Ammonia oxidising archaea are among the most abundant living organisms on Earth and
key microbial players in the global nitrogen cycle. They carry out oxidation of ammonia to …

Agriculture is responsible for over half of the input of reactive nitrogen (N) to terrestrial
systems; however improving N availability remains the primary management technique to …

Highlights•Nitrification causes nitrogen losses with impact on crop yield and
environment.•Newly discovered microbes can be important for nitrification in agricultural …

The rhizosphere harbors complex microbial communities, whose dynamic associations are
considered critical for plant growth and health but remain poorly understood. We constructed …

Nitrification is the aerobic process of the nitrogen cycle that converts ammonia to nitrate and
is facilitated by ammonia-oxidizing and nitrite-oxidizing microorganisms. Ammonia-oxidizers …

Ammonia oxidation is a fundamental core process in the global biogeochemical nitrogen
cycle. Oxidation of ammonia (NH3) to nitrite (NO2−) is the first and rate-limiting step in …

Many wastewater treatment plants in the world do not remove reactive nitrogen from
wastewater prior to release into the environment. Excess reactive nitrogen not only has a …

Nitrous oxide (N2O) and nitric oxide (NO) are atmospheric trace gases that contribute to
climate change and affect stratospheric and ground-level ozone concentrations. Ammonia …

Microbes dominate terrestrial ecosystems via their great species diversity and vital
ecosystem functions, such as biogeochemical cycling and mycorrhizal symbiosis. Fungi and …

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 …
