En revanche l’utilisation de ce type de pompe ne permet pas un arrosage par aspersion ou par « goutte à goutte », mais l’irrigation gravitaire est envisageable. Ce type d'irrigation, ayant une charge de 0,4 à 1 m, convient pour un sol relativement plat. Fig2. mainly the efficiency of this method of irrigation depends on type of soil and crop, etc. 2.6 million km 2 are utilized. Nous contacter. Surface irrigation is the application of water by gravity flow to the surface of the field. Either the entire field is flooded (basin irrigation) or the water is fed into small channels (furrows) or strips of land (borders). It is widely utilised and therefore a well-known system, which can be operated without any high-tech applications. S'identifier.

Les techniques d’irrigation agricole sont des méthodes pour apporter de l’eau aux cultures et sont classifiées en irrigation de surface, irrigation par aspersion et micro irrigation. Surface irrigation: Surface irrigation is mainly used in field crops and orchards. Irrigation qui projette l’eau en l’air pour tomber à la surface du sol sous forme de fines gouttelettes). Surface irrigation (flood irrigation): It is most common form of irrigation where water is applied and distributed over the soil surface by gravity. It needs a good effort. Surface irrigation is mainly divided in basin, border, and furrow systems. Irrigation par aspersion. In this methods gravity is used to supply the water from source of irrigation to the crop with the help of canals, pipes, etc. Types of Surface Irrigation: There are three main types of surface irrigation as given below; Basin Irrigation; Furrow Irrigation; Border Irrigation; Basin Irrigation: In small areas that have a level surface, basin irrigation has been used and by earth banks, these level surfaces should have to be surrounded.
