How the Subterra Green Captures Multi-Parameter Data in a Single Pass The Subterra Green uses near-infrared spectroscopy to read the soil as the probe advances through the ground. The spectral signal captured at each depth increment contains information about multiple soil constituents simultaneously — carbon, bulk density, water content, and the spectral signatures associated with nutrient concentrations and various physical and chemical soil properties.

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.

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.
