In this article, we are going to see the advantages of rain gun sprinkler irrigation system.
In rain gun sprinkler irrigation system, water is piped to one or more central locations within the field and distributed by overhead high-pressure sprinklers or guns. Higher pressure sprinklers that rotate are called rotors and are driven by a ball drive, gear drive, or impact mechanism. Rotors can be designed to rotate in a full or partial circle. Guns are similar to rotors, except that they generally operate at very high pressures of 275 to 900 kPa (40 to 130 psi) and flows of 3 to 76 L/s (50 to 1200 US gal/min), usually with nozzle diameters in the range of 10 to 50 mm (0.5 to 1.9 in).
Advantages of Rain Gun Sprinkler Irrigation System
- Highly Efficient Portable System
- Long enduring and maintenance free
- Lightweight, sturdy and easy to shift.
- Uniform sprinkling with condition to calibrate droplet size and rainfall rate, suitable to all soils and crops.
- Quick fit accessories for connecting to PVC or G.I. or HDPE main lines.
- Early sowing & better germination of seedling through optimum moisture condition of soil which is possible by Rain Gun Sprinkler System.
- Rain Gun irrigation plays the role of Nitrogen fixation. As rain gun resembles rain, the water dissolves the nitrogen from air and gives it to soil, thereby adding nutritive value to soil.
- Liquid fertilizer can be applied quickly over large areas. It saves on fertilizer quantity; foliar application hence results in good yield.
- Reduces labor and pipeline cost
- Reduces pest and insect attacks
- This lessens the irrigation time and save diesel
- Rain gun sprinklers operate at different pressures, rotating at uniform speed and can be adjusted to cover part or full circle.
- Prevents salination caused due to over irrigation thus maintaining soil productivity
Disadvantages of Rain gun sprinkler irrigation systems
- Large numbers of trees make it difficult to sprinkle uniformly.
- The rain gun and the raiser pipes are very heavy.
- High day time temperatures result in evaporation loss.
- Not suitable in areas with high velocity Winds.
- Prohibitive cost of rain guns.
- Repairs by qualified personnel
