After having poor results with pulse irrigation, several Peruvian farmers chose the capillary irrigation concept from the Wise Irrisystem Company. Pulse irrigation is a variation of conventional irrigation that fractions water provisions during the day without controlling, the physical-chemical variables of the environment.
The first period of the crop plant developed better with this method of irrigation than with conventional irrigation, but, as the crop progressed, the effects of salinity (salts that are concentrated in the surface soil) were noticeable and, the more conductivity the water had in origin, the faster the salinization process was.
There was a reduction in crops that used pulse irrigation due to soil salinization.
The Wise concept of irrigation differs radically since it is a capillary and controlled irrigation that responds to the demand of the plant, by watering it shortly, in what is often referred to as pulses. Under this concept there is no accumulation of salts, that is to say, soil salinity is prevented.
Dr. Eitan Israeli, Wise agronomist, has concluded that pulse irrigation, without taking into account other fundamental physical and chemical aspects, such as the movement of nitrates, among others, can lead to good short term results but in the medium long term, causes uncontrolled movement of salts and fertilizer residues in irrigation, which create soil salinity and destroy crops.
Pulse irrigation without adequate control was applied in Chile causing the loss of 1 million hectares.
Dr. Eitan said that, "the basis of the concept of capillary watering is the precise control of the first soil horizon. It is true that you can get good results in the first year or two imitating a model of high frequency irrigation; but the most dangerous thing happens in the second and third soil horizon, when the accumulation of salts will surface, preventing the use of that land. "
Recently, Wise Irrisystem's technical team has travelled to Peru, in order to meet the growing demand from local producers of grapes, avocado and asparagus for the implementation of the Wise concept.
