Irrigation Management

The plant pressure chamber is used to measure midday stem water potential as a means to assess the current tree water status.

Stem water potential readings give an integrated measure of water availability across the entire rootzone to the tree. This measurement can be considered equivalent to measuring blood pressure in humans.
