Sprinkler irrigation
- Install hand-move sprinkler irrigation systems with sprinkler heads on a 12 m × 12 m square grid.
- Mount sprinkler heads with two nozzles (4 mm × 3.2 mm), on 2.8 m higher risers, and maintain the operating mean pressure at 350 kPa with a flow rate of 1.47 m3 /h.
- Irrigation water is applied when soil water content reached approximately 60% of the total available water.
- Suitable
for all types of soil and is used mostly when the soil is too porous, uneven
and easily erodible.
