WHEAT NITROGEN FERTILIZATION UNDER NO TILL ON THE LOW ALTITUDE BRAZILIAN CERRADO
(Taylor & Francis Inc, 2014-01-01)
This study evaluates the effects of different nitrogen (N) rates (0, 50, 100, 150, and 200 kg ha(-1)) and sources (ammonium sulfate, urea, and ammonium sulfonitrate with a nitrification inhibitor, Entec (R)) applied either ...
Nitrogen maintenance requirements and potential for nitrogen retention of pullets in growth phase
(Wiley-Blackwell, 2019-07-01)
Experiments were conducted to estimate daily N maintenance requirements (NMRs) and the genetic potential for daily N retention (NRmaxT) of pullets in growth phase. Three nitrogen balance trials were conducted, and a total ...
Exchangeable basic cations and nitrogen distribution in soil as affected by crop residues and nitrogen
(Brazilian Archives of Biology and Technology, 2011-06-01)
In this work, a greenhouse experiment was conducted to study the effects of N fertilization and residues of pearl millet, black oats and oilseed radish on pH and Ca, Mg, K, NO3-, and NH4+ distribution within the profile ...

In this work, a greenhouse experiment was conducted to study the effects of N fertilization and residues of pearl millet, black oats and oilseed radish on pH and Ca, Mg, K, NO3-, and NH4+ distribution within the profile ...
Photo-Fenton approach for the determination of organic nitrogen in rainwater
(2018-10-01)
The importance of taking the organic forms of nitrogen (ON) into account when estimating atmospheric nitrogen deposition has been known for a long time. However, there is still only a modest amount of data on organic ...
Exchangeable basic cations and nitrogen distribution in soil as affected by crop residues and nitrogen

Experimental and bioinformatic approaches for analyzing and visualizing cyanobacterial nitrogen and hydrogen metabolism
(Pontificia Universidad Católica de Valparaíso, 2007)
Atmospheric concentrations and dry deposition of reactive nitrogen in the state of São Paulo, Brazil
(2020-06-01)
Estimates of nitrogen deposition play a key role in better understanding the human impacts on the nitrogen biogeochemical cycle. This paper examines the concentration of reactive nitrogen (Nr) in the atmosphere and the ...
Austenite instability and precipitation behavior of high nitrogen stainless steels
(Nova Science PublishersNew York, 2016)
Nitrogen is a strong austenite stabilizer and improves the mechanical properties and the corrosion resistance of austenitic stainless steels. For these reasons, nitrogen addition to steel has been extensively studied in ...
