Drip irrigation or trickle irrigation is a type of micro-irrigation system that has the potential to save water and nutrients by allowing water to drip slowly to the roots of plants, either from above the soil surface or buried below the surface.
Irrigation is the artificial exploitation and distribution of water at project level aiming at application of water at field level to agricultural crops [1] in dry areas or in periods of scarce rainfall to assure or improve crop production. [2] This article discusses organizational forms and means of management of irrigation water at project level.
Drip irrigation layout and its parts. Drip irrigation, also known as microirrigation or trickle irrigation, functions as its name suggests. In this system, water is delivered at or near the root zone of plants, one drop at a time. This method can be the most water-efficient method of irrigation, [26] if managed properly; evaporation
Using drip irrigation methods can save up to 30,000 gallons of water per year when replacing irrigation systems that spray in all directions. [34] There are also cheap effective methods similar to drip irrigation such as the use of soaking hoses that can even be submerged in the growing medium to eliminate evaporation.
Irrigation scheduling is the process used by irrigation system managers to determine the correct frequency and duration of watering. The following factors may be taken into consideration: Precipitation rate of the irrigation equipment – how quickly the water is applied, often expressed in inches or mm per hour.
Spate irrigation (from the English word spate, meaning: a. a flood or inundation. b. a river flooding its banks) uses seasonal floods of rivers, streams, ponds and lakes to fill water storage basins. It is an ancient method of irrigation in arid and semi-arid climates in the Middle East, North Africa, West Asia, East Africa and parts of Latin ...
A satellite image of circular fields characteristic of center pivot irrigation, Kansas Farmland with circular pivot irrigation. Center-pivot irrigation (sometimes called central pivot irrigation), also called water-wheel and circle irrigation, is a method of crop irrigation in which equipment rotates around a pivot and crops are watered with sprinklers.
They can save much irrigation water. [5] A checked drainage system also reduces the discharge through the main drainage system, thereby reducing construction costs. When the discharge takes place by pumping, the drainage can be checked simply by not operating the pumps or by reducing the pumping time.
