Background: Soil microbes play a central role in nutrient recycling in soils: however, the genetic mechanisms governing their responses to long-term fertilization remain poorly understood. While the agronomic benefits of long-term fertilization are well-documented, the genetic mechanisms and ecological processes underlying microbial community responses to different fertilization regimes remain poorly understood, particularly in unique soil systems such as black soils (Mollisols), which are critical for global food security. A deeper insight into how organic and inorganic fertilizers influence microbial assembly, functional potential, and community stability is essential for developing sustainable soil management practices. Results: This study deciphers microbial assembly mechanisms, functional gene dynamics, and community restructuring in black soils subjected to 44 years of chemical fertilizer (CF), manure amendment (M), and integrated chemical fertilizer with manure (CFM) treatments. Results revealed that CF significantly enhances functional gene abundance related to carbon (C) degradation (e.g., starch, cellulose, chitin and lignin) and nitrification, accelerating the conversion of recalcitrant C to labile C pools and ammonium to nitrate. Conversely, M and CFM treatments promote microbial diversity and stability while decelerating nutrient transformation processes. In addition, microbial assembly mechanisms shift from stochastic to deterministic processes with long-term fertilizer application in CF. The structural equation modeling (SEM) indicated that soil chemical properties shape both the diversity and composition of taxonomic and functional gene communities which subsequently regulate microbial -mediated nutrient cycling processes and crop yield. Conclusions: Our findings highlight the trade-offs between microbial functional potential and community stability under contrasting fertilization strategies, emphasizing the need to integrate microbial metrics into sustainable land management frameworks.

Traditional orchards are one of the most well-known examples of multifunctional farming. They have a long history of providing different fruits and combining various other agricultural activities, such as extensive animal farming, with cultural significance that reflect the different regional landscapes of Europe. Objectives This study investigates the extent of traditional orchards and addresses their cultural significance and their contribution to the Sustainable Development Goals in the context of multifunctional agricultural landscapes. Method The presented work combines an expert survey conducted in ten EUCALAND network member countries by means of both a standardised and a more detailed questionnaire to compare and summarize the situation of traditional orchards in these countries. Results The results show that traditional orchards are diminishing on the European scale but still have huge significance in many regions. Provisioning ecosystem services, such as fruit production, are valued in terms of disease resistance and genetic diversity which is likely to be of increasing importance in the context of future climate change and concerns over food security. The most important drivers for maintaining traditional orchards appears to be based on cultural ecosystem services and the benefits they provide to society, including the preservation of traditions and regional identity, attractive places for recreation, aesthetic appreciation, inspiration for artists. The examples of best practices from the contributing countries all reveal the close connection of these orchards to local communities and to often specific traditional knowledge. Conclusion The presented review of the current situation for these important components of the agricultural landscape as well as country-specific management characteristics has the potential to inspire other countries to maintain their traditional orchards.

Weed seeds are potential contaminants of composts derived from biowastes. We assessed the effect of steam treatment alone and in combination with composting on the mortality of barnyardgrass [ Echinochloa crus-galli (L.) P. Beauv.] seeds in a biowaste substrate consisting of a mixture of onion ( Allium spp.) waste (60%), horse ( Equus spp.) manure (20%), and wood shavings (20%). In the first study, seeds of six populations of E. crus-galli exposed to temperatures ranging from ca. 60 to 99 C followed by a 3-min residence time exhibited a decline in seed germination from approximately 25% to 0%. The E. crus-galli populations varied greatly in germinability and responded differently to high temperatures. Samples with lower germinability as assessed in controls were killed at lower temperatures than samples with higher initial germinability. However, to ensure an almost 100% kill of all seeds in the populations, a mean temperature of 100 C was necessary. In another study, seed germination was assessed after steaming the biowaste mixture to a mean temperature of about 60 C and subsequently composting. A short steaming period of the biowaste mixture at approximately 60 C before composting was unnecessary, as all composted seed samples, including the non-steamed control seeds, died during the composting process.

Optimizing manure use and reducing chemical fertilizers are crucial for achieving the Sustainable Development Goals. However, optimal manure redistribution for cropland yield, nitrogen emissions, and greenhouse gas benefit remains unclear at large spatial scales. Here, we employed genetic algorithms and meta-analysis to obtain an optimal substitution rate for major crops in China. This could reduce synthetic nitrogen use and reactive nitrogen pollution by 13.3 and 2.0 Tg, cut ammonia and nitrous oxide emissions by 15.6% and 16.2%, and lower nitrogen runoff and leaching by 32.9%. The yield of eight major upland crops could be increased by 2.0-19.5%. The strategy involves relocating about 255 million pig equivalents, with 32.3% moved across provinces, mainly from central to northern and northeastern China. An estimated US$6.1 billion investment in livestock relocation could yield US$25.9 billion in benefits.

Water quality degradation is a major issue in Mediterranean regions, but identifying the key natural and human drivers remains challenging, requiring large–scale studies for meaningful synthesis and comparison. This study analyzed a vast Mediterranean dataset spanning 89,015 across 15 Iberian river basins along a climate gradient (cooler-wetter north to warmer-drier south), 3 decades, 3441 stations, 19 parameters, and 15 million observations. It is the first study of this scale in the region, utilizing custom scripts for automated data compilation and processing. The study revealed an evident north–to–south water quality decline, with rising electric conductivity, pH, total suspended solids, nitrogen, phosphorus, organic carbon, and sulphate, alongside reduced dissolved oxygen and transparency. This pattern correlated with the latitudinal climate gradient and intensified agriculture in the south (Pearson correlation coefficient: 0.1 to 0.53; Spearman's rank correlation coefficient: 0.17 to 0.56), while increased forest cover had a mitigating effect (Pearson: −0.50 to −0.07; Spearman: −0.51 to −0.10). Multidecadal trend analysis revealed a shift around 2005 with most parameters decreasing, except for nitrate and phosphate, which rose likely due to the 2004/05 drought reducing river dilution and expanded irrigated agriculture, especially in Alentejo with the Alqueva reservoir. These findings are crucial for guiding future national management actions and pollution reduction initiatives in Mediterranean regions, aligning with the European Commission's “European Green Deal” that targets a 50 % reduction in nutrient losses to make agriculture more environmentally sustainable, and also provide a valuable reference to many other regions with similar challenges for water quality management.

Surface displacement caused by natural and anthropogenic activities poses a significant risk to subsurface pipelines, particularly in areas experiencing subsidence. Stress and strain induced by deformation can lead to pipeline buckling and potential vulnerability. This study applies a multidisciplinary approach integrating interferometric synthetic aperture radar (InSAR) deformation analysis, well data, and geological context to assess the risk to oil and gas pipelines in Iran’s Qazvin plain. The focus is on evaluating the impact of an unconfined aquifer, which has a lower risk of subsidence compared to a confined aquifer, on pipeline infrastructure. We analyzed multitemporal Sentinel-1 data collected between 2014 and 2021. Our findings reveal that 2,400 km 2 of the study area is experiencing subsidence with vertical rates reaching up to 14 cm/year with an average S k {S}_{{\rm{k}}} , or skeletal storage value of 0.04. We explore the reasons for this unexpectedly high subsidence, finding that compressible unconfined aquifers with historically low water levels are also at risk for significant inelastic, or permanent, subsidence. We also evaluate pipeline profiles, which show spatial subsidence, much higher than typically seen in unconfined aquifers, with variations of up to 1 m, indicating long-term risks to the infrastructure. This study demonstrates the potential of InSAR techniques in assessing the risk to critical infrastructure, such as oil and gas pipelines, in regions with land deformation due to groundwater withdrawal. Our approach underscores the importance of continuous monitoring and offers valuable insights for addressing the challenges posed by subsidence on pipeline infrastructure.

Biodiversity in human-dominated landscapes is declining, but evidence-based conservation targets to guide international policies for such landscapes are lacking. We present a framework for informing habitat conservation policies based on the enhancement of habitat quantity and quality and define thresholds of habitat quantity at which it becomes effective to also prioritize habitat quality. We applied this framework to insect pollinators, an important part of agroecosystem biodiversity, by synthesizing 59 studies from 19 countries. Given low habitat quality, hoverflies had the lowest threshold at 6% semi-natural habitat cover, followed by solitary bees (16%), bumble bees (18%), and butterflies (37%). These figures represent minimum habitat thresholds in agricultural landscapes, but when habitat quantity is restricted, marked increases in quality are required to reach similar outcomes.

Despite the increasing popularity of wind power farms this kind of energy production has been contested, citing cultural, economic, and sometimes even environmental reasons – especially when such power farms are built in areas of significant environmental value and status, as is the case of several areas in the High North. One way to explore this conflict is through understanding the effects of such projects on local ecosystem services (e/s) – i.e., the direct and indirect benefits that ecosystems provide to support and sustain human livelihoods. This article discusses the perceived consequences on e/s after the development of a wind power farm in a Northern Norwegian context (High North), at the area of Kvitfjell/Raudfjell on the island of Kvaløya. Following a mixed-methods approach, combining exploratory data analysis (EDA) with thematic and sentiment analysis, the article presents a recent survey among various actors and stakeholders in the examined area to explore how they perceived the effects of the newly constructed wind power farm on e/s. Our results illustrate that a significant portion of the respondents maintained a critical and even apprehensive attitude on the wind farm development, although some positive economic impacts to the local community were also acknowledged.
