Using remote sensing to predict PI nitrogen uptake in rice locations
Aims

Four years of research have been conducted to determine if rice PIN uptake can be predicted using remote sensing from drones, aircraft and satellites as part of an ongoing Rural Industries Research & Development Corporation (RIRDC) research project. 

Key messages
  • Remote sensing can confidently be used to map a rice crop’s panicle initiation (PI) nitrogen (N) uptake.
  • A remotely sensed image of nitrogen uptake at PI can identify variability in the uptake and enable variable rate nitrogen topdressing to maximise grain yield with reduced risk.
  • Remotely sensed data has been collected using field spectroradiometer (SVC HR1024), multispectral cameras including the MicaSense RedEdge, Tetracam MCA and Headwall Hyperspectral Imager, and Worldview 3 satellite data.
