent. Compared to APP1, APP2 resulted in P existing in a more labile adsorbed state, thereby increasing P availability in both calcareous and acid soils. The main processes affecting P availability in the calcareous soils were abiotic transformations, while biotic transformations played the key role in the acid soils.","PeriodicalId":12511,"journal":{"name":"Geoderma","volume":"6 1","pages":""},"PeriodicalIF":6.1,"publicationDate":"2026-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146146753","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pasture soils are vulnerable to compaction from animal treading, restricting gas diffusion and enhancing N₂O emissions. Although subsoiling alleviates compaction, its impact on soil O₂ status and N₂O emissions, particularly under high urine N load, remain poorly understood and rarely investigated. This in-situ field study (March-August 2023) evaluated the effect of subsoiling on soil moisture, O₂ content, relative gas diffusivity (D_p/D_o), functional gene abundance, N₂O emissions, and pasture production. Treatments included non-subsoiling or subsoiling, each with or without synthetic ruminant urine (713 kg N ha⁻¹). Subsoiling improved macroporosity, enhanced O₂ availability, increased D_p/D_o at 5, 10 and 20 cm depth (<em>P &lt; 0.001</em>), and reduced moisture at 10 cm depth (<em>P &lt; 0.001</em>). Subsoiling significantly reduced N₂O emissions by 52% and 81% of non-subsoiled plots for non-urine and urine treatments, respectively (<em>P &lt; 0.05</em>). D_p/D_o was strongly correlated with N₂O fluxes during the first 15 days following urine application (<em>R² = 0.59</em>–<em>0.87</em>), suggesting its utility as a predictive indicator under high substrate availability. Molecular analysis showed reduced <em>nirK</em> gene abundance under subsoiling, with limited response for other denitrification genes. Subsoiling had no significant effect on pasture yield or N uptake. Overall, subsoiling mitigates N₂O emissions by improving soil aeration and D_p/D_o while maintaining productivity, offering a promising strategy for sustainable N management in grazed pasture soils.</div></div>","PeriodicalId":12511,"journal":{"name":"Geoderma","volume":"467 ","pages":"Article 117716"},"PeriodicalIF":6.6,"publicationDate":"2026-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146134156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on this assumption, we developed a synergistic sample transfer strategy that integrates spectral similarity with environmental similarity under the Third Law of Geography, aiming to systematically screen the most comparable samples from the global soil spectral library to enhance the performance and robustness of local SOC modeling. A spectral-environmental similarity framework was established to identify samples that are simultaneously similar to the target region in spectral properties and environmental settings, and instance-based transfer modeling experiments were conducted in five representative small-sample regions (A-E). Results show that the synergistic strategy significantly improved modeling performance in most regions, with maximum increases in predictive power (as indicated by R²) of up to 18% compared with the baseline global transfer model. Remarkably, even when the number of global samples was reduced from 20,961 to around 200, the proposed strategy still outperformed local modeling and conventional global modeling approaches. In relatively stable environments, higher weights on environmental similarity yielded the best models, whereas in highly heterogeneous regions, spectral similarity played a more dominant role. The synergistic strategy also optimized the distribution of important spectral bands, enhanced SOC-responsive features in the visible region (450–750 nm), suppressed redundant information, and improved modeling efficiency. This study demonstrates that the proposed spectral-environmental synergistic sample transfer modeling method not only challenges the conventional assumption that “more samples guarantee better models” but also provides a novel pathway and theoretical support for the efficient use of global soil spectral libraries in regional SOC modeling.</div></div>","PeriodicalId":12511,"journal":{"name":"Geoderma","volume":"467 ","pages":"Article 117710"},"PeriodicalIF":6.6,"publicationDate":"2026-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146134155","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
