The water usage efficiency is quite high, and if proper planning is done, it provides maximum benefit from water where there is a minimum water source. It prevents erosion that may occur with irrigation on sloping lands.
Since the water is given to the soil in a small amount and at a rate close to the soil’s water intake rate, surface runoff does not occur in general. At the time of seed germination, it is eliminated if the plant does not rise above the soil due to the cream binding of the soil.
Since it is possible to provide controlled water with sprinkler irrigation; It is the most suitable irrigation method in places with high ground water and drainage problems. It saves time. It provides convenience in workmanship.
What should be considered when placing sprinkler pipes?
The main pipeline should first be placed in the direction of a certain slope. Sprinkler laterals should be perpendicular to the prevailing slope and parallel to the leveling curves as much as possible. The movement of the laterals on the main line should be arranged in a way that requires minimum labor.
According to the strength of the wind, the laterals should be placed at a right angle. The system should be arranged as square or rectangular as possible in order for the lateral movements to be easy and the number of heads working together to be low.
The pipe sizes and arrangement of the system should be in a way to minimize the annual costs. If the facilities allow, the pumping unit should be placed in the middle of the area, as it will allow the selection of suitable and economical pipe diameters.
For this reason, it should be preferred to make irrigations with the sprinkler method during cool hours. It is not suitable for irrigation in windy weather. Since a balanced irrigation process will not be carried out, windless weather should be preferred for irrigation to be made in sprinkler irrigation methods.
What are the issues to be considered in the maintenance of sprinkler irrigation systems?
Before installing the gaskets of the pipes, clean the gasket channels. In fixed and semi-fixed systems, a pressure test should be made and then the top of the pipes should be covered. In fixed and semi-fixed systems, the pipes are buried at a depth of at least 40 cm in regions with mild winters, and at least 70 cm in regions with heavy winters.
If the motor is powered by electricity, a ground line must be made. Care must be taken not to touch the electrical wires while the pipes are being transported. The lateral and main pipes should be filled with water by running the system at a low flow rate first, and the pipeline should be cleaned by opening the blind plug for a very short time.
A filter or filtration system must be installed in the pump suction pipe in order to prevent foreign substances from entering and to prevent the sprinkler nozzles from clogging. The displacement time of the laterals must be determined.
