FN-SRTP Tubular Soil Monitor
Multi-depth root zone monitoring — up to 10 layers, solar-powered, wireless
The FN-SRTP measures soil moisture and temperature across up to 10 depth layers within a 100 cm profile. Solar-powered with 4G or 433 MHz wireless communication — providing complete root zone visibility without field wiring.
our core strengths
Proven at Scale, Built for Performance
Farmnet manages the variables that determine crop consistency and operational efficiency. Systems are deployed across greenhouse, open-field, and indoor production environments, providing real-time control of temperature, humidity, CO₂, water delivery, and nutrient dosing.
Operating at national scale within the world's largest agricultural economy. Farmnet systems support dense networks of greenhouse and open-field operations across the highest-intensity production regions.
End-to-end production capability. Controllers, fertigation units, and system components are designed, produced, and validated within Farmnet's dedicated industrial facilities.
More than a decade of continuous development in agricultural control systems, refined through multiple technology generations and operational requirements.
Multidisciplinary engineering organisation focused on agricultural automation, control architecture, hardware design, and software systems.
Systems operating across diverse climates and production models—from arid environments to advanced controlled-environment agriculture.
Thousands of systems in continuous 24/7 operation, generating long-term performance data that informs system reliability and design.

Key Features
Vertical root zone profile
See exactly how water moves through the soil profile at each depth — identify wet and dry zones, track irrigation penetration depth.
Solar-powered wireless
No field cabling or mains power required — operates continuously from solar energy with battery backup.
Precision irrigation decisions
Multi-depth data enables precise irrigation timing based on where water actually is in the root zone, not surface estimates.
Ecosystem
Works Together With
Irrigation Controllers
Soil moisture data at multiple depths triggers and adjusts irrigation cycles.
