Motives 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.

The pulsing equipment contains two orifices that are cross-sectional: one that is smaller and one that is larger (inlet and outlet). There is also a valve that works automatically and the various pressure levels can make it close or open. For storing the liquid, you can take advantage of the system reservoir. At the moment in which the valve closes, the container becomes full and it opens the valve because of the pressure that is created.

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.

According to the twenty minutes rule, in one hundred and eighty minutes you could make three watering cycles with an application rate of four millimeters per hour. One of the reasons for using a system is saving money, because the irrigation is not made without a stop. In the society and economic conditions of today, farmers see pulse applications as efficient ways of feeding crops. Watering and fertilization are usually the most costly procedures in the entire lifetime of a culture.

The entire cost of farming cab become lower if just one of the two components is cheaper. Pulse irrigation is not a classical mean and it is highly adaptive to a plant needs for nutrients. One of the reliable watering schedules could be ten or fifteen minutes each hour, for six or twelve hours daily.

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.

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.
