Using the Pressure Chamber for Irrigation Management in Walnut, Almond and Prune

Abstract

This publication describes how a pressure chamber is used to measure midday stem water potential (SWP) and how that information is used to guide irrigation scheduling decisions for walnut, almond, and prune. When used correctly, the pressure chamber can help growers and consultants save water, reduce irrigation costs, improve growth in developing orchards, and sustain higher levels of crop productivity while reducing tree loss and increasing orchard life span.
