Soil analysis probe – Sentek, Drill and drop
Soil probe technology measuring at multiple depths for precision irrigation management.

Benefits
The Drill and drop can be used to monitor daily water use, infiltration rate, and drainage below root zone.
The data collected can help inform decisions about:
- irrigation timing
- chemical application
- general soil health management.
This improves efficiency and saves resources when analysing paddocks and developing farm management plans.
How it works
The probe is available in lengths of 30, 60, 90 and 120cm, with sensors located every 10cm. It measures moisture, salinity and temperature.
Soil profile data is updated continuously, providing a current view of what is happening in the crop root zone. The data is accessible online through Sentek’s IrriMAX Live dashboard, or mobile app.
Alerts can be created for specified moisture thresholds. Sentek can also integrate into other farm management software, such as weather stations, data loggers and irrigation controllers.

Installation and power
The probe can be installed by the producer, or by Alpha Group Consulting. It involves drilling a hole with a proprietary tapered auger and inserting the tapered probe, which can be buried to any depth. This allows machinery to work the upper soil layer.
Power is supplied by a long-life or rechargeable battery, with solar panel charger.
Connectivity requirements
The probe is connected to a data transmission unit via cable, and data is sent to the online software program by 3G, 4G, 5G, or satellite.
Pricing model
Upfront cost and ongoing fees for IrriMAX Live.
