Intermittent irrigation

The pulse 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 every so often. For example, an irrigation cycle may consist of watering for ten minutes and keeping the water closed for five minutes. In addition, it can be said 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 left 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 disaggregation of the soil aggregates that favors the reordering of the substrate layers and a migration of sediments that causes an isolation of the surface and the water of the next cycle advances more quickly over the wet soil.
