Sprinkler jet micro sprinklers by Grekkon Limited are low-pressure, low to medium volume irrigation equipment. Micro sprinklers are used for; fruit tree, lawn, hedge, and small garden irrigation. Micro sprinklers save water through high application efficiency, and uniformity of spray. They are a substitute for button drippers where drip irrigation is impractical, but create a larger wetted area than drip irrigation. Micro sprinkler irrigation provides low precipitation which allows for longer watering time with low run-off. They are available in a wide range of plastic configurations. Micro sprinkler sets are used with fertigation systems which save on fertiliser application labour cost. They are also light in weight and small in size, which make them highly portable , and easy to install
What is micro sprinkler irrigation?
It is crop watering through the use of sprinkler jet micro sprinklers
Sprinkler Jet Micro Sprinklers Coverage
Micro sprinklers covearge is a factor of; flow rate, wetting diameter or radius, and the wetting degree.
1. Operating pressure; from 15M head / 1.5 bar. Pressure lower than this will cause the micro sprinkler to release large droplets. These droplets will be unhelpful, or even destructive to the work untaken
2. Flow rate 55- 110 litres per hour
3. Irrigation degree; available as 90, 180, and 360 degrees
4. Irrigation radius; 1.5M to 3.5M. This is an important factor to note during installation because it guides on the spacing of one sprinkler jet micro sprinkler to another
Micro sprinklers work when positioned upright, or upside down. Upright when they’re standing on the ground for normal irrigation. Upside down when set in a greenhouse, or open field crop to provide humidity to a mature crop or seedlings. This upside down placement is also for keeping plant foliage moist, or for overhead irrigation.
They deliver irrigation water through micro tubing to a series of nozzles attached to risers. They have small to medium sized droplets with good uniformity of coverage, and lower precipitation rate.
How to space micro sprinklers
Micro sprinklers placement is in such a manner that the sprays overlap. If for instance the irrigation diameter is radius is 1.5M, the distance between micro sprinklers will be 2.25M. This ensures that there are no dry spots in between. An overlap ensures full coverage particularly for lawns, hedges or very closely spaced crops
How to use micro sprinklers with fruit trees
Set one micro sprinkler per tree, 30cm or 1 foot from the base of the tree trunk being irrigated. Unlike online or button drippers which work well with gravity, a water pump will be necessary when irrigating with many micro sprinklers.
How much is micro sprinkler irrigation?
The unit cost of all types of sprinkler jet micro sprinklers at Grekkon Limited is from Kes 150 at any of our branches nationwide. Micro sprinker price per acre is a factor of the number of units used, which depends on the crop spacing. For instance tree tomato spaced at 2M x 2M will require a higher number of micro sprinklers than avocado spaced at 6M x 5M
How much water do micro sprinklers use?
They use a maximum of 110 litres per hour
