Nitrogen can help plants grow, but too much pollutes our rivers, lakes and groundwater. These resources can improve your understanding of how nitrogen flows through our environment, the drivers for regulation, and help you reduce nitrate leaching.

Denitrification in Shallow groundwaters – an ecosystem service or a pollution swap
Our observations highlight the influence of different hydrogeological settings on spatial variability of partial or complete (benign) denitrification in shallow groundwaters. A better understanding and…

Assessment of excess N2 for quantifying actual denitrification in NZ groundwater systems
Denitrification in groundwaters is a key nitrate (NO3) attenuation process, where leached NO3 can be reduced to gaseous forms of nitrogen (N2). In this study,…
