Read moisture trends, compare depths, and make better-informed irrigation decisions.
A shallow sensor may rise after irrigation while a deeper one barely changes. That contrast can show how far water traveled, but one reading cannot tell the whole story.
Many probes report volumetric water content: the volume of water relative to the volume of soil. Other sensors measure how much effort roots need to extract water.
Start with readings from a correctly installed sensor, then track changes before and after rain or irrigation. Repeated patterns under similar conditions are more useful than isolated values.
Record rainfall, irrigation timing, crop stage, and other relevant field observations alongside sensor readings. These details help explain why moisture rose or declined over time.
Water moves unevenly through soil. Texture, compaction, slope, drainage, and irrigation coverage affect where it collects and how quickly it reaches sensors across a field.
A sharp change without a likely rain or irrigation event deserves a closer look. Compare nearby probes and check installation, soil contact, placement, and connections before acting.
A drying trend in the active root zone may call for closer monitoring or irrigation planning. Also consider crop demand, root depth, forecast weather, and irrigation capacity.
If a shallow probe rises after irrigation but a deeper one stays steady, allow time for water to move. If the pattern persists, inspect soil, emitter flow, and probe placement.
When one sensor drops sharply while nearby probes remain stable, check its connection and surroundings. Compare the field conditions before treating the reading as a real change.
Choose representative sensor locations, record depth and position, and review trends regularly. Pair each decision with field observations and the action taken to improve future interpretation.
