NOAA soil observations
Soil Temperature & Moisture
Compare soil conditions at five depths across climate reference stations.
Depth profile
Why the layers matter
Shallow soil responds quickly to sun, rain, and overnight cooling. Deeper layers change more slowly and help show the stored seasonal signal beneath short-lived surface swings.
Seed-zone response
The most responsive layers for following rapid warming, cooling, and wetting near the surface.
Root-zone bridge
A useful middle layer for seeing whether a surface change is beginning to propagate downward.
Seasonal storage
Deeper observations move more slowly and reveal the ground’s longer thermal and moisture memory.

A Bluegrass-region profile for comparing warmer and wetter soil regimes.
Open soil profile →USCRN stations are high-quality climate reference sites, not field-specific agronomic prescriptions. Conditions can differ materially across soil types, slope, cover, drainage, tillage, and distance from the station. Use local extension guidance and in-field measurements for operational decisions.
