Enter the Subterra Green: this breakthrough mobile lab technology is transforming the way soil health challenges are detected and addressed.

Switching from traditional laboratory soil testing to the Subterra Green’s mobile platform changes the game for farmers and service providers.

Earlier this month, S4 celebrated an important milestone: Russell Pier and Morgan Revels successfully completed the Ohio Peace Officer Training Academy (OPOTA) forensic certification course.

Angela Burant, co-founder and director at askîhk Research Services, for a candid conversation about her team’s mission and how S4’s technology has become an integral part of their toolkit.

Recent advances in visible and near-infrared (vis-NIR) spectroscopy have revolutionized our capacity to measure SOC in situ. Peer-reviewed studies consistently demonstrate that vis-NIR instruments, when properly calibrated, deliver rapid, reliable, and spatially resolved data on SOC and bulk density. This technology enables dense sampling grids and three-dimensional mapping—critical for both baseline establishment and ongoing verification demanded by carbon programs.

Recent advances in soil spectroscopy like S4 Mobile Laboratories’ Subterra Grey are transforming the landscape of subsurface investigations.
