Efficient Irrigation
By establishing water use zones we are trying to minimize the amount of supplemental water required for irrigation. Irrigation may be a necessity but it should be applied in the most efficient and effective manner to make sure that maximum benefit is received from the minimal amount applied.
Since we have established water
use zones it only makes sense to establish irrigation zones that match.
Irrigation is applied just enough for the needs of the plants in each
zone. The water requirements within a zone may vary depending upon
the type of planting. For example, new plants will need more
supplemental water while that are getting established.
The method of applying the supplemental water will vary also. Since plants in low or moderate water use zones do not need water on a regular basis, temporary watering systems such as hoses or watering cans may be used. High use areas may warrant the installation of a permanent system. All permanent systems need to be well designed to evenly distribute water in the correct area and they should have automatic controls. Whenever possible efficient watering systems such as drip irrigation should be used.
Whatever water is applied to the landscape, whether it be from natural rainfall or from irrigation, it should be retained in the soil for as long as possible in order to maximize the benefit. This is accomplished through the Use of Mulches principle.
