When applied to landscape irrigation, evapotranspiration (ET) can save you money. Evapotranspiration is defined as the amount of water that is lost from the soil through evaporation and plant use. Factors that affect evapotranspiration are: length of day, temperature, humidity, and rainfall.
These irrigation scheduling devices use principles of the soil water balance to schedule irrigation amounts and timing. The basic operation of ET controllers is described in What Makes an Irrigation Controller Smart.
So what are the benefits of using a smart ET controller?
- Decrease in irrigation costs – can reduce water usage by 20-50%
- Tax incentives – a growing number of government entities are offering tax rebates for use of smart controllers
- Good for the environment: 1) Reduces runoff 2) Reduces water usage 3) Healthier plants
