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 moisture from 0 (saturated) to 200 (dry) centibars.
