ENERGY REDUCTION THROUGH IMPROVED IRRIGATION PRACTICES

Several methods are presently available to reduce the energy required to pump water for irrigation, including: increased water use efficiency; increased pumping plant efficiency; irrigation scheduling; and reduced pumping pressures. The cost of electricity for pumping can be reduced further by scheduling pumping during times other than the period of peak demand on the utility system. An additional energy saving from improved water management is achieved through a reduction in losses of nitrogen fertilizer by leaching.
