However, less beneficial effects, such as a loss of soil organic carbon (SOC), are also associated with intensive tillage. This has made reduced and minimum tillage systems without ploughing increasingly popular in agriculture, contributing to soil health and climate change mitigation. We studied the effects of different tillage systems on chemical and microbial soil properties in a long-term field experiment established on a fine-sandy loamy Haplic Chernozem in Fuchsenbigl, Austria, in 1988. The tillage treatments include conventional tillage (CT) with a plough and a cultivator down to 30 cm soil depth, reduced tillage (RT) with a cultivator down to 15 cm two to three times a year, as well as minimum tillage (MT) treated with a rotary driller once a year down to 5–8 cm soil depth. In 2016, a soil sampling campaign was conducted, and alkaline phosphatase, phospholipid fatty acids (PLFAs), and the nitrogen (N) mineralisation potential were analysed along with chemical properties including SOC, active C, total nitrogen (N_t), CAL extractable phosphorus (P_CAL) and potassium (K_CAL). Under MT, these properties were significantly higher compared to CT in 0–10 cm. In deeper soil layers, these parameters showed very few significant differences between the tillage treatments. RT yielded intermediate values but not always significantly different from CT. PLFA indicators significantly correlated with SOC and, even more distinctly, with N_t and active carbon. The high ratio of Gram-positive to Gram-negative bacteria indicates more recalcitrant organic matter in the top layer in MT than CT.</p>","PeriodicalId":12043,"journal":{"name":"European Journal of Soil Science","volume":"76 1","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ejss.70037","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142968273","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}

Quantifying these changes is challenging and requires high spatial sampling densities or plant–soil experiments with highly distinct C isotopic signatures for plants and soils. Current methods for quantifying new SOM formation and RPEs rely on low labelling intensities, which introduces high levels of uncertainty. Here, we describe the design and operation of an experimental laboratory facility—BLOSOM (Botanical Labelling Observatory for Soil Organic Matter)—optimised for continuous ¹³C labelling of plants at high labelling intensities (&gt; 500‰) to quantify new SOM formation and RPEs in temperature-controlled soils from 216 experimental units. Throughout a &gt; 6-month experimental period, independent control of soil and air temperature was achieved across diurnal cycles averaging at 5.24°C ± 0.05°C and 21.4°C ± 1.2°C, respectively. BLOSOM can maintain stable CO₂ concentrations and δ¹³C isotopic composition within 5% of setpoints (CO₂: 440 ppm, δ¹³C: 515‰) across a &gt; 6-month period. This high-precision control on atmospheric enrichment enables the detection of new SOM formation with a total uncertainty of ±39% to ±3% for a theoretical range of 0.5%–10% new SOM formation, respectively.

These ecosystems play a critical role in supporting livestock with up to six times the forage productivity of the surrounding steppe and in storing over 69 g kg⁻¹ of organic carbon. However, the influence of soil structure parameters (e.g., pore size distribution, bulk density) and soil shrinkage behaviour on soil moisture variability and ecosystem functions in Patagonian wetlands remains poorly understood. This study aimed to assess the physical capacity and intensity parameters of soils, including shrinkage properties, within a micro-watershed in southern Patagonia. Our findings reveal significant spatial variability in soil properties, with bulk density (BD) ranging from 0.12 to 1.81 Mg m⁻³ across topographic positions. Mineral soils on summits and footslopes exhibited high macroporosity (up to 18.1% of total pore volume at 5 cm depth), which facilitates water movement, while organic soils in the Vega centre had a higher total porosity (up to 88.8%) that enhances water and air retention. The coefficient of linear extensibility (COLE) for organic soils reached a level of 0.078, indicating a high shrinkage capacity. This shrinkage influenced the functionality of the porous system, shifting pore roles between air conduction and water storage as larger pores contracted. These dynamics, driven by climate change and increased drying cycles, may lead to significant shifts in soil functionality and ecosystem resilience.

Insights from multiple stakeholder inquiries can provide a more nuanced understanding of conditions for soil health to support the adoption of sustainable soil management practices to meet national and regional goals. This article aimed to gather insights from stakeholders' perceptions of soil health and the state of soil knowledge in Denmark. Seven stakeholder inquiries, collected through a series of recent European soil research activities, were synthesised to identify perceptions of soil health, concerns about soil challenges and needs for harmonising production and use of knowledge related to sustainable soil management. Each inquiry was analysed individually, and common themes were discussed across topics. The data showed that the ecosystem service framework related to soil health was not evenly familiar across stakeholder categories. Identified concerns for soil health included climate change effects, knowledge transfer, economic pressure/risk, and soil challenges. The top ‘priority’ soil challenges identified were improving soil organic matter/peat soil, avoiding soil compaction and improving nutrient retention/use efficiency. Soil knowledge gaps related to soil challenges included: multidisciplinary and interdisciplinary long-term experiments, site-specific measures, science–policy–stakeholder interactions and knowledge feasibility at the farm level. Identified barriers preventing wider adoption of sustainable management practices included farm applicability of practices, farmers' engagement, knowledge sharing and lack of regulations for challenges such as soil compaction. Farmers were also concerned about the time and effort required to learn new practices, especially as it relates to their work/life balance and the challenge of implementing sustainable practices on commercial farms while ensuring profitability. These concerns might partially arise from knowledge gaps between stakeholder categories.

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.

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 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.
