Center pivot irrigating late-season corn

Scheduling the Last Irrigations in a Year with Delayed Crop Maturity

August 23, 2019
The last few irrigations of the season require some of the most important water management decisions of the year. An unneeded irrigation may waste 1 to 3 inches of water and 2 to 5 gallons of diesel fuel per acre and leave little room in the soil profile to capture winter/spring rains.

Figure 1. Fuel gauges help us determine how long until we need to put fuel in the tank and how much it will hold. Wouldn’t it be nice to have a gauge on your crop to tell you when to irrigate? Learn more about how soil water monitoring equipment can provide you similar information at two workshops on June 19 in Aurora and June 25 in York.

Workshops Focus on Irrigation Scheduling to Save Money, Water Even in Wet Years

Management Recommendations for Irrigation Equipment Affected by Flooding

March 25, 2019
As waters drain and soils dry out, part of the recovery process will include checking irrigation systems for damage and performing maintenance/repair before those systems can be used. Here's what to check in your power unit, irrigation well, and center pivot.

Soil water measuring guage.
Wouldn’t it be great if our crops had a soil water gauge on them like the fuel tank? We could use them to help us directly determine when we need to irrigate and how much water the soil will hold. Soil water monitoring equipment can be the next best thing.

Field Days to Feature Irrigation Scheduling Equipment Demos

August 16, 2018
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.

In-canopy center pivot sprinkler head entangled in the corn canopy

In-Canopy vs. Above-Canopy Sprinklers: Consider Pros and Cons

April 5, 2018
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.
