Soil moisture sensors
Soil moisture is the water content (also moisture content) of the soil - that is, the amount of water contained in a soil at a specific point in time. Our various sensors measure the gravimetric or volumetric water content proportionally or in volume %. When installing the soil moisture sensors make sure that the measuring rods have a good contact to the surrounding soil. Air-filled hollow spaces between the soil and the rods lead to distorted measurement results. An insertion tool with thinner rods than those of the probe facilitate the installation and enable a good contact.

- Knowledge of other physical properties of soils (plasticity, consistency, bearing capacity, etc.)
- Measurement data for water balance studies
Frequently Asked Questions (FAQs) About Measuring Soil Moisture
Soil moisture can be determined using various measurement techniques. Scientific applications commonly use capacitive sensors as well as FDR, TDR, and TDT technologies. These methods determine volumetric water content based on the dielectric properties of the soil and enable continuous high-resolution monitoring. UGT offers soil moisture sensors based on various methods, some of which are combined.
Soil moisture only describes the amount of water stored in the soil. It does not indicate how strongly the water is bound to the soil matrix. Combining soil moisture with soil water potential provides a much more realistic assessment of plant-available water and water movement.
The accuracy of soil moisture measurements is influenced by the measurement principle, soil properties, salinity, temperature, calibration, and proper sensor installation. Selecting a sensor and installing it correctly for the specific application is crucial for reliable results. We would be happy to advise you on choosing the right solution.
