What the MP406 Soil Moisture Sensor Measures
The MP406 Soil Moisture Sensor is designed to measure volumetric soil water content over the long term, helping users understand how much water is present in the soil and how that changes over time. Because soil moisture plays a critical role in plant production, irrigation timing, and root-zone management, reliable measurement is essential for both research and practical field use.
Using Amplitude Domain Reflectometry (ADR), the MP406 provides a dependable approach to soil water content monitoring and can be calibrated for high accuracy where site-specific precision is required. It is suited not only to standard agricultural soils, but also to more demanding environments such as saline soils, landfills, and mine sites. With its reinforced body and stainless-steel needles, the MP406 is built for field durability while supporting consistent soil moisture measurement across long monitoring periods.
Volumetric Soil Water Content
