The main objective of this contribution is to release an entire dataset of soil samples surveyed by the Secretary of Agriculture, Livestock, Rural Development, Fisheries, and Food (SAGARPA) in collaboration with the Food and Agriculture Organization of the United Nations (FAO) in the year 2012. The dataset consists of more than 4000 compound samples surveyed on managed cropland. SAGARPAS's main objective was to generate a new index to assess and monitor the current and future state of soil when sustainable soil practices take place. A complete set of physicochemical properties was determined via laboratory analysis for all records in the dataset, namely: pH, EC, OM, BD, Sand, Silt, Clay, Texture, P, N, K, Ca, Mg, Na, CEC, Sodium Adsorption Ratio (SAR), Exchangeable Sodium Percentage (ESP), and including the calculation of the Sustainable Soil Land Use Subindex (SSLUS). We presented a reviewed dataset with the potential to contribute to a large variety of studies, ranging from agricultural pinpointing of the best conditions for crop production to digital soil mapping and modeling and agronomical studies.

The aim of this study is to explore the pedogenesis of ASSs in a tropical climate and to assess the impact of ASS on surface water quality at the end of the seasonal re-flooding period. An integrated study of soil, water and sediment was carried out in an area in the Doce River Delta, Espírito Santo state, Brazil. The results indicate that seasonal re-flooding restores reduction processes of inorganic species in soils, but with low proton consumption. Re-flooding results in the preservation of chemical characteristics resulting from sulfurization, as verified mainly in pH values lower than 4.0, characterising ASSs with a thionic horizon. The maintenance of acidic conditions is strongly influenced by the complexation of exchangeable acidity, as well as the acidity retained in Fe hydroxysulfates, both generated in the sulfurization process. As a result, the activity of sulfate-reducing microorganisms is limited, restricting proton consumption through reductive dissolution of minerals containing Fe<sup>3+</sup>, supplying iron and other potentially toxic elements to the acidic soil solution. Drainage and impact of these soils are shown by the deterioration of the surrounding surface water quality at the end of the wet period, with high concentrations of acidity, sulfate and potentially toxic elements. The acidic and reduced conditions accentuate iron exports that precipitate onto bottom sediments, which is an important scavenger of potentially toxic elements. This in situ study concludes that the remediation efficiency of ASSs exposed to oxidising conditions through seasonal re-flooding is dependent on the degree of sulfurization of soil, and that aggravating effects of re-flooding can be observed in the surrounding surface water.</p>","PeriodicalId":12043,"journal":{"name":"European Journal of Soil Science","volume":"76 3","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ejss.70115","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143892938","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Decision support tools (DSTs) have emerged as essential tools to help make accurate, evidence-based agricultural decisions aimed at enhancing productivity, profitability, and effective soil health management. Nevertheless, the adoption of these tools remains limited among farmers and varies across different regions. The aim of this study was to investigate, through a participatory approach, the challenges and drivers influencing the uptake and adoption of DSTs for sustainable soil management in Europe and Turkey. Our goal was to engage various stakeholders to identify the challenges and drivers associated with this process and collaboratively develop actionable recommendations to expand the application of DSTs. Multi-stakeholder workshops were conducted in Italy, Latvia, Sweden and Turkey, bringing together end-users, farmers, advisors, tool developers, researchers and policymakers from diverse agricultural contexts. The discussions during these workshops addressed the current use of DSTs, barriers to adoption, and potential solutions for scaling their use. The findings revealed that the primary barriers to adoption and scaling included costs, tool viability, data complexity, limited access to technical support, compatibility issues and insufficient marketing. To overcome these barriers and enhance the appeal of DSTs to users, stakeholders highlighted the necessity for user-friendly, affordable tools that offer enhanced transparency, real-time information, and adaptability to local farming conditions. Furthermore, stakeholders emphasised the importance of user-driven designs that could stimulate the innovation process and consider the interactions between human and technology. This study emphasises the complexity of adopting and scaling DSTs and the need for considering the local agricultural context. Stakeholder insights were categorised into a set of recommendations such as defining the scope of DSTs application, enhancing capacity building, creating a road map for stakeholders, and considering regional disparities in the participatory implementation process.

The area, influenced by sulfidization and sulfurization processes, shows significant variations in the concentration of these elements due to interactions between chemical element characteristics, soil properties, and landscape features.

The discrepancy between indices highlights the critical importance of selecting an appropriate background for a realistic assessment of contamination by potentially toxic elements in estuarine soils.

The spatial distribution of layer classes exhibited depth-dependent variation, although it was less pronounced than the east-to-west variation across Australia.

Ammonium addition can alleviate nitrogen deficiency for methanotrophs, but ammonium can also inhibit their growth when present in excess. However, the threshold concentration for this switch is not currently known. Here we report the results of a nine-day laboratory incubation experiment that sought to examine the effects of increasing ammonium concentrations on methane oxidation in rice paddy soil at refined concentration intervals.

The article discusses future directions for AI in soil science, such as developing new mathematical soil matrices and integrating AI with soil science knowledge to improve the precision and efficiency of soil assessments. As AI evolves, its potential in soil science includes generating new hypotheses, optimising soil carbon–mineral associations for better sequestration and enhancing soil phenotyping with high-throughput data analysis. Integrating AI with physical models could lead to more precise, data-driven soil management practices that support net-zero, nature-positive stewardship for improved soil security.</p>\u0000 </div>","PeriodicalId":12043,"journal":{"name":"European Journal of Soil Science","volume":"76 2","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143831112","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}
