Comparison of different strategies for nitrogen removal by simultaneous nitrification and denitrification process in a batch rotating disk reactor
(Natural State Research, Inc., 2017-10)
In this paper, different strategies of aeration and organics feed in the reactor were studied toevaluate the simultaneous nitrification and denitrification (SND) process efficiency for a sequencing batchrotating disk biofilm ...
Resilience of nitrification process in agricultural and restored soils of central Argentina
(Global Institute for Research & Education, 2013-07)
The aim of this study was to assess the resilience degree of soil nitrification process (by nitrate content, nitrification rate, and nitrifier abundance measurements), in soils of central Argentina. Soil nitrification ...
Ammonia volatilization losses from surface-applied urea with urease and nitrification inhibitors
(2012-09-01)
Urease inhibitor (UI) and nitrification inhibitor (NI) have the potential to improve N-use efficiency of applied urea and minimize N losses via gaseous emissions of ammonia (NH 3) to the atmosphere and nitrate (NO3-) ...
Mitigation of N2O emissions from grassland by nitrification inhibitor and actilith F2 applied with fertilizer and cattle slurry
(2002-06-24)
Nitrous oxide (N2O) is involved in both ozone destruction and global warming. In agricultural soils it is produced by nitrification and denitrification mainly after fertilization. Nitrification inhibitors have been proposed ...
Nitrogen Mineralization and Nitrification in Two Soils with Different pH Levels
(2019-12-16)
Soil pH is one of the properties that mostly influences nitrification rates, and can be used as a tool for controlling this process, seen that depending on its extent it may lead to nitrogen (N) losses and subsequent ...
Respirometric techniques for assessment of biological kinetics in constructed wetland
(I W A Publishing, 2007-01-01)
The aim of this research was the development of a procedure to measure biological kinetics of organic matter oxidation and nitrification in constructed wetland, by using respirometric techniques. Columns simulating cores ...
Nitrification inhibition in tropical soil under no tillage system
(2014)
In no-tillage systems (NTS), biological activity and nitrification process in the soil are higher due to higher organic matter and moisture contents, resulting in higher levels of nitrate compared with areas under conventional ...
Elevation and vegetation influences on soil properties in Chilean Nothofagus forests
(Sociedad de Biología de Chile, 2003)
Nitrification and ammonia-oxidizing bacteria shift in response to soil moisture and plant litter quality in arid soils from the Patagonian Monte
(Elsevier Gmbh, 2016-01)
We aimed to evaluate the effects of both plant litter quality, characteristic of sites with different histories of grazing disturbance, and soil water content on nitrification in soils from an arid ecosystem of Patagonia. ...
Inibição da mineralização de compostos nitrogenados de lixiviado de macrófita aquática: Adequação metodológica
(2008-04-01)
This study aimed to establish the adequate concentrations of nitrapyrin for the effective inhibition of oxygen demand required for the oxidation of nitrogen compounds during aerobic mineralization of leachate. The aquatic ...
