Golf Course Water Management - Soil Moisture Levels
New moisture sensor technology is helping understand what is going on underneath the surface. And that means wecan make better decisions about turf grass stress and our ability to optimize irrigation.
It’s an exciting area of new research, when understanding what’s going on under the soil can be integrated to weather forecasting and turf health prediction models to alleviate plant stress before it occurs, and make far more efficient use of water resources.
Hand held probes are a great first step, but are time consuming. Permanently imbedded probes keep a constant watch, but the wiring has previously been a limitation.

Now, remote sensors, either on a wireless system or with their own transmitters, offer the chance to precisely tailor water requirements.
Probes do need to be set to give a representative reading for any range of greens being managed, and that the measure is at the appropriate depth for where roots are being encouraged to grow.
Then calibrated to understand what the reading means in terms of turf health and when wilting points will be hit.
To calibrate a soil moisture probe to specific soils:
- Irrigate the turf thoroughly, then take readings with a soil moisture sensor one hour later. Measure in several spots and depths around the green;
- Repeat monitor in the same spots twice daily. Note visual any stress symptoms on the turf;
- Continue taking readings until turf shows symptoms of drought stress;
- Once these levels have been determined, use them help guide future irrigation events.
- Calibrate for each soil type
