Radicle™ Soil Carbon Sensor

Real-time soil respiration monitoring — built for the field, not just the lab

The SEED Radicle™ draws its name and inspiration from the primary, embryonic root of a plant. It tracks biological soil activity by measuring CO2 levels in the root zone, giving users fast, actionable insight into soil health and recovery. 

Radicle sensor in soil

VALIDATED IN THE FIELD

“The sensor helped us track change before it was visible above ground.”

In early field tests:

  • 91% of readings fell within accuracy targets for CO2 sensing

  • Sensor performance held steady across multiple soil types and moisture levels

  • Detected increased respiration after biochar and fungi amendments, aligning with plant recovery and carbon retention

Grounded in Soil Respiration Science

  • Radicle uses NDIR sensor to detect CO2 concentrations in soil airspace

  • CO2 levels reflect microbial activity — the engine of soil carbon cycling and biological health

  • It’s a proven method for assessing soil vitality, ideal for monitoring amendment effects, remediation progress or regenerative practices.

Built for Field Conditions

  • Handheld and rechargeable for easy site-to-site use

  • Rugged enclosure; tested in wildfire-affected, urban and sandy soils

  • Used by growers, educators and researchers

Live Data, No Guesswork

  • Plug-and-play: insert in soil, leave for 15 minutes, read CO2 ppm

  • Onboard display for immediate feedback

  • Mobile dashboard stores readings and charts trends by location

Machine Learning at Work

Each time a Radicle™ sensor collects data, it contributes to a growing dataset used to train our machine learning models. These models will identify patterns in soil recovery, predict amendment effectiveness and eventually provide site-specific recommendations. We’re not just measuring, we’re learning. And as more growers deploy Radicle™, the system becomes smarter, faster and more helpful.
