Developing A Nursery Irrigation Regime

July 29, 2014 2:13 pm

Tree Selection with PSY1 Stem Psychrometer

The PSY1 Stem Psychrometer is used to continuously monitor plant water potential. Not only is the PSY1 improving our scientific understanding of plant physiology but it is also addressing the practical need of efficient irrigation management.

Professor Mike Dixon, from University of Guelph, Canada, recently examined how the PSY1 Stem Psychrometer could be used to determine whether a mychorrhizal association improved plant hydration in potted trees and whether the instrument could also be used to develop an irrigation regime. Specifically, the study aims were:

  • To test claims a mychorrhizal soil amendment can reduce water stress of ornamental nursery grown trees.
  • Develop a plant water stress monitoring protocol by continuously monitoring plant water potential (Ψ) to better manage water requirements of nursery grown ornamental trees during transplanting , to avoid over watering and under watering during a significant, induced stress and achieve better survival rates of transplanted trees.
