Aquifers constitute the only source of freshwater on PEI. In many areas, nitrate
concentrations in groundwater (GW) exceed natural levels. It is assumed that mineral …

The objective of this study is to estimate the soil N flux from the vadose zone to the aquifer of
the Wilmot watershed (Prince Edward Island, Canada) for a typical three-year cropping …

Agricultural activity, especially the application of fertilizers, is believed to be a major source
of nitrates in groundwater and surface water in Prince Edward Island. Analyses of 107 …

ABSTRACT A seasonal apportionment of nitrate sources has been conducted to investigate
the dynamics of nitrogen (N) transfer from soils to groundwater. A mass balance model is …

Stable isotopes of nitrate are used here to better understand the transfer of nitrogen (N) from
soils to groundwater (GW) in two agricultural settings of Prince Edward Island (PEI). Under …

Nitrate (NO3-) is one of the most widespread contaminants in freshwater systems globally.
This is largely due to high fertilizer application rates that are required to maximize crop yield …

This study aims to identify the possible roles of a floodplain inbiogeochemical nitrogen
cycles, based on analysis of groundwaterdynamics of inorganic nitrogen species …

La problématique du nitrate, principal contaminant azoté issu de la fertilisation, a été
identifiée dans de nombreux aquifères situés dans toutes les régions agricoles du monde …

Intensive farming usually imply a degradation of groundwater resources worldwide. In
particular, nitrate concentrations exceeding the 50 mg L− 1 limit established for drinking …

Summary 1 Nitrogen (N) loss from agricultural fields and urban areas to stream and
groundwaters is a world‐wide environmental problem. Excessive nitrogen loading is partly …
