Using Weekly Crop ET Reports in Young Developing Orchards

This tutorial consists of three shorter videos which combine for about 40 minutes of instruction. It focuses on making irrigation decisions in orchard crops during the early years of orchard establishment, as the trees grow from transplants to the early fruit bearing years. The videos provide instruction on how to adjust the weekly crop ET reports summarized in tutorial #1. Two different methods and step-by-step examples are given to demonstrate how to adjust the weekly crop ET reports to reflect young trees of various ages and sizes. We also address the question of how to adjust the timing and amount of irrigation using various pressurized irrigation methods with different amounts of orchard floor wetting.
