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 is a type of irrigation that makes it possible to manage your water usage. It can be scaled to whatever flow one requires so as to greatly minimize water flow. It can be used with sprinkler or drip irrigation very effectively. The traditional low flow systems and even ultra low flow systems of irrigation can be used with this pulse system.
It is even better used in places with scarcity of water like in desert regions. By passively allowing water to flow into a reservoir, it builds pressure at a controlled rate. Once the predetermined pressure is reached, the outlet valves are forced open hence a pulse of water flows out.
As the reservoir pressure reduces, the valves close giving the reservoir time to recharge. As long as the inlet is kept lower than outlet, the cycle of recharge and discharge will be kept going. A drip flow controller is used in this system to regulate the water flow rate into the reservoir.
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.
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.
The advantages of using this pulse irrigation system are numerous. When used for drip and sprinkler systems, there are no run off on if using heavy soil. In sandy soil, you have no leaching and water is not lost even though sand has low water retention capabilities. In hilly areas and shallow soil, water can still be applied efficiently without any run off. Temperature control can be achieved through evaporative cooling by use of the intermittent sprinkling and use of foggers. Given the very low discharge rate, growing plants in containers or greenhouse will require less space. It allows for the use of lower capacity pumps and smaller conduits hence reduced system costs in general.
