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.
