Irrigation is the process by which a controlled quantity of water is supplied to plants at regular intervals for various purposes. For several centuries, human beings have used artificial means to support growth of plants by providing them with water. Mesopotamia, ancient Greece, Egypt, and the Roman Empire are some of the ancient civilizations that thrived on using irrigation to support plant growth to boost harvest.
Today, better methods of irrigating plants have been invented to replace the old, labor intensive methods used in the past. Initially, irrigation was mostly done to support the growth of agricultural crops, but that has changed as the process is used for several other purposes. One of the new uses of irrigation is maintenance of landscapes. Golf course irrigation is mostly done to maintain the landscape.
Other reasons for irrigating land are to prevent the growth of weeds and to revegetate soils in arid areas. Additional reasons are prevention of consolidation of soil and protection of plants from frost. Systems used to deliver water can also be used for multiple purposes. For instance, they are used in mining, dust suppression, and sewage disposal.
There are three types of irrigation and all of them can be used to irrigate golf courses. The three types of irrigating methods are surface irrigating, in-ground irrigating, and sub-surface irrigating. Surface irrigating is the commonest method in use. Surface irrigating involves installing irrigating systems and infrastructure above the ground. Sprinklers are good examples of surface irrigating systems. Sprinkler systems are use a lot on golf courses because they are convenient and effective.
Sub surface irrigating is almost never used on courses because of the way it works. In this method of irrigating, the water table is usually raised to irrigate the land. Water from the water table moistens the soil below the root zone. Drainage infrastructure is usually incorporated to control how much moisture is made available to the soil from the water table. This method is predominately used on river courses and permanent grasslands in lowlands.
All the components that are used to supply water in an in-ground irrigating system are usually buried inside the ground. Among the components buried are emitters, sprinklers, irrigating valves, and pipes. The fact that the components are buried makes the landscape to appear more presentable and cleaner. However, this also makes repair and maintenance problematic. Serious damage may have to be done to the ground to access the components during repair.
The irrigating system is normally subdivided into various zones, with the different zones connected through tubes and pipes. It is necessary to subdivide the irrigating system so that the required pressure level can be achieved in each zone. It would be difficult for the water to have an considerable pressure if the irrigating system is not subdivided. As such, it would be impossible to apply water in all the zones at once.
Each zone is installed with a solenoid valve for controlling the supply of water. The controlling is done through an irrigation controller. The irrigating controller determines when a given zone is to be irrigated and how long the water should be applied.
