The specialist for matric potential (soil water tension) measurement

The Walter soil sensor is your reliable partner for precise soil monitoring and offers you innovative technology combined with a proven method. Equipped with a Watermark-Sensor from the manufacturer Irrometer and a PRT class A temperature probe, Walter delivers precise data on soil moisture and soil temperature. It is available in two variants: with one or two soil probes, depending on your individual requirements.

What makes Walter special?

1. Watermark-Sensor – A proven solution

The Watermark-Sensor does not measure the percentage water content of the soil, but rather the so-called matric potential (soil water tension). This indicates how much energy a plant has to expend to extract water from the soil. Walter thus acts like an artificial root that shows you directly whether your plants are sufficiently supplied.

2. No calibration required

Unlike other methods, the Watermark-Sensor needs no complicated calibration for different soils or locations. This saves you time and guarantees reliable results regardless of local conditions.

3. Soil temperature measurement with precision

Thanks to the PRT class A temperature probe, Walter delivers highly accurate data on soil temperature. This information helps you determine the ideal time for tillage or sowing.

4. Flexibility with 1 or 2 probes

Walter is available in two variants:

1-probe model: Ideal for many measuring points at different spots in your fields.

2-probe model: Perfect for monitoring different soil layers or larger areas at the same time.

Areas of application for Walter

Efficient irrigation planning:

Measuring the matric potential (soil water tension) helps you optimize your water consumption and ensure that your plants receive neither too much nor too little water.

Targeted tillage:

With the precise data on soil temperature, you can plan work such as soil loosening, sowing or planting exactly.
