WaterScout - Model SM 100 - Soil Moisture Sensor
Maintaining a healthy soil moisture and 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.
- Measures Volumetric Water Content (VWC) of soil
- Capacitance-type sensor responds immediately to changes in soil moisture content for better irrigation decisions
- Calibrated for mineral soils or soilless media
- Installs easily into 3/4 in (1.9 cm) hole
- Install permanently or use to take spot measurements
- Can be read with the FieldScout Soil Sensor Reader (Item 6466) or WatchDog® 2000 and 1000 Series Stations
- Connect up to 8 sensors to one station Not compatible with 400/200 loggers. WatchDog Stations sold prior to 2009 must be upgraded. (call for support)
- NEW Calibration feature: Sensors with '3/14' code can be re-calibrated using the FieldScout Soil Sensor Reader (item 6466) or the WaterScout Calibration Device (item 6470CAL3V). Please see the product manual for calibration proceedure.
The product feature begins at 13:30 of the video. In episode 12 of Corn College TV season 2, head to the field with Farm Journal Associate Field Agronomist Missy Bauer. She shows how her crew is using a technology from Spectrum Technologies to monitor irrigation efficiency.
