Hybrid in-soil biological activity monitoring system

Overview

INDEX Terra Bio represents a groundbreaking advancement in agricultural and environmental monitoring technologies. It is an in-soil sensing system specifically designed to track biological activity under real field conditions. By leveraging multiple proxy signals such as soil respiration (CO₂), redox potential, moisture, and temperature, the system provides a reliable and consistent indicator of biological activity. Unlike traditional single-measurement methods, it resolves ambiguities by analyzing the relationships and temporal trends among these signals. This approach allows for scalable field deployment and precise evaluation of biological inputs, making it a valuable tool for agronomists and environmental scientists.

Technical specifications

Features of INDEX Terra Bio include:

• Multi-signal sensing: Simultaneous measurement of CO₂, redox potential, moisture, and temperature directly in the soil.
• Automated data acquisition: Continuous, automated logging of data, ensuring consistent monitoring with minimal manual intervention.
• Calibration and drift correction: Periodic reference measurements are used to calibrate the system and correct for any drift, ensuring high accuracy.
• Compact and robust design: Designed for easy integration into various soil types and management conditions.

Technology readiness level

The technology is currently at TRL 2, indicating that the concept and application have been formulated and the key components have undergone initial testing under controlled conditions. Future development phases include building compact probes with automated data logging, developing interpretation models, and deploying field trials to further validate and refine the technology.
