It would confuse things if I showed you mine right now. I have a bunch of new shrubs that are messing up what I would normally have. I will point out that my Available Water is 0.12 in/in and my Nozzle Inches Per Hour is 0.16in. Where did you get the numbers that you’re using?
The crop coefficient will depend on the tree type. Plants that need to be watered more will require a higher crop coefficient. For example, a Ficus would likely need a higher CC than a Mesquite.
Maybe, but keep your eye on the schedule and trees after the change. In my case what worked for me in the fall, winter & spring did not work in the summer. I ended up setting my crop coefficient based on the summer needs. I have Ficus trees and I think I was at ~80%.
That’s a pretty small change. I wouldn’t worry about that making too much of a difference.
This is where I got my Available Water number. It’s an important setting to get right before all of the other changes you’ll make. Setting this right overrides the Soil Type you have, and should be more accurate. I don’t think we have a lot of pure Loam in AZ.
Have you played around with this spreadsheet ? That’s how I set my numbers for drip.
