PSY1 Psychrometer for Plant Water Potential
Measuring plant water potential, the ICT International Psychrometer is a unique, non-destructive, and continuous in-situ logging device.
Plant water potential measurement has traditionally been undertaken using a pressure chamber (also known as a pressure bomb) that requires a cutting or sample from the plant for a one-off measurement.
Irrigation scheduling and plant water requirement determinations require the measurement of plant water potential, the energy that the plant exert when extracting water from the soil. The measurement is also important for selecting plant species for drought tolerance.
The ICT International Psychrometer is available with a chamber for the measurement of plant water potential of the stem or leaf:
- PSY1 Stem Psychrometer.
- PSY1 Leaf Psychrometer.
