Chemical fertilizers, especially nitrogen (N) and phosphorus (P), are used in grasslands to
maximize plant biomass production for livestock. Despite a substantial body of work on how …

Purpose Global nitrogen deposition has profound impact on the terrestrial ecosystem
including the semiarid temperate grassland, causing vegetation community shifts and soil …

Ammonia oxidation in the soil is related to nitrogen (N) availability for plants, nitrate loss, and
N fertilizer use efficiency, which is important for studies on the N cycle of paddy field …

The effects of long-term fertilization of acidic soils on ammonia-oxidizing archaea (AOA) and
bacteria (AOB) communities and its ecological implications remain poorly understood. We …

With the increasing demands of livestock production, grasslands are under pressure from
over‐intensified grazing. Phosphorus (P) and nitrogen (N) fertilization is widely employed to …

As the first and rate-limiting step of nitrification, ammonia oxidation can be realized either by
ammonia-oxidizing bacteria (AOB) or archaea (AOA). However, the key factors driving the …

Archaeal (AOA) and bacterial (AOB) ammonia-oxidizer responses to long-term field
fertilization in a Mollisol soil were assessed through pyrosequencing of amoA genes. Long …

Ammonia-oxidizing microorganisms, ie ammonia-oxidizing bacteria (AOB) and ammonia-
oxidizing archaea (AOA), are the primary agents responsible for soil nitrification. Few …

Chronic nutrient addition to grassland soils can strongly influence the composition and
abundance of nitrifying microbial communities. Despite the fact that nitrifying microbes play a …

Long‐term field fertilization experiments may provide useful insight into the relative
contributions of NH3–oxidizing bacteria (AOB) and NH3–oxidizing archaea (AOA) to soil …
