Quantifying the nitrogen cycle: from farm gate to catchments, groundwater and atmosphere

Nitrogen is fundamental to cotton growing and the industry needs to understand its full role, especially given that high N inputs to waterways can raise the risk of eutrophication in inland rivers. This longitudinal study analyses the irrigation sector’s impact on the nitrogen cycle, from the field to the atmosphere, surface waterways, and aquifers. It provides evidence that can be used to map the industry’s nitrogen cycle footprint in three selected river catchments.
