Superintendents must consider the type of soil, species and ET rate for the best possible conservation method and use accurate timing methods to control the frequency and duration of water. It is also important to find and fix leaks in the irrigation system quickly and cap sprinkler heads in nonpriority watering areas. The ultimate management goal is to achieve the lowest ET rate possible in order to make the best use of the irrigation water. It is vital to consider soil and species when deciding to replace turf. Some superintendents use sophisticated computerized irrigation systems and monitor the weather through on-site weather stations to make sure the course is not watered right before it rains.
Superintendents can also use water-retaining agents in the root zone.
Polymers are sponge-like granules made of synthetic material or starch that can absorb large amounts of liquid. They then contract and release the stored water into the soil. In this way, polymers can reduce the amount of water lost through percolation and evaporation, thus reducing irrigation requirements. In addition, they dissolve nutrients and absorb herbicides and pesticides. Polymers can be expensive and difficult to inject into the soil.
