A novel aerobic-anoxic biological filter for nitrogen removal from UASB effluent using biogas compounds as electron donors for denitrification

Revista Facultad de Ingeniería Universidad de Antioquia, 2012
The performance of a new trickling filter (TF) configuration composed of an upper compartment for nitrification and a lower compartment for denitrification of effluent from a UASB reactor treating domestic sewage was evaluated.

Nitrate removal in a restored riparian groundwater system : functioning and importance of individual riparian zones [PDF]

, 2012
For the design and the assessment of river restoration projects, it is important to know to what extent the elimination of reactive nitrogen (N) can be improved in the riparian groundwater.

Evaluating Oxygen Demand in Mainstream Anammox, A2O and Partial Denitrification/Anammox (PD/A) Processes: A Gradient‐Based Sensitivity Analysis

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.

Nitric oxide and nitrous oxide production and cycling during dissimulatory nitrite reduction by Pseudomonas perfectomarina [PDF]

, 1989
The denitrifier Pseudomonas perfectomarina reduced nitrite under conditions of kinetic competition between cells and gas sparging for extracellular dissolved nitric and nitrous oxides, NOaq and N2Oaq, in a chemically defined marine medium.

Multistage and multiple biomass approaches to efficient biological nitrogen removal using biofilm cultures [PDF]

, 2008
Nitrogen removal from wastewater is important for the revention of significant health and environmental impacts such as eutrophication. Nitrogen removal is achieved by the combined action of nitrification and denitrification.

Knowledge gap on the spatial structure of soil nitrogen mineralization variability—A systematic review

Agricultural &Environmental Letters, Volume 11, Issue 2, December 2026.
Abstract Soil nitrogen (N) mineralization governs plant‐available N from soil organic matter and microbial turnover, and is typically estimated as potentially mineralizable nitrogen (PMN) via anaerobic incubations or as N0 and mineralization rate (k) via long‐term aerobic incubations.

Making gas diffusivity explicit in no‐till N2O interpretation

Agricultural &Environmental Letters, Volume 11, Issue 2, December 2026.
Abstract No‐till can conserve soil and store carbon, yet its effects on N2O emissions remain inconsistent. Soil gas diffusivity regulates O2 supply, N2O production and reduction, and the N2O/(N2O + N2) product ratio, but this control is not always explicit when no‐till outcomes are interpreted from surface fluxes alone.

Quantifying nitrogen release behavior of enhanced efficiency fertilizers in rainfed cotton through field‐based and combustion methods

Agricultural &Environmental Letters, Volume 11, Issue 2, December 2026.
Abstract The effectiveness of enhanced efficiency nitrogen fertilizers (EENFs) depends on how well the nitrogen (N) release synchronizes with crop demand. A 2‐year (2024–2025) mesh‐bag study was conducted to quantify N release from six N fertilizer sources under field conditions.

Electrolysis‐treated biosolids enhance wheat growth and alter soil health parameters

Agrosystems, Geosciences &Environment, Volume 9, Issue 4, December 2026.
Abstract Biosolid‐based fertilizers can benefit agriculture by supporting circular nutrient economies, reducing fertilizer costs, and minimizing environmental impacts compared to inorganic fertilizers. A 125‐day greenhouse experiment was conducted to assess the effects of electrolysis‐treated biosolids on wheat (Triticum aestivum) growth and soil ...

Diverse crop rotations offset yield-scaled nitrogen losses via denitrification

Communications Earth & Environment
Denitrification, 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 ...
