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 …

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 …

Background and aims Modern agriculture is driving the release of excessive amounts of
reactive nitrogen (N) from the soils to the environment, thereby threatening ecological …

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

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

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

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 …

Nitrogen (N) fertilization in agricultural soils is the largest anthropogenic source of nitrous
oxide (N 2 O) emissions, but the underlying mechanism of the varied response of N 2 O …

Soil acidification can be accelerated by intensive farming or prevented by sustainable
management practices. Soil acidification in a managed agricultural production system is …

Recent studies of ammonia-oxidizing archaea (AOA) suggested their significant
contributions to global nitrogen cycling, and phylogenetic analysis categorized AOA into a …
