Surface Irrigation involves distributing water over the surface of the soil
Sprinkler Irrigation involves use of pressurized nozzles to spray water in a shower
Variable flow irrigation involves use of advanced version of sprinkler irrigation
Trickle Irrigation involves use of emitters to control the flow of water
Sub-irrigation involves the use of perforated pipes
Explanation:
Surface Irrigation involves distributing water over the surface of the soil by allowing water to flow into the farm from irrigation channels.
Sprinkler Irrigation involves use of pressurized nozzles to spray water in a shower on the plants.
Variable flow irrigation involves use of advanced version of sprinkler irrigation. It has a variable-flow control knob on it to vary the output and flow of water. It also ensures uniform water distribution.
Trickle Irrigation involves dripping water onto the soil at very low rates through a system of tiny pipes fitted with outlets called emitters or drippers in order to control the flow of water.
Sub-irrigation involves the use of perforated pipes to apply water below the soil surface in order to raise the water-table near the plant root zone as well as to remove excess water.
