Interpretive Summary:

Technical Abstract: Various types of soil moisture sensing devices have been developed and are commercially available for water management applications. Each type of soil moisture sensors has its advantages and shortcomings in terms of accuracy, reliability, and cost. Resistive and capacitive based sensors, and time-domain reflectometry sensors have been rapidly developed and adopted for soil-water measurement in recent years. Some of these sensors are integrated with wireless data communication devices making it capable of wirelessly transferring the soil moisture data. Researches showed soil moisture sensors could be used as an irrigation tool for saving water. However, procedures for proper installation, calibration, and maintenance of soil moisture sensing devices are critical for the success of soil moisture sensor-based irrigation scheduling. An example of practical use of soil moisture sensors for irrigation scheduling in humid region is given.
