Irrigate-IQ Variable Rate Irrigation

Every field is variable. They each vary in topography, soils, rainfall, and other factors. And because of this variability, not every area needs the same amount of water. Since too much or too little water can affect the quantity and quality of your yield, every decision you make about irrigation is critical.

With the Trimble® Irrigate-IQ™ precision irrigation solution, you can precisely apply the right amount of water, fertigation, or effluent in the right place—regardless of your pumping equipment. Choose between traditional variable rate irrigation (VRI) or optimal flow VRI, based on your equipment and needs, to optimize your water use and improve yields.

Traditional VRI

Irrigate-IQ™ traditional variable rate irrigation can be utilized by pivots with a variable frequency drive (VFD) or variable speed drive (VSD) pump. These pumps provide the right amount of flow and pressure to the pivot to account for varying application depths.

Optimal Flow VRI

Farmers who were unable to use VRI in the past, due to equipment constraints, can now apply the right amount in the right place. Irrigate-IQ™ optimal flow variable rate irrigation enables you to perform full VRI on pivot irrigation systems that have standard pump equipment or limited well capacity.

Irrigate-IQ variable rate irrigation is now available with Variable Rate Irrigation (VRI) products through both Trimble’s Vantage reseller network and the global Valley Irrigation dealer network. Now, more farmers worldwide can enhance their pivot’s capabilities by adopting a high-accuracy irrigation solution.


Irrigate-IQ variable rate irrigation works with center pivots from all major manufacturers and helps you:

  • Improve crop quality and yield
  • Optimize water use by reducing overwatering, underwatering, and run-off
  • Minimize input costs of water, fertigation or effluent
  • Reduce energy costs for fuel and electricity
  • Meet environmental regulations by controlling where and how much you irrigate

Individual Nozzle Control
Irrigate-IQ variable rate irrigation gives you control over each individual nozzle for the highest level of accuracy. Each nozzle is controlled independently, and its flow rate can be changed based on the irrigation plan and location.

Reliable Values
Industry-leading, 3-way vent to atmosphere valves ensure the system performs reliably all season. The rugged, fully-sealed housing prevents clogging and blockage, even when pumping unwanted debris. Plus, the valves default to the open position, so water will always flow, regardless of unexpected system events.

Flexible Options
The Irrigate-IQ solution is flexible and scalable to suit your irrigation needs. It can be installed on a many pivot makes and models that have basic or smart panels. You can start with a basic monitor and control system and upgrade to either optimal flow or variable rate irrigation at any time using the same base hardware. There is no loss of initial investment.
