Reviews and syntheses: The promise of big diverse soil data, moving current practices towards future potential Open
In the age of big data, soil data are more available and richer than ever, but – outside of a few large soil survey resources – they remain largely unusable for informing soil management and understanding Earth system processes beyond the …

Variation in Bacterial Community Structure Under Long-Term Fertilization, Tillage, and Cover Cropping in Continuous Cotton Production Open
Agricultural practices alter the structure and functions of soil microbial community. However, few studies have documented the alterations of bacterial communities in soils under long-term conservation management practices for continuous c…

Permafrost Active Layer Microbes From Ny Ålesund, Svalbard (79°N) Show Autotrophic and Heterotrophic Metabolisms With Diverse Carbon-Degrading Enzymes Open
The active layer of permafrost in Ny Ålesund, Svalbard (79°N) around the Bayelva River in the Leirhaugen glacier moraine is measured as a small net carbon sink at the brink of becoming a carbon source. In many permafrost-dominating ecosyst…

Effect of Residue Type on Extractable Organic and Microbial Biomass Carbon Fractions Under Long-Term Soil Fertilization Open
The labile organic carbon (C) pool plays a vital role in soil biogeochemical transformation and can be used as a sensitive indicator of the response of soil quality to agricultural practice. However, little is known about how residue type …

Soil Health Management Enhances Microbial Nitrogen Cycling Capacity and Activity Open
Conservation agriculture practices that promote soil health have distinct and lasting effects on microbial populations involved with soil nitrogen (N) cycling. In particular, using a leguminous winter cover crop (hairy vetch) promoted the …

Effects of field-grown transgenic switchgrass carbon inputs on soil organic carbon cycling Open
Genetic engineering has been used to decrease the lignin content and to change the lignin composition of switchgrass ( Panicum virgatum L.) to decrease cell wall recalcitrance to enable more efficient cellulosic biofuel production. Previou…

Viral and bacterial community responses to stimulated Fe(III)‐bioreduction during simulated subsurface bioremediation Open
Summary The delivery of fermentable substrate(s) to subsurface environments stimulates Fe(III)‐bioreduction and achieves detoxification of organic/inorganic contaminants. Although, much research has been conducted on the microbiology of su…
