Nitrite (NO2−) is an intermediate in a variety of soil N cycling processes. However, NO2− dynamics are often not included in studies that explore the N cycle in soil. Within the presented study, nitrite dynamics were investigated in a Nothofagus betuloides forest on an Andisol in southern Chile. We carried out a 15N tracing study with six 15N labeling treatments, including combinations of NO3−, NH4+ and NO2−. Gross N transformation rates were quantified with a 15N tracing model in combination… Expand
Assessment of the importance of dissimilatory nitrate reduction to ammonium for the terrestrial nitrogen cycle
Abstract. The nitrogen (N) cycle contains two different processes of dissimilatory nitrate (NO3−) reduction, denitrification and dissimilatory NO3− reduction to ammonium (DNRA). While there isExpand
Gross Nitrogen Dynamics in the Mycorrhizosphere of an Organic Forest Soil
The rhizosphere is a hot-spot for biogeochemical cycles, including production of greenhouse gases, as microbial activity is stimulated by rhizodeposits released by roots and mycorrhizae. TheExpand
Analysis of the coexisting pathways for NO and N2O formation in Chernozem using the 15N-tracer SimKIM-Advanced model
TLDR
This analysis model explains the observed differences in the 15N enrichments in nitric oxide (NO) and nitrous oxide (N2O) which occurred in dependence on different oxygen concentrations, highlighting the necessity of individual soil-dependent parameter estimations. Expand
Heterotrophic nitrification is the predominant NO3− production mechanism in coniferous but not broad-leaf acid forest soil in subtropical China
A study was carried out to investigate the potential gross nitrogen (N) transformations in natural secondary coniferous and evergreen broad-leaf forest soils in subtropical China. The simultaneouslyExpand
Dissimilatory nitrate reduction to ammonium (DNRA) plays an important role in soil nitrogen conservation in neutral and alkaline but not acidic rice soil
PurposeIn the rice soils, the alternate wetting and drying conditions and the leakage of O2 from rice roots provides a favorable environment for many N transformation processes, such as DNRA,Expand
Production and consumption of N2O during denitrification in subtropical soils of China
PurposeNitrous oxide (N2O) production and reduction rates are dependent on the interactions with each other and it is therefore important to evaluate them within the context of simultaneouslyExpand
Denitrification and dissimilatory nitrate reduction to ammonium (DNRA) in a temperate re-connected floodplain.
TLDR
The results indicate that bacteria capable of DNRA do survive in frequently flooded riparian zones, and to a limited extent, compete with denitrification for nitrate, acting to retain and recycle nitrogen in the floodplain. Expand
Pathways for Nitrous Oxide Generation in Forested and Agricultural Zones Growing on Volcanic Ash Soils
We studied the in situ relative contribution of soil nitrous oxide (N 2 O) emissions from already discovered pathways, namely the nitrification, nitrifier denitrification (ND), and heterotrophicExpand
Dissimilatory nitrate reduction to ammonium and N2O flux: effect of soil redox potential and N fertilization in loblolly pine forests
Nitrogen (N) fertilization and soil redox potential influence N cycling processes in forested ecosystems. Gross N transformations are indicators of NH4+ and NO3− production and consumption withinExpand
Dissimilatory nitrate reduction to ammonium (DNRA), not denitrification dominates nitrate reduction in subtropical pasture soils upon rewetting
Abstract Soils under pasture are subjected to repeated wetting and drying cycles in response to rainfall, irrigation and evapotranspiration. The amplitude of these cycles is likely to increase underExpand

TLDR
High N mineralization rates in unpolluted, old-growth forests in the coastal range of southern Chile are suggested to be a consequence of enhanced atmospheric N deposition, implying the existence of strong sinks for NO3− in the ecosystem. Expand
