I want to make sure I understand the relevance of root depth for zones. It would seem to me that the greater the root depth the larger the amount of water to fill the “filed capacity” of the zone, correct? If I reduce my root depth by half, does the amount of water needed to fill up the moisture level get cut in half as well? My challenge is that while the IRO “knows” what nozzle types I have, it has no idea how many I have on each zone so it cannot know how much water is going onto the zone. I am thinking that gradually adjusting the root depth may be a simple way to get the watering times just right.
Does that make any sense?
