Top Reasons Why Farmers That Use Sprinkler Systems Succeed

The ultimate challenge in crop irrigation management is to obtain system’s efficiency and uniform water application while securing natural resources, which is water and soil. As a matter of fact, there are no similar sprinkler irrigation systems; some may be more efficient and some are less. Nonetheless, the efficiency totally depends on the conditions in which irrigation systems are installed like the type of soil and crop, slope and field size, and the weather conditions in the given location as well.  

 Sprinkler Systems

When help is needed farmers should be quick to call a qualified sprinkler service company to resolve any problems.   

What Consists a Sprinkler Irrigation System? 

All sprinkler irrigation system makes up the following components: 

  • Control head – It maintains pressure and water demand in the system.
  • Primary and sub-primary lines – They are temporary or permanent pipes that deliver water from the source to the laterals.
  • Pumping source – It is a centrifugal pump that takes water and gives enough pressure in order to deliver adequate water into the pipe system.
  • Accessories – They can be risers, couplers, valves and pressure regulators.
  • Sprinklers or emitters – They are devices that supply water through the soil or the air and deliver it to the crops.
  • Laterals – They are portable pipes that distribute water from the primary or sub-primary lines to the sprinklers.

The primary goal of the sprinkler irrigation system is to apply uniform water distribution to crop root zones. Therefore, the farmer has to pay good attention to 3 factors in order for the irrigation management to succeed. 

The 3 factors are the emitter drop size, application rate and wetting patterns that all differ on the operational performance and the sprinkler type. 

 Wetting Pattern 

Irrigation Sprinkler system run under certain pressure of water and display a wetting pattern. In order to obtain uniform wetting pattern on crop root zone, lots of sprinklers should be installed together so that their patterns overlap. Having said that, the overlap must be 65% at least of the wetted diameter. Also, this determines the utmost spacing between the sprinklers. There are added factors that affect the operation of sprinklers like wind conditions, soil intake rate, water quality, flow-rate and crop spacing.  

 Application Rate 

It is the usual rate at which the water is provided to the crops. However, it mostly depends on the distance between sprinklers, the operating pressure and the sprinkler nozzle size.  

It plays a very important part in selecting of the sprinkler irrigation system. The normal water application rate must be lesser than the normal soil infiltration rate or else, the soil would not absorb the applied water, thus, runoff will occur.  

Emitter (Sprinkler) Drop Size 

As water sprinkles from the emitter, it breaks into very tiny drops. This drop size is being controlled by nozzle type and pressure. Larger drops are created by low pressure which affect soil and crops. Also, nozzle type determines the water distribution pattern and flow-rate.
