Data from: Taxonomic survey of Agaricomycetes (Fungi: Basidiomycota) in Ontario tallgrass prairies determined by fruiting body and soil rDNA sampling
The fungal composition of North America's grasslands is poorly known, but an important area of study due to grassland conservation concerns and their close relation to agricultural lands. This study is a survey of Agaricomcyetes from fifteen diverse tallgrass prairies across southwestern Ontario, determined through fruiting body surveys (above-ground) and next-generation sequencing of soil ribosomal DNA (below-ground), and makes comparisons between the results of these two techniques. The most species rich taxa were the Clavariaceae, Hygrophoraceae, and Entolomataceae, each detected by both techniques, with the addition of the Sebacinaceae and Polyporaceae sensu lato below-ground, and Hymenogastraceae (Hebeloma spp.) and Mycenaceae above-ground. Many of the most abundant species belonged to these species-rich taxa and were highly abundant by either technique. The above-ground surveys found at least 73 species and the below-ground technique 238 operatonal taxonomic units. Although many fine-scale taxa (species and approximate families) were unique to one technique or the other (only eight genetic species were shared between both), the below-ground technique uncovered a greater breadth of higher taxa (mostly equivalent to orders), including ones undetected by the above-ground technique. A review of grassland fungi surveys around the world shows many similarities and the potential for grassland fungal conservation in North America. Given current technological advancements and grassland conservation concerns, it is prudent to further study North America's grassland fungi.
Data from: Domesticated tomatoes are more vulnerable to negative plant-soil feedbacks than their wild relatives
Domesticated plants can differ from their wild counterparts in the strength and outcome of species interactions, both above- and belowground. Plant-soil feedbacks influence plant success, and plant-associated soil microbial communities can influence plant interactions with herbivores and their natural enemies, yet, it is unclear if domestication has changed these relationships. To determine the effects of domestication on plant-soil interactions, we characterized soil microbial communities associated with various cultivars of domesticated tomato and some of its wild relatives. We measured the strength and direction of plant-soil feedbacks for domesticated and wild tomatoes, and the effects of soil on plant resistance to specialist herbivory by Manduca sexta, and the attraction of a parasitoid wasp, Cotesia congregata. Domesticated tomatoes and their wild relatives had negative plant-soil feedbacks, as conspecifics cultivated soil that negatively impacted performance of subsequent plants (longer germination time, lower biomass) than if they grew in non-tomato soils. Significant variation existed among domesticated and wild tomato varieties in the strength of these feedbacks, ranging from neutral to strongly negative. For aboveground plant biomass, tomato wild relatives were unaffected by growing in tomato-conditioned soil while domesticated tomatoes grew smaller in tomato soil, indicating effects of plant domestication. Overall, increased microbial biomass within the rhizosphere resulted in progressively less-negative plant-soil feedbacks. Plant cultivars had different levels of resistance to herbivory by M. sexta, but this did not depend on plant domestication or soil type. The parasitoid C. congregata was primarily attracted to herbivore damaged plants, independent of plant domestication status, and for these damaged plants, wasps preferred some cultivars over others, and wild plants grown in tomato soil over wild plants grown in non-tomato soil. Synthesis: These results indicate that crop tomatoes are more likely to show negative plant-soil feedbacks than wild progenitors, which could partially explain their sensitivity to monocultures in agricultural soils. Further, cultivar-specific variation in the ability to generate soil microbial biomass, independent of domestication status, appears to buffer the negative consequences of sharing the same soil. Last, soil legacies were relatively absent for herbivores, but not for parasitoid wasps, suggesting trophic level specificity in soil feedbacks on plant-insect interactions.

Data from: Annual ryegrass (Lolium multiflorum Lam.) growth response to nitrogen in a sandy soil amended with acidified manure and municipal sludge after "Quick Wash" treatment
<p>The Quick Wash (QW) treatment extracts phosphorus (P) from manure and municipal sludge (MS), producing an organic acidified by-product with adequate nitrogen (N):P ratio to meet crop N requirements. Yet, data on crop response to N using QW by-products are lacking. We evaluated the response of annual ryegrass (<span class="html-italic">Lolium multiflorum</span> Lam.) and potential N leaching in sandy soil to N applications using raw wastes, their corresponding QW by-products, and ammonium sulfate (AMS) fertilizer. Treatments included a control (no amendment added), raw and acid-washed chicken litter, dairy and swine manure, MS, and AMS at 100, 200, and 400 kg N ha<sup>−1</sup>.</p>
Data for: Stabilisation of soil organic matter with rock dust partially counteracted by plants
<p class="MsoNormal">In this study, the effect of rock dust addition on both soil inorganic and organic carbon contents was investigated. Soil chemical changes were measured, including soil organic carbon (totals and fractions), soil inorganic carbon, pH, electric conductivity, and water-extractable and ammonium acetate-extractable ion levels (Ca, Mg, Al, Fe, Mn, Fe, Zn, Si). In addition, the effect of plants on soil chemistry and rocks on plant growth (biomass) and plant ion uptake was studied. The results demonstrated rock weathering during the 6 months incubation period and a stabilisation of organic carbon. Plants partially counteracted the stabilisation of soil organic carbon. This was attributed to interactions between soil chemical changes induced by rock dust, plant exudation, and subsequent soil organic carbon stabilisation mechanisms.</p>
Data for: Methodological choices in size and density fractionation of soil carbon reserves – A case study on wood fiber sludge amended soils
<p>A myriad of methods is currently being applied in soil carbon research encompassing major variation in the basic principles and minor variation in details. The most proper method is dependent on the research question and soil type, wherefore a consensus will likely never be reached, and it is difficult to label any method inappropriate. Both the fundamental and the subtle choices in methodology affect the results, wherefore increasing the method-related understanding of soil, agricultural and environmental scientists is of utmost importance. In scientific literature, methods are often not thoroughly presented, let alone reasoned. With this data, we discuss methodological choices in soil carbon fractionation. In addition, our case study follows the effects of pulp mill sludge amendments on soil carbon in a Luvic Stagnosol and Dystric Arenosol. Organic materials are being applied to soil to increase productivity and soil carbon storage. Our results show the difficulties of accumulating carbon in the stable, mineral associated pool, when the carbon content is initially relatively high, and the sorption capacity of the mineral phase already largely occupied. </p>

Data from: Interactive effects of soil moisture, air temperature and litter nutrient diversity on soil microbial communities and Folsomia candida population
<p>Soil organisms play a key role in carbon and nutrient cycling in forest ecosystems. While soil organisms are strongly influenced by litter chemistry and are highly sensitive to abiotic conditions, little is known about how the interactive effects of these two factors. To address this gap in knowledge, we conducted a 10-week microcosm experiment in which we simulated the effects of climate change on soil ecology. More specifically, we studied relationships among litter nutrient concentration, microbial biomass, Collembola demographic parameters, and litter decomposition, exploring the potential impacts of increasing air temperature and decreasing soil moisture. To develop a gradient of nutrient concentrations, we created six tree litter mixtures with materials gathered from <em>Quercus pubescens</em> and its companion species. In contrast to microbes, we observed that Collembola abundance and litter decomposition were interactively affected by soil moisture and air temperature: the negative effect of increasing air temperature on Collembola abundance was amplified by reduced soil moisture, whereas the positive effect of increasing air temperature on litter decomposition disappeared under reduced soil moisture conditions. In contrast to fungi, the response of bacterial biomass and Collembola abundance to litter nutrient concentration was dependent on abiotic conditions. More specifically, the relationships between nutrients, especially calcium and magnesium, and bacterial biomass and Collembola abundance were less robust or disappeared under drier or warmer conditions. In conclusion, our findings underscore that ongoing climate change could affect soil organisms directly as well as indirectly, by altering their responses to litter nutrient concentrations. In addition, we found that nutrient-rich habitats might be more affected than nutrient-poor habitats by altered climatic conditions.</p>

Field data of soil greenhouse gas fluxes from SOMMIT long-term experiments
<p>This is a database of field data of soil greenhouse gas fluxes and ancillary data from long-term experiments (LTEs) that participated in the task 1 of the work package 3 from SOMMIT. As of November 2024 (V 1.0) six LTEs have contributed with data: "ACBB Estrées-Mons, France", "Rutzendorf_17, Austria", "Maintainance of organic orchards, Italy", "Fagna, Italy", "ULBF-Ljubljana, Slovenia" and "Grabow 2, Poland". All LTEs are referenced according to the LTE Index from <a href="https://doi.org/10.5281/zenodo.7598122" target="_blank" rel="noopener">https://doi.org/10.5281/zenodo.7598122</a>. The data includes soil greenhouse gas fluxes (N2O, CO2 and CH4) under different management practices, as well as ancillary data that might be useful to explain the observed fluxes. The database includes metadata on how soil greenhouse flux data and ancillary data were collected. Individual soil gas flux estimates are also expressed in CO2 equivalents [mg CO2-eq m-2 h-1], thereby providing a dataset on the contribution of soil CO2, N2O and CH4 fluxes to the soil global warming potential. This product is part of the EJP SOIL internal project SOMMIT, and serves as deliverables WP3.2 and WP3.3.</p>
