Subirrigation also known as seepage irrigation, is a method of irrigation where water is delivered to the plant root zone. The excess may be collected for reuse. Subirrigation is used in growing field crops such as tomatoes, peppers, and sugar cane in areas with high water tables such as Florida and in commercial greenhouse operations.
Drip irrigation systems distribute water through a network of valves, pipes, tubing, and emitters. Depending on how well designed, installed, maintained, and operated it is, a drip irrigation system can be more efficient than other types of irrigation systems, such as surface irrigation or sprinkler irrigation.
Micro-irrigation, sometimes called localized irrigation, low volume irrigation, or trickle irrigation is a system where water is distributed under low pressure through a piped network, in a pre-determined pattern, and applied as a small discharge to each plant or adjacent to it. Traditional drip irrigation use individual emitters, subsurface ...
Irrigation water has a price by which the management costs must be covered. The following tariff (water charge) systems exist: [6] No tariff, the government assumes the costs; Tariff in labor hours, which holds mainly in communal types of management in traditional irrigation systems; Yearly area tariff, a fixed price per ha per year
Most automatic irrigation valves are diaphragm valves in which the water above the diaphragm must be discharged for the valve to open. In a hydraulic system, the controller and valves are connected via small plastic tubes approximately 4 mm (¼ in) in diameter. The controller opens the tube connected to the valve, allowing that valve to open.
An irrigation sprinkler (also known as a water sprinkler or simply a sprinkler) is a device used to irrigate (water) agricultural crops, lawns, landscapes, golf courses, and other areas. They are also used for cooling and for the control of airborne dust.
Greenhouses and conservatories are similar in function but are larger and heated with an external energy source. They can be built out of glass but are now primarily made from plastic sheets. More expensive and modern greenhouses can include temperature control through shade and light control or air-conditioning and automatic watering.
An irrigation controller is used with automatic systems and may be needed for back flushing the filter or sand separator. Since water conservation is a main reason for choosing micro-irrigation systems, soil moisture sensors, rain shutoff sensors and sometimes even weather stations may be installed to further reduce consumption.
