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...
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 heavy use of manure and fertilizers has in some parts of Sweden resulted in unacceptable concentrations of nitrate in ground water used for private and municipal water supply. In Halland for exa...
A nation-wide investigation of nitrate concentrations in groundwater in Denmark has been carried out. The investigation is based on analyses of groundwater samples from app. 11,000 wells and drinkin...
A conceptual model for simultaneous computation of runoff and inorganic nitrogen leaching is described. The model is semi-empirical with coefficients that are calibrated against observed data. It ha...
This paper presents a method that models the fraction of the NO, concentrations (nitrate and nitrite) in a marine recipient resulting from riverine runoff from land. The analysis is performed on the...
The City of Azul (Buenos Aires Province, Argentina), as many small cities in the country, is supplied entirely by local groundwater. Such waters contain variable, but generally high concentrations of ...
The closed chamber method was used to assess nitrous oxide (N2O) fluxes from corn (Zea mays, L.) fields during the 1995 growing season. The study area was characterized by a claypan soil overlying a n...
The functionality and pollution potential of the agroecosystem of the Los Jagüeles basin were characterized and an initial spatial assessment of nitrate levels in the phreatic aquifer was made. This a...
The objective of the present study was to construct electronic groundwater maps for the 60.5 ha dairy farm in the Teagasc Environment Research Centre at Johnstown Castle, Wexford, Ireland. Monitoring ...
To understand hydro-chemical characteristics of river water and NO3--N load toward Toyama bay through the base flow. The hydrological field survey and analysis of inorganic ion chemistry, stable isoto...
Three upland Lake District Tarns, Scoat, Greendale and Burnmoor, have been evaluated using MAGIC (Model of Acidification of Groundwater In Catchments) to reconstruct past, present and future chemical ...
The MERLIN model was applied on the results of a field-scale manipulation experiment with decreased nitrogen (N) deposition in an N saturated forest ecosystem in the Netherlands. The aim was to invest...
At a regional scale, high nitrate (NO3‾) concentrations in upland surface waters generally occur in tandem with high nitrogen (N) deposition levels. However, significant differences in the patte...
In this study, we evaluate the performance of the SWAT-N model, a modified version of the widely used SWAT version, for discharge and nitrate predictions at the mesoscale Dill catchment (Germany) for ...
