Oxidation of ammonia to nitrite by bacteria and archaea is responsible for global emissions
of nitrous oxide directly and indirectly through provision of nitrite and, after further oxidation …

Although the global nitrogen (N) cycle is largely driven by soil microbes, plant root exudates
can profoundly modify soil microbial communities and influence their N transformations. A …

Wetland soils are the greatest source of nitrous oxide (N2O), a critical greenhouse gas and
ozone depleter released by microbes. Yet, microbial players and processes underlying the …

Nitrification, the oxidation of ammonia to nitrate, is an essential process in the
biogeochemical nitrogen cycle. The first step of nitrification, ammonia oxidation, is performed …

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 …

Autotrophic archaeal and bacterial ammonia-oxidisers (AOA and AOB) drive soil nitrification.
Ammonia limitation, mixotrophy, and pH have been suggested as factors providing niche …

High and low rates of ammonium supply are believed to favour ammonia-oxidising bacteria
(AOB) and archaea (AOA), respectively. Although their contrasting affinities for ammonium …

Biochar has been suggested to improve acidic soils and to mitigate greenhouse gas
emissions. However, little has been done on the role of biochar in ameliorating acidified …

Nitrogen fertilisation of agricultural soil contributes significantly to emissions of the potent
greenhouse gas nitrous oxide (N2O), which is generated during denitrification and, in oxic …

Soil microorganisms play important roles in nitrogen cycling within forest ecosystems.
Current research has revealed that a wider variety of microorganisms, with unexpected …
