| Abstract/Contents: | "Very often it is the poor application of water that robs us of good results. Therefore it is vital in turf management to understand irrigation practices and what effects these will have. Understanding is achieved when our knowledge of a subject is from the grass roots level. The 'turf' to be watered will require a sprinkler of some kind. There are two main types." One is the spray sprinkler. "This type of sprinkler is a small radius sprinkler by design. It uses a deflector plate to shape the pattern of spray, to set the angle of trajectory and to some extent, the droplet size." The other type of sprinkler is rotor sprinklers. "The rotor, as its name implies, uses a rotorary action to distribute the water. The result in this case allows a much larger area to be irrigated. The Rotor however requires a drive force to do the rotation. How this drive is obtained is important as it will affect the srinkler in some way, giving this type of sprinkler certain unique characteristics. We must manage the watering and this may now mean taking into consideration the available watering time or perhaps more correctly the the time we want it to be watered, the infiltration rate of the soil, the effect of wind, maintenance costs, noise and water quality. These considerations will affect the choice of sprinkler... As water quality deteriorates, the demands on the irrigation equipment escalates. The use of dirty or effluent water is becoming common, but it is with some cost. The impurities can affect sprinklers in a number of ways. Corrosion can be accelerated because of the dissolved salts and nutrient-rich additives. Erosion and wear can be a new factor due to a much higher count in suspended solids. Odour and algae growth also become important factors requiring much work in keeping them at acceptable levels. How this interacts with sprinkler type and selection is important and should be addressed taking everything into consideration." |
