Irrigation and pumping are energy intensive practices that add significantly to on-farm costs. Finding energy efficiencies in your irrigation or pumping will save you money and support the environment.
Energy saving options range from the basic to the more advanced (and costly). Simple measures like looking for leaks and regularly servicing your pumps and motors can save energy and money. Reducing the need for pumping may also create significant savings.
Upgrading equipment may mean larger initial outlays but return considerable cost saving, e.g. using a variable speed drive instead of valve throttling for pumping or using smart irrigation sensors.
Here are some useful resources to help you find savings in irrigation and pumping.
