Pivot Efficiency Tips Part Two – Technology Ensures Peak Performance

You’ve checked your system and performed the necessary pre-season maintenance, but how will you know if it’s operating at peak efficiency? Lindsay Applications Engineer Steve Melvin has some suggestions.

Incorporate a Remote Monitoring and Control System

Because pressure is the single most important indicator of proper system function, it should be monitored frequently during the season. Incorporating FieldNET™ into your system will give you the ability to remotely monitor the pressure at the pivot point as well as at the out end of the pivot, sending an alert if there’s a problem.

With FieldNET you can also view and control your system from virtually anywhere. You can set auto-stops, control end guns, monitor soil moisture and more – resulting in less time in the field and less spent on valuable resources.

Replace Sprinkler Packages as Needed

The moving parts on sprinklers and pressure regulators wear out from time and use, so it’s recommended that sprinklers are replaced when the package is 8-10 years old, or has reached 10,000 hours of operation.

Use Variable Rate Irrigation (VRI)

Variable Rate Irrigation (VRI increases flexibility and provides more efficient use of resources – particularly on fields with areas that need more or less water than the average of the field. With Growsmart® by Lindsay Precision VRI, you can customize exactly the right amount of water or chemicals to each area of your field, giving you control over

Check Aerial Images

Look for patterns in the aerial images of your field. Circular patterns often are associated with sprinkler problems on the pivot. Aerial images also can reveal areas that are over watered or under watered – especially near sloped areas.

Finally, Melvin says water use efficiency can be improved by leaving higher levels of crop residue on the soil surface when it fits into the cropping system. The surface residue reduces evaporation and helps water from rain and irrigation infiltrate into the soil where it falls.
