Diverse crop rotations offset yield-scaled nitrogen losses via denitrification
Communications Earth & EnvironmentDenitrification, a major source of gaseous nitrogen emissions from agricultural soils, is influenced by management. Practices promoting belowground diversity are suggested to support sustainable agriculture, but how they modulate nitrogen losses via ...

Sedimentology, EarlyView.ABSTRACT Continental margins are reservoirs of materials of terrestrial and marine origin, and they play a crucial role in understanding the spatial and temporal variability of biogeochemical cycles. This, in turn, provides insights into the development and intensity of oxygen minimum zones (OMZs).

Factors Controlling Sediment Denitrification Rates in Grassland and Forest Streams
Terrestrial, Atmospheric and Oceanic Sciences, 2014 Sediment denitrification is an important nitrate (NO3-) removal process from agricultural streams. The direct and indirect factors that control denitrification rates in tributary sediments can vary depending on the types of agricultural activities and ...

Effect of agricultural practices on N2O emissions from Malagasy soils [PDF]
, 2007 Emissions of nitrous oxide (N20) are of concern because of the role of this gas in the greenhouse effect. The agricultural practices may affect the rate of N20 emissions from soil.

Water and Environment Journal, EarlyView.Tracer testing assessed hydraulics and nitrate removal in three full‐scale agricultural drainage treatment wetlands over 3.5 years (three tests). The first test showed rapid, short‐circuited flow and low residence time. After modifying the collection system, the second test increased residence time from 1 to 7 days.

The Role of Small Reservoirs in Reducing Reactive N Export Via Denitrification [PDF]
, 2019 Reactive nitrogen (N), which harms ecosystem health, has been increasing in the biosphere, leading to higher N export to coastal ecosystems. Although man-made reservoirs can be significant sources of greenhouse gases, they can also retain N, thus ...

Rapid Communications in Mass Spectrometry, Volume 40, Issue 14, 30 July 2026.ABSTRACT Rationale Pollution of surface and shallow groundwater by nitrate (NO3−$$ {\mathrm{NO}}_3^{-} $$) is a global concern, resulting in the deterioration of drinking water quality. Stable isotopes of NO3−$$ {\mathrm{NO}}_3^{-} $$ (δ15N and δ18O) can be used to trace its sources and identify prevailing biogeochemical processes.

Aquaculture, Fish and Fisheries, Volume 6, Issue 3, June 2026.ABSTRACT Aquaculture intensification is increasingly constrained by high water demand, nutrient‐rich effluents and disease risk, increasing interest in biofloc technology (BFT) as a waste‐recycling, low‐exchange production model. However, BFT performance depends strongly on the carbon source used to adjust the carbon‐to‐nitrogen (C/N) ratio and ...
