Reasons For Using Pulse Irrigation

By Teri Farley


People can use pressurized water to spray crops continuously and without their intervention, through pulse irrigation. A small quantity of effluent could be offered to the plants with the use of a low rate system. According to experts in the field, nutrients can be maintained even if a small amount of effluent is used, or there is an increase of the moisture level. The discharged water may be used in a way that allows a good ground humidity management.

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.

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.

Even if soil humidity reaches the limit, pulse irrigation can still be implemented. Ground moisture does not affect the management of effluent, as it can work well on dry and cracked surfaces too. The nutritive substances can be held in the required locations. According to studies, for making a cycle efficient, the pulsing time has to be of twenty minutes, with pauses of forty in between.

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 proper operation can be ensured by components like: an irrigation controller, solenoid vales for all areas in which they are required can buried cables for making connection between the devices. Researchers have tested the level of humidity before an operation and after it. Blackberries, blueberries and tomatoes were the subject of the measurements.

Pulse irrigation is a new trend in watering crops and it can decrease agriculture costs. The automatic functioning ensures a spraying of water in cycles, which is meant for fitting the natural requirements of a plant. A great improvement could be seen for farms when the concept is used. Cultures can be optimized for maximizing production levels.
