The HyperNUE (Nitrogen Use Efficiency) project is transforming how crops are monitored, using advanced remote sensing to measure nitrogen use and photosynthesis at scale. A collaboration between ANU, the University of Sydney, the University of Lincoln (UK), and RAL Space STFC (UK), it is redefining how crops are monitored through expertise in plant science and space technology.

Traditionally, assessing nitrogen required time-consuming lab tests. Building on decades of research by Professor Robert Furbank, HyperNUE applies hyperspectral imaging, the analysis of light reflected from leaves, to estimate nitrogen levels and photosynthetic activity without harming plants.

The project takes this breakthrough beyond single leaves, deploying clip-on sensors, drones, robots, and satellites to monitor entire crops. This could potentially give farmers the ability to track nutrition and crop health in real time, from paddock to regional scale.

By uniting global expertise, HyperNUE demonstrates how science and technology can improve yields, reduce fertiliser waste, and strengthen food security in the face of climate change.
