Composting is a promising technology to decompose organic waste into humus-like high-
quality compost, which can be used as organic fertilizer. However, greenhouse gases (N 2 …

Nitrification, as a crucial step in nitrogen cycling and plant nutrition, is a biologically
mediated process responsible for enormous losses of nitrogen fertilizer and a contributor to …

Soil gross nitrification (GN) is a critical process in the global nitrogen (N) cycle that results in
the formation of nitrate through microbial oxidation of ammonium or organic N, and can both …

The continuous increase of the greenhouse gas nitrous oxide (N2O) in the atmosphere due
to increasing anthropogenic nitrogen input in agriculture has become a global concern. In …

Losses of nitrogen from the soil/plant system not only reduce soil fertility and plant yield but
can also create adverse impacts on the environment. Ammonia emissions into the …

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

Archaea, primarily Crenarchaeota, are common in soil; however, the structure of soil
archaeal communities and the factors regulating their diversity and abundance remain …

The recent discovery of complete ammonia oxidizers (comammox Nitrospira) challenged the
paradigm of the two-step nitrification mediated by two distinct groups of nitrifiers, and raised …

Genes of archaea encoding homologues of ammonia monooxygenases have been found
on a widespread basis and in large amounts in almost all terrestrial and marine …

Increasing evidence demonstrated the involvement of ammonia-oxidizing archaea (AOA) in
the global nitrogen cycle, but the relative contributions of AOA and ammonia-oxidizing …
