Centre Pivot and Lateral Move Systems

1. What are Centre Pivot and Lateral Move systems?

Centre Pivot system

Centre Pivot and Lateral Move systems are self-propelled irrigation systems which apply water to pasture or crop, generally from above the canopy.

Centre Pivot systems are anchored at one end and rotate around a fixed central point. Lateral systems are not anchored and both ends of the machine move at a constant speed up and down a paddock.

Centre Pivot and Lateral Move systems require an energy source to move water from the source to the plant as well as energy to move the machine on farm.

2. What are the key components of Centre Pivot or Lateral Move systems?

Centre Pivot system Small
Centre Pivot or Lateral Move systems consist of the following components:

A span is the pipe and framework between two towers
A tower supports the spans and contains drive mechanisms and wheels
Outlets are the points at which water exits the main pipes
Emitters are attached at outlets either directly or on rigid or flexible droppers. Water is applied to the plants through emitters
Droppers are rigid or flexible small diameter pipes that allow emitters to be placed closer to the ground
Lateral Move systems share similar technology to pivots and are suited to large rectangular areas - up to 200 ha.

3. What are the advantages and disadvantages of Centre Pivot and Lateral Move Systems?

The advantages are:

Precise application:

The systems are able to apply a prescribed volume of water to match crop water requirements. It reduces the opportunity for surface runoff or deep percolation if the system is designed to match soil infiltration characteristics.

Reduced variability:

The reported application efficiencies for new well designed machines are generally in the 80-95% range, compared to 50-90% for surface irrigation systems.

Lower labour requirements:

Labour requirements are generally lower than surface irrigation but depends on the system and\ or the degree of automation of the machine.

Opportunities for fertigation:

Fertigation allows the targeted application of small quantities of nutrients, with a reasonable uniformity of application and less risk of nutrient losses. The irrigation system may also be used to apply herbicides and pesticides.

Less landforming:

The system can work on rolling topography. However, there might be a need for some landforming for surface drainage or rainfall induced runoff.

The disadvantages are:

Cost:

The systems have a relatively high capital cost compared to surface irrigation systems, unless substantial landforming is required for optimum performance of the surface system. The running costs can also be significant and need to be evaluated during the design process.

Energy requirements:

These systems require some form of energy source (electric or diesel) to operate.

Water quality:

Water may need to be filtered before use to prevent system blockages with sediments. Poor water quality can affect longevity of irrigation infrastructure.

Skill requirement:

Operation and maintenance of these systems will require different skills to those required for surface irrigation systems.
