March Chapter Meeting
If you missed the March chapter meeting, you missed a fun one. Dr. Gerry Spinelli from the University of California Agriculture and Natural Resources (UCANR) gave a hands-on lecture about improving irrigation for fruit trees, complete with volunteers from the audience, pop quizzes by show of hands, and plenty of props passed around.
We learned about porosity of soil based on type, and why it matters when watering our trees. There was math (how much does your irrigation system supply in one hour) and we saw how evapotranspiration (EVT) numbers can help us calculate when to water next. We also explored how water pressure is affected by where on a hill your tree is, and why a pressure-compensating emitter might be a good idea.
Gerry’s presentation is available in the Members’ Area.
