Subirrigation

Subirrigation is a type of irrigation where water is distributed through underground pipes. In this type of irrigation, the water comes out through special openings and goes back into the ground by infiltration and capillarity, reaching the roots of the plants.

Subirrigation has the advantage of not hindering the surface tillage of the soil and of not causing losses of water by evaporation; on the other hand, it has a high planting cost and hinders deep plowing. In practice, it is convenient in the presence of valuable crops and soils with poorly permeable subsoil.
