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 ...
In China, they were also called dragon backbones. [8] One of the earliest accounts was a description by the Han dynasty philosopher Wang Chong (A.D. 27–97) around A.D. 80. [9] Unlike those found in the West, chain pumps in China resembled the square-pallet type instead of the pear-shaped bucket [dubious – discuss]. Illustrations of such ...
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.
The imbalance between supply and demand, along with persisting issues such as climate change and population growth, has made water reuse a necessary method for conserving water. [37] There are a variety of methods used in the treatment of waste water to ensure that it is safe to use for irrigation of food crops and/or drinking water.
The water is applied rapidly to the entire basin and is allowed to infiltrate. In traditional basins no water is permitted to drain from the field once it is irrigated. Basin irrigation is favored in soils with relatively low infiltration rates. [1] This is also a method of surface irrigation.
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
It is a method of controlled and intermittent irrigation. A periodic drying and re-flooding irrigation scheduling approach is followed in which the fields are allowed to dry for few days before re-irrigation, without stressing the plants. This method reduces water demand for irrigation and greenhouse gas emissions without reducing crop yields.
A taanka or paar, is a traditional rainwater harvesting technique, common to the Thar desert region of Rajasthan, India. [1] It is meant to provide drinking water and water security for a family or a small group of families. A taanka is composed of a covered, underground, impermeable cistern on shallow ground for the collection of rainwater.
