Drip Irrigation for Vegetables
Drip (trickle) irrigation was pioneered in the 1940s in England, but not until the advent of polyethylene plastics in the 1960s did field application of this efficient watering method become widespread. Drip irrigation is a method of applying small amounts of water, often on a daily basis, to the plant’s root zone. A drip irrigation system has four major components and two options.
- Delivery system: emitters or line source drip tubing
- Filters: sand, disk, or screen
- Pressure regulators: spring or valve
- Valves: hand-operated, hydraulic, or electrical
