As an academic discipline, soil science has been late in addressing gender equity, but several peer-reviewed studies have been published in the last 5 years. This study investigated gender equity in the soil science university faculty/academic staff (f/as) and soil professional societies in Canada, Egypt, Mexico, Nigeria, the United Kingdom and the United States of America (USA) using data publicly available on the Internet and anonymized data from soil science professional societies. We found that women still lagged behind men among our soil science f/as by considerable margins (69.2% men vs. 30.8% women for pooled data for all six countries in this study), and that the percentage of women in soil science f/as positions are similar to those for f/as women in many other scientific fields. There are differences in gender equity by soil science subdiscipline that vary by country. In countries where data are available to make comparisons, over the last 6–8 years, the gender gap has closed to some degree, both overall and for sub-disciplines. Women also often hold leadership positions in numbers that are lower than their representation among the f/as and membership in professional societies. In addition, women are recognised with awards such as society fellowship in numbers lower than their overall representation would suggest. This study concludes that progress has been made on several fronts in the last 6–8 years, but there is still much work to be done to achieve gender equity in soil science academia and professional societies. It is recommended that soil science societies collect, analyse and compare data on gender in the discipline so that progress can be evidenced, tracked and encouraged.</p>\u0000 </div>","PeriodicalId":12043,"journal":{"name":"European Journal of Soil Science","volume":"76 1","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ejss.70039","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142935118","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}

To minimize or prevent acidification, limestone was applied in two grain sizes: agricultural limestone with particles that were all &lt;3.15 mm and half of them &lt;0.80 mm, and fine-grained limestone with a median grain size of 2.5 μm. The amount of limestone applied corresponded to the theoretical acidity contained in the sulfides, as well as four times that amount. Another treatment included addition of peat to the low limestone dose to test its effects on immobilizing sufhur and metals. The pH of the drainage water and solid phase decreased to pH &lt;4.0 in the control, and to pH &lt;5.0 in the coarse-grained low-limestone treatment, but remained near-neutral in the other treatments. Hence, the fine-grained limestone effectively hindered acidity formation in contrast with the coarse-grained limestone when applied in amounts corresponding to the potential acidity held in the sulfides. The limestone treatments further overall decreased the rate of pyrite oxidation, slowed down the movement of the oxidation front, strongly minimized the formation of dissolved and solid-phase labile Al, and caused formation of gypsum as well as more labile secondary Fe(III) phases than corresponding Fe phases formed in the control. The limestone and peat treatments also caused shifts in the 16S rRNA gene-based microbial communities, where the control developed acidophilic iron and sulfur oxidizing communities that promoted acidity and metal release. Instead, the limestone-treated unacidified incubations developed acid tolerance to neutrophilic communities of iron and sulfur oxidizers that promoted sulfate formation without acidity release. The results showed that limestone treatments have several biogeochemical effects, and that using a fine-grained limestone as amendment was favourable in terms of minimizing acidity formation and metal release.</p>","PeriodicalId":12043,"journal":{"name":"European Journal of Soil Science","volume":"76 1","pages":""},"PeriodicalIF":4.0,"publicationDate":"2024-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ejss.70024","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142888251","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}

The conference program, focusing on soil fertility, was put together by experts from industry, academia, the Swiss Federal Office for the Environment, and the Food and Agricultural Organisation of the United Nations. The setting of this conference was unique as it brought together stakeholders from most if not all relevant areas engaged in the promotion of soil health: scientists, representatives from industry, the agricultural sector as well as the public and regulatory sector.&lt;/p&gt;&lt;p&gt;The contributions to this special issue of EJSS are meant to reflect the sprit, content, and topics discussed during this conference and gives tribute to the quality of science and interactions that took place. Healthy soils are in many ways the foundation of our economy, and our culture. They are not only a basis of our food production but also fulfil numerous other functions as they enable microbial, animal and plant biodiversity, purify and store water, and modulate increasingly alarming greenhouse gas emissions. Despite these well-known benefits, healthy soils are under pressure from intensive agriculture, sealing and pollution; from extreme environmental events; and from carbon loss. We therefore must develop means to sustain healthy soils, not only in Europe but across the world. What determines a healthy soil? How can we understand, monitor and maintain soil diversity? What is the underlying chemistry, biology and soil physical structure required to maintain sustainable crop cultivation and management? What are the main challenges to healthy soils? How is climate change challenging soil health, and how can healthy soils help mitigating climate change?&lt;/p&gt;&lt;p&gt;Over 30 international speakers, 40 poster presentations, and all participants addressed and discussed these topics and questions. The conference's opening lecture by Peter Wehrheim (European Commission, DG Research &amp; Innovation, Food Systems and Bioeconomy) provided a European perspective and highlighted the importance of the conference topic. His talk \"&lt;i&gt;The EU mission—A Soil Deal for Europe\"&lt;/i&gt; outlined how the mission will support the transition towards healthy soils by 2030 by putting in place an effective network of 100 living labs and lighthouses in rural and urban areas.&lt;/p&gt;&lt;p&gt;In the first session “Soil Diversity”, Peter Schad (TU Munich) and Sebastian Dötterl (ETH Zürich) presented the multiple environments on our planet which promote the formation of extremely diverse and fascinating soil types through physical and biological processes.&lt;/p&gt;&lt;p&gt;In the second session “Chemistry and Microbiology in Agronomical Soils for Sustainable Crop Cultivation”, Katie Field (University of Sheffield) discussed the effect of climate change on mycorrhizal fungi symbiosis function in crop fields and Elena Biagi (University of Bologna","PeriodicalId":12043,"journal":{"name":"European Journal of Soil Science","volume":"76 1","pages":""},"PeriodicalIF":4.0,"publicationDate":"2024-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ejss.70031","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142888253","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}

Although the former has been extensively studied, empirical information on the latter is scarce. Pot and field experiments were conducted at the University of Ghana's Forest and Horticultural Crops Research Centre (FOHCREC), Kade, Ghana, from May 2020 to December 2021 to quantify the short-term effect of the application of Greenlandic glacial rock flour (GRF) on the physical properties of three benchmark arable soils in Ghana, namely an Acrisol (sandy clay loam), a Haplic Ferralsol (sandy loam), and an Arenosol (sand). The pot experiment included three GRF treatments (0, 10, and 20 t ha⁻¹) and the three soil types, while the field experiment was conducted on only the sandy clay loam soil where GRF rates of 10 and 50 t ha⁻¹ were compared to the control. Intact 100 cm³ soil cores were sampled from the soil surface in the field and pot experiments to assess the soil bulk density. We also quantified soil water retention, air and gas transport, and pore morphological characteristics over a range of matric potentials. Both the pot and field experiments showed that adding GRF did not improve soil water retention. Still, the response of gas transport and pore characteristics to changing matric potential was significantly (<i>p</i> &lt; 0.05) modified by GRF in some soil types. The results suggested that the effectiveness of the use of GRF to ameliorate soil physical conditions for plant growth may depend on soil type and the soil water matric potential. We concluded that the application of GRF cannot be relied upon as a short-term strategy to significantly improve the structural quality of the tropical soils studied. Rather, GRF should be considered for application to the soils for its other beneficial effects. We recommend that the effects of repeated applications and further build-up of the material in the soil should be investigated to determine the effect of higher relative GRF concentrations on soil hydro-physical properties.</p>","PeriodicalId":12043,"journal":{"name":"European Journal of Soil Science","volume":"75 6","pages":""},"PeriodicalIF":4.0,"publicationDate":"2024-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ejss.70028","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142858439","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}

This research was conducted to approach the pedological recognition of viticulture zoning (on the farm scale) in a traditional and distinct viticultural region: Olite (Navarre). As grape yield and grape quality in a given field are generally variable and do not coincide one way or another, 13 soil profiles were selected for pedological description and analysis in an attempt to recognise the importance of soil properties. For that purpose, 45 soil samples (corresponding to the different pedogenetic horizons of the 13 soil profiles) were collected to improve zonal vineyard estimations. The most notable characteristics of the studied soils were the presence of petrocalcic horizons, high stone fragments content, mainly loamy textures, high pH (between 8.24 and 9.24), high carbonate (between 19.1% and 90.0%), and active limestone contents (between 5.7% and 26.1%), and relatively low organic matter contents (&lt;3.34%). Appreciable soil properties variability was detected from the results of this study and, therefore, variability in production and grape composition was expected. These results emphasise the spatial variability of the study area soils in a way that allows for the delineation of homogeneous viticultural zones.

Microbial biomass and community composition were quantified using phospholipid fatty acid (PLFA) analysis for unweathered and weathered parent rock materials, two RF fractions (8–16 mm and 2–8 mm) and the fine earth (FE; &lt;2 mm). Trends in biogeochemical weathering, nutrient availability and soil organic matter (OM) development were assessed using mineralogical, geochemical and physical analyses. Actinobacterial PLFA was particularly abundant in parent rocks, where Actinobacteria likely contribute to rock weathering and the initiation of OM accumulation. Conversely, bacterial PLFAs were most abundant in the FE under nutrient- and OM-rich conditions. The integral role of RFs as a microbial habitat is demonstrated by a distinct fungal colonisation, which is enabled by the specific physical features of RFs in combination with the provision of inorganic nutrients. Our findings indicate that RFs are colonised by microbes and that differences in the community structure depend on mineralogical properties and chemical weathering status. We document that RFs are microhabitats with a significant potential to host microbial life in cultivated soils, and thus, could play an important role in biogeochemical cycling and the provision of soil functions in agroecosystems.</p>","PeriodicalId":12043,"journal":{"name":"European Journal of Soil Science","volume":"75 6","pages":""},"PeriodicalIF":4.0,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ejss.70025","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142849143","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}

By integrating plant-beneficial bacteria (PBB) and Functional Annotation of Prokaryotic Taxa (FAPROTAX) databases, we show that rare species exhibited higher alpha diversity and multifunctionality than abundant species. Cropping enhanced the biodiversity of abundant functional bacteria in fine-textured soils, which promoted crop growth through increased PBB and carbon cycling. Conversely, rare functional bacteria exhibited consistently lower biodiversity in croplands. Random forest models and linear regression analyses identified land use as a significant factor influencing the biodiversity of rare functional bacterial communities, likely through plant–soil feedback systems.
