They result from a combination of soil type and rooting depth. Border irrigation is particularly suitable for close growing crops such as alfalfa, but border irrigation can also be used for row crops and trees.
Furrow irrigation is best used for irrigating row crops such as maize, vegetables and trees. The equipment needed is often easier to maintain and less dependent on the availability of foreign currency. With this inclination it is possible to irrigate the whole strip of 15 m width.
In heavy soils water absorption rates are low. This is practiced in the vineyards at Lanzarote using stones to condense water. When the slope is steeper, special arrangement is made to prevent erosion of soil. One useful feature of a lateral move system is that it consists of sections that can be easily disconnected, adapting to field shape as the line is moved.
There is no erosion of soil. The applied water is retained in the basin until it filtrates. This can happen where there is overdevelopment of hydraulic infrastructure, usually for irrigation.
Sprinkler and drip irrigation, because of their high capital investment per hectare, are mostly used for high value cash crops, such as vegetables and fruit trees. A landscape irrigation system may also include zones containing drip irrigation, bubblers, or other types of equipment besides sprinklers.
It is best adopted for heavy soils also. Perforated Fixed Pipe Sprinklers: These systems are found and used in all parts of the world and allow irrigation of all types of terrain.
The maintenance - ploughing and furrowing - is also often done by machines.
Sections of the landscape will usually be divided by microclimatetype of plant material, and type of irrigation equipment. Although manual systems are still used, most lawn sprinkler systems may be operated automatically using an irrigation controllersometimes called a clock or timer.
Flooding method of irrigation is in use since centuries. Symptoms of economic water scarcity include a lack of infrastructure, with people often having to fetch water from rivers for domestic and agricultural uses.METHODS OF IRRIGATION.
Several methods of irrigation are used today depending on water availability, the type of irrigated crop and the financial investment the grower is willing to make. A firm knowledge regarding the irrigation techniques available can help one understand the different types of deficit irrigation.
Methods of Irrigation 1. Methods of Irrigation 2. IRRIGATION METHODS or Modes of Application of Water to Crops There are various ways in which the irrigation water can be applied to the fields. ADVERTISEMENTS: Read this article to learn about the important methods of irrigation, i.e., (1) Surface Irrigation (2) Overhead or Sprinkler Irrigation (3) Drip or Trickle Irrigation.
1. Surface Irrigation: In this method water flows and spreads over the surface of the land. Surface irrigation consists of a broad class of irrigation methods in which water is distributed over the soil surface by gravity flow. The irrigation water is introduced into level or graded furrows or basins, using siphons, gated pipe, or turnout structures, and is allowed to advance across the field.
To choose an irrigation method, the farmer must know the advantages and disadvantages of the various methods.
He or she must know which method suits the local conditions best. Unfortunately, in many cases there is no single best solution: all methods.
3. METHODS OF IRRIGATION Irrigation water can be applied to crop lands using one of the following irrigation methods: (i)Surface irrigation (a.Download
