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.

Décider de sélectionner une technique d’irrigation ou de passer à une technique plus efficiente est compliqué. D’un point de vue de la préservation de l’eau, le choix est simple, les économies en eaux augmentent lorsque l’on passe de l’irrigation de surface à l’aspersion et de l’aspersion à la micro irrigation.

Cependant, le succès d’une technique d’irrigation sera très dépendant du site, de facteurs de situation ainsi que du niveau de gestion utilisé.
