Elevated temperature shifts soil N cycling from microbial immobilization to enhanced mineralization, nitrification and denitrification across global terrestrial ecosystems

Global Change Biology, 2020
We assessed the response of soil microbial nitrogen (N) cycling and associated functional genes to elevated temperature at the global scale. A meta‐analysis of 1,270 observations from 134 publications indicated that elevated temperature decreased soil ...

Comammox Nitrospira Species Dominate in an Efficient Partial Nitrification-Anammox Bioreactor for Treating Ammonium at Low Loadings.

Environmental Science and Technology, 2021
Bacteria capable of complete ammonia oxidation (comammox) are widespread and contribute to nitrification in wastewater treatment facilities. However, their roles in partial nitrification-anaerobic ammonium oxidation (anammox) systems remain unclear.

Global patterns and controlling factors of soil nitrification rate

Global Change Biology, 2020
Soil nitrification, an important pathway of nitrogen transformation in ecosystems, produces soil nitrate that influences net primary productivity, while the by‐product of nitrification, nitrous oxide, is a significant greenhouse gas.

Widespread Use of the Nitrification Inhibitor Nitrapyrin: Assessing Benefits and Costs to Agriculture, Ecosystems, and Environmental Health.

Environmental Science and Technology, 2021
Agricultural production and associated applications of nitrogen (N) fertilizers have increased dramatically in the last century, and current projections to 2050 show that demands will continue to increase as the human population grows.

Biological nitrification inhibition in the rhizosphere: determining interactions and impact on microbially mediated processes and potential applications.

FEMS Microbiology Reviews, 2020
Nitrification is the microbial conversion of reduced forms of nitrogen (N) to nitrate (NO3-), and in fertilized soils it can lead to substantial N losses via NO3- leaching or nitrous oxide (N2O) production. To limit such problems, synthetic nitrification

Nitrogen Mineralization, Immobilization, and Nitrification

SSSA Book Series, 2018
The biogeochemical cycling of N in ecosystems can be divided into an external and an internal N cycle. The external cycle includes those processes that add or remove N from ecosystems, such as: dinitrogen (N2) fixation, dry and wet N deposition, N ...

The Chemistry, Biology and Modulation of Ammonium Nitrification in Soil.

Angewandte Chemie, 2020
One to two percent of the world's energy is consumed for the production of ammonia from hydrogen and nitrogen gas. Ammonia is used as a fertilizer ingredient for agriculture and distributed in the environment on an enormous scale to promote crop growth ...

Plant influence on nitrification

Biochemical Society Transactions, 2011
Modern agriculture has promoted the development of high-nitrification systems that are susceptible to major losses of nitrogen through leaching of nitrate and gaseous emissions of nitrogen oxide (NO and N2O), contributing to global warming and depletion of the ozone layer.

Nitrification by soil fungi

Archiv f�r Mikrobiologie, 1960
1. Nitrifying fungi were isolated from soil and were found to belong to the genera Aspergillus and Penicillium. 2. While the Aspergillus-isolates produced both nitrite and nitrate, the penicillia were observed to produce only nitrate from nitrite.
