  • Assess conventional irrigation management using automated stem psychrometers
  • Monitor concurrent environmental conditions (esp. VPD)
  • Analyze and correlate cumulative water potential and vapour pressure deficit (VPD) integrals
  • Determine preliminary thresholds of plant water stress for irrigation management
