Unearthing Agricultural Innovation


Map Soil Organic Carbon Rapidly and Accurately at a Fraction of the Cost

The Subterra Green inserts a probe into the ground, allowing us to measure and map the chemical content of the soil spectroscopically, eliminating the need for costly extraction, handling, and analysis of soil samples.


A Mobile Soil Laboratory

Currently the Subterra Green measures and maps soil organic carbon and bulk density to a depth of 90 cm. Capacity to measure other soil health and fertility indicators is under development.

Soil Organic Carbon

Why Choose Subterra Green?

Innovative Technology: Improve yields and be ready for soil carbon credits.

Cost-Effective: The Subterra uses no consumables and requires no soil samples. A 90-second insertion measures soil at depth increments to 90 cm. Detailed georeferenced maps are produced by dense sampling not feasible using conventional laboratory analysis of soil samples.

Subterra Green
