Organic nitrogen is an important but yet not very well explored component of nitrogen deposition. In this study concentrations and fluxes of organic and inorganic nitrogen in bulk precipitation in an ...
Modelling the inorganic nitrogen behaviour in a small Mediterranean forested catchment,Fuirosos (Catalonia)
inorganic nitrogen behaviour Mediterranean forested catchment Fuirosos
2010/2/20
The aim of this work was to couple a nitrogen (N) sub-model to already existent hydrological lumped (LU4-N) and semi-distributed (LU4-R-N and SD4-R-N) conceptual models, to improve our understanding o...

Nitrogen Uptake by Cover Crops and Inorganic Nitrogen Dynamics in Andisol Paddy Rice Field
Cover crop Paddy field Nitrogen
2010/12/2
Paddy field rice can conserve N in the soil under flooded conditions. However, residual soil N represents a potential environment concern when fields are no longer flooded. Winter annual grass cover c...
Behavior of Inorganic Nitrogen in Tea Field Soils Heavily Applied with Nitrogen and Changes in Amino Acid Content of the First Crop Accompanying the Reduction of Nitrogen
Amino acid content Heavy application of nitrogen Inorganic nitrogen Soil solution Tea plants
2009/7/29
We investigated the behavior of nitrogen heavily applied to inter-row spaces of the fields and the deterioration in amino acid contents caused by the reduction in nitrogen. The concentrations of inor...
Effect of Legume Incorporation or Living Mulch on Rice Growth, Yield and Soil Inorganic Nitrogen in Southwest Japan
Cover crop White clover Rice Incorporation
2010/12/2
The effects of cover crop on rice growth, yield, and nitrogen in soil were investigated and compared with those of chemical fertilizer (CF) and no fertilizer (NF) application in the Shikoku region of ...
Modelling the ecosystem effects of nitrogen deposition：Model of Ecosystem Retention and Loss of Inorganic Nitrogen
nitrogen deposition Ecosystem Retention
2009/6/8
A catchment-scale mass-balance model of linked carbon and nitrogen cycling in ecosystems has been developed for simulating leaching losses of inorganic nitrogen. The model (MERLIN) considers linked bi...
THE EFFECT OF AGROTECHNICAL INTERVENTIONS ON SEASONAL CHANGES OF INORGANIC NITROGEN CONTENT IN THE SOIL
inorganic nitrogen nitrate nitrogen ammonium nitrogen
2010/12/8
We researched the influence of soil cultivation and fertilization on changes of nitrate, ammonium and inorganic nitrogen content in soil during the monitored vegetation periods (2004/2005 – 2005/2006)...
Nutrient concentrations and fluxes for podzolic and gley soils at Plynlimon, mid-Wales: implications for modelling inorganic nitrogen and phosphorus in upland UK environments
Plynlimon Hafren Hore streams nitrate ammonium
2009/3/17
The effect of felling on stream nitrate, ammonium and soluble reactive phosphate (SRP) concentrations is examined for acidic and acid sensitive Sitka Spruce afforested catchments with podzolic and gle...
Monitoring of inorganic nitrogen in surface and groundwater at the intensive farming villages of the Red River Delta, Viet Nam
Ammonium-N Chemical fertilizer Farming village Nitrate-N
2009/3/12
The quality of surface water (canal and pond water) and groundwater (well water) was monitored with an interval of 6 months from 2002 to 2005 at two farming villages near Ha Noi, Viet Nam. In the vill...
Dry and wet deposition of inorganic nitrogen compounds to a tropical pasture site（Rondônia, Brazil）
Dry and wet deposition inorganic nitrogen compounds tropical pasture site
2008/12/31
The input of nitrogen (N) to ecosystems has increased dramatically over the past decades. While total (wet + dry) N deposition has been extensively determined in temperate regions, only very few data ...

2014/4/21
The potentially toxic, diazotrophic filamentous cyanobacterium Cylindrospermopsis raciborskii has recently become a common component in the summer phytoplankton in the St. Johns River (SJR) estuary, F...
Nitrification and inorganic nitrogen distribution in a large perturbed river/estuarine system:the Pearl River Estuary,China
Nitrification inorganic nitrogen distribution river/estuarine system
2010/1/18
We investigated the spatial distribution and seasonal variation of dissolved inorganic nitrogen in a large perturbed estuary, the Pearl River Estuary, based on three cruises conducted in winter (Janua...
