Intermittent irrigation

The impulse irrigation system, also called discontinuous or intermittent, consists of applying water to the furrows in short but frequent time intervals, in the same irrigation period. This is achieved with a device that opens and closes the water outlets in the irrigation systems from time to time. For example, a watering cycle may consist of watering for ten minutes and keeping the water off for five minutes. Furthermore, it can be indicated that intermittent irrigation uses a natural effect that all soils have to a greater or lesser extent. Once the soil is wet, the water is removed and allowed to rest for a short time. In this way, the water travels through the soil in several discontinuous cycles. The explanation of the phenomenon in this irrigation technique is due to the fact that between one cycle and another there is a disintegration of the soil aggregates that favors the rearrangement of the substrate layers and a migration of sediments that causes an isolation of the surface and the Water from the next cycle moves more quickly over the moist soil.
