Trying to understand the way Allowed Depletion works.
I have a zone setup with custom nozzles (based on measured flow rate and area) and the right settings for the area. I set Allowed Depletion to 20% and got the following info for Moisture levels:
I’ve update Allowed Depletion to 80% and looked at the graph again:
If I look at the data for Sep 18, I had (with 20% depletion) 0.66cm moisture balance, which is just above 100%. After changing to 80%, I now have moisture level at 1.3cm (double!) which is only 54%.
I understand that the entire calculation is based on the depletion point (the minimum amount becomes the new zero), but I can’t understand why field capacity (100%) changes? and why I suddenly have more water…
Would appreciate any insights.
