An improved irrigation system, and better management and operation of the system are the two paths to irrigating with energy efficiency. They will often save you money, too.
The most energy-efficient irrigation methods are drip irrigation, trickle, low-pressure and low-flow sprinklers. Proper maintenance of system components, including pumps, motors, engines, nozzles and fittings is essential for efficient energy use in any system.
Good management of an irrigation system requires understanding irrigation usage and rates, and the irrigation guidelines for crops you grow.
You must also understand how to check soil moisture levels, and track how much water crops use through the growing season.
