Soil Moisture Sensors
Maintaining a healthy water balance is essential for producing high quality plants. Under-watered plants suffer from nutrient deficiencies, stunting and wilting. Conversely, over-watered plants are more susceptible to disease pressure and less tolerant of dry conditions later on in their life cycle. Extreme over-watering will suffocate the plant and lead to root death.
The WaterScout SMEC300 Soil Moisture Sensor is a combination sensor using Time Domain Multiplexing technology to measure not only Soil Moisture (%VWC), But also Soil Conductivity (EC in mS/cm¹) and the Soil Temperature (°C). The WaterScout SMEC300 is the most advanced sensor in our portfolio and can be used in combination with most of our FieldGuard Stations.

The WaterScout SM100 Soil Moisture Sensor is a capacitance type sensor that measures Soil Moisture Content (%VWC). The sensor responds immediately to changes in Soil Moisture Content helping you to make better irrigation decisions. Under-watered plants suffer from nutrient deficiencies, stunting and wilting. Conversely, over-watered plants are more susceptible to disease pressure and less tolerant of dry conditions later on in their life cycle. Extreme over-watering will suffocate the plant and lead to root death.

The Watermark Soil Moisture Sensors is an established method of tracking soil moisture trends in crops, vineyards, or other areas where moisture level is a concern. Place sensors in the upper and lower thresholds of the root zone, in turf, or in other growing media. Reads soil moisture tension from 0 (saturated) to 200 (dry) centibars.
