PLANTS, PEOPLE, PLANET, EarlyView.Demand for agricultural land has increased due to rising demand for food, potentially leading to expansion into previously untouched habitats, which threatens refugia of native plants. We aimed to provide insight into how variation in seeding ratio may impact soil bacterial communities in a pea‐canola intercropping system, potentially altering crop ...

Dinitrogen fixation and nitrogen transfer among red clover cultivars
, 1993 Red clover (Trifolium pratense L.) is an important perennial forage legume used for hay or as pasture in crop rotations. Despite its traditional usage as a source of nitrogen (N) for cropping systems, little information is available on the amounts of ...

A quantitative model of nitrogen fixation in the presence of ammonium.
PLoS ONE, 2018 Nitrogen fixation provides bioavailable nitrogen, supporting global ecosystems and influencing global cycles of other elements. It provides an additional source of nitrogen to organisms at a cost of lower growth efficiency, largely due to respiratory ...

Water and Environment Journal, EarlyView.This graphical abstract illustrates the oxygen demand reduction potential of the mainstream anammox process compared to conventional A2O and PD/A processes. It visually demonstrates maximum oxygen savings of 28.25% and 18.58%, respectively, under optimal conditions.

Frontiers in Marine Science, 2022 The apparently obligate symbiosis between the diazotroph Candidatus Atelocyanobacterium thalassa (UCYN-A) and its haptophyte host, Braarudosphaera bigelowii, has recently been found to fix dinitrogen (N2) in polar waters at rates (per cell) comparable to

Distribution and rates of nitrogen fixation in the western tropical South Pacific Ocean constrained by nitrogen isotope budgets [PDF]
Biogeosciences, 2018 Constraining the rates and spatial distribution of dinitrogen (N2) fixation fluxes to the ocean informs our understanding of the environmental sensitivities of N2 fixation as well as the timescale over which the fluxes of nitrogen (N) to and from the ...

Journal of Environmental Quality, Volume 55, Issue 6, November/December 2026.Abstract Dense beds of floating macrophytes can alter water quality by modifying dissolved oxygen (DO) and nitrogen (N) dynamics. Water chestnut (Trapa natans L.), a non‐native annual macrophyte, forms extensive seasonal beds in freshwater systems in North America. The species is intensively managed to reduce negative impacts on native species, yet its

Land Degradation &Development, Volume 37, Issue 17, Page 12392-12405, November 2026.ABSTRACT Optimized fertilization involving reduced mineral N input and organic substitution can alter resource stoichiometry, microbial carbon use efficiency (CUE) and nitrogen use efficiency (NUE). However, how fertilization‐induced resource imbalance reshapes microbial community to regulate CUE and NUE remains unclear. We conducted a field experiment
