Why use a Rain Barrel?
Soil Moisture Sensors
A Soil Moisture Sensors (SMS) is a sensor connected to an irrigation system controller that measures soil moisture content in the active root zone before each scheduled irrigation event and bypasses the cycle if soil moisture is above a user-defined set point. SMSs function similarly to rain sensors by bypassing irrigation events under rainy conditions, but by measuring soil moisture at the root zone they are more effective at minimizing irrigation when plants do not need additional water.
In addition to conserving water, soil moisture sensors can also prevent issues like fertilizer runoff and will protect surrounding waterways.
