Agricultural & Precision Farming

  • Field Moisture Mapping & Transects: Enables spatial profiling of soil moisture across fields to support precision irrigation and crop management
  • Optimizing Irrigation Scheduling: Provides real-time volumetric water content (VWC) data to avoid under- or over-watering

Remote Sensing Ground Truthing

  • Calibration & Validation: Calibration measurements for satellite or drone remote sensing of soil moisture, enhancing accuracy of remote datasets

Environmental & Hydrological Research

  • Research-grade In Situ Sampling: Offers a field-based alternative to oven-drying for moisture determination
  • Contaminated Site Monitoring: Supports tracking of soil moisture in remediation or ecological studies

Geotechnical & Construction Engineering

  • Site Investigation: Valuable in characterizing moisture variations in soils for slope stability, embankments, and dam foundations

Academic & Soil Science Studies

  • Pedological Research: Enables rapid profiling of moisture at multiple depths, aiding research into soil texture, structure, and hydrology

Precision Field Studies & Environmental Monitoring

  • Point Measurements in Diverse Conditions: Works from 0–100% VWC with ±2% accuracy—even in high-salinity or high-EC soils where other sensors struggle
  • Use in Extreme Soils: Coated probes resist corrosion; slam-in probes tolerate rocky/clayey soils

Soil-Probe Versatility & Depth Profiling

  • Multiple Probe Lengths: Configurable from ~8 cm to 60 cm, enabling measurements at varied soil horizons across disciplines

Field Data Management & Documentation

  • Integrated GPS & Geotagging: Records exact locations of readings for mapping and tracking
