Irrigation Scheduling: Do we really need to take a scientific approach?

摘要

AT FIRST thought the question above sounds like a dumb one. Of course we need to schedule irrigations — just like we schedule lunch; we get hungry, plants get thirsty. End of story. But how many of you skip lunch, or delay it? How often? If you're like some of us old agronomists who can't jump across the head ditch as easily as we used to and you look down and can't see as much of your feet as you did when you were 25, then you think, "Probably better if I skipped lunch anyway." Then you think on this idea even more and you say, "Well, I just ain't gonna eat anything until I see this gut disappear." But we all know this is bad idea as we still need balanced nutrition regularly even if we do have some extra weight.
