Coil irrigation
Serpentine or zigzag irrigation are grooves made in the ground to provide controlled (directed) flow of water below the surface of the crop. The type of furrow will depend on the slope of the land: if it is low in slope, linear furrows are used, but if there are relatively steep slopes, an option to use are “S” shaped furrows or ditches, which are also used on low slopes, in order to have greater control over the conduction of irrigation water.
