AUGMENTING SEQUENCING TECHNOLOGY FOR BETTER INFERENCE IN SOIL MICROBIOME ANALYSIS
… of DNA sequencing revolutionized the field of microbiome research. Many organisms, by virtue of their codependence and/or growth rate, are either impossible or extremely challenging to get into pure culture. Sequencing allows important taxonomic and phylogenetic information to be obtained …

Characterizing plant biostimulants and their impact on the soil microbiome and productivity of maize
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2022-11-11 without embargo terms

Global meta-analysis and metagenomics approach on the soil microbiome associated with cover cropping
Soil nutrient loss is one of the major causes of soil degradation that threatens future global food security. Cover cropping is a promising sustainable agricultural method with the potential to enhance soil health and mitigate consequences of soil degradation. As one of the agricultural practices …

Impact of soil contamination by PFAS on pathogenic Escherichia coli O157:H7 physiology and the soil microbiome
Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2027-05-01

Combined effects of warming and drying on a temperate-to-boreal forest ecotone exert additive changes on soil microbiome structure and diversity
The soil microbial community is an important mediator of many ecosystem functions, so understanding dynamics under climate change. These responses could be more robust in transitional zones such as the temperate-to-boreal forest ecotones, which are poised to experience substantial changes under …

Remnant assessment and soil inoculation to inform large-scale prairie restoration at Eastern Washington University
… characterized by rolling hills of deep loess soil, is one of the most endangered ecosystems in the world, with more than 99% converted to tilled farmland. To mitigate this loss, Eastern Washington University has begun prairie restoration on a tilled wheat field adjacent to campus, in the …

Soil Microbial Community Response to Human Decomposition in Michigan's Upper Peninsula
… (PMI) estimation. This study examines the soil microbiome associated with human decomposition at the Forensic Research Outdoor Station (FROST) in Marquette, Michigan – a unique taphonomy research facility characterized by cold temperatures, sandy soil, over 100 inches of snow annually, and …

Management, microbiology, and machine learning: A systems approach to evaluating the nitrogen cycling microbiome in agricultural soils
Soil microorganisms are integral to the regulation of Earth’s biogeochemical cycles. Within the nitrogen (N) cycle, the soil microbiome is responsible for a multitude of competing processes, some which lead to ecosystem N retention, and others to loss. Because they determine the fate of nitrogenous …

Disentangling Perceived and Measured Soil Health in New York City Urban Farms
Soil contamination is often addressed by constructing new compost-based soils for urban agriculture. We examined these constructed soils to assess soil health across a diversity of farming sites across New York City, consulting with farmers to characterize their soils as “healthy” or “unhealthy” …

Legume-rhizobia interactions in a complex microbiome
… and strain behaviour when exposed to a complex microbiome. To identify some these differences, this experiment applies two treatment factors in a controlled environment of containers with autoclaved sand. All main experimental containers were inoculated with several strains of Bradyrhizobia …

Plant-Soil Feedback and Perennial Forage Systems
Plant-soil feedback (PSF) is the process by which plants influence the survival and growth of other plants through effects on the soil and its biota. Understanding how PSF and management practices interact to influence native species persistence is critical for sustainable perennial forage systems. …

The BioLighthouse: Reusable Software Design for Bioinformatics
… making accessible a wealth of information about microbiomes. Unfortunately, microbiome experiments are among the least reproducible in terms of bioinformatics. Software tools are often poorly documented, under-maintained, and commonly have arcane dependencies requiring significant time investment …

Vineyard floor management in the Finger Lakes region: physiological and microbial perspectives
… quality. However, the standard practice of bare soil under vines exacerbates the vigor problem. Previous studies found that using under-vine cover crops reduced vine vigor in young vineyards but had little to no impact on mature vines. Wine sensory properties were impacted by under-vine cover …

Targeted short-term nutrient reduction to manage Ventenata dubia an invasive winter annual grass: soil and plant responses
… also reduce native plant diversity and harm the soil microbiome. These effects require additional measures to be taken, like reseeding, and plant diversity is still usually well below remnant targets. Early season short-term nutrient reduction to manage IWAGs is largely unexplored and would …

Interactions between cover crop residue and microbial community affect weed suppression
… inhibit weed germination, growth and production. Soil microbial communities are especially important for the allelochemical potential of a cover crop residue, because microorganisms can modify residues and allelochemicals to make them more or less phytotoxic. In addition to their effects on …

Patterns, Processes And Models Of Microbial Recovery In A Chronosequence Following Reforestation Of Reclaimed Mine Soils
Soil microbial communities mediate important ecological processes and play essential roles in biogeochemical cycling. Ecosystem disturbances such as surface mining significantly alter soil microbial communities, which could lead to changes or impairment of ecosystem functions. Reforestation …

The Impacts of Disruptive Environmental Change on Vital Microbial Ecosystems
… a forest fire to examine the impact of fire on soil microbial communities. We report drastic fire-induced shifts in bacterialcomposition post-fire, with a reduction in alpha- and beta-diversity and no significant recovery of the soil microbiome 1-year post-fire. We also show that certain …
