Soil degradation threatens global agriculture by compromising soil health, while sustainable agricultural management enhances soil functionality and carbon (C) storage, thereby contributing to climate change mitigation. This study estimates the feasible C sequestration potential of ten agricultural management practices across Europe, by applying practice‐specific emission factors and identifying areas suitable for additional implementation. For each management option, the implementation area was defined based on environmental and technical limitations and, if applicable, EU regulations. The objective of this study is to identify general patterns, relative magnitudes, and plausible ranges of carbon sequestration potentials across Europe. Considering soil C from 0 to 50 cm depth, biochar application shows the highest and most robust potential, contributing approximately 34%–47% of the total estimated annual C sequestration rate. This is followed by agroforestry, contributing 24%–45% (of which ~10% occurs in soils and ~90% in biomass), and zero tillage with 11%–15%. Optimised crop residue management (4%–6%), forage legumes and temporary ley rotations (4%–5%), and cover cropping (2%–3%) contribute comparatively smaller shares. Non‐inversion tillage and irrigation offered a marginal C sequestration potential. By implementing all non‐mutually exclusive management options, the greenhouse gas (GHG) mitigation potential is estimated at approximately 20%–30% of current, annual, agricultural GHG emissions in Europe (740 Mt. CO 2 e yr. −1 ), including the land‐use, land‐use change and forestry (LULUCF) sector. For the EU‐27, this corresponds to a similar range of 20%–31% of annual agricultural GHG emissions (614 Mt. CO 2 e yr. −1 ), also including the LULUCF sector. Evaluating trade‐offs and synergies of each management option is essential for achieving sustainable soil management. The success of C sequestration efforts in European agriculture depends on scaling up improved management practices. Meanwhile, soil C stocks decrease and entrenched policy as well as economic and other adoption barriers suggest that even the conservative scenario may be overly optimistic.

Biochar has emerged as a promising carbon dioxide removal (CDR) solution that combines long-term carbon storage with benefits for soil health, waste management, and industrial applications. This report provides a comprehensive assessment of the current state of biochar across feedstocks, production technologies, material properties, and end-use pathways, with a particular focus on its role in climate mitigation. Drawing on scientific literature and international case studies, the report evaluates the carbon sequestration potential, environmental performance, and technological maturity of biochar systems. It distinguishes between applications that deliver durable carbon removal and those that primarily contribute to emission reductions. The report further examines deployment barriers, including feedstock availability, regulatory frameworks, market development, and safety considerations, and reviews the status of biochar implementation across Mission Innovation countries. Based on these insights, it outlines key opportunities and recommendations to support the responsible scale-up of biochar as a climate solution.

Compost application is a widely recommended practice to maintain and improve soil fertility. However, such a practice could be a main entry path for plastic into soil. Accordingly, in the present work, two different compost samples, obtained with and without biochar, were analyzed to investigate how composting can affect the presence of microplastics (MPs). The substrate of both samples (consisting of a mixture of household food waste and animal manure) was also analyzed for comparative purposes. Samples were processed by oxidation, flotation, and filtration. MPs on the filters were observed, counted, and size-calibrated using both a stereomicroscope and an inverted microscope. MPs larger than 1 mm were further characterized by attenuated total reflectance Fourier-transformed infrared spectroscopy (ATR-FTIR). In parallel, mesoplastics (0.5–2 cm) were recovered from substrate and compost and extracted in methanol for testing in vitro cytotoxicity. The estimated concentration of MPs ranged from 820 to 1340 fragments/kg of dry sample, depending upon the sample. Three polymers represented the totality of identified plastic items: polyethylene (PE, including both low and high density), polyethylene terephthalate (PET), and polypropylene (PP) in order of abundance. Nevertheless, cytotoxicity was only observed in mesoplastic extracts from the substrate and could not be attributed to the identified plastic items themselves, suggesting that cytotoxic effects could have been caused by contaminants adsorbed to plastics or by the leaching of plastic additives during the extraction process. In summary, the composting process reduced the cytotoxicity of plastic extracts and the presence of MPs in compost, which could be attributed to the fragmentation of plastics.

Abstract The International Cooperative Programme on Integrated Monitoring of Air Pollution Effects on Ecosystems (ICP IM) presents a comprehensive long-term dataset of ongoing integrated ecosystem monitoring from European forested catchments. The dataset encompasses measurements from 46 monitoring stations across 14 European countries, with temporal coverage mostly extending from the early 1990s to 2020 (48 sites are currently active). The integrated monitoring approach applies over 20 monitoring subprogrammes to simultaneously measure physical, chemical, and biological properties across multiple ecosystem compartments including atmosphere, precipitation, throughfall, soil water, groundwater, runoff water, soil, vegetation, and biota. All measurements follow standardised protocols detailed in the ICP IM Manual, ensuring data quality and comparability across sites and time periods. The dataset supports research on ecosystem responses to air pollution, climate change impacts, and biogeochemical cycling. Data are available under a Creative Commons By Attribution (CC BY) licence, providing valuable long-term environmental monitoring data for the scientific community.

Studien undersøkte hvordan ulike dreneringssystemer (torpedo-, slisse- og tradisjonelle grøfter) påvirker hydrologi, nitrogentap, lystgassutslipp og avling av korn på marin leire. Bakgrunnen er økende nedbørintensitet som gjør god drenering nødvendig for å sikre avlinger. Forsøket ble gjennomført fra 2023 til 2025 på Grimsrud gård, Østfold der vannstrømning, jordfuktighet, nitrat i drensvann og klimagassutslipp ble målt. Tekniske problemer førte imidlertid til databrudd i flere sesonger. Hydrologiske data viste store variasjoner mellom både systemer og år. Torpedogrøftene hadde ofte noe høyere avrenning og langsommere tørkehastighet, trolig på grunn av høyere jordfuktighet og mulig jordpakking. Nitratmålinger viste ingen entydige forskjeller mellom systemene, og stor romlig variasjon mellom grøfter gjorde det vanskelig å beregne representative N‑tap. Sensorene viste karakteristiske nitratpulser under nedbør, men episodisk avrenning skapte usikkerhet. Lystgassmålingene viste gjennomgående høyere N₂O‑utslipp i torpedosystemet, særlig under våte forhold tidlig i sesongen. Dette indikerer økt denitrifikasjon i perioder med begrenset dreneringsytelse. Avlingsregistreringer viste ingen systematiske forskjeller mellom dreneringsmetodene. Samlet viser resultatene at forskjeller mellom systemene er vanskelige å dokumentere sikkert på grunn av stor naturlig variasjon og tekniske utfordringer. Videre overvåkning med forbedret måleoppsett anbefales for å kunne vurdere langtidseffekter på hydrologi og nitrogentap.

In semiarid regions, soil organic carbon (SOC) stocks and soil organic matter (SOM) pools are often low due to limited biomass input and inadequate management. This study evaluated SOC stocks and SOM fractions in a forage cactus–sorghum intercropping system irrigated with treated sewage water under diverse mulch in the northeastern Brazilian semiarid. The experiment followed a randomized split-plot block design with four replicates. Main plots included four irrigation levels (0, 80, 100, and 120 % of sorghum evapotranspiration (ETc)), and split plots comprised two mulch treatments: no mulch (NM) and mulch (WM) with 8 Mg ha−1 of sabi grass, spiny burrgrass, and goosegrass. Soil samples were collected at 0–0.10, 0.10–0.20, and 0.20–0.40 m depths in three sorghum cuts to determine labile SOM fractions: hot water-extractable C (HWEO-C), potassium permanganate-oxidizable C (POX-C), and particulate organic C (POC). In addition, SOC stocks and humic substances (HS), including humin (HU), fulvic acid (FA), and humic acid (HA), were determined at the end of the experiment. Intercropping system productivity was also evaluated. The highest SOC, POC, POX-C, and HWEO-C stocks occurred in 80WM and 100WM treatments, especially in HS, with HU as the dominant component. SOC in the HU fraction exceeded that in native vegetation soils, with threefold increases at 0–0.10 m and six-to sevenfold increases in deeper layers. Soils without irrigation, regardless of mulch, exhibited lower C storage, underscoring the importance of water management. Combining reclaimed water irrigation and mulching enhanced SOC accumulation, particularly in stable humic fractions, boosted carbon sequestration and crop productivity, and fostered sustainable, climate-resilient agriculture in semiarid tropical regions.
