Stand-replacing wildfires increase nitrification for decades in southwestern ponderosa pine forests. [PDF]
, 2014 Stand-replacing wildfires are a novel disturbance within ponderosa pine (Pinus ponderosa) forests of the southwestern United States, and they can convert forests to grasslands or shrublands for decades.

Estimating the effects of sea level rise on coupled estuarine nitrogen cycling processes through comparative network analysis [PDF]
Marine Ecology Progress Series 524: 137-154, 2013 Nitrogen (N) removal from estuaries is driven in part by sedimentary microbial processes. The processes of denitrification and anaerobic ammonium oxidation (anammox) remove N from estuaries by producing di-nitrogen gas, and each can be coupled to N recycling pathways such as nitrification and dissimilatory nitrate reduction to ammonium (DNRA ...

A modeling of the carbon-nitrogen cycle transport at Igapó I Lake - Londrina, Paraná, Brazil [PDF]
Acta Scientiarum. Technology, v. 34, n. 2, p. 217-226, Apr.-June,
2012, 2010 This work is a contribution to better understand the effect that domestic sewage discharges may cause in a water body, specifically Igap\'o I Lake, in Londrina, Paran\'a, Brazil. The simulation of the dynamics of pollutant concentrations all over the water body is conducted by means of structured discretization of the geometry of Igap\'o I Lake ...

Controls and Adaptive Management of Nitrification in Agricultural Soils
Frontiers in Microbiology, 2019 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 increase crop yields in most regions.

Effectiveness of Nitrification Inhibition on Various Species of Brachiaria Grass Rhizosphere
E3S Web of Conferences, 2018 Nitrification has the potential to decrease the efficiency of nitrogen utilization by plants. The use of nitrifying inhibitory chemicals proved to be effective in controlling nitrification, but also affects beneficial soil microbes.

Nitrate Deposition following an Astrophysical Ionizing Radiation [PDF]
Advances in Space Research 55, 2946-2949 (2015), 2014 It is known that a gamma ray burst (GRB) originating near the Earth could be devastating to life. The mechanism of ozone depletion and subsequent increased UVB exposure is the primary risk, but models also show increased nitrification culminating in nitric acid rainout.

Coupled anoxic nitrification/manganese reduction in marine sediments [PDF]
, 1999 Pore water and solid phase distributions of oxygen, manganese, and nitrogen from hemipelagic and shelf sediments sometimes indicate a close coupling between the manganese and nitrogen redox cycles.
