Created: ; updated: .

Description

The Sentek Drill and Drop Soil probes can measure soil moisture, temperature, and (optionally) salinity along the length of the probe at every 4" (10 cm).

Applications

The Sentek Drill and Drop Soil probe, used in combination with Observant Global, paints a complete picture of what’s happening in the soil profile by combining soil moisture, salinity and temperature readings. Undisturbed installation allows for measurement of truly representative soil profile, not slurry mix. It is ideal for seasonal use, such as monitoring vegetable crops, due to the fast and easy install and extraction techniques. Applications include

  • Vegetable crops
  • Fruit & Nut tree crops
  • Berries
  • Vines
  • Research
  • Landscapes
