What the SMT 100 Soil Moisture Probe Measures
The SMT 100 Soil Moisture Probe (VSW%) measures volumetric soil water content, 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 growth, irrigation timing, and root-zone management, dependable measurement is essential in both practical agriculture and technical monitoring work.
The SMT 100 uses an electromagnetic signal travel time approach at high frequency above 100 MHz, allowing it to provide reliable soil moisture output even in more difficult soil conditions, including clay-rich soils. In the broader monitoring context, the SMT 100 is also used where users need a practical and easy-to-install solution that can contribute valuable soil moisture data to field programs, research studies, and integrated monitoring systems.
Volumetric Soil Water Content
Measures volumetric soil water content to support irrigation scheduling, root-zone monitoring, and soil water interpretation.
High-Frequency Measurement
Uses an electromagnetic signal travel time method operating above 100 MHz to support dependable soil moisture sensing.
Performance in Clay-Rich Soils
Designed to provide accurate measurement even in clay-rich soils where other methods may be more difficult to interpret.
Practical Field Integration
Supports field and research applications where users need a soil moisture probe that is practical to deploy and useful in ongoing monitoring programs.
Irrigation Scheduling
The SMT 100 helps users monitor soil moisture more effectively, supporting better irrigation timing and improved water-use decisions.
Root-Zone Monitoring
By measuring volumetric soil water content, it provides useful information about water availability within the root zone.
Soil Monitoring in Clay-Rich Conditions
Its measurement approach makes it especially useful in soils where clay content can make moisture assessment more challenging.
Agricultural and Research Use
The SMT 100 is relevant in crop monitoring, field studies, and research applications where consistent soil moisture information is important.
Integrated Monitoring Programs
When used alongside plant monitoring, environmental sensors, and logging systems, the SMT 100 contributes to a more complete understanding of field conditions.
