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.
Used together with drip or even sprinkler systems, this system makes it possible to manage water usage effectively. It is scalable to whatever level one desires for maximum water saving features. It is applicable also with the low flow systems and the ultra low flow systems of irrigation.
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.
Once the pressure reduces in the reservoir, the valves close allowing pressure to recharge again. As long as the inlet flow is lower than the outlet, the recharge and discharge cycle will continue. For this to work, a drip flow controller is used at the inlet to control rate of water flow into the reservoir.
As long as the system is properly installed, it will not need any monitoring. This system keeps the plants from overwatering. This constant, controlled and frequent water flow reduces the plant demand for water and lowers usage of water. The plants also do not experience water stress due to the intermittent supply.
To make this system work, strong magnets are used to keep the outlet valve closed. As the reservoir pressure overcomes the magnet strength, they are forced open and the top one goes up allowing water to flow. When the pressure reduces, the magnet lowers and sticks back in position and another cycle of recharging starts.
Using this on a sprinkler system is very effective for open farming. When seeds are germinating, one can use a frequency of 5 second sprinkling every minute for the first 2 weeks. This can then be adjusted to 8 hours sprinkling three times a week. This frequency is determined by plant water need, weather condition and the strength of the sun in that season.
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.
