Effects of Temperature and Humidity on Soil Gross Nitrogen Transformation in a Typical Shrub Ecosystem in Yanshan Mountain and Hilly Region

Life, 2023
Shrubland is a pivotal terrestrial ecosystem in China. Soil nitrogen transformations play a crucial role in maintaining the productivity of this ecosystem, yet the driving forces underlying it have not been sufficiently addressed, particularly under ...

Coupling of carbon, nitrogen and oxygen cycles in sediments from a Mediterranean lagoon: a seasonal perspective [PDF]

, 2007
Experimental data and simulations were used to investigate the seasonal coupling between carbon, nitrogen and oxygen cycles in marine sediments from a eutrophic shallow lagoon in the Mediterranean Sea area.

Contingent Effects of Liming on N2O-Emissions Driven by Autotrophic Nitrification

Frontiers in Environmental Science, 2020
Liming acidic soils is often found to reduce their N2O emission due to lowered N2O/(N2O + N2) product ratio of denitrification. Some field experiments have shown the opposite effect, however, and the reason for this could be that liming stimulates ...

Repression of potential nitrification activities by matgrass sward species [PDF]

, 2010
Soil nitrification is a key process in regulating the relative availability of the various inorganic N forms to plants. In the current study, we investigated the effect of different plant species on numbers of ammoniaoxidizing microbial cells by ...

The nitrification process in soils and biological filters [PDF]

, 1933
SUMMARY. 1 An extensive review of the literature on nitrification shows that the workers in this subject may be divided into three groups, viz. (a the Winogradsky or purely autotrophic group, (b those who include growth in organic media, (c those who ...

Thermokinetics and gas emission characteristics of nitrification waste under different oxygen contents by using TG-FTIR technique

Case Studies in Thermal Engineering, 2023
Nitrification waste has been a main hazard factor in many fire and explosion accidents; however, its thermal characteristics, which provide critical information for hazard control, have not been extensively studied.

Changes in the Species and Functional Composition of Activated Sludge Communities Revealed Mechanisms of Partial Nitrification Established by Ultrasonication

Frontiers in Microbiology, 2022
To achieve energy-efficient shortcut nitrogen removal of wastewater in the future, selective elimination of nitrite-oxidizing bacteria (NOB) while enriching ammonia-oxidizing microorganisms is a crucial step. However, the underlying mechanisms of partial

High-throughput assays to identify archaea-targeting nitrification inhibitors

Frontiers in Plant Science
Nitrification is a microbial process that converts ammonia (NH3) to nitrite (NO2-) and then to nitrate (NO3-). The first and rate-limiting step in nitrification is ammonia oxidation, which is conducted by both bacteria and archaea.
