Irrigation Calculator

This calculator uses evapotranspiration (ET) data combined with crop-specific coefficients to determine water requirements. Different crops, growth stages, and climate conditions all affect how much water your fields need.

1. 1

   Step 1

   Enter the total field area in acres

2. 2

   Step 2

   Select your crop type from the dropdown

3. 3

   Step 3

   Choose the current climate conditions

4. 4

   Step 4

   Select the crop's current growth stage

5. 5

   Step 5

   Review water requirements in gallons, liters, and acre-feet

• 1

  Corn needs about 25 inches of water throughout the growing season

• 2

  Drip irrigation can reduce water use by 30-50% compared to flood irrigation

• 3

  Morning irrigation reduces evaporation losses

• 4

  Flowering stage is critical - water stress during this time severely impacts yields

• 5

  Soil moisture sensors can help optimize irrigation timing

• Over-irrigating which wastes water and can cause root diseases

• Under-watering during critical growth stages

• Not accounting for recent rainfall when scheduling irrigation

• Ignoring soil type differences in water retention
