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.
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.
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.
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 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.
