The active functional microbes contribute differently to soil nitrification and denitrification potential under long-term fertilizer regimes in North-East China

Frontiers in Microbiology, 2022
Nitrogen (N) cycling microorganisms mediate soil nitrogen transformation processes, thereby affecting agricultural production and environment quality. However, it is not fully understood how active N-cycling microbial community in soil respond to long ...

Comparison of water availability effect on ammonia-oxidizing bacteria and archaea in microcosms of a Chilean semiarid soil

Frontiers in Microbiology, 2012
Water availability is the main limiting factor in arid soils; however few studies have examined the effects of drying and rewetting on nitrifiers from these environments.

Changes in the activities of key enzymes and the abundance of functional genes involved in nitrogen transformation in rice rhizosphere soil under different aerated conditions

Journal of Integrative Agriculture, 2023
Soil microorganisms play important roles in nitrogen transformation. The aim of this study was to characterize changes in the activity of nitrogen transformation enzymes and the abundance of nitrogen function genes in rhizosphere soil aerated using three

Effects of macrobenthic bioturbation on the abundance and community composition of ammonia-oxidizing prokaryotes under different temperatures

Journal of Freshwater Ecology, 2017
In order to investigate the effects of macrobenthos on the abundance and community composition of ammonia-oxidizing prokaryotes under different temperature conditions, laboratory microcosms containing two kinds of macrobenthos (Corbicula fluminea and ...

Occurrence and abundance of ammonia‐oxidizing archaea and bacteria from the surface to below the water table, in deep soil, and their contributions to nitrification

MicrobiologyOpen, 2017
Using molecular biology methods (qualitative and quantitative PCR), we determined the occurrence and abundance of ammonia‐oxidizing archaea (AOA) and ammonia‐oxidizing bacteria (AOB) from a dry inland soil in Basel, Switzerland, and from the riparian ...

Quantification of ammonia oxidation rates and the distribution of ammonia-oxidizing Archaea and Bacteria in marine sediment depth profiles from Catalina Island, California

Frontiers in Microbiology, 2012
Microbial communities present in marine sediments play a central role in nitrogen biogeochemistry at local to global scales. Along the oxidation-reduction gradients present in sediment profiles, multiple nitrogen cycling processes (such as nitrification,

Short‐term effects of Brassicaceae crop residue on soil nitrification and nodulation in the subsequent field pea

Agrosystems, Geosciences &Environment, Volume 9, Issue 4, December 2026.
Abstract Glucosinolates (GLS) in Brassicaceae crops are known to suppress soil nitrification. Despite widespread inclusion of Brassicaceae species in pulse crop rotations, their effects on soil nitrification and root nodulation of subsequent pulse crops are poorly understood.
