Something Similar to what you are talking about in another post “Even simpler than that, adding a frequency slider that will not make you understand MAD, root zone depth, field capacity, etc. Under the covers, I’m thinking we will just apply an offset to the crop coefficient, so you are effectively tracking towards more/less ET. That will magically make you water more/less frequent without having to change other values” How is Duration accounted for?
I reduced the allowable depletion from 50% to somewhere in the 30% range and did the same with the Efficiency slide as well. This kept my runtimes similar but increased the frequency. Instead of 4 to 5 days between watering I started seeing 2 to 3. There seem to be a lot of ETo’s in the .10 to .12 range on days it is 90 and the wind is blowing. Other controller is utilizing ETo numbers like .18-.22 which i feel is much closer to reality.
Take this week for instance, I am curious as to what your average ETo is across the Denver area and how does that compare to the numbers I am seeing in the moisture chart. My guess is it should be well above .11 ETo avg I am getting.
