Tips To Understanding Pulse Irrigation

By Eliza Mendoza


As the world population grows, so does the need for food. Conversely, the arable land reduces with time. This calls for increased use of irrigation and other farming methods that utilize small spaces for maximum production. Pulse irrigation is a system that when used with other systems helps manage water while producing healthy crops hence more food.

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.

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.

This low flow pulse system can operate without monitoring for a long period of time. This saves the farmer from overwatering the plants. Engaging in this constant, frequent and controlled irrigation reduces water demand and lowers usage by a large margin. It also reduces water stress on plants as they have a period when there is no water flow as the pressure builds in the reservoir.

Basically, this system operates by the strong magnets that attaches to the outlet valve. These holds it closed as the pressure builds. When it is strong enough, the reservoir pressure forces the top magnets open. As the pressure reduces, it drops down thereby closing the valve again allowing the recharging to start.

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.

Pulse irrigation system has been proven to have many advantages in farming. Even when used with a drip or sprinkler system, you get no run offs on heavy soil. Used on sandy soil that is known to have poor water retention, there is no leaching or water loss. On hilly areas and shallow soil, water does not run off despite the terrain. One can also achieve temperature control effectively through evaporative cooling using foggers and sprinklers working intermittently. This low discharge rate allows for use of little space in greenhouse and smaller containers. The system installation costs are also lowered greatly since it requires low capacity water pumps and smaller conduits.
