Evaluation of the stable isotope signatures of nitrate to detect denitrification in a shallow groundwater system in New Zealand
(Elsevier B.V., 2015-04-01)
Denitrification in the groundwater systems of agricultural catchments can provide a substantial ‘ecosystem service’ by attenuating leached nitrate (NO₃⁻) before it reaches surface water bodies. Samples along a groundwater ...
Ammonia volatilisation is not the dominant factor in determining the soil nitrate isotopic composition of pasture systems
(Elsevier B.V., 2015-01-01)
© 2014 Elsevier B.V. Nitrate dual isotopes (δ¹⁵N-NO₃⁻ and δ¹⁸O-NO₃⁻) are increasingly used to assess the sources and sinks of nitrogen (N) pollution in freshwater systems. However, the application of this methodology to ...
