S4 Mobile Laboratories is pleased to announce it has been named a Morgan Startup Grant recipient for the second consecutive year

Every agronomist knows the frustration: you pull samples from a field, send them to a lab, wait days for results, and by the time the report arrives, the planting window has narrowed, or passed entirely. Traditional soil testing was designed for a different era of farming. Precision agriculture demands something better. The Problem with Point-in-Time Sampling Conventional soil testing captures a snapshot from a handful of locations, averaged across acres that are rarely unifo

S4 pilot projects are built on collaboration, not a hand-off. You bring your agronomic expertise and soil sampling capability, we bring the Subterra Green. Together, that combination produces something neither party could generate alone: high-resolution, geo-referenced soil data mapped across your specific field conditions.

The Subterra Green was built on a simple but powerful idea: farmers and agronomists deserve real-time, in-field soil data — not lab results that arrive days later when decisions have already been made. That vision started with soil organic carbon, water content, and bulk density. Today, we're sharing where it's heading next. What the Technology Makes Possible At the heart of the Subterra Green is near-infrared spectroscopy — a sensing approach capable of detecting hundreds of

At the 2026 Conservation Tillage & Technology Conference, S4 Mobile Laboratories' Principal Scientist Linda Barrett presented the culmination of nearly two years of grant-funded research.

Continuous, in-field spectroscopic measurement addresses several of these limitations simultaneously. By measuring soil organic carbon, water content, and bulk density to 90 cm without laboratory extraction, sample handling, or extended processing time, it becomes possible to generate depth-resolved profiles at the spatial density and precision that field-scale variability actually demands.

High-resolution depth mapping fills the gap that surface tools leave open. When you can see soil organic carbon, water content, and bulk density continuously from the surface to 90 cm — in real time, in the field — the picture of what's driving variability becomes considerably clearer.

At the Conservation Tillage & Technology Conference (CTTC), S4’s Linda Barrett will explore how this transition from samples to systems looks in practice. Her session, “Seeing Beneath the Surface: Digital 3D Maps of Soil Organic Carbon” on March 11 will show how S4's Subterra Green digital 3D mapping can support more precise AG decisions in conservation tillage and soil health strategies.

In just a few days, they collected 10,900+ soil organic carbon data points using the Subterra Green with instant results delivered right in the field.

Field-deployable lab platforms are rewriting those rules. By bringing advanced analytical capability directly to the farm or research site, they shrink the distance between observation and insight.

What is changing in 2026 is not just the volume of data available to agriculture, but how fast and how locally it can be captured and turned into profit-driving decisions.

S4 Mobile Laboratories attended The Desert Difference AgTech Conference in Yuma, Arizona, a two-day event held November 13–14, 2025 that brought together growers, startups, researchers, and technology partners focused on the future of farming in arid regions.

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.

S4 Laboratories was honored to be named a recipient of the prestigious Morgan Startup Grant, made possible by the Burton D. Morgan Foundation in partnership with Bounce Innovation Hub. This grant program is uniquely designed to help early-stage companies transform bright ideas into tangible innovations that create both economic and societal value. For S4, the funding has provided vital resources to advance our technology platform and expand its applications into areas of real

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.

S4 Mobile Laboratories, a leader in mobile soil analysis solutions, has been awarded a $2,000 Morgan Startup Grant, introduced by Bounce Innovation Hub and funded by the Burton D. Morgan Foundation.
