This tutorial consists of three videos. We explore how managed levels of crop stress can benefit some crops when employed properly by reducing risk of disease, aiding crop maturity, and optimizing water and energy inputs. We discuss how soil moisture deficits resulting from crop ET relate to tree water status. We provide brief instruction and examples on how to measure crop water status directly with a pressure chamber and interpret the field measurements. We suggest ways to use the weekly crop ET reports in tandem with the pressure chamber to increase your confidence in your irrigation decisions.
You can receive Irrigation & Nitrogen Management Plan Continuing Education Credits for watching these videos, but to do so you must access them through the CDFA INMP Credits, where you will also need to complete the post-video test.
