Configurations Of Farm Irrigation Systems

By Joseph Reynolds


Farming in modern times has developed a set of techniques for providing needed moisture to the crops. There are several that are available in order to accommodate several different types of landscaping and needs. Certain crops need certain types of farm irrigation systems in order to maximize growth potential in the ever increasing competitive global agriculture market. Choosing the right system depends on the crop and the type of land it is growing in.

Surface irrigation is designed to be set up in any place where gravity can do the job. This is a process that has been in use for thousands of years and requires no mechanical pump to feed water to the crops. Channels are placed between the rows and water is sent through using gravity from a slight slope. It is one of the most used types of irrigation in the world today.

Localized systems are made to get water close to the ground. This helps to get water to the roots without worrying about evaporation. The pipes are laid between the rows of crops. This is better for crops that cannot endure the flooded field from using a surface irrigation configuration.

Sprinkler equipment is used to simulate rainfall. With this design, the water is pumped through a system and the pipes spray the water into the air. It breaks into small droplets and then falls to the ground much the way a typical rainfall would work. This allows for a nice, even distribution of the water to the crops.

The central pivot configuration also uses the sprinkler system. The equipment is designed to rotate on wheels around a central point, spraying the water out as it moves. It usually takes a full day, depending on the size and speed set, for the equipment to make the full circle. Since the equipment stays in the same place, there is no need to reconnect the hoses as would be needed in the lateral equipment.

The lateral configuration is nearly identical to the central pivot system. The difference is this does not include the anchor point. Instead, the equipment moves along in a straight line. Some have to be manually moved. Another difference is that there have to be water risers placed at intervals so the hoses can be moved and reconnected to maintain the appropriate water pressure. Someone has to monitor the crops and equipment every few hours to make this happen.

Sub-irrigation systems are used to raise the water table under the crops. Typically, the system has a number of underground pipes that will allow water to be transported below ground. This water then is absorbed directly by the root system, rather than having to travel through the surface to get to the roots. This works well in areas that have extreme heat and would have significant evaporation. They also work well for indoor situations where sprinklers and other above ground systems wouldn't work. The excess water is easily collected and reused.

Competition for farmers is strong on a global scale. Because of this, those in the business need to have the right type of irrigation system that will help maximize the growth of the crops and reduce the cost of watering them on a daily basis. With the right equipment, both issues can be addressed, making the crops more competitive.
