Irrigation Part 6: The Pressure Chamber and Start of Irrigation in Walnut with Shackel and Fulton

Summary: The pressure chamber is the gold standard for measuring plant water status. Ken Shackel (UC Davis Plant Sciences) discusses why using the pressure chamber can hugely refine your irrigation management. Allan Fulton (UCCE Irrigation Advisor) tells us about research in walnut showing that delaying irrigation with the pressure chamber can save water and may improve root health without sacrificing yield.
