What is a basin irrigation?
Basin Irrigation. Another form of surface irrigation is called basin irrigation (Figure 3a), in which water floods a smaller area or basin surrounded by raised berms, usually made from earth.
How did basin irrigation work?
Basin irrigation A crisscross network of earthen walls was formed in a field of crops that would be flooded by the river. When the floods came, the water would be trapped in the basins formed by the walls.
What is advantage of basin irrigation?
Advantages/Benefits/Pros: It has good control on irrigation water and high water application efficiency. Though the Initial cost is high, it requires less labour and has low maintenance cost. Wastage of water and soil erosion is reduced as there is bund around the basin.
What is Basin farming?
Permanent Planting Basins, as used in conserva- tion farming, is a crop production method which enhances the capture and storage of rainwater and allows precision application and utilization of limited plant nutrients. The method is widely used to reduce risk of crop failure due to unreliable rainfall.
Which crops are grown in basin irrigation?
Basin irrigation is generally not suited to crops which cannot stand in wet or waterlogged conditions for periods longer than 24 hours. These are usually root and tuber crops such as potatoes, cassava, beet and carrots which require loose, well-drained soils.
What is sub irrigation system?
In agricultural production fields, subirrigation is an irrigation practice to control the water table at certain levels by elevating or lowering it. This is accomplished by artificial- ly adding water to the soil profile underground to moisten the crop root- zone for a determined period.
Which crops are suitable for basin irrigation?
Basin irrigation is suitable for use on moderate to slow intake soils and deep-rooted, closely spaced crops such as maize, grains, cotton, or orchards. Crops that do not tolerate flooding and soils subject to crusting can be basin irrigated by furrowing or using raised bed planting.
How a basin is formed?
Basins are formed by forces above the ground (like erosion) or below the ground (like earthquakes). They can be created over thousands of years or almost overnight. The major types of basins are river drainage basins, structural basins, and ocean basins.
Why are basins important?
Basins are vital to human existence, since they provide clean water for drinking; water for growing food; and water to nourish plant life, which provides the oxygen people breathe. Historically, basins were also an important factor in determining geopolitical borders.
Where is basin irrigation used?
Basin irrigation is suitable for many field crops. Paddy rice grows best when its roots are submerged in water and so basin irrigation is the best method to use for this crop (Figure 7).
Where is sub-irrigation used?
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.
