Interested in exploring what variable-rate irrigation might bring to your operation? Here's a look at what four major center-pivot manufacturers are offering:

T-L Irrigation

Variable-rate irrigation is available with T-L Irrigation center pivot management control systems. This enables growers to manage the water application by controlling the speed of the system, says Clark Bauer, the company's U.S. sales manager. T-L Irrigation has partnered with AgSense and CropMetrics to provide these products and services.

Using variable-rate application allows farmers to provide multiple water prescriptions within a field using a single center pivot. Variable-rate technology captures information about factors such as the terrain and soil and turns it into useable data. Prescriptions developed with CropMetrics Precision Irrigation Management Services can be put into practice using T-L’s remote-management product Precision Link and the Precision Point III (PPC III) Control Panel.

A new, one-time CropMetrics VRI Rx App Lifetime License is part of T-L’s variable-rate application offerings.

Valley Irrigation

Valley VRI features a combination of hardware and software allowing growers to adjust the desired amount of water in a sector (VRI Speed Control) or management zone (VRI Zone Control). Irrigation application can be programmed to match specific field conditions, including a variety of soil types and topography.


Cole Fredrick, VRI product manager for Valley Irrigation, says this technology is here to stay. Depending on how prescriptions are applied and the goal of the grower, he says, using this technology may increase total yields, optimizing the productivity of the management zones in the field. But Fredrick sees VRI helping growers not only maximize yields but also profitability.
