Nebraska Corn, Soybeans: Scheduling the Last Irrigations of the Season

Photo: Lyndon Kelley, Michigan State University 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.
Scheduling the Last Few Irrigations of the Season Deserves More of Your Management Time Than Earlier Irrigations
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. This level will give about 2.4 inches of water storage room in sandy soils and about 5.5 inches in silt loam soils.
Connect to a Private Instance Using a Bastion Host Within a Custom VPC
- Use Case You are a cloud engineer tasked with setting up the security and network architecture for your organization’s environment. For extra security you have a server that needs to be in a private subnet and should only be accessible through a Bastion Host.

What to do with irrigation equipment affected by flooding
PLACES TO CHECK: On center pivots, the main components to check are the wheel and center drive gearboxes, center drive motors on electric drive pivots, tower boxes if the water reached them, and the pivot panel. Part of the recovery process includes checking systems for damage and performing maintenance and repair.

A checklist for winterizing your center pivot
By Troy Ingram With irrigation season wrapped up, now is a good time to evaluate your center pivot to make sure it is ready for winter and for another growing season. Here is a quick list of things to look at before winter sets in: Flushing the system • Flush the system if you have water quality issues or if your well is pumping sand. • Clean out the sand trap. • Drain water from all aboveground pipe. Panel boxes • Check for loose or damaged connections.

How to calculate crop water use
By Troy Ingram Do you know how much water your crop is using on a daily basis? When I ask this question, most growers tell me somewhere between 0.20 and 0.40 inch per day. Sometimes they are close, but wouldn't it be nice to know for sure? It is rather simple to figure out if you have the right tools. An atmometer, such as the ETgage, is what you need to calculate reference ET, or evapotranspiration.
Using the Crop Water App With Watermark Sensors
The Crop Water App developed by Nebraska Extension is an excellent tool for producers using Watermark soil moisture sensors to aid irrigation scheduling. Here is a brief overview of how to use this app (Figure 1) in your operation. After downloading and opening the app, enter the field name you are currently working in. Then tap the arrow on the screen and the app will use the device’s GPS to input the coordinates of the sensors in the field (Figure 2).
