Optimize Those Last Few Irrigations

Scheduling the last few irrigations of the season deserves extra attention because the goal is not only to focus on keeping the crop wet enough to produce optimal yields, but also on using up stored soil water. Leaving the field a little drier at the end of the season will save irrigation costs, decrease leaching losses, improve soil conditions for harvest traffic, and save water for future years. Growers also don't want to miss out on capturing off-season precipitation.

Nebraska Water Facts

Nebraska means “flat water” from the Omaha Sioux “ni braska” and Oto “ni brathge”/ Nebraskier describing the Platte River. The Platte River was named by early French explorers, also meaning “flat.” The Panhandle is almost 6.5 times higher elevation than the Southeast. (5,424 ft above sea level versus 840 ft). Southeast NE receives 2.5 times as much annual precipitation as the Panhandle (average 33” versus 13”).
