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...
Nitrogen, Phosphorus and Carbon Dynamics during Storms in a Glaciated Third-Order Watershed in the US Midwest
DOC nitrate phosphorus hydrology
2015/1/16
The characterization of the nutrients nitrogen, phosphorus and carbon (NPC) export to streams during storms is an integral part of understanding processes affecting water quality. Despite the fact tha...

Modelling the inorganic nitrogen behaviour in a small Mediterranean forested catchment,Fuirosos (Catalonia)
inorganic nitrogen behaviour Mediterranean forested catchment Fuirosos
2010/3/5
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...
USE OF ISOTOPICALLY LABELED FERTILIZER TO TRACE NITROGEN FERTILIZER CONTRIBUTIONS TO SURFACE, SOIL, AND GROUND WATER
single N fertilizer ground water glacial aquifer
2009/10/13
The fate and transport of a single N fertilizer application through plants, soil, runoff, and the unsaturated and saturated zones was determined for four years at a field site under continuous corn (Z...
Nitrogen leaching from N limited forest ecosystems：the MERLIN model applied to Gårdsjön, Sweden
Nitrogen Sweden forest ecosystems
2009/6/5
Chronic deposition of inorganic nitrogen (N) compounds from the atmosphere to forested ecosystems can alter the status of a forest ecosystem from N-limited towards N-rich, which may cause, among other...
Integrated Nitrogen CAtchment model (INCA) applied to a tropical catchment in the Atlantic Forest, São Paulo, Brazil
Integrated Nitrogen in CAtchments atmospheric deposition rates hydrological conditions
2009/5/6
Stream-water flows and in-stream nitrate and ammonium concentrations in a small (36.7 ha) Atlantic Forest catchment were simulated using the Integrated Nitrogen in CAtchments (INCA) model version 1.9....
The role of catchment characteristics in determining surface water nitrogen in four upland regions in the UK
catchment characteristics upland regions surface water nitrogen
2009/5/6
Hydrochemical and catchment data from 80 upland moorland sites in four regions with contrasting climate, soils, geology and geomorphology have been analysed to assess the key catchment attributes that...
