Researchers Develop Novel Approach for Quantifying Nitrate Discharge from Groundwater to Streams
Researchers Quantifying Nitrate Discharge Groundwater Streams
2016/11/29
Novel groundwater sampling (age, flux, and nitrate) carried out beneath a streambed and in wells was used to estimate (1) the current rate of change of nitrate storage, dSNO3/dt, in a contaminated unc...
Development of a Multivariate Regression Model for Soil Nitrate Nitrogen Content Prediction
linear regression multivariate statistics nitrogen NPS soil moisture spatial analysis visualization
2015/8/11
Although soil nitrate nitrogen (N) is a nutrient source for crop, it could be a potential nonpoint pollution source to the environment when its content remains high with an inappropriate management. S...
The importance of Dissimilatory Nitrate reduction to ammonium (DNra) in the Nitrogen cycle of coastal ecosystems
Dissimilatory Nitrate Nitrogen cycle
2015/7/16
Until recently, it was believed that biological assimilation and gaseous nitrogen (N) loss through denitrification were the two major fates of nitrate entering or produced within most coastal ecosyste...
Ethylene is involved in nitrate-dependent root growth and branching in Arabidopsis thaliana
Arabidopsis thaliana ethylene production lateral root development nitrate concentration nitrate transporters
2015/2/5
Here, we investigated the role of ethylene in high nitrate-induced change in root development in Arabidopsis thaliana using wild types and mutants defective in ethylene signaling (etr1, ein2) and nitr...
Nitric Oxide is Involved in Nitrate-induced Inhibition of Root Elongation in Zea mays
Nitrate supply nitric oxide (NO) IAA root elongation maize Zea mays
2015/2/5
Background and Aims Root growth and development are closely dependent upon nitrate supply in the growth medium. To unravel the mechanism underlying dependence of root growth on nitrate, an examination...

Managing soil nitrate with cover crops and buffer strips in Sicilian vineyards
Sicilian vineyards buffer strips
2015/1/5
When soil nitrate levels are low, plants suffer nitrogen (N) deficiency but when the levels are excessive, soil
nitrates can pollute surface and subsurface waters.

Dietary nitrate supplementation positively affects cardiovascular function at rest and energy metabolism during exercise in humans and has recently also been reported to markedly enhance the in vitro ...
Nitrate uptake by foraminifera and use in conjunction with endobionts under anoxic conditions
endobionts anoxic conditions
2014/11/28
Among eukaryotes, some benthic foraminiferal species have been reported to be capable of nitrate respiration,
although little is known about their denitrification processes. In this study, we incubat...
Sources and fate of nitrate in a groundwater-fed estuary elucidated using stable isotope ratios of nitrogen and oxygen
nitrate oxygen isotope
2014/10/16
We used d15N-nitrate (NO{
3 ) and d18O-NO{
3 to unravel the provenance and fate of NO{
3 in a groundwater-fed
estuary. A total of 13 monthly and two time series surveys were undertaken in the Werr...

Effect of Encapsulating Nitrate in Sesame Gum on In vitro Rumen Fermentation Parameters
Encapsulated Nitrate Sesame Gum Methane Rumen In vitro Fermentation
2016/5/17
Encapsulation is a method used to protect material from certain undesirable environments, for controlled release at a more favorable time and place. Animal productivity would be enhanced if feed addit...
Nitrogen fixation and dissimilatory nitrate reduction to ammonium (DNRA) support nitrogen dynamics in Texas estuaries
Nitrogen fi xation dissimilatory nitrate
2014/4/30
We conducted continuous-flow experiments on intact sediment cores from Laguna Madre, Sabine Lake, East
Matagorda Bay, and Nueces Estuary to evaluate internal nitrogen (N) sources, sinks, and re...
Nitrate–nitrite dynamics and phytoplankton growth: Formulation and experimental evaluation of a dynamic model
Nitrate–nitrite dynamics phytoplankton growth Formulation and experimental evaluation dynamic model
2014/4/4
A multi-nutrient quota model was modified to describe the coupled dynamics of nitrate and nitrite utilization for four phytoplankton species, Picochlorum atomus (Butcher) (Chlorophyta), Nannochloropsi...

Oxygen isotopic composition of nitrate nitrite produced nitrifying cocultures natural marine assemblages
2014/4/4
The δ18O value of nitrate produced during nitrification (δ18ONO3,nit) was measured in experiments designed to mimic oceanic conditions, involving cocultures of ammonia-oxidizing bacteria or ammonia-ox...
