We also suggest using matched precipitation, high-efficiency nozzles and sprinklers with built in pressure regulators for irrigating turfgrass. The larger water droplets are less effected by evaporation than high pressure sprayers.
Also, with sprinkler irrigation, you have inefficiencies in the step up that can contribute to water waste, such as water that sprays on hard surfaces where it is evaporated or runs off into storm drains.
On the other hand, drip irrigation, when using dripping emitters, releases water at a rate of gallons per hour. Water drips slowly from the irrigation emitters onto the surface of the soil. Water is applied directly to the soil around desired plant material closer to the root zone. If water is applied underneath mulch, moisture is held longer in the soil because mulch insulates and protects against increase evaporation during hotter months.
