Impact sprinklers are overhead irrigation accessories that water crop under moderate to high pressure. The moderate pressure power force is by gravity, and the higher pressure is from a water pump. Grekkon Limited installs and supplies these sprinklers in various inlet pipe diameter sizes as; 1/2 inch, 3/4 inch and 1 inch. Beyond these sizes, we supply the more powerful rain gun generation of sprinklers. The nozzle diameter size of the sprinklers is 0.4mm, 0.6mm and 0.8mm respectively for 1/2 inch, 3/4 inch and 1inch.
Because of their short irrigation diameter and low water discharge volume, impact sprinklers are designed for small farms and short crops. During installation, plastic PVC and HDPE, canvas delivery or metallic GI pipes drive water to the sprinkler from a source. The choice between a plastic one and a metallic sprinkler is on the farmer’s budget. The latter has a longer usable lifespan, is susceptible to damage but costs more. Plastic versions are easier to handle, carry and operate. They cost less but are easily damaged and so have a shorter usable lifespan.
How to use impact sprinklers
During irrigation, consider crops that are not susceptible to foliage fungal infections as a result of wetness on their leaves. Drip irrigate for tomato, peppers, potato, chili and other solanacious crops. This is to avoid excess moisture on their leaves because they quickly succumb to leaf fungal infections as a result of wetness. Certain bean types, snow-peas and mangetout too will easily get leaf fungal infections under sprinklers.
Common food crops such as; onion, cabbage, grass and legume pastures. Others are; garlic, carrot, maize, lettuce, broccoli, cauliflower, watermelon, orchards, forestry crops. Many others will be fine under this irrigation system.
Grekkon Limited’s irrigation technicians and agronomists provide guidance on system use and crop selection for this irrigation system.
