    Take A Video Tour Of
    Our Easy-To-Use     Irrigation App

    Irrigate with confidence with EarthScout. Our Irrigation App provides growers real time soil data in simple, interactive charts on their cell phone and laptop, 24/7.

    Description: Watch our Do-it-Yourself install video of our L4 Plus Soil Moisture Sensor in a garlic field with drip irrigation. In this video, we show you how to put L4 Plus in the soil, quickly dig a hole to install our research-grade TDR soil moisture sensors for monitoring soil moisture, soil temperature, and soil Electroconductivity (EC) at a 4” depth and an 8” depth. We then send a data packet to our mobile app to view the data in simple to read charts.

    EARTHSCOUT IRRIGATION APP DASHBOARD TOUR: In this video we have two EarthScout TDR Soil Moisture Sensors installed horizontally in the soil at a 6” and 12” depth (up to 4 TDR sensors can be installed up to 4′ deep). We walk through the Irrigation App dashboard, look at the soil moisture, soil temperature, soil electroconductivity (EC) reading for each EarthScout TDR sensor. We compare the two sensor depths to see the difference in moisture, temperature and EC readings, we look at the air temperature and humidity for the unit, and more.

    EXPORT YOUR DATA: In this video, learn how to export an Excel .CSV File (week, month, year, etc) for crunching your data, importing in into another application, or sharing it with others.

    KNOW THE LOCATION OF YOUR EARTHSCOUT USING GPS: Use our GPS Location feature in the EarthScout Irrigation App to quickly find the location of your L4 Cellular Soil Moisture Sensor on a map.

    Description: In this video, we show how growers can use the EarthScout Irrigation App to set up simple guidelines to ensure their soil moisture remains in the optimal range for plant growth. In the EarthScout Irrigation App, growers can set their Field Capacity (FC), Maximum Allowable Depletion (MAD), and Permanent Wilting Point (PWP). Then, growers can monitor their soil moisture levels in the app and adjust their irrigation to maintain the optimal moisture levels between Field Capacity and MAD. We can help you get set up in minutes… Just give us a call.

    EarthScout TDR Sensors – The Gold Standard: EarthScout Time Domain Reflectometry (TDR) sensors are considered the gold standard in precision sensors, and used in government & university research due to its accuracy and reliability. Measures soil moisture, soil temperature, and soil electroconductivity. Unlike capacitance based sensors, TDR Soil Moisture Sensors install into undisturbed soil, they don’t require calibration, and there is no risk of soil dry back issues, so you can install and uninstall them yourself in minutes and leave them in the soil all season long without worry. Plus, our commercial-grade sensors with stainless steel tines do not rust. Use in natural soil, Rock Wool, Coco Coir, Perlite, Peat, Sand, Clay, and more. Can also be used in high organic matter, high salt, and soil-less root zone mixes. Get an EarthScout Burial Tube for even faster TDR sensor install and uninstall.

    Plug In Up To 2 TDR Sensors To Monitor Soil At 2 Depths: Dig a hole using a shovel or our Soil Auger Drill Bit and insert your TDR Sensors into the sidewall of a hole at any depth. Insert a shallow TDR sensor to receive important data on the EarthScout Irrigation App for early season decisions. A deeper sensor will provide valuable insights as the roots move deeper in the soil later in the season. EarthScout TDR sensors install in undisturbed soil, and no calibration or slurry is required. Plus, with TDR sensors there is no risk of bad data or reinstallation due to soil dry back. Just insert the TDR sensor into the side of the hole at the depths you choose, fill in the hole with dirt, and leave the sensor in place all season long. Use an EarthScout Soil Auger bit, or an EarthScout Burial Tube for making sensor insertion quick and easy.

    How To Use L4 Data Readings: EarthScout L-Series Cellular Soil Moisture Sensors take data readings every hour and send the data to the EarthScout Irrigation App on your mobile device or computer. Use EarthScout to monitor conditions above and below ground and always know when, were, and how much to irrigate. Soil Moisture: View trends in your data and see how water is moving through your soil profile, see how much water your plants are taking up, estimate your field capacity, and dial in your irrigation. Soil Temperature: Monitor soil temperature at multiple depths to make the most informed planting and fertilizing decisions. Soil Electroconductivity (EC): See the concentration of salts in the soil and determine if fertilizers are moving through the soil profile. Air Temperature & Humidity: Environmental data collected in field allows for the calculation of hyperlocal growing degree (heat) units specific to that location for crop or pest growth stage monitoring.

    Monitor Any Crop Real Time, 24/7: EarthScout L4 Cellular Soil Moisture Sensors are the perfect solution for monitoring your fields. It’s great for use on a farm, vineyard, or orchard, and for research, and education. It can monitor any crop, including corn, soybeans, potatoes, grapes, wheat, fruits, vegetables, citrus, nuts and rice.
