Soil Moisture

Equipment for following water in the soil and deciding when and how much to irrigate. There are handheld TDR meters for quick readings at many points, profile probes that measure moisture and temperature at several depths, buried sensors with SDI-12 output and solar-powered loggers that stay in the field.

Kits and IoT systems combine soil moisture, conductivity and temperature, and nutrient sensors for nitrogen, phosphorus, potassium and nitrate serve precision agriculture.
