Reasons For Using Pulse Irrigation

By Teri Farley


Pulse irrigation uses pressurized water that is supplied continuously, but has a pulsating output. Very small amounts of effluent is applied, using a low rate system. According to research, once the soil moisture level increases, lower effluent levels do not lead to loss of nutrients. The discharged liquid can be used to manage the amount of moisture available for the plants.

The device that pulses has two cross-sectional orifices: a small one(inlet) and a larger one(outlet). The system also contains a valve that opens and closes automatically because of differences of pressure. In order to store water, a reservoir is used. The storage container fill up when the valve is closed and also creates pressure for opening it.

Nutrients must be maintained in the root area for allowing plants to feed and the application of effluents is made according to this. The cultures receive the nourishment, because there are no leaks into the ground. The deficit of soil moisture can become lower in most cases. The classical irrigation method, in which an individual makes the watering must not be mixed with a pulse system, for avoiding nutrient loss in the root area.

It does not matter if the soil moisture reaches field capacity, as pulse irrigation can still be used. A good control of effluent can exist, regardless of the facts that soil can be very humid, or completely dry and cracked. The nutrients are kept exactly in the needed spots. Specialists say that an efficient cycle should have twenty minutes of pulsing and forty minutes in which the system is on hold.

As the twenty minute rule is applied, a system can go through three watering cycles during one hundred and eighty minutes. Four millimeters are covered each hour. Many people use the procedure because it can help them save money. The automated system ensures a continuous irrigation of crops. Today, when economic conditions can be harsh, pulse applications may be very efficient ways of providing nutrients to the plants in a culture. In general, fertilization and watering are the most expensive elements of farming.

If at least one of the two costly procedures can become cheaper, the whole cost of farming could be reduced. Pulse irrigation is a nontraditional process and it can adapt nicely to the moisture and feeding requirements of a plant. A good schedule for watering can be ten to fifteen minutes every sixty minutes, for six or twelves hours each day.

The tools required for the right procedure can be: solenoid valves at each needed area, an irrigation controller and underground cables for linking the two components. Soils moisture levels have been measured by scientists prior to using the system and after. In the tests, plants like blueberries, blackberries and tomatoes were used.

As a modern way of watering plants pulse irrigation can become very popular today, because of lowering farming costs. A system can work on its own and the liquid is sprayed in cycles, for adapting to the requirements of a culture. Agriculture can be greatly improved, as the management of crops may be optimized.
