Motives 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.

There are two cross-sectional orifices involved in a pulsing device: an inlet one (small) and an outlet one (larger). A valve also exists, which can open or close automatically when pressure levels change. The liquid is deposited in a reservoir. Just as the valves closes, the recipient can become full and this can lead to an opening.

The nutritive substances have to be kept in the root zone. Plants must extract the compounds and effluents are applied according to this stage. Since no underground leaks exist, the nourishment can begin. In the majority of cases, soil humidity deficit levels can decrease. The traditional manual irrigation way that involves a person should not be combined with the modern one. Loss of nutrients can occur if the rule is not respected.

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.
