Scheduling the Last Few Irrigations of the Season Deserves More of Your Management Time Than Earlier Irrigations

Nebraska Irrigation Center Pivot
Scheduling the last few irrigations of the season deserves more of your management time than earlier irrigations because one must not only focus on keeping the crop wet enough to produce optimal yields, but also on using up enough of the stored soil water to lower the level to 40% of plant available water in the top four feet.

With limited rainfall over most of the state this year and fairly extended hot, dry periods, many irrigators may be wondering when is the irrigation season going to end?  With the price of grain, it is also worth considering do I need to apply that last inch or two of water to get that last bushel or two?
