Irrigation Water Management

Take the Guesswork Out of Irrigation

Stettler Supply Company’s Irrigation Water Management (IWM) Program uses real-time field data, crop demand, and system performance to deliver clear, accurate irrigation recommendations — helping growers irrigate with confidence and precision.

With IWM, you know:

  • How much water to apply
  • How long to run your system
  • Whether your irrigation system is performing effectively

No more fixed schedules. No more assumptions.

Just data-backed decisions designed to improve efficiency, crop performance, and water management.

How It Works

We combine three key components to create a complete irrigation strategy:

1. Soil Moisture Monitoring (Probe Data)

See exactly what is happening in your root zone with real-time soil moisture tracking.

2. Crop Water Use (ET Demand)

Irrigate based on actual crop demand using local weather and evapotranspiration (ET) data.

3. System Performance (DU & Efficiency)

Ensure your irrigation system is applying water evenly and efficiently across the field.


From Data to Decisions

We turn complex field data into simple, actionable recommendations, including:

  • Weekly irrigation plans tailored to your field
  • Run times calculated from your system specifications
  • Adjustments based on real-time soil moisture feedback
  • Insights into irrigation system performance and efficiency
