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.

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.

Effluent must be applied in a way the will permit the nutrients in the soil to stay in the root zone, for feeding the plants. Instead of leaking into the ground, the liquid feeds the cultures. In many cases, the soil moisture deficit decreases. The old way of irrigation that involves traveling along the required areas should not be combined with the automated one, as it can cause loss of nutrients in the root zone.

Pulse irrigation can be used continuously even until the moisture level for the soil is near the field capacity. Effluent can be managed when soil humidity is at high levels, but also when the area is dry and cracked, as this will keep nutrients where they are needed. Experts recommend that the cycle should have twenty minutes of watering, followed by forty minutes of of pause.

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.

You can decrease the the natural nutritional schedule of a plant. If you want to water crops efficiently, it must be done ten to fifteen minutes an hour. The process must be repeated each day, for six hours, or twelve.

The equipment needed for a correct operation can include an irrigation controller, solenoid valves at every required location and underground wires that could connect the two devices. Researchers have measured soil moisture levels before and after using the method for testing purposes. Cultures of tomatoes, blueberries and blackberries have been used for the studies.

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.
