Agricultural, urban and industrial activities have dramatically increased aquatic nitrogen and
phosphorus pollution (eutrophication), threatening water quality and biotic integrity from …

Nitrogen (N) is used in many of life's fundamental biomolecules, and it is also a participant in
environmental redox chemistry. Biogeochemical processes control the amount and form of N …

Nitrogen (N) and phosphorus (P) limitation constrains the magnitude of terrestrial carbon
uptake in response to elevated carbon dioxide and climate change. However, global maps …

There is global interest in understanding the prospects for biochar application to agricultural
soils. If biochar enhances the availability of nitrogen (N) and phosphorus (P) to crops, this …

Vanadium is a metal that receives increasing attention due to its possible toxicity and its
increased use in society, ie in high-grade steel and in vanadium redox-flow batteries …

Global nitrogen fixation contributes 413 Tg of reactive nitrogen (Nr) to terrestrial and marine
ecosystems annually of which anthropogenic activities are responsible for half, 210 Tg N …

Microbial interactions in soil are hidden, as they occur stealthily in a 'dark box'. This greatly
limits our understanding of microbial functions. Here, soil microorganisms were classified …

The soil microbial community fulfils various functions, such as nutrient cycling and carbon
(C) sequestration, therefore contributing to maintenance of soil fertility and mitigation of …

The biogeochemical cycles of carbon (C), nitrogen (N) and phosphorus (P) are interlinked
by primary production, respiration and decomposition in terrestrial ecosystems. It has been …

Free-living nitrogen fixation (FLNF) in the rhizosphere, or N fixation by heterotrophic bacteria
living on/near root surfaces, is ubiquitous and a significant source of N in some terrestrial …
