What is a rain hose irrigation system?
Rain hose irrigation systems are a new way of watering crops intensely under moderate pressure. Each kit has a 100M long pipe as the main accessory. The pipe is sequentially perforated at determined intervals using Nano technology to create tiny holes from which crops are irrigated. Other components of the kit are
- End caps
- Starter off takes
- Pipe connectors
The diameter of the pipe ranges from 32mm to 50mm. A grower chooses the preferred size based on crop water needs and area of irrigation. For instance, a farmer with 1 acre of crop will comfortably water with the volume delivered through a 32mm rain hose pipe. Another grower with 5 acres will better irrigate with a 50mm rain hose pipe. An acre of crop uses 800 meters of 32mm rain hose pipes, 600M of 40mm pipes and 400M of 50mm pipes.
Rain hose irrigation system requirements
The system requires a pressure head of 30M. The rate of water discharge is determined by the diameter size. It irrigates in opposite directions at a radius of 3M for the 32mm pipe, 5M for the 40mm pipe and 7M for the 50mm pipe. The height of this water jet is 1M. Rain hose irrigation systems are used in the following area and on these crops.
- Crop nurseries; vegetables, fruit, forestry
- Short vegetable crops (knee high and below); cabbage, lettuce, broccoli, kales, spinach, collards, broad beans, carrot, strawberry and others
- Pasture; grass and legumes
When choosing the crop to irrigate using this method, consider its susceptibility to foliage fungal infections predisposed by leaf surface wetness. Tomato, potato, peppers, peas, green beans and chilli easily succumb to foliage fungal infections when overhead or rain hose irrigation methods are used for a long time.
