Water & Nutrient Management:
Soil Moisture-Based Irrigation Systems
Irrigation Components
A standard irrigation timer is presented in this video. This is an essential component used in conjunction with the soil moisture sensor to control the irrigation. The soil moisture sensor is used to automatically bypass scheduled irrigation events when the soil moisture is above a desired irrigation set point.
