Sentek Drill & Drop™

(2 customer reviews)

Fully encapsulated soil moisture profile probe using capacitance based measurements.



The Drill & Drop is a fully encapsulated, easy to install, soil measurement probe. Probes are available in four lengths, 30cm (12?) (SDI-12 only), 60cm (24?), 90cm (36?) and 120cm (48?), with sensors fixed at every 10cm (4?) increment. It is also available as a single point sensor. Purchase options are any length with soil moisture + temperature sensors or soil moisture + temperature + salinity.

Due to the ease of install and protected electronics, the Drill & Drop is ideally suited to situations where a monitoring probe may need to be moved between sites in short-term and annual crops. Having the electronics completely encapsulated and able to be completely buried also makes the probe suited to long-term installations, where machinery will pass often, such as dryland and feed crops. Being able to leave the probe in the ground means long-term, uninterrupted data trends and comparison between seasons is possible.

The Drill & Drop also covers the issue of data continuity and integrity where the probe does need to be reinstalled. The ingenious tapered probe and matching auger allows direct, slurry-free, installation. This direct installation method means that the probe is measuring ?real? representative soil conditions immediately after install, because the surrounding soil has not been disturbed.

  • Single point sensor and 30cm (12?) probe available

Additional information

Salinity Measurement (Optional)

Salinity is measurement provided is "Volumetric Ion Content (VIC)". This is a proprietary measurement derived by Sentek that represents the presence of all charged ions in the soil. This value can be related to Electrical Conductivity (EC), but a benchmarking procedure is required. The details of this procedure can be found on page 33 in the "TriSCAN Users Manual": Even without relating the VIC value to EC, the data can be quite useful to determine salinity increases with fertilizer additions and long term increases in field salinity status.
