In drip irrigation, water is run through pipes (with holes in them) either buried or lying slightly above the ground next to the crops. Water slowly drips onto the crop roots and stems.
How drip irrigation is done?
With drip irrigation, water is conveyed under pressure through a pipe system to the fields, where it drips slowly onto the soil through emitters or drippers, which are located close to the plants. It is applicable to almost every crop prediction, especially in arid, dry areas.
What are the main components of drip irrigation?

How does drip irrigation work in agriculture?
Drip irrigation reduces water contact with crop leaves, stems, and fruit. … Agricultural chemicals can be applied more efficiently with drip irrigation. Since only the crop root zone is irrigated, nitrogen already in the soil is less subject to leaching losses, and applied fertilizer N can be used more efficiently.What is drip irrigation PDF?
In drip irrigation, water is applied to each plant separately in small, frequent, precise quantities through dripper emitters. … The water is delivered continuously in drops at the same point and moves into the soil and wets the root zone vertically by gravity and laterally by capillary action.
How do drip irrigation valves work?
Drip irrigation valves are designed to be used with a timer to automate an irrigation system.
