How to Find and Read the Infiltration Map
The Infiltration Map is located directly below the Soil Moisture (AWC) chart on a probe page.
It uses the same soil moisture data as the AWC chart but displays it as a cross-section of the soil profile over time. This makes it easier to see how water moves through the soil and where roots are actively using moisture.
Understanding the Infiltration Map
The top of the map represents the shallowest sensor and the bottom represents the deepest sensor.
The colors indicate soil moisture conditions:
Color | Meaning |
Blue | Soil is too wet |
Green | Ideal soil moisture |
Yellow | Moderate water deficit |
Red | Severe water deficit |
A small amount of yellow or red near the surface is normal, as shallow soils dry out more quickly.
What are the blue icicles?
The blue "icicles" represent irrigation or rainfall events and show how deeply water infiltrated into the soil profile.
Use these patterns to determine whether water is reaching the active root zone or moving deeper than necessary.
How can I use the Infiltration Map?
The Infiltration Map helps you:
Visualize how water moves through the soil profile.
See how deeply irrigation and rainfall events infiltrate.
Identify the active root zone by observing where moisture changes occur most frequently.
Determine whether irrigation is reaching the desired depth.
Identify areas that may be staying too wet or becoming water stressed.
In general, irrigation should target the active root zone. Water moving significantly below the active root zone may be less available to the plant and can reduce irrigation efficiency.
