Sprinklers for irrigation in Kenya by Aqua Hub are the most effective irrigation accessories. Sprinklers have multipurpose uses in several crops and farming models, and can offer effective production when properly installed and maintained.
It is important to understand the usage, requirements, models, and the way sprinklers work before choosing to try them.
How do Sprinklers work?
Sprinklers enhances moisture availability in the soil by supplying water in a rain pattern that wets in a rapid rate.
The mechanism that breaks water to jet raindrops is enhanced by self-generated centrifugal force of water. The force occurs when the water flow in delivery pipes hits the sprinkler head jets. The resulting effect is the rotation of the sprinkler head to release water from the nozzle in forms of swirling sprays.
Considerations When Choosing Sprinklers
Source of Water (Irrigation Water)
Sprinkler heads parts such as nozzles and spray heads are critical and needs a clean source of water to operate. They contain tiny holes that clog easily when dirty water is used. To avoid frequent inconveniences of clogging, always use clean water or install filters to trap dirt.
The water retention rate or permeability of the soil is necessary to consider.
The soil compactness also matters to ensure that soil prone to high erosion rate works with low pressure sprinklers.
Sprinkler irrigation works better with crops that cover a wide area (large growing crops). Since sprinklers release water at high pressure, smaller crops risk getting uprooted by water.
Crop height is another factor to bear in mind, as some sprinklers have a short height and distance per throw head.
Sprinkler irrigation is also unsuitable for some crops such as tomatoes, potatoes, and peppers due to the threat of fungal infections.
Flat lands are most ideal for sprinkler irrigation to avoid issues such as soil erosion. However, slightly sloping terrains are also possible to irrigate using sprinklers without adverse soil erosion occurring.
Classification of Sprinklers for irrigation in Kenya
- High pressure sprinklers – operate under high pressure to allow water to reach plants. They can be fixed or portable.
- Low Pressure sprinklers – they work under low pressure to deliver smooth sprays to plants.
Types of Sprinklers
- Impact sprinklers – high pressure sprinklers made of plastic rotary heads that release water through the nozzles. They can be fixed or portable.
- Rain Guns – Rain Guns are high pressure sprinklers made of brass or aluminium metals. They have a flange system with gear driven ability. They cover a radius of:
- Micro-sprinklers – Low pressure sprinklers mostly made of plastic materials. They supply water in low pressure sprays that are possible through nozzles or rotary plastic jets.
Applications of Sprinklers for irrigation in Kenya
- Irrigation of gardens, greenhouses, and orchards.
- Fixed and rotating sprinklers, for irrigating vegetables, nurseries, and sub-canopies in fruit growing.
- Rain Guns for irrigation of cereal plantations such as sugar cane and orchards.
- Pop-up sprinklers for Irrigation of lawns, gardens, and grasses.
