Two field days Aug. 27-28 will feature in-field demonstrations of soil water measuring tools designed to provide growers key data for irrigation management. Five of the systems were installed earlier this summer and users can view and compare data and displays online.
Final irrigations of the season are some of the most important water management decisions of the year. This guide walks through how to use weather and field information to schedule final irrigations and avoid costly, needless ones.
Center pivot sprinkler packages placed in the canopy have some potential to increase the application efficiency of center pivot and lateral move irrigation systems; however, the challenges of achieving acceptable water application uniformities and preventing local runoff are greatly increased. This is the third of a three-part series helping growers consider in-canopy vs. above-canopy sprinkler packages.
Center-pivot irrigation sprinkler package designs need to account for the specific pivot, the available water supply, and various attributes of the field where the pivot will be installed. Learn what to consider in this second article of a three-part series assessing in-canopy and above-canopy sprinklers and which is best for a given operation.
This is the first of a three-part series on how to decide whether you want to use in-canopy sprinklers or sprinklers at truss rod height or above on a center pivot. Part 1 addresses water losses from a center pivot and when to replace an existing sprinkler package.
Center pivot irrigation now accounts for approximately 85% of the irrigated land in Nebraska. To help growers manage and get the most from their system, Nebraska Extension has published the Center Pivot Irrigation Handbook, a 134-page comprehensive guide.
View corn variety plots and demonstrations of seven irrigation scheduling systems at the Aug. 31 Hamilton County Corn Growers Tour. The seven systems have been monitoring the same field throughout the season, providing a unique opportunity for growers to compare how each system manages similar information.
Take advantage of final crop irrigations this summer to evaluate system performance and identify leaks or problems to fix or aspects to improve over the winter. Taking time now can pay off in improved irrigation efficiency and reduced costs next season.
