With the increasing need for food and reduction in arable pieces of land, the use of irrigation farming is increasing. We have many types of irrigation systems available depending on need and budget of the farmer. Among these is pulse irrigation.
This system makes it possible to effectively manage your water resources. Since it is scalable, one can set it whatever way desired for the minimal water usage. Used with a drip or sprinkler system, the irrigation will be well managed. It can also be used together with the usual low flow systems and the ultra low flow systems.
This is an irrigation system mostly used in areas where water is very scarce like in desert countries including Israel. It works by passively allowing water to flow at a controlled rate into a reservoir so as to build pressure in the reservoir at a steady rate. On reaching a predetermined pressure level, the valves from the reservoir open forcing a pulse of water out.
The flow gradually lowers the pressure hence the valve closes again so that the reservoir can recharge again. The inflow is kept below the outlet flow therefore the cycle is maintained. A drip flow controller is used at the inlet managing the rate at which water flows into the reservoir therefore the timing.
Once set, this system can operate without any other input for long periods of time. This constant and frequent irrigation helps reduce water demand by the plant while also lowering water usage very efficiently. The plants are also protected from water stress due to the intermittent water supply to the soil.
The outlet valve has strong magnets holding it closed as the pressure builds. When the pressure in the reservoir is strong enough, it overcomes the strength of the magnets forcing the top set of the magnets to open. A reduction in pressure allows the magnet to drop down and the recharging phase begins again and the cycle goes on and on.
When used with a sprinkler system, the results are impressive. During seed germination, it can be set to sprinkle for 5 seconds every minute in the first two weeks after planting. This is then gradually adjusted till you can allow it to sprinkle for an 8 hour period three times a week. The basic determinants are the rain conditions, intensity of the sun and water need by the plant.
This pulse irrigation system has numerous advantages. Used with a sprinkler or even drip irrigation system, it has no run offs. Used o sandy soil, there is no chance for leaching or water loss in the loose soil. When used on hilly areas and on shallow soil, water does not run off. In order to achieve temperature control, use intermittent sprinkling and foggers to perform evaporative cooling I hot conditions. The system also allows for the use of less space in greenhouses and containers. Lower capacity pumps and smaller conduits can be used therefore reducing installation costs.
