Tracer Test as a Tool for Optimizing the Flow Patterns and Efficiency of a Full‐Scale Drainage Water Treatment Wetland

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.

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

, 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.

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 ...

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.

Direct uptake of electrode electrons for autotrophic denitrification by Thiobacillus denitrificans

, 2015
In this work, we reported that Thiobacillus denitrificans could utilize poised electrodes directly as sole electron donors for autotrophic denitrification in bioelectrochemical systems.

Tillage does not impact soil greenhouse gas emissions in a Central Texas rainfed maize–cotton system

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Agricultural soils are a significant source of greenhouse gas (GHG) emissions, primarily as N2O. Monitoring how management practices impact soil gas fluxes (CO2, CH4, and N2O) is useful for making sure conservation practices (e.g., no‐till) are sustainable with regards to all potential environmental impacts.

Aerobic denitrification in permeable Wadden Sea sediments

, 2010
Permeable or sandy sediments cover the majority of the seafloor on continental shelves worldwide, but little is known about their role in the coastal nitrogen cycle. We investigated the rates and controls of nitrogen loss at a sand flat (Janssand) in the
