Soils provide essential ecosystem services and represent the most diverse habitat on Earth. It has been suggested that the presence of various physico-chemically heterogeneous microhabitats supports the enormous diversity of microbial communities in soil. However, little is known about the relationship between microbial communities and their immediate environment at the micro- to millimetre scale. In this study, we examined whether bacteria, archaea, and fungi organize into distinct communities in individual 2-mm-sized soil aggregates and compared them to communities of homogenized bulk soil samples. Furthermore, we investigated their relationship to their local environment by concomitantly determining microbial community structure and physico-chemical properties from the same individual aggregates. Aggregate communities displayed exceptionally high beta-diversity, with 3\uffe2\uff80\uff934 aggregates collectively capturing more diversity than their homogenized parent soil core. Up to 20%\uffe2\uff80\uff9330% of ASVs (particularly rare ones) were unique to individual aggregates selected within a few centimetres. Aggregates and bulk soil samples showed partly different dominant phyla, indicating that taxa that are potentially driving biogeochemical processes at the small scale may not be recognized when analysing larger soil volumes. Microbial community composition and richness of individual aggregates were closely related to aggregate-specific carbon and nitrogen content, carbon stable-isotope composition, and soil moisture, indicating that aggregates provide a stable environment for sufficient time to allow co-development of communities and their environment. We conclude that the soil microbiome is a metacommunity of variable subcommunities. Our study highlights the necessity to study small, spatially coherent soil samples to better understand controls of community structure and community-mediated processes in soils.Drylands (hyperarid, arid, semiarid, and dry subhumid ecosystems) cover almost half of Earth\uffe2\uff80\uff99s land surface and are highly vulnerable to environmental pressures. Here we provide an inventory of soil properties including carbon (C), nitrogen (N), and phosphorus (P) stocks within the current boundaries of drylands, aimed at serving as a benchmark in the face of future challenges including increased population, food security, desertification, and climate change. Aridity limits plant production and results in poorly developed soils, with coarse texture, low C:N and C:P, scarce organic matter, and high vulnerability to erosion. Dryland soils store 646 Pg of organic C to 2\uffe2\uff80\uff89m, the equivalent of 32% of the global soil organic C pool. The magnitude of the historic loss of C from dryland soils due to human land use and cover change and their typically low C:N and C:P suggest high potential to build up soil organic matter, but coarse soil textures may limit protection and stabilization processes. Restoring, preserving, and increasing soil organic matter in drylands may help slow down rising levels of atmospheric carbon dioxide by sequestering C, and is strongly needed to enhance food security and reduce the risk of land degradation and desertification.e.g. carbon sequestration) over a significative timeframe. Remediation of polluted soils is not in scope. The field experiments shall take place under dynamically, meteorologically and biologically complex conditions.

This is going to require the development and rapid scaling of new forms of carbon management. When developing new CDR techniques, it is essential to ensure that there is complete accounting of how the process affects greenhouse gas fluxes. Enhanced weathering (EW), the spreading of finely ground weatherable, cation-rich crushed rocks to soils, has the potential to sequester significant amounts of CO2 while improving soil health. However, the effect of EW affiliated increases in soil pH on soil organic carbon (SOC) decomposition and CO2 efflux from soils remain debated. It has been proposed that increasing soil pH can lead to enhanced SOC remineralization. To move forward this debate, we present CO2 flux and soil carbon pool data from a greenhouse study in large mesocosms. We focused on mildly acidic soil in which, on short time scales, cations from weathering quantitively move into the exchangeable fraction in soils. Therefore, gas fluxes changes should be largely linked to changes in SOC stores. We find no significant correlation between CO2 fluxes and soil pH and no significant correlation between CO2 fluxes and rock application. Although this does not rule out a link between soil pH and SOC remineralization rates, the effect is small relative to other factors, like temperature and soil moisture. Although minor increases in total inorganic carbon were observed in basalt-amended soils, these increases did not support a direct link between soil pH and increased CO2 emissions. We observed a small increase in soil total organic carbon stocks in basalt amended mesocosms, but this change was also not significant enough to drive a shift in observed soil CO2 fluxes.", "keywords": ["soil organic carbon", "enhanced weathering", "carbon dioxide removals", "co2", "CO2", "Enhanced weathering"], "contacts": [{"organization": "Chiaravalloti, Isabella, Zhang, Shuang, Planavsky, Noah,", "roles": ["creator"]}]}, "links": [{"href": "https://doi.org/10.5281/zenodo.14947845"}, {"rel": "self", "type": "application/geo+json", "title": "10.5281/zenodo.14947845", "name": "item", "description": "10.5281/zenodo.14947845", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/10.5281/zenodo.14947845"}, {"rel": "collection", "type": "application/json", "title": "Collection", "name": "collection", "description": "Collection", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main"}], "time": {"date": "2025-03-04T00:00:00Z"}}, {"id": "10.5281/zenodo.15077441", "type": "Feature", "geometry": null, "properties": {"updated": "2026-04-03T16:24:44Z", "type": "Dataset", "created": "2025-04-24", "title": "Permafrost thaw reverses soil carbon age profiles and extends transit time in an Arctic tundra soil", "description": "unspecifiedA vertically-resolved model was developed and optimized against radiocarbon (14C) data from a 25-year snow manipulation experiment to quantify how deeper snow affects soil carbon age, transit time, and redistribution in Arctic permafrost.", "keywords": ["soil organic carbon", "Age", "Carbon dioxide", "transit time", "radiocarbon", "Permafrost", "Arctic ecosystem", "Carbon", "Alaska"], "contacts": [{"organization": "Tangarife Escobar, Andres, Pedron, Shawn Alexander, Czimczik, Claudia I., Metzler, Holger, Gonz\u00e1lez Sosa, Maximiliano, Welker, Jeffrey, Guggenberger, Georg, Sierra, Carlos,", "roles": ["creator"]}]}, "links": [{"href": "https://doi.org/10.5281/zenodo.15077441"}, {"rel": "self", "type": "application/geo+json", "title": "10.5281/zenodo.15077441", "name": "item", "description": "10.5281/zenodo.15077441", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/10.5281/zenodo.15077441"}, {"rel": "collection", "type": "application/json", "title": "Collection", "name": "collection", "description": "Collection", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main"}], "time": {"date": "2025-03-24T00:00:00Z"}}, {"id": "10.5281/zenodo.15133040", "type": "Feature", "geometry": null, "properties": {"updated": "2026-04-03T16:24:45Z", "type": "Dataset", "title": "InfoCarb:\u00a0Forest Inventory of the Autonomous Province of Trento (Trentino), Italy", "description": "InfoCarb: Forest Inventory of the Autonomous Province of Trento (Trentino), Italy\u00a0 Forest Carbon Stocks in the Province of Trento inventory of Trentino based on 150 plots (15 m radius) over 6200 Km2 land area.

To address this knowledge gap, we sampled 253 sites at a regional scale across tropical savannas in Kruger National Park, South Africa, covering broad gradients in fire regimes, grass biomass, rainfall, and soil texture. We demonstrate that across these savannas, pyrogenic carbon contributes, on average, 14.08% (se = 0.36%, n = 253) of total SOC storage in surface soils but can reach as high as 40%.

In this three-factorial experiment, a reduced tillage system with a chisel plough to a depth of 10 cm is compared to conventional ploughing to a depth of approx. 20 cm, a liquid manure system is compared to a compost manure system and the adding of biodynamic preparations is compared to none preparations. Biodynamic preparations had been assessed previously in system comparison experiments, however, their effect is difficult to elucidate separately in a system comparison approach. One reason for setting up this experiment was therefore a demand among farmers and researchers in early 2000 to disentangle the influence of biodynamic preparations from the influence of manure compost on soil fertility. On the other hand, it should be tested if and how reduced tillage is feasible in organic farming.\u00a0This dataset consists of plot data for yield, soil and management from 2002 to 2018. The crop rotation at the start of the experiment was winter wheat, sunflower, spelt and two years of grass clover. Sunflower was excluded after 2010 because of total yield loss due to slugs. For yield, total aboveground plant biomass is given for silage maize, grass-clover and cover crops, grain yield for winter wheat, spelt and sunflowers. Total nitrogen and phosphorus contents of the yield components are given as well. Weed data is given as total weed cover and/or total weed biomass in the years with row crops. For pests and diseases, Fusarium toxins (DON) are given for 2003 and slug emergence for 2010.

Topsoil and subsoil SOC stocks were calculated by the equivalent soil mass method for one individual sampling campain in 2018.\u00a0 Cattle manure (CM) application led to the most significant SOC storage, increasing topsoil SOC stock and content by approximately 20% over the long term. Other individual OM management practices \u2013 pig slurry (PS) application, cereal straw incorporation and cover crops (CC) cultivation \u2013 induced smaller, non-significant SOC increases of about 5%. Nevertheless, their combined effects were cumulative, resulting in significant SOC accruals. In contrast to the topsoil, SOC stock in the subsoil was unaffected by the OM management practices. Annual humified C inputs calculated from the amount and quality of livestock manures and (cover) crops residues correlated strongly with SOC content in the topsoil (r=0.8), which underlines that the amount and quality of C inputs are key drivers of SOC storage. Changes in N fertilization over time and N fertilization adjustments among treatments significantly affected SOC dynamics. This highlights the complexity of interpreting time series of data from LTEs, for which the evolution of management practices over time may act as confounding factors.", "keywords": ["Crop residues", "Crop yields", "Livestock manures", "Cover crops", "C inputs", "Long-term field experiment", "Organic matter practices", "Organic carbon"], "contacts": [{"organization": "Sail, Simon", "roles": ["creator"]}]}, "links": [{"href": "https://doi.org/10.5281/zenodo.15609417"}, {"rel": "self", "type": "application/geo+json", "title": "10.5281/zenodo.15609417", "name": "item", "description": "10.5281/zenodo.15609417", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/10.5281/zenodo.15609417"}, {"rel": "collection", "type": "application/json", "title": "Collection", "name": "collection", "description": "Collection", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main"}], "time": {"date": "2025-07-02T00:00:00Z"}}, {"id": "10.5281/zenodo.15686591", "type": "Feature", "geometry": null, "properties": {"updated": "2026-04-03T16:24:59Z", "type": "Dataset", "created": "2005-06-18", "title": "Soils of silvopastoral system in Southern Brazil", "description": "Dataset of the paper 'Total carbon and nitrogen stocks and the granulometric fractions of organic matter in soils of silvopastoral system with tree nuclei in Southern Brazil' ofFiliation:\u00a0 1 Universidade Federal de Santa Catarina (UFSC), Centro de Ci\u00eancias Agr\u00e1rias (CCA), Programa de P\u00f3s-Gradua\u00e7\u00e3o em Agroecossistemas (PGA), Florian\u00f3polis, Santa Catarina, Brasil. 2 Universidade de S\u00e3o Paulo (USP), Centro de Energia Nuclear na Agricultura (CENA), Programa de P\u00f3s-Gradua\u00e7\u00e3o em Agroecossistemas (PGA), Florian\u00f3polis, Santa Catarina, Brasil *Corresponding Author: arcangelo.loss@ufsc.br", "keywords": ["Soil", "Nitrogen", "Pasture", "Carbon"], "contacts": [{"organization": "Loss, Arc\u00e2ngelo", "roles": ["creator"]}]}, "links": [{"href": "https://doi.org/10.5281/zenodo.15686591"}, {"rel": "self", "type": "application/geo+json", "title": "10.5281/zenodo.15686591", "name": "item", "description": "10.5281/zenodo.15686591", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/10.5281/zenodo.15686591"}, {"rel": "collection", "type": "application/json", "title": "Collection", "name": "collection", "description": "Collection", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main"}], "time": {"date": "2025-06-18T00:00:00Z"}}, {"id": "10.5281/zenodo.15687463", "type": "Feature", "geometry": null, "properties": {"updated": "2026-04-03T16:24:59Z", "type": "Dataset", "title": "Nitrogen and phosphorus distribution in global agricultural soils", "description": "Total organic carbon, total nitrogen, total phosphorus, and available N and P in global agricultural soils", "keywords": ["Elemental stoichiometry", "Soil organic carbon", "Soil fertility"], "contacts": [{"organization": "Luo, Lei", "roles": ["creator"]}]}, "links": [{"href": "https://doi.org/10.5281/zenodo.15687463"}, {"rel": "self", "type": "application/geo+json", "title": "10.5281/zenodo.15687463", "name": "item", "description": "10.5281/zenodo.15687463", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/10.5281/zenodo.15687463"}, {"rel": "collection", "type": "application/json", "title": "Collection", "name": "collection", "description": "Collection", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main"}], "time": {"date": "2025-06-18T00:00:00Z"}}, {"id": "10.5281/zenodo.15720421", "type": "Feature", "geometry": null, "properties": {"updated": "2026-04-03T16:24:59Z", "type": "Dataset", "title": "Dataset for paper: Bacterial and Fungal Communities Respond Differently to Changing Soil Properties Along Afforestation Dynamic", "description": "Bacterial and Fungal Communities Respond Differently to Changing Soil Properties Along Afforestation Dynamic.

Many microorganisms synthesise carbon (C)-rich compounds under resource deprivation. Such compounds likely serve as intracellular C-storage pools that sustain the activities of microorganisms growing on stoichiometrically imbalanced substrates, making them potentially vital to the function of ecosystems on infertile soils. We examined the dynamics and drivers of three putative C-storage compounds (neutral lipid fatty acids [NLFAs], polyhydroxybutyrate [PHB], and trehalose) across a natural gradient of soil fertility in eastern Australia. Together, NLFAs, PHB, and trehalose corresponded to 8.5\uffe2\uff80\uff9340% of microbial C and 0.06\uffe2\uff80\uff930.6% of soil organic C. When scaled to \uffe2\uff80\uff9cstructural\uffe2\uff80\uff9d microbial biomass (indexed by polar lipid fatty acids; PLFAs), NLFA and PHB allocation was 2\uffe2\uff80\uff933-times greater in infertile soils derived from ironstone and sandstone than in comparatively fertile basalt- and shale-derived soils. PHB allocation was positively correlated with belowground biological phosphorus (P)-demand, while NLFA allocation was positively correlated with fungal PLFA : bacterial PLFA ratios. A complementary incubation revealed positive responses of respiration, storage, and fungal PLFAs to glucose, while bacterial PLFAs responded positively to PO43-. By comparing these results to a model of microbial C-allocation, we reason that NLFA primarily served the \uffe2\uff80\uff9creserve\uffe2\uff80\uff9d storage mode for C-limited taxa (i.e., fungi), while the variable portion of PHB likely served as \uffe2\uff80\uff9csurplus\uffe2\uff80\uff9d C-storage for P-limited bacteria. Thus, our findings reveal a convergence of community-level processes (i.e., changes in taxonomic composition that underpin reserve-mode storage dynamics) and intracellular mechanisms (e.g., physiological plasticity of surplus-mode storage) that drives strong, predictable community-level microbial C-storage dynamics across gradients of soil fertility and substrate stoichiometry.
