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 ...

Ammonia in Fly Ashes from Flue Gas Denitrification Process and its Impact on the Properties of Cement Composites

Buildings, 2019
The paper presents the results of research on the properties of fly ashes from the process of flue gas denitrification by selective non-catalytic reduction (SNCR), consisting of dosing urea into the coal combustion chamber.

Varying effects of stream restoration on riparian soil carbon persistence and methane emissions in the southern Rocky Mountains, United States

Restoration Ecology, EarlyView.
Abstract Introduction Channel incision can disconnect streams from their floodplains, potentially depleting carbon (C) in riparian soils by stimulating microbial decomposition. Stream restoration may offer an opportunity to replenish soil C pools by saturating riparian soils with water and slowing microbial activity.

Carbon availability mediates differences in rhizosphere denitrification potential between intercropped plants

Frontiers in Sustainable Food Systems
Denitrification is an important loss pathway for nitrogen (N) in agricultural systems; however, it is at times unpredictable. Some of the uncertainty surrounding denitrification rates is due to soil heterogeneity and spatial variability, especially with ...

Limited effects of structural restoration on ecosystem functioning in an urban tropical stream

Restoration Ecology, EarlyView.
Abstract Introduction Hydromorphological restoration through structural interventions is commonly used to mitigate urbanization impacts on lotic freshwater systems, but their effects on ecosystem functioning in urban tropical streams remain unexplored.

Nitrate attenuation in a restored river floodplain system: River Cole (Oxfordshire - UK)

, 2010
PhDRestoring river-floodplain connectivity has been proposed as an alternative management measure for natural flood defence through the temporary storage of floodwaters and the attenuation of flood peaks downstream.

Sedimentary biogeochemical provinces in the northern limit of the oxygen minimum zone from the northeastern Mexican Pacific

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).

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

, 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.

Effect evaluation of microplastics on activated sludge nitrification and denitrification

, 2020
A large amount of microplastics have entered conventional wastewater treatment plants, and their effects on activated sludge nitrification and denitrification are rarely reported.
