Valley Variable Rate Irrigation (VRI) Prescriptions

Valley® VRI Prescriptions

Customize Your Irrigation Application for Maximize Results


You have made the move to Valley® VRI, now what? The first thing you want to do is gather all the information and data on your field that you can possibly think of, then ask your Valley dealer or agronomist to write a VRI Prescription that is specific to your operation. A Prescription is really the cornerstone of VRI because it is the tool that tells your center pivot when and where to adjust the application depth in specific sectors or management zones in your field.

Your Prescription makes it easy to adapt to changes in soil moisture conditions and modify how you apply water to your management zones throughout the growing season. When you see a conditions change in part of your field, just change your VRI Prescription to vary water application in that specific zone! Customize your irrigation application to maximize not only results, but also profitability.

  • A VRI Prescription must be used with VRI Speed Control or VRI Zone Control to fully use either product

  • Allows the creation of a VRI plan based on your topography information, soil data maps, yield data, and other user-defined field information

  • Uploaded remotely to the control panel via Valley BaseStation2

  • For use on a consultant's or farmer's computer

There are three ways to create a VRI Prescription:

  1. Use the VRI Prescription Software, which is provided with VRI Speed Control and VRI Zone Control
