Biochar, widely employed as a soil amendment, has been reported to influence N dynamics through its redox-active moieties, but the effects on Feammox of biochar produced with different pyrolysis temperatures remain poorly understood. We conducted a slurry incubation in rice-paddy soil with ¹⁵N-isotope tracing to examine the impact of biochar pyrolyzed at 300 °C and 600 °C on Feammox under different Fe availability conditions (addition of ferrihydrite, goethite, or no Fe). Biochar pyrolysis temperature and Fe availability impacted rates of Feammox. Specifically, adding biochar pyrolyzed at 600 °C to soil at a 2 % mass ratio stimulated N loss through Feammox by 0.03 to 0.07 μg N g⁻¹ soil d^-1, likely by facilitating electron transfer via its surface redox-active moieties. Feammox was highly correlated with Fe reduction despite contributing only a small fraction to overall Fe reduction. Feammox rates were greatest with ferrihydrite addition and lowest with no Fe addition, and correlated with the abundance of a known Feammox bacterium (<em>Acidimicrobiaceae</em> bacterium A6). In contrast, biochar pyrolyzed at 300 °C did not stimulate Feammox, likely due to a lack of electron shuttling capacity. Overall, our findings highlight a stimulation effect of biochar pyrolyzed at high temperature on promoting N loss as dinitrogen, underscoring its potential utility for environmentally-friendly removal of excess N from anoxic soil.</div></div>","PeriodicalId":12511,"journal":{"name":"Geoderma","volume":"459 ","pages":"Article 117372"},"PeriodicalIF":5.6,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144177723","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}

The Digital Soil Mapping (DSM) literature has identified two levers for better communicating uncertainty: uncertainty representations that allow users to integrate uncertainty better than with a separate raster map, and spatial aggregation, which consists of representing the spatial information at a coarser resolution to reduce its uncertainty. For the first time in DSM, we involved a large number of end-users (263 people) via a web-based survey to evaluate alternative cartographic representations of soil map uncertainty. Respondents were assigned a decision-making task and asked to select the map that offered the best support, choosing between two maps that displayed the same soil information but differed in how uncertainty was represented and/or in the level of spatial aggregation. The choices made by the respondents as well as the comments they left at the end of the study provided a large dataset from which we could identify factors driving their preferences. We demonstrate that end-users strongly prefer uncertainty to be shown on a separate map, and also favor moderately aggregated maps. Our results question the conventional representation of soil data using high-resolution and high-uncertainty maps. We hope that this work will be valuable to scientists in soil science, as well as in other environmental mapping communities, such as ecosystem services and biodiversity, and help them more effectively communicate uncertainty to their end-users.</div></div>","PeriodicalId":12511,"journal":{"name":"Geoderma","volume":"459 ","pages":"Article 117302"},"PeriodicalIF":5.6,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144166356","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}

In this study, we aimed at building a simple pedotransfer function to estimate OC_fine content measured using a size fractionation protocol in French soils. We define OC_fine as SOC content measured in the &lt; 50 µm fraction. We used information from the French Soil Quality Monitoring Network (RMQS, 706 observations) and from a literature search (245 observations) to build and validate the pedotransfer function. We used the Random Forest algorithm and partial dependence plots in an exploratory data analysis, to analyze the variables influencing OC_fine contents and to study the shape of their relationship with OC_fine. Using the knowledge gained from the exploratory analysis, we constructed a simple pedotransfer function. A slight inflection in the OC_fine content was detected with increasing SOC content and a good approximation of OC_fine content was reached using a second-degree polynomial relationship, with distinct coefficients depending on the land cover (i.e., croplands and permanent crops, grasslands, natural grasslands, and forests and shrubs). A cross-validation of the pedotransfer function led to an RMSE of 2.2 g kg⁻¹ and an independent validation led to an RMSE of 2.0 g kg⁻¹. The domain of applicability of the pedotransfer function was defined as being restricted to topsoil horizons and a SOC content ≤ 90 g kg⁻¹. The estimated OC_fine is deemed equivalent to a measure after a complete soil dispersion and a size fractionation protocol. The proposed pedotransfer function could be easily used in future soil carbon modeling frameworks. From a land management perspective, the shape of the relationship found between SOC and OC_fine encourages increasing SOC levels to store more carbon in soil, including in the OC_fine fraction.</div></div>","PeriodicalId":12511,"journal":{"name":"Geoderma","volume":"459 ","pages":"Article 117366"},"PeriodicalIF":5.6,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144166357","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}

In a full factorial glasshouse experiment using pots with 2.5 kg soil and adding N (0 and 100 kg N ha⁻¹), P (0 and 50 kg P ha⁻¹) fertilizer and lime (0, 3.5, 14 t ha⁻¹, 100 % calcium carbonate equivalent) we investigated the main and interactive effects of our treatments on <em>RE_N</em> and <em>RE_P</em> in wheat (<em>Triticum aestivum</em>) grown in a P-poor soil.

Likewise, N fertilization increased <em>RE_P</em> from 6 % to 8 % averaged across the liming treatment. However, liming decreased <em>RE_N</em> (only when P fertilizer was added), possibly because of enhanced net N mineralization in the soil making plants less dependent on N fertilizer with liming, and increased <em>RE_P</em>, possibly because of reduced fertilizer P-immobilization in the soil with low pH. Overall, N and P fertilizer and lime addition changed <em>RE_N</em> and <em>RE_P</em> by changing wheat growth along with N and P uptake, thereby affecting soil available nutrients, nitrous oxide emissions and N and P loss through leaching.

Results show that SOC_sp derived from the boundary line approach was about 2.1 times higher than those estimated by the quantile regression (QR) approach.

We analyzed SOC physical fractions and microbial activity under varying soil structural and chemical conditions, using the SOC vulnerability index (SOCVI), defined as the ratio of labile to stable fractions, to assess SOC stability. Results show that urban parks and tree-only roadside greenery have 87% lower SOC content than grasslands on average, and they contain a disproportionately high fraction of labile C, which increases SOC vulnerability. Tree-only roadside greenery exhibited particularly high SOCVI primarily because, despite low overall C inputs, its microbial activity relative to SOC is high, leading to inefficient stabilization of SOC as stable fractions. This condition is further exacerbated by alkaline pH and compaction, which hinder effective C sequestration. Although belt-type roadside greenery achieved higher SOC content through additional C inputs from understory vegetation and slightly improved soil structure, its SOCVI remained high, indicating that increased C inputs alone does not ensure stabilization. Structural equation modeling identified that mean annual temperature (MAT), soil pH and glomalin-related soil protein (GRSP) as key regulators of SOCVI.
