Stress detection with remote sensing
• Thermal data for water stress
• Optical data
– NDVI
• GreenSeeker & GreenSat, use of a well fertilized reference strip
– Red-edge based indices for chlorophyll status
– Fluorescence for rate of photosynthesis, RUE
– Photochemical reflectance index (PRI) for rate of
