An irrigation method comparison

A comparison of drip and mechanized irrigation will illustrate the advantages center pivots can provide both in initial investment and over years of operation.

Crop Yields:

  • Uniformity of drip systems appear to degrade over time, favoring mechanized.
  • Design of drip systems is critical to good water uniformity.
  • Mechanized systems have an edge where salinity is a problem.


  • Center pivots and linear are less expensive to install on large plots and have higher resale values.
  • Drip systems become more cost-competitive in small fields and irregularly shaped fields.
  • Mechanized may last 30 years vs. 10 to 15 for drip, if properly maintained.
  • On-going maintenance costs for drip are three to five times higher than for mechanized.
  • Operating costs for energy are similar, but mechanized typically requires much less labor.


  • Drip often is favored on tall, permanent crops, especially when the field is not laid out to use mechanized systems.
  • Mechanized systems are preferred in sandy soils, where surface application is necessary for germination.
  • Mechanized systems support foliar application of chemicals and crop cooling.
  • Mechanized systems are preferred where frequent crop rotations are used.

Farm Management:

  • Drip systems are less adaptive and forgiving to poor management practices.
  • Drip is more flexible for some existing infrastructure.

Water Efficiency: 

  • Surface Drip Irrigation has slightly higher efficiency than low-energy precision mechanized application (95 percent vs. 90 percent to 95 percent) in research installations.
  • No known studies yet compare actual on-farm efficiency.
